INSECUTOR INSCITI^ MENSTRUUS 29 



pools in said gut are continuously supplied with water from a 

 well on the hill-side. These pools contain algae. The larvae 

 of D-1 were caught on October 26, 1919, and the adults 

 emerged on November 1, 1919." 



Larvae from Leinster Bay, from which typical petersoni 

 were bred, although not isolated, are as follows : 



Head rounded, flat, about as broad as long; antennae mod- 

 erate, a large tuft at the outer fourth, the part beyond it 

 slender; head-hairs fine and pale, in tufts of about four each. 

 Lateral comb of the eighth segment a patch of about 30 small 

 remote spines with narrowly expanded feathered tips. Air- 

 tube about five times as long as wide, thick and nearly uni- 

 form, finely pilose, especially toward tip ; pecten of about ten 

 teeth, the outer ones widely separated, and reaching beyond 

 the basal third of the tube ; eight large hair-tufts along the 

 posterior margin of the tube, the basal one well within the 

 pecten and the second nearly so, the last one being subapical ; 

 tracheae in the tube broad and straight. Anal segment slender, 

 with a small dorsal chitinous saddle. Anal gills only two, 

 short, sac-like, firm and yellowish.

 Culex (Transculicia) eleuihera Dyar, Ins. Ins. Mens., vi, 100, 1918. 



From the close similarity of the larva of petersoni, just 

 described, with Culex bahamensis D. & K., hitherto known 

 only as larva, it is evident that eleuthera Dyar is the adult of 

 bahamensis larva, and that the above synonymy will obtain.
