well with the description of G.» v e x a n s Meig. and with 

 Walker's description of C. s t i m u 1 a n s. It differs from the 

 first in having an unmarked thorax, and only the immediate base 

 of the tarsal jointsi white [fig. 24]. The male alsc has the long 

 claw of the middle tarsus slightly curved, though 

 not sinuous. It may be separated from C. 

 stimulans by the posterior forked cell being 

 wider and shorter than the anterior, while in C. 

 stimulans according to Giles they are of 

 about equal length and breadth. The male differs 

 ^^ciifex fy^iTes^ from the above, in having a white band on the 

 middle of the second joint of the palpus. This is 

 probably Culex sylvestris Theo. though a specimen 

 received from him has the hind claws simple and a lateral white 

 stripe on the side of the head, whereas our form has toothed hind

claws and the lower, lateral portion of the head entirely white, 

 as a rule. A very few specimens agree with the one received 

 from Theobald. It is possible that we have two species. This 

 can be determined only by rearing extensive series. The tarsal 

 bands are much narrower than inC. cantans, and the species 

 is Teadily separated from C. j a m a i c e n s i s by the petiole (in 

 the female) of the first submarignal cell being considerably more 

 than one third the length of the cell. 



Description. The eggs according to Dr Dyar are laid singly or 

 in groups, adhering by capillary action only, floating for a time 

 and ultimately sinking. They are elliptic and fusiform with ends 

 rounded, pointed and about alike, one side more flattened than the
