180 INSECUTOR INSCITLIJ MIJNSTRUUS 



Stripes. Abdomen black above with green and violet reflec- 

 tion ; venter golden scaled with dark median line, last two 

 segments nearly completely dark beneath. Legs without white. 



This species differs from any other Megarhinits by the 

 absence of abdominal tufts and of white on the legs in the 

 female. We saw our specimens emerge from the pupse and 

 the tufts were not left in the pupal skins. 



We have two females, bred from ground Bromeliacese, Dam, 

 January, 1919. 



Megarhinus guadeloupensis guianensis, new subspecies. 



We have one female and one male from different locali- 

 ties which we are not sure belong to the same species. 

 Both, however, come near to Megarhinus guadeloupensis. The 

 female differs by the coloration of the palpi which is sub- 

 stantially silvery blue. The hind legs have white on the fifth 

 tarsal joint also. The male differs in the antennse which are 

 more plumose and bear blue scales on the second joint. 



We hope to give complete descriptions of these species in 

 the near future in a publication on the mosquito fauna of 

 Surinam. Our material will be placed in the collection of the 

 Colonial Institute, Amsterdam, Holland. Cotypes, except of 

 uniques, are also in the collection of the U. S. National Mu- 

 seum, Washington, D. C, and we have added the type num- 

 bers of the specimens so deposited. 



We are much indebted to Doctor Dyar of Washington for 

 his assistance in studying our material, especially our mounts 

 of the male genitalia.
