Genus Chvysoconops, 49 1 



Genus CHRYSOCONOPS. Goeldi. 



Os. Mosq. no Para., p. 114 (1905). 



The head, thorax and abdomen scaled as in Culex. Colours 

 golden-yellow and metallic violet. Large species. Male palpi 

 long, acuminate, dense hair-tufts. Male genitalia with short 

 basal lobes and broad claspers with short acuminate terminal 

 segment, harpogones stout and curved with thick spines. 



The wing scales dense and TaeniorhyncJms-lake, but the 

 majority end asymmetrically. 



Goeldi finds that the eggs of fulvus are short, broad in the 

 middle and taper to a blunt point at each end, almost rhombic in 

 shape. They are laid detached, in a double row which soon 

 becomes disarranged. 



Nine species are known as follows : — fulvus, Wiedemann ; 

 conopas, Frauenfeld ; annettii, Theobald ; aurites, Theobald ; acer, 

 Walker ; brevicellulus, Theobald ; ocftracef*s,Theobald ; fuscopennatus, 

 Theobald, and cristatus, Theobald.
