(Phlehotonms minutus) were found to be infected with a flagellate of the 

 genus Ilei'petomonas. It is probably a natural parasite of the fly and is not 

 likely to have any relation to the occasional habit of Phlebotomus as a human 

 bloodsucker. The natural host of P. minutus, as Ilowlett has shown, is prob- 

 ably the common wall lizard. As I can not find that the flagellate has been 

 previously described. I suggest for it the name Hcrpctomonas i)JilcbotO)ni n. sp." 



New investigations of the life history of the two warble fl.ies of cattle, 

 H. Glaskb {Mitt. Aussch liases Belcampf. Dasselplage, No. 5 (1913), pp. 5-38; 

 ahs. in Intcrnat. Inst. Agr. [Rome'\, Mo. Bui. Agr. Intel, and Plant Diseases, 

 5 {IDlJf), No. 3, pp. 376, 377). — The author here reports upon further investi- 

 gations (E. S. R., 29, p. 761) of the life history of Hypoderma hovis and E. 

 lineata. In experiments conducted in order to determine if the larvae of the 

 two warble flies are able to penetrate the skin of man and of animals, negative 

 results were obtained with cattle but in man in one case a larva penetrated 

 the skin of the thigh.

A new sarcophagid parasite of grasshoppers, E. O. G. Kelly {U. S. Dept. 

 Agr., Jour. Agr. Research, 2 {1914), No. 6, pp. 435-446, pi. 1). — This paper 

 reviews the literature relating to the parasitic species of the dipterous family 

 Sarcophagidfe and reports investigations carried on by the Bureau of Ento- 

 mology of this Department, particularly in Kansas. 



The studies have shown that sarcophagid larvse are placed on the underside 

 of the unfolded posterior wings of the flying grasshopper, the striking of the 

 wing by the fly probably causing the sudden dropping of the victim that has 

 been observed. After having been deposited on the unfolded wings of the 

 grasshoppers the maggots crawl toward the base of the wing, using the sides 

 of the fold for a trough in which to travel. In this way they reach the base of 

 the wing and the metathorax, where the body is quite soft and moist, and 

 enter the body to feed upon the internal vital organs. Some of the maggots 

 are deposited on segments of the abdomen and these enter through the seg- 

 mental divisions. They develop rapidly, maturing in from 10 to 30 days. 

 After becoming full grown the larvse crawl from the body of the grasshopper 

 and enter the soil to a depth of from 2 to 6 in., where they pupate. It is 

 stated that nearly 1,200 sarcophagids of several siiecies issued from the bodies 

 of some 800 dead grasshoppers collected during the fall of 1912. Adults began 

 to issue about the middle of February and continued to do so until early 

 May. There appear to be five or six generations each year. 



Sarcophaga kcllyi n. sp., a description of which by J. M. Aldrich is appended, 

 was the species upon which the observations were largely made. Several other 

 less abundant species were observed in the act of larvipositing on grasshop- 

 pers and were subsequently reared from them during these investigations, 

 notably, 8. cimhicis, 8. sarracenia; and S. hunteri, and in addition to these S. 

 helicis was reared from the dead grasshoppers. Several parasites of the sar- 

 cophagid puparia were reared, including Pcrilampus hj/alinus, ChaJcis coloraden- 

 sis, Apha^reta sp., and Eupteromalis sp. 



Papaya fruit fly, F. Knab and W. W. Yothers {U. 8. Dept. Agr., Jour. Agr. 

 Research, 2 (1914), No. 6, pp. 447-454, pis. 2). — Toxotrypana cut^'icauda was 

 first brought to the attention of this Department as occurring in Florida 

 in December, 1905, when infested fruit was received from ^liami. It was 

 again reported during the summer of 1912 from the same locality. The in- 

 creasing commercial importance of the papaya led to an investigation during
