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. Fig. 32 Wing of C. sylvestris 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.
