to the surface of the fruit. Entrance is also made at other places, especially 

 where the fruit has been punctured by the curculio or abrased by limbs or 

 branches or other causes. Owing to the combined effect of the caterpillar and 

 brown rot fungus, a good deal of fruit may fall to the ground, though the 

 majority of the fruit infested by the caterpillars will remain hanging on the 

 trees, especially if the fruit was invaded when nearly mature. The authors' 

 observations are not conclusive as to whether the fruit is preferred to the twig. 



The larvae in general appear to be rather indiscriminate in their choice of 

 pupation quarters and may be expected to choose any place on the trees where 

 protection is afforded. The insect hibernates in the full-grown larval condi- 

 tion in silken cocoons, pupation occurring in the spring. Oviposition com- 

 mences in the spring by the time the shoots of the peach are well out. There 

 are two and prolnxbly three broods of larvse each year. 



A new mosquito from, the eastern United States, F. Knab {Proc. Biol. Soc. 

 Wash., 29 (1916), pp. 161-163). — A new mosquito from Laurence Harbor, N. J., 

 is here described as Ciilex brehmei, and brief notes on its habits are included. 



The fowl midge (Simulium nigritarsis), C. W. Mally [Reprint from Cape 

 Times Weekly [Cape Totcn^, 1915, Oct. 29, folio). — This simulid is said to cause 

 a considerable loss of poultry in the Western Province. It becomes abundant 

 when favorable weather conditions prevail, swarms on the fowls at night, and 

 sucks their blood. 



Egg- disposal in Dermatobia hominls, F. Knab (Proc. Ent. Soc. Wash., 18 

 (1916), No. 3, pp. 119-183). — The autlior presents further evidence to show that 

 the female Dermatobia attaches its eggs to female mosquitoes of species which 

 have a keen appetite for blood, and in such a manner that the larvae hatch out 

 and gain entrance to the host at the point at which the mosquito draws blood. 



The tachinid genus Argyrophylax, W. R. Walton (Proc. Ent. Soc. Wash., 

 18 (1916), No. 3, pp. 189-192, fifjs. .'/). — Two male specimens reared from 

 Nacaleia indicata at Rio Piedras, P. R., have been identified as Argyrophylax 

 albincisa. A description given of the male is accompanied by drawings. 



Notes on the larvae of Euxesta notata, R. H. Hutchison (Proc. Ent. Soc. 

 Wash., 18 (1916), No. 3, pp. 111-111, figs. 5). — The author records the presence 

 of large numbers of larvae of this ortalid at Bethesda, Md., during May, June, 

 and July, in swine dung, in accumulations made up largely of bran and other 

 wastes from feed troughs, and in moist bran alone. 



A monographic study of the parasitic Diptera of Africa, I, J. Rodhain 

 and J. Bequaert (Bui. Sci. France et Belg., 49 (1916), No. 3, pp. 236-289, pi. 1, 

 figs. 1/f). — The first section of this paper (pp. 238-262) deals with (Muscina) 

 Passeromyia heterochwta and the larvae of dipterous parasites of birds; the 

 second section (pp. 262-289) with (Gordylohia) Stasisia rodhaini, the source of 

 a cutaneous myiasis in man, its distribution, hosts, parasites, etc. A bibliog- 

 raphy accompanies both sections. 



Researches on the larvee of cyclorrhaphous Diptera. — The life cycle of 

 Pollenia rudis, parasite of Allolobophora chlorotica. Comparative biology 

 of the larvEe of Diptera, D. Keilin (Bui. Sci. France et Belg., 49 (1915), No. 

 1-2, pp. 15-198, pis. 16, figs. 26).— The first part of this work (pp. 25-106) con- 

 siders the parasitism of earthworms and the life cycle of the cluster fly 

 (P. rudis). The second part (pp. 107-184) relates to the comparative biology 

 of larvae of the Diptera. In two appendixes the parasites of P. rudis and of 

 oligochetes are considered. A bibliography of seven pages is included. 



A preliminary note on the bionomics of Pollenia rudis in America, J. L. 

 Webb and R. H. Hutchison (Proc. Ent. Soc. Wash., 18 (1916), No. 3, pp. 191- 

 199). — ^The authors here give a brief summary of the main points bearing di-
