REMARKS ON PSOROPHORA CILIATA, WITH NOTES ON 



ITS EARLY STAGES. 



BY L. O. HOWARD. 



Psorophora ciliata, Fabr., is the only species of the genus Psoro- 

 phora known to occur in the United States. It is a widespread species 

 and is known to the writer to occur in Massachusetts, New Jersey, 

 Pennsylvania, District of Columbia, Virginia, Kentucky, Illinois, Florida, 

 Louisiana, Arkansas, Nebraska, Texas and California. It is, however, rare 

 in its northern range and seems to be a lower austral form. It may have 

 a tropical range, but among many mosquitoes received by the writer 

 during the past year from Mexico, Nicaragua and Cuba, this species does 

 not occur. In his " Notes on the Mosquitoes of the United States " 

 (Bulletin 25, New Series, Division of Entomology, U. S. Department 

 of Agriculture), published August 23rd, 1900, the writer calls attention to 

 the fact that Psorophora and Megarhinus have not been studied by 

 investigators engaged in working upon the transfer of Haematamoebae by 

 mosquitoes, and urges that physicians and bacteriologists in our Southern 

 States pay some attention to the mosquitoes of these genera. 



At the time when the bulletin was written nothing was known about 

 the early stages of Psorophora. A large series of living specimens was 

 captured in June of the present year at St. Elmo, Va., by Mr. Pratt, and 

 we expected that we should be able to secure eggs without difficulty and 

 to study the insect m its different stages. The females were placed alive 

 in large battery jars, under conditions which had repeatedly been success- 

 ful with Culex and Anopheles, but no eggs were deposited. This brought
