As a result of these experiments it was found possible artificially 

 to infect Anopheline, and to a less extent, Culicine mosquitos with 

 these encysted parasites, which, however, did not undergo any marked 

 development in this host. Developmental forms occur in certain 

 fresh-water fish that have become infected either naturally or arti- 

 ficially. ■ The fully-mature, egg-laying stage has not yet been met 

 w^ith, but it probably occurs in some aquatic bird that feeds on the 

 infected fish. The structure of the adult stage of the parasite as 

 developed in the fish shows that it closely resembles a CUnostomtim 

 of the family Fasciolidae ; the exact species, however, has yet ta 

 be determined.

 Muscid. — Indian Jl. Med. Research, Calcutta, v, no. 3, Januarv

Ochromyia jejuna is a large Dipteron, common in Madras, and pro- 

 bably in most parts of India during the hot weather. This fly has been 

 recorded as attacking swarming Termites, but at Pusa its attention 

 seems to be confined to ants. These it attacks when they are trans- 

 ferring their larvae from one place to another. 



This predaceous habit accounts for the modification of the mouth- 

 parts, which are remarkable for the specialisation of the proboscis to 

 function as a prehensile organ and for the size and development of the 

 dental armature. 



The life-history of the fly is unknow^n, but in view of its predaceous 

 habits and the similarity of its mouth-parts to those of the blood- 

 sucking Diptera, its close relationship to Auchmeromyia luteola, which 

 is a blood-sucker in the larval stage, is of interest.

 parts. — Indian Jl. Med. Research, Calcutta, v, no. 3, January

Another paper on this subject has recently been noticed [see this 

 Review, Ser. B, vi, p. 99]. 



The conclusions here arrived at are : — That the female of Pangofiia 

 (Corizoneura) longirostris is a blood-sucker as well as a flower-feeder. 

 The labium is not utilised in the sucking of blood. The insect requires 

 to settle upon its host in order to pierce the skin and suck blood.

Philaematomyia indica, sp. n., described in this paper is the first 

 larviparous species of the genus to be recorded. Being a rare fly it has 

 not yet been proved to be a true blood-sucker, as have P. crassirostris 

 {insignis) and P. gurnei, though the structure of its mouth-parts renders 

 this probable. The larvae are deposited in fresh cow dung, within 

 pupation occurs after four or five days, the fly emerging seven days 

 which later. 



A key to the genus is given, based on the form of the genital armature.
