232 ENTOMOLOGICAL NEWS. [Sept., '03 



Whatever the collecting may be in other states, we find in 

 North Carolina a happy blending of faunas which makes it a 

 most interesting territory to collect over. Such collecting as 

 we have here described for the latter part of March is scarcely 

 typical of that season, as this spring has been unusually for- 

 ward. Normally this experience would be had in mid- April, 

 but we have not ' ' padded ' ' our account in the least, and have 

 specimens at hand, of all species here recorded as captured. 



The Eggs of the Psorophora Ciliata. 



BY H. F. HARRIS, M. D., Atlanta, Ga. 



Although the larval and pupal stages of the Psorophora cili- 

 ata have been recently described by Prof. Howard, no one, so 

 far as I am aware, has as yet been able to obtain the eggs of 

 this rather uncommon mosquito. 



During October of the past year, while studying the rela- 

 tionship of the various members of the family of Culicidne to 

 malaria, it was my good fortune to obtain a number of eggs 

 from a female Psorophora ciliata which was being used in my 

 experiments. The insect from which the eggs were obtained 

 was captured on October 4, 1902, and was allowed to bite a 

 boy suffering from chronic tertian malaria during the succeed- 

 ing night. The mosquito was then placed in a cage covered 

 by cotton netting, and was supplied with water and a small 

 piece of fresh banana each day. On the morning of October 

 loth, the insect was found upon the surface of the water, 

 which was contained in a small standing dish, and was appar- 

 ently unable to get out. On close inspection there were found 

 lying upon the surface of the water numerous, small, oval, 

 dark-colored, objects that were at once recognized as eggs 

 evidently having been laid by this mosquito which was alone 

 in the cage. These eggs were scattered upon the surface of 

 the water, no two being in contact, and upon examination with 

 a hand lens they appeared to be concavo-convex bodies, the 

 convex surface lying always in contact with the water. 



Under the microscope, as well as when viewed by the unaided 

 eye, the eggs appeared almost black. They measured from
