NOTES ON ENTOMOLOGY 

 EECE>fT parts of the " Genera Inseetorum " 

 include a continuation of W. Horn's Cicin- 

 delidse, fascicle 82 b, pp. 105-208, plates 6 to 

 15, mostly colored; a most excellent review of 

 the tiger beetles. Fascicle 100 is on the Ptero- 

 phoridae, or plume-moths, by E. Meyrick, 22 

 pp., 1 plate, colored, and is also a usefiil re- 

 view. Fascicle 101 is on the large exotic 

 cockroaches of the subfamily Epilamprinae, by 

 R. Shelford, 21 pp., 2 colored plates. Fascicle 

 102 on the ants of subfamily Dorylinse, by C. 

 Emery, 34 pp., 1 plate. Fascicles 103 and 104 

 are by L. B. Prout on the geometrid moths of 

 the subfamilies Brephinse, 16 pp., 1 plate, and 

 (Enochrominee, 120 pp., 2 plates. The latter 

 group is almost wholly from the old world. 

 Fascicle 105 is on the wasps of family Thyn- 

 nidffi, by R. E. Turner, 62 pp., 4 plates (2 col- 

 ored). He makes many new genera, mostly 

 from Australia or South America. Fascicle 

 306 is on the ortalid flies of the group Ulidini, 



by F. Hendel, 76 pp., 4 colored plates of these 

 beautiful insects. He describes two new spe- 

 cies from the United States, Euxesta tenuis- 

 sima (p. 28) from Georgia, and Acrosticta 

 rufiventris (p. 52) from Texas. Fascicle 107 

 is on the minute hymenopterous parasites of 

 the family Belytida^, by J. J. Kieffer, 47 pp., 

 3 plates. 



Major Thos. L. Casey has issued No. 1 of 

 a " Memoirs on the Coleoptera," 205 pp., 1910. 

 This number contains two articles. New Spe- 

 cies of the Staphylinid Tribe Myrmedoniini 

 and Synonymic and Descriptive Notes on the 

 Pffiderini and Pinophilini. He has described 

 365 new species, only a very few being identi- 

 fied with known forms. Most of the species 

 are in the genera Atheta (which he divides 

 into many subgenera) — Sahleta, Batomicra, 

 Colpodota and Strigota. Many of the species 

 are from the eastern states. 



Mr. H. B. Stough is the author of a detailed 

 study of the external morphology of one of the 

 jumping plant lice.' Besides the structure of 

 the body he takes up the wing-venation and 

 color-pattern. He finds that the media and 

 cubitus in nymphal wings are distinctly sepa- 

 rate. From the structure of mouth and geni- 

 talia he concludes that the Psyllidse are more 

 closely related to the Aleurodidae than to any 

 other family of insects. 



Dr. G. Alessandrini has made some experi- 

 ments with the larvae of Piophila casei, known 

 as the cheese-skipper.^ These larvae can pass 

 through the digestive tract of man or dog 

 without greatly delaying development. In a 

 dog the larvse produced lesions of the intestine 

 which facilitated the entrance of pathogenic 

 germs. The larvaB can resist the action of 

 many chemical agents, but the ultra-violet 

 rays retard development. The life-cycle occu- 

 pies about fifty days.
