254 EXPERIMENT STATION EECORD. 



Further reports on flies as carriers of infection {Rpts. Local Govt. Bd. 

 [Gt. Brit.], Pub. Health and Med. Subjs., n. scr., No. 102 (1914), PP- S2; abs. in 

 Rev. Appl. Ent., S {1915), Ser. B., No. 6, pp. S8-90).— Three articles are pre- 

 sented in the seventh of these reports (E. S. R., 30, p. 756). 



Do house flies hibenmtef by S. 31. Copeman and E. E. Austen. — Fifty-eight 

 consignments of flies were received from all parts of England in response to a 

 request for specimens of flies, sent out in order to obtain definite information 

 regarding hibernation. These were represented by 94 specimens, as follows: 

 Pollenia rudis, 27; Muscina stabulans, 14; Musca domestica, 12; Pyrellia 

 eriophthalma, 12; Musca corvina, 9; Limnophora septemnotata, 6; CaUipho-ra 

 crythrocephala, 3; Fannia canicularis, 3; Phaonia signata, 2; Dasyphora 

 pratorum, 1 ; Phorbia muscariu, 1 ; Muscina pabulorum, 1 ; Chloropisca notata, 

 1; Blepharoptera serrata, 1; and TephrocMami^ canescens, 1, 



Notes presented as to conditions under which they were found are said to 

 afford no support to the belief that in England house flies hibernate in the 

 adult stage. The few specimens of the house fly were all taken in an active 

 condition. Some of the other flies, however, such as the extremely common 

 P. rudis, were often found partially dormant. 



The destruction of flies by means of bacterial cultures, by J. M. Bernstein. — 

 Experiments were conducted by the author along the line followed by Hesse, 

 who was led in 1912 to the conclusion that Mucor racemosus is polymorphic 

 and that Empusa muscw is merely a parasitic form of it. 



" There can be no doubt that the original statement made by Hesse concern- 

 ing the possiliility of experimentally bringing about the deaths of flies by E. 

 muscw has been verified, but there is much to be done on the subject yet, in 

 order that points still obscure may be satisfactorily cleared up. In the first 

 place the development of the spores of Empusa in moist chambers has not 

 been satisfactorily followed out, nor has the development of M. racemosus 

 from the Empusa spore been proved." 



An investigation of Mr. Hesse's work on the supposed relationship of Empusa 

 musc(P and Mucor racemosus, by J. Ramsbottora. — The author gives an account 

 of the cultivation of spores of E. musco". It is stated that so far as preliminary 

 observations go a single Empusa spore on germination has never given rise to 

 the mycelium and eventually the fruit of .1/. racemosus, and where such have 

 occurred in a culture the mycelium could usually be tracetl to a cluster of 

 spores which might easily have had the smaller spores of Mucor in their midst.

 Woods Hole, 28 (1915), No. 6, pp. 407-460, pis. 2. figs. S). 



One new genus and two new species of Cerambycidae, W. S. Fisheb (Proc. 

 Ent. Soc. Wash., 11 (1915), No. 2, pp. 77-79).— The genus Paratimia and the 

 species P. conicola and Hylotrupes juniperi, the former reared from old cones 

 of Pinus aticnuata in California and the latter from dying juniper (Juniperus 

 pachypliloca) in Arizona, are described. 



A unique type of insect injury, W. R. McConnell (Jour. Econ. Ent., 8 

 (1915). No. 2, pp. 261-267). — An account is given of the bean leaf beetle (Cero- 

 toma trifurcata), the larva of which has been found to feed upon and injure 

 the nodules on the roots of the cowpea in the lower Mississippi Valley. 



The apple flea weevil in Illinois (Orchestes canus), P. A. Glenn (Jour. 

 Econ. Ent., 8 (1915), No. 2, pp. 27.9-286' K— Substantially noted from another
