An Eriococcus on Eriogonum. On July 14, Mr. E. Bethel found a species of Eriogonum at Lake Eldora, Colorado, swarming with a small mealy-bug, and sent a quantity to me alive. On examination the species proves to be Eriococcus bore ili a Ckll., having the characteristic antennæ (7-jointed in this material), denticle on elaw, etc. In some cases the tarsus is as long as the tibia. The living insects, prior to the formation of the sac, are very pale creamy white, with the sides of the b-dy conspicuously hairy. T. D. A. COCKERELI.

Scientific Notes

A Leaf-Cutting Bee from Arizona. In JOURNAL OF ECONOMIC ENTOMOLOGY, April 1913, p. 195, Mr. A. W. Morrill called attention to the injury done by bees of the genus Megachile in Arizona. More recently he has sent specimens which he received from Salome, Arizona, to Mr. J. C. Crawford, who has forwarded them to me for identification. They were collected at Salome, May 20, 1913, and were said to be quite destructive. The species proves to be M. lippiæ, differing a little from the New Mexico type in the pale hair of the ventral scope being clear white, instead of somewhat yellowish. As M. lippie was originally described as a variety of M. cleomis, with only comparative notes, it may be well to publish a description which will enable it to be recognized by those who have no M. cleomis. In general, the females look like those of M. addenda and generosa (of which cleomis is a subspecies), but when the abdomen is seen from above, only the last two segments show black at sides in lippia, while in the others mentioned segments 2 to 6 show black.

Megachile lippia (Cockerell). Female, length about 14 mm.; moderately robust, the abdomen not parallel-sided; black with the pubescence nearly all white, but some black on vertex, mesothorax and scutellum, on subapical margin and extreme sides of fifth abdominal segment, at sides of sixth segment, and on last ventral segment except basally; head very broad, the large reddish-brown eyes diverging above, the lunar orbits above conspicuously concave; face with much white hair, very dense and spreading at sides; mandibles broad, quadridentate, but the innermost tooth little developed; lower margin of clypeus quite simple; clypeus shining but well punctured; flagellum marked with dark red beneath; mesothorax not very hairy, and wholly without white lines of hair in front, its greater part closely and finely punctured, but the posterior middle with more separated punctures and in the Arizona form somewhat shining; tegulæ rufopiceous, the margins lighter; wings hyaline, broadly dusky on apical margin; legs with white hair, that on inner side of basitarsi pale orange, and on small joints of tarsi coppery-tinted; hind basitarsi moderately broadened; abdomen shining, finely punctured, with narrow white hair-bands; last dorsal segment nearly straight in lateral profile, pruinose, with fine short greyish-white hair, but at sides with long erect black hair.

A Parasite of the Chinch Bug Egg. In the experiments conducted this year to determine the time of the first appearance of young chinch bugs and the mortality of the eggs, a large number of eggs were collected in the field for examination. The eggs which were collected at different intervals and in different localities were examined daily. While thus examining the eggs it was noticed that some of them became dark in color instead of assuming the usual red coloring. These eggs were isolated and on May 19, there emerged from them three parasites. With these three parasites as a basis, the life history was carried through four generations, running up to July 5. Since this was the time between the two broods of the chinch bug, it became impossible to obtain additional chinch bug eggs with which to continue the work. From July 5 to July 23 only an occasional parasitized egg was found in the field, but beginning with the latter date, parasitized eggs were found in large numbers in the corn fields and the second generation was obtained by August 10. Up to the present date this year over 275 individual parasites have been bred out. The length of the life cycle has been found to vary from ten to eighteen days, depending on climatic conditions.

The parasite has been found in every wheat and corn field examined around Manhattan. Of 3,101 eggs collected between April 28 and June 10, the average percent of parasitism was 20.8, and of 116 eggs collected at Crawford (central Kansas) 19 eggs or 16.3 were parasitized.

The work is still under way and a full description of the parasite together with notes on its life history and efficiency will be published later. Mr. Crawford of the U. S. National Museum concludes that this parasite represents a new genus and species of the Proctotrypida.

Swarming of Hemiptera. On the evening of July 1 of the present year, Boulder. Colorado, was visited by incalculable numbers of Lygaus facetus Say. Coming home at about 10.30 p. m., I found them in clouds about the electric lights, presenting the same appearance as the Trichoptera at certain seasons in the vicinity of the great lakes. They exhaled a strong and disagreeable cimicoid odor. In some parts of the town, I was informed, they were swept up with brooms. The weather here has been exceedingly hot and dry for many weeks, and one can only suppose that the bugs were compelled to migrate owing to the drying up of their usual food supply. Once before, in Boulder, I have observed a similar phenomenon, the species in this case being Homopterous. On September 21, 1908, I found on the steps and in the basement of the University of Colorado library enormous numbers of Homoptera, mostly dead. I nearly filled a small mason jar with them, and could have secured many more. The great majority, probably at least 90 per cent, were Xerophiza viridis (Fabr.). The only other species at all abundant was Limotettir exitiosas Uhler. Agallia uhleri V. Duzee was the next in numbers. There were also sotze miscellaneous insects, including two Nysius angustatus Uhl., and one Lygous facetus Say. The Xerophlea viridis were nearly all of the green form, but pink and light brown individuals occurred in small numbers. The brownish variety is doubtless var. grisea (Germar). The species X. viridis ranges from Massachusetts to Brazil. The swarming of a Lepidopterous insect, Homœosoma electellum, at Boulder, has already been recorded in Entomological News.

Observations Regarding Flight of the Cotton Moth in 1911. In 1911. certain work on the canal of the Bulls Bridge power plant at Merwinsville, Conn, necessitated day and night work and to facilitate the latter we had a number of electric are lights at the two points where work was progressing, there being six arra at one point in a stretch of 300 feet and 10 or 12 lights at the other point in a section about the same length, perhaps 200 feet wide, both localities being in the valley of and close to the Housatonic River. On September 23, in reporting conditions at the work my representative stated there were "millions of moths" around the lamps and on Monday, the 25th, when I personally visited the work I found every one of the wooden frames, from which the are lights were suspended (these frames consisting of an upright 4′′ x 6′′ and perhaps 10 feet high and a cross arm at the top about 5 feet long, from which the lamps were hung, covered with moths for the most part as closely together as they could get. These were almost entirely cotton moths, There were, however, 30 to 40 specimens of Tol ¡pe relleda, four or five Sphinx moths, several Catocalas and a few other species. The ground surrounding these lights was also completely covered with the moths and when disturbed they made a noise like the rustling of dry leaves. The superintendent reported that for two or three nights previously there had been far more than I found Monday morning; that at times
