NEW SPECIES OF TROPICAL AMERICAN 

 MOSQUITOES 



(Dipt era, Culicidce) 

 By HARRISON G. DYAR AND FREDERICK KNAB' 



Wyeomyia prolepidis, new species. 



Proboscis rather long, slightly swollen at the tip, black, the 

 labellfe slightly paler ; palpi short, one-sixth the length of the 

 proboscis; clypeus densely clothed with small, flat, dark-brown 

 scales ; membrane of the front more or less prominent between 

 the tori and pale ; occiput with flat back scales and a narrow 

 border of small white ones continuously along the eye-mar- 

 gins, forming a large white patch on the lower part of the side. 

 Prothoracic lobes with flat dark scales, having a dark violet re- 

 flection in some lights ; mesonotum with flat black scales. 

 Abdomen black above, white below, the colors separated on the 

 sides in a straight line. Legs entirely black scaled, with slight 

 bronzy reflections beneath, the femora paler beneath. Pleurae 

 pale brown with large dark brown stains. Wing scales dense, 

 ovate and obliquely subtruncate, all blackish. Length, 3 mm. 



Types, five females. No. 21779, U. S. Nat. Mus. ; Culebra, 

 Canal Zone, Panama, specimens caught by hand (L. H. Dunn). 



Differs from any species known to us by the scales on the 

 clypeus. Nearest in coloration to W. galoa D. & K. and W. 

 cacodela D. & K. ; but in these species the clypeus is entirely 

 devoid of scales. The male, larva and life history are unfor- 

 tunately unknown. This may be Prosopolepis jocosa D. & K.,
