ARTHROCNODAX CAROLINA N. SP.

By E. P. FELT, Albany, N. Y.

The species described below is allied to A. apiphila Felt from which it is easily separated by the lighter circumfili and the longer stems of the antennal segments in the male. It is easily separated from A. occidentalis Felt, a species recorded as preying upon red spider in California, by the shorter stems of the antennal segments in the male and by the rounded ventral plate. Mr. E. A. MacGregor, who regresi this species in both 1912 and 1913 from red spider on cotton, is of the opinion that it is the most important natural agent in controlling this pest.

Male Length 75 mm Antennæ about as long as the body, sparsely hairesi light brown, 14 segments, the fifth having the two parts of the stems with a length three-fourths and one and three-fourths times their diameters, respectively

circumfili are normally developed and not unusually thick or heavy. Mesonotum dark reddish brown. Scutellum and postscutellum yellowish. Abdomen yellowish brown. Halteres, coxa and femora basally yellowish or pale straw, the distal portion of femora, tibiæ and tarsi slightly darker; claws slender, strongly curved, simple; pulvilli nearly as long as the claws. Genitalia; basal clasp segment long, stout, terminal clasp segment long, tapering; dorsal plate long, broad, deeply and triangularly emarginate, ventral plate short, broadly rounded.

Female. Length .75 mm. Antennæ extending to the fourth abdominal segment, sparsely haired, fuscous yellowish; 14 segments, the fifth with a stem one-fifth the length of the cylindric basal enlargement, which latter has a length a little over twice its diameter and sparse whorls of stout setæ basally and apically; terminal segment slightly produced, with a length over thrice its diameter, broadly rounded apically. Palpi; the third segment with a length about two and a half times its diameter, narrowly oval, the fourth segment one-fourth longer than the third, more slender. Color nearly as in the male, except that the thorax and abdomen are more orange. Ovipositor short, the terminal lobes narrowly oval and thickly setose. Color characters from microscopic preparations and, therefore, of only approximate value. Type Cecid. a2461.

Lepidoptera Breeding on Evening Frimrose. Last year I found an interesting large-flowered evening primrose (Oenothera hewetti Ckll., Proc. Biol. Soc. Wash., XXVI, p. 203) in New Mexico, and secured a living plant for my garden at Boulder, Colorado. This plant, in the summer of 1913, grew to a very large size, and furnished the material from which the species was described. When gathering the seeds, I removed large numbers of whole pods, to save time, and presently (October) found that many small moths were issuing from them Most of these were Mompha brevivittella Clemens, but several were strongly marked with white, and belonged to Mompha circumscriptella Zeller. Although the moths were so abundant, they did not prevent me from getting enough seed to supply all my correspondents interested in Oenothera. It must be considered doubtful whether they are really injurious, since the normal crop of seed is enormously greater than would be required for the prosperity of the plant, supposing only a small fraction to grow. A third Mompha, M. pecosella Busck, has been found by me on the University Campus at Boulder, but it has not been bred. I am indebted to my kind friend Mr. Aug. Busck for the determination of all the moths. He tells me that at Dallas, Texas, Mr. W. D. Pierce bred M. circumsciptella from Galpinsia hartwegi. Doubtless the species of Mompha feed on various evening primroses, and presumably the common native host of those attacking Oe. hewetti in my garden is our very abundant Oe. cockerelli Bartlett in de Vries, 1913.

CORRECTION

CHINCH BUG EGG PARASITE. There seems to have been a somewhat ambiguous and unsatisfactory statement edited into the scientific note appearing on pages 425– 26. The original stated in effect that Mr. A. B. Gahan (who will describe the species) concluded that the parasite represented a new genus and species of the Proctotrypida, a finding confirmed by Mr. Crawford of the United States National Museum.

JOURNAL OF ECONOMIC ENTOMOLOGY

OFFICIAL ORGAN AMERICAN ASSOCIATION OF ECONOMIC ENTOMOLOGISTS

DECEMBER, 1913

The editors will thankfully receive news items and other matter likely to be of interest to subscribers. Papers will be published, so far as possible, in the order of reception. All extended contributions, at least, should be in the hands of the editor the first of the month preceding publication. Contributors are requested to supply electrotypes for the larger illustrations so far as possible. The receipt of all papers will be acknowledged.-EDS.

Nearly seven years have elapsed since the economic entomologists assembled at New Orleans. They have been years of progress and prosperity, at least so far as entomological developments in the southern part of the country are concerned. The Atlanta gathering will be largely attended by southern entomologists, and the investigator located in the north will have at this meeting a most excellent opportunity of talking with the men who are doing things in the warmer sections of this country, and through them obtain a better idea of their special problems. Entomologists at a distance are strongly urged to make an effort to be present and take part in a meeting which promises to be one of the most successful of recent years.

The stable fly, formerly held as a comparatively innocuous insect. stands convicted as a carrier of infantile paralysis and now the finger of suspicion has been pointed at it in connection with the mysterious Pellagra, an infection which some have thought might be carried by species of Simulium. American investigations of this latter genus have failed to produce conclusive evidence of complicity on the part of Simulium, and it now remains to be seen if this latest arraignment will be followed by indictment. There is still much to be learned concerning the Diptera and it is to be hoped that the interest aroused in the groups containing pathogenic forms will be extended and result in studies of the numerous unknown flies and the bringing of our knowledge concerning the order up to a state comparable to that relating to the Coleoptera, Lepidoptera or Hymenoptera.
