bred from upper side mines on leaves of C cuneatus in Placer County ; Buccu- 

 latrix transversata, bred from leaves of Amhrosia psylostachya ?n Los Angeles 

 County; Gracilaria reticulata, the larva of which rolls under the apex of 

 leaves of Q. agrifolia in Mills College; and 0. pahtstriclla, bred from mines 

 on leaves of a species of Salix in Mills College. 



The life history of Cricula trifenestra, J. H. Stebbins. Jr. (Ent. News, 21 

 {1910), No. 3, pp. 101-103). — This species, bred from eggs received from India, 

 was found to be double brooded. 



The larva and food-plant of Glyptocera consobrinella, H. G. Dyar (Proc. 

 Ent. Soc. Wash., 12 (1910), No. 1, p. 5^),— The larviB of this phyoitine were 

 found upon the leaves of Viburnum lentago at Lincolnville, Me., in August. 

 They spun up in September and the adults issued the following spring. The 

 larvfe eat the whole leaf, often webbing to the stem and cutting the midrib. 



Two new species of Lsetilia, II. G. Dyar (Proc. Ent. Soc. Wash., 12 (1910), 

 No. 1, p. 5't). — Lwtilia mycrsellu and L. cremiella, the first named bred from 

 scale insects collected from pine at Rockville, Pa., and also at Tryon, N. C, are 

 described as new. 



Schizomyia ipomoese, E. P. Felt (Ent. News, 21 (1910), No. J,, pp. 160, 

 161). — This species was reared in large numbers at St. Vincent, British West 

 Indies, from the flower buds of Ipomcea. 



[Notes on mosquitoes], S. T. Darling (Jour. Trop. Med. and Hyg., 13 (1910), 

 No. 1, p. 12). — The author finds that with the species with which he has worked 

 (Anopheles albiinanus, A. pscudopunctipennis, and Stegomyia calopus) the de- 

 sire to suck blood is not dependent upon the presence in the spermathecfe of 

 the female of the spermatozoa of the male. Females, isolated as they emerged, 

 would, after 24 hours, puncture and suck blood as greedily as fecundated ones. 

 "Specimens of A. pseudopunctipennis did not bite with alacrity; but this 

 mosquito, I have found, does not visit quarters to the same extent that A. albi- 

 manus does, and in my infecting experiments only 12 per cent of .1. pseudopunc- 

 tipennis became infected after biting, favorable cases of malarial fever, while 

 60 per cent of A. albimanus became infected. This might be interpreted as 

 meaning that blood sucking is not a confirmed habit with A. pseudopuncti- 

 pennis. . . . 



" Males have lived for 15 to 19 days, frequently outliving females when both 

 were subjected to a raisin or date 'diet, the females not being permitted a blood 

 feeding. When the male has suitable food he appears to live in captivity fully 

 as long as females do. This is based on observations with A. pseudopuncti- 

 pennis, A. albimanus, Gulex cubcns, and »*?. calojms." 



Notes on the mosquitoes of Arkansas, J. K. Tiiibault, Jr. (Proc. Ent. Soc. 

 Wash., 12 (1910), No. 1, pp. 13-26).— This account includes an annotated list of 

 mosquitoes of Arkansas in which observations made during four seasons (1906- 

 1909) are reported. 



A preliminary note on the prevalence of mosquitoes in Cairo and its 

 environs, F. C. Willcocks (Ann. Trop. Med. and Par., 3 (1910), No. 5, pp. 583- 

 r,^()y — Notes on the occurrence and habits of a number of species. 



The g'enus Tachydromia, A. L. Melander (Psyche. 11 (1910). No. 2, pp. 

 J,l-62, pt. l).—\ table of the genera and subgenera of the Tachydromiia\ also 

 one for the separation of the North American species of the genus Tachydromia, 

 descriptions of which follow, are here presented. Six new forms are described. 

 A catalogue of the 33 described species of the genus is included. 



The effect of mosquito larvae upon drinking water, R. Boyce and F. C. 

 Lewis (Ann. Trop. Med. and Par., 3 (1910), No. 5, pp. 591-59.',).— The experi- 

 ments here reported consisted in placing larvae of Cutex spp. and of Theobaldia 

 annulata in a flask of nousterilized drinking water, and comparing from day
