process, the first longest; a spine before, a small tooth and a large trifid one at 

 base, a long serrate filament and row of feathered hairs within ; process below 

 obscurely furcate, with a transverse and a longitudinal row of hairs and a tuft 

 at tip of each limb ; basal angle small, a row of hairs within enlarged dentate 

 bases ; a row of long hairs at base. Maxilla elongate, conical at tip, divided by 

 a suture ; a row of spines on margin of inner half and two rows of cilia ; a row 

 of long hairs at tip running down along the suture ; outer half with two filaments 

 below middle and a spine on other side. Palpus small, with four minute apical 

 digits. Thorax rounded, wider than long. Abdomen moderate, anterior seg- 

 ments shorter ; lateral hairs multiple on first segment, triple on second, double 

 on third to sixth ; subdorsal hairs in threes on third to seventh segments ; skin 

 pilose. Air-tube very long and slender, gradually tapering, eight times as long 

 as wide; pecten not reaching basal third, its teeth broad, with four or five 

 branches ; four tufts beyond pecten, the subapical one moved laterally out of line. 

 Lateral comb of eighth segment of many spines in a triangular patch; single 

 spine elongate, widened at tip, fringed with spinules. Anal segment longer than 

 wide, ringed by the plate ; dorsal tuft a group of long hairs on each side ; a single 

 lateral hair; ventral brush well developed, confined to the barred area. 



The larvae live in ground-pools. Mr. Busck found them in a pot-hole near 

 the coast, where there were many holes and caves.

 GBiorNAL Description of Ciilex vindicatob: 



The name Culex 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 (Joum. New York Ent. Soc, xlv, 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 with- 

 out the pecten.

Female. — Proboscis moderate, subcylindrical, uniform, labellae conically 

 tapered; vestiture brown, with bronzy luster; setae minute, curved, black, those 

 on labellae more prominently outstanding. Palpi small, slender, one-fifth as 

 long as proboscis, black, with a few outstanding setae. Antennae with the basal 

 joints somewhat shorter, rugose, pilose, black, the second joint slightly enlarged ;

 brown ones, eyes with a border of white scales expanding below; a row of black 

 bristles along margins of eyes. 



Prothoracic lobes elliptical, remote dorsally, clothed with brown setae. Meso- 

 notum brown with two dorsal impressed concolorous lines showing very faintly 

 on anterior half; vestiture of narrow, curved golden-brown scales, paler around 

 ante-scutellar space; bristles coarse, brown, numerous. Scutellum trilobate,
