XO. 1822 NEW SPECIES OF AMERICAN MOSQUITOES 255 



CULEX ELOCUTILIS, new species 



Female. — Proboscis moderately long and slender, somewhat 

 swollen towards the apex, black-scaled ; palpi black-scaled. Occiput 

 clothed with dark scales with bronzy luster, margin of the eyes nar- 

 rowly white. Mesonotum uniformly dark brown-scaled with a 

 bronzy luster, the scales on the scutellum paler. Abdomen depressed, 

 truncate at tip, dark-scaled above with distinct coppery luster, the 

 anterior angles of the segments laterally silvery white-scaled ; be- 

 neath with basal segmental silvery bands. Wing-scales dark brown- 

 ish, long and narrow. Legs bronzy brown, the apices of the hind 

 tibise and the bases of the first, second, and third tarsal joints very 

 narrowly pale-marked ; claws simple. Length, 3 mm. 



Male. — Palpi longer than the proboscis, entirely black-scaled ; 

 coloration as in the female. Length, 2.5 mm. 



. Tv/o specimens, Coscojar River, Porto Bello Bay, Panama (A. H. 

 Jennings). 



Type no. 12051, U. S. N. M. 



CULEX IMITATOR Theobald 



The typical adult has the thorax adorned with silvery markings, 

 but these may be absent. We would restrict our name vector, based 

 upon larvae, to this form in which the silvery markings are absent. 



CULEX VINDICATOR, new species 



The name Cule.v inquisitor D. and K. is here restricted to the 

 Trinidad specimens. We propose the new name Culex vindicator for 

 part of the specimens from Dominica included under inquisitor 

 (Journ. New York Ent. Soc, xiv, 211, 1906). In the Dominican 

 species the proboscis is not ringed, the tarsal joints are narrowly 

 marked with white at both ends, except that the tip of the last hind 

 tarsal joint is black, the abdomen with basal white segmental bands. 



Four specimens, Dominica, July (A. Busck). 



Type no. 12098, U. S. N. M. 



The larvae are similar to those of inquisitor, but the basal tuft of 

 the tube is without the pecten. 



CULEX DICTATOR, new species 



Another part of the specimens referred to above from Dominica 

 are close to vindicator, but the abdomen is differently colored ; in 

 the present species it is black above with a coppery luster, the basal
