NEW MOSQUITOS FROM PANAMA. 



By C. S. Ludlow, 

 Army Medical Museum, Washington, D. C.

 work at Army stations both in this country and abroad, some new 

 forms belonging to different groups of mosquitos have been received 

 at the Army Medical Museum, two of which are from Panama and 

 the others from the A. E. F.-S. taken at four different stations in 

 Siberia. 



There have also been received from Siberia three species already 

 described by Mr. Theobald, "Cvlicida togoi,'' ''Cidicida nipponi,'"

Female. Head: dark brown, practically black, covered with 

 fine "tomentum," a frosty line around the eyes, a tuft of long 

 slender white scales projecting forward between the eyes, white
