C. quinqucfaficiatus, multiply most rapidly in the presence of highly polluted 

 water, and discuss an outbreak investigated that had its origin at sewage- 

 disposal plants. 



Stomoxys calcitrans, A. Rutherford (Trap. Agr. [Ceylon], /,2 (191.'t), No. 3, 

 pp. 222-225). — This comprises notes on the stable fly (.S. calcitrans) with 

 quotations from the literature. The born fly {HccmatoMa serrata) also occurs 

 in Ceylon 



On a larva of a species of MuscinEe, living in the nest of Passer griseus in 

 the Kongo, J. Rodhain {Rev. Zool. Afric. [Brussels], 3 (lOl/f), pp. 213-217, 

 fig. 1; abs. in Rev. Appl. Ent., 2 (1914), Ser. B, No. 4, p. 69).— Larvae and pupse 

 of a fly belonging to the subfamily Muscinte were taken from the nests of the 

 gray-headed sparrow (P. griseus) and upon examination the larvfe were found 

 to contain avian blood. 



Inheritance of the length of life in Drosophila ampelophila, R. R. Hyde 

 {Proc. Ind. Acad. Sri., I'JIS, pp. 113-124, figs. 5).— The conclusions drawn from 

 the author's investigations with the pomace fly are in part as foUow'S : 



" Hybrids between the truncate stock and the inbred stock are more vigorous 

 than either parent, as .shown by the fact that the hybrid lives 47 days while 

 . . , the flies from the truncate stock , . . live 21.4 days, the females live 18.4 

 while the males live 26.4 days. The flies from the inbred stock live 37.4 days. 

 The females live 34.5 days while the males live 40.5 days. The shortened length 

 of life of the truncate stock reappears among the grandchildren after skipping 

 a generation wlien crossed to the inbred stock. . . . Those descended from the 

 truncate grandmother lived 29.5 days. The males lived 32.8 days and the fe- 

 males lived 25.9 days. The flics descended from the truncate grandfather lived 

 29.3 days. The males lived 31.1 days, while the females lived 27.3 days. It seems 

 not improbable that the length of life and the coming to maturity of the germ 

 cells may be in some way physiologically connected." 



Cane grub and muscardine fungus at Cairns, H. Tryon (Queensland Agr. 

 Jour., n. ser., 2 (1914). No. G, pp. 402-405).— The author states that Metar- 

 rhizium anisopliw is indigenous to Queensland. 



[Keport of] division of entomology, H. T. Easterby (Ann. Rpt. Bur. Sugar 

 Expt. Stas. [Queensland], 1914, pp. 55-57). — A brief statement is presented by 

 A. A. Girault of the results of work with the so-called grub pest or cane beetle 

 (Lepidiota alhohirtum), details relating to which will be published later as a 

 bulletin. 



Wireworms attacking cereal and forage crops, J. A. Hyslop ( U. S. Dept. 

 Agr. Bui. 156 (1915), pp. 34- figs. S). — In an introduction the author gives a 

 brief account of the feeding habits of the true wireworms (Elateridie), and also 

 of the false wireworms (Tenebrionidie). Several hundred species of Elaterid.ie, 

 which vary enormously in their habits, occur in North America ; the majority 

 attack the roots of plants but some live in dead and rotten wood (Alaus, Elater, 

 Adelocera, etc.) and still others (Alaus, Hemirhipus, Adelocera, etc.) are pre- 

 daceous. Some species abound in heavy moist soil filled with humus (^Nlela- 

 uotus, Agriotes, etc.), some prefer well-drained soils (Corymbites), and still 

 others (Horistonotus) are most destructive on high sandy land which is very 

 poor in humus. It is stated that the large luminous elaterid of the West 

 Indies (Pyrophorus luminosus) is a decidedly beneficial insect, since it feeds 

 on the Lachnosterna larvje in the sugar cane fields. 



Brief accounts are given of the life history, habits, injury, occurrence, and 



remedial measures for some of the more important species, including the wheat 



wirew^orm (Agriotes mancus), the corn and cotton wireworm (Horistonotus 



uhlerii), the inflated wii'cworm (Corymiites inflatus), the dry-land wireworm
