NOTE ON AEDES FULVUS WIEDEMANN 



(Diptera, Ciilicidcc) 



By HARRISON G. DYAR 



The male of this species, missing in the monograph (How- 

 ard, Dyar & Knab, Mosq. No. & Cent. Am. & W. I., iv, 625, 

 1917), is now at hand. The coloration agrees with that of the 

 female, as also the short raised scales on the hind tibiae. 



Hypopygium. Side pieces long and slender, over four 

 times as long as wide, slightly curved, rounded at tip ; an open 

 tuft of long hairs inwardly at the outer fourth. Clasper 

 slender, with long terminal spine. Apical lobe moderate, run- 

 ning to the base, nude, except for two small setse at the upper 

 angle. Basal lobe divided, the lower part quadrate, bearing a 

 very long stout spine, swollen in the middle ; upper part ellip- 

 tical, free, finely setose all over, resembling a cactus-leaf. 

 Claspette stem slender, rather long, narrowed slightly on the 

 outer third ; filament widely expanded, the expansion broadest 

 at the base, the tip shortly hooked. Tenth sternites moderate, 

 the tips bluntly pointed. Aedoeagus conical, weakly chiti- 

 nized. Ninth tergites short and broad, oblique on the inner 

 side, each with about ten setae.
