ECONOMIC ZOOLOGY ENTOMOLOGY. S63 



A few notes on the habits of parasitic Hymenoptera, W. D. Pierce and 

 R. A. CusHMAN (Proc. Ent. Soc. M'asJi., 17 (1915), No. 3, pp. 164-167). 



Descriptions of new Ichneumonidae and taxonomic notes, li. A. Cushman 

 (Proc. Ent. Soc. Wash., 17 {1915), No. S, pp. 132-U2) .—This paper consists 

 largely of descriptions of new species of economic importance, together with 

 notes on previously described species and genera. Among the new species of 

 importance are Calliephialtes thurherm from Anthonomus grandis thurberiw 

 in the Santa Rita Mountains, Arizona ; Trematopygus eriocampoididis from 

 Caliroa (Eriocampoides) cerasi, and Omorgus tortricidis from Polychrosis 

 viteana at North East, Pa.; and O. plithorimoca from Phthorimxca operculella, 

 at Pasadena, Cal. The genus Prosmoridea is erected for Prosmorus elotigatus. 



The genus Secodella in North America, J. C. Crawford (Proc. Ent. Soc. 

 Wash., 17 (1915), No. S, pp. 142-144)- — The author recognizes five species, of 

 which four are described as new to science, namely, Secodella cushmani from 

 Polychrosis viteana at North East, Pa. ; S. acrobasis from Acrobasis nebulella 

 at Monticello, Fla. ; S. rugosus from Oswego, N. Y. ; and S. viridis from an 

 unknown locality. 



An insect enemy of the four-lined leaf bug (Pcecilocapsus lineatus), C. R. 

 Crosby and R. Matheson (Canad. Ent., 47 (1915), No. 6, pp. 181-183, figs. 4). — 

 The larva of a hyraenopteran found at Ithaca, N. Y., to burrow through the pith 

 of Weigelia stems until it reaches a row of eggs of P. lineatus and then to eat 

 and destroy them, is described as Cirrospilus ovisugosus n. sp. 



A new genus and species of Trichogrammatidae from the Philippines, A. A. 

 GiBAULT (Canad. Ent., 47 (1915), No. 7, pp. 233, 234) .—Pseudobrachsticha 

 semiaurea, reared from the eggs of Hilda breviceps at Los Banos, Philippine 

 Islands, represents a new genus and species. 



Further data on the life economy of the chinch bug egg parasite, J. W. 

 McCoLLOCH and H. Yuasa (Jour. Econ. Ent., S (1915), No. 2, pp. 248-261, figs. 

 S). — A detailed report of life history studies of Eumicrosoma benefica, a brief 

 account of which has been previously noted (E. S. R., 31, p. 354). Collections 

 of eggs were made in 16 localities in Kansas during July and August, and the 

 average parasitism for the State, exclusive of Manhattan, was 14..5 per cent. 



New species of Aphidiinse, a subfamily of plant lice parasites, H. L. 

 ViERECK (Mo. Bui. Com. Hort. Cal., 4 (1915), No. 5-6, pp. 285, 286).— The two 

 new plant lice parasites here described, namely, Epliedrus wstivaUs and Morv- 

 octonus secundus, make a total of 11 species of the subfamily recorded from 

 California. 



A new species of Campoplex, H. J. Franklin (Ent. Netvs, 26 (1915), No. 8, 

 pp. 356, 357). — Campoplex variabilis, which was found to parasitize from 25 

 to 30 per cent of the larvae of Epelis truncataria faxonii at Wareham, Mass., is 

 described as new to science. 



The peculiarities of development of Collyria calcitrator, N. V. Kubdiumov 

 (Trudy Pervago Yseross. Stezda Dteiatel. PriJcl. Ent., Kiev, 1913, pp. 94-96; 

 abs. in Rev. Appl. Ent., S (1915), Ser. A, No. 5, p. 237). — This ichneumonid, one 

 of the principal parasites of the wheat sawfly (Cephus pygma^tis) and fre- 

 quently destroying 75 per cent of its larvae, has been found through experi- 

 ments at the Poltava Station to oviposit in the egg of its host. The egg of the 

 parasite develops very slowly and produces a larva in the body of the larva 

 of the host, where it winters and destroys its host the following spring. 



A destructive pine sawfly introduced from Europe (Diprion [Lophyrus] 

 simile), W. E. Britton (Jour. Econ. Ent., 8 (1915), No. 3, pp. 379-382, pi. 1). — 

 This important European sawfly has been found to occur on pine in nursery 

 at New Haven, Conn., where it appears to have become established.
