100 SCIENTIFIC REPORTS OF THE AGRICULTURAL RESEARCH 



" One freshly-laid egg-mass of C. stimulans was found 

 on 8th February. 



' Eleven egg-masses of C. stimulans were obtained on 

 15th February; no parasite emerged out of them. 



" One adult T. albimedius was seen on 20th February. 



" Three old egg-masses of T . crassus were obtained on 

 23rd February, but no trace of parasites was seen amongst 

 them. 



" Three freshly-laid egg-masses of T. albimedius were 

 obtained on 23rd February, and by 27th February 71 para- 

 sites emerged from these egg-masses. 



" One egg-mass of T. bicallosus was observed on 23rd 

 February with one parasite on it; it was kept under 

 observation and seven parasites were found to emerge on 

 1st March. 



" Between 25th and 26th of February 91 egg-masses 

 were collected; they belonged to T. albimedius, T. virgo, 

 T. bicallosus and C. stimulans. 



" Egg-laying of Tabanids was noted in large numbers 

 at Birouli ghat where the Estate cows were accustomed to- 

 graze. 



" Besides the foregoing, work on the parasites of birds 

 was continued at Pusa, the following parasites being 

 obtained from different nests :— (*) Two species of blood- 

 sucking midges of the genus Culicoides were found in very 

 large numbers in crows' nests. The nest of a crow was 

 invariably found lined with horse hairs and "the midges 

 were found inside the hairs quite inflated with blood. The 

 members of the genus Culicoides are in the habit of draw- 

 ing more blood than they can carry on the wing ; I have very 

 often marked these flies quite incapable of flying after their 

 meal of blood. About 6 per cent, of the crows' nests were 

 found infested with blood-sucking midges whereas the nests 

 of several other birds which were examined on various 

 occasions did not reveal the presence of these midges. 

 (it) Squirrel bug: This bug has proved to suck blood of 

 man, rabbit and goat under Laboratory conditions. It was 

 found mainly inside the nests of squirrels. It belongs to.
