Dec, 1906] Dyar and Knab : Larv^ of Culicid^. 221 



on third to fifth, single and long on the sixth. Air tube 9x1, wide 

 at base, the pecten sparse and long, reaching to one-fourth, followed 

 by a little double-haired tuft. Lateral comb of the eighth segment 

 a large patch of long spines. Anal gills moderate, pointed. 



Collected by Mr. Urich in Trinidad from Bromelia water. It was 

 named by Mr. Coquillett "Culex van' palpus Coq.,' ' but on our remon- 

 strating with him, it was changed to "Culex imitator Theob.'' We 

 cannot adopt this name, either. (See remark under the preceding 

 species). 



Culex rejector, new species. Fig. 54. 



Antennae with the tuft near the outer third, pale; head hairs, the 

 upper tuft multiple, the lower single; body glabrous; lateral hairs in 

 twos on segments 2 to 5, single on the sixth; tracheal tubes narrow, 

 angled. Air tube very long, 10 x 1, nearly straight, with four small 

 tufts on posterior margin; pecten of very long spines to one-fifth. 

 Lateral comb of the eighth segment of long spine-like scales. Later- 

 al tuft of the anal segment very large; gills long and pointed. 



Collected by the junior author in a large Bromeliaceous plant at 

 Cordoba, Mexico, with C. gravitator. All these larvae died, presum- 

 ably from lack of their natural food. 



Culex inimitabilis, new species. Fig. 55. 



Collected in Bromelia water by Mr. Urich in Trinidad with C. daum- 

 asturus, which it resembles, but lacks the swelling on the tube. The 

 body is smooth; the lateral hairs are in threes on the first segment, 

 twos on the second, threes and short on the third to fifth, twos and 

 long on the sixth. It was named "Culex? pipiens L ,'' by Mr. Co- 

 quillett; rather a worse guess than usual. 



Culex conservator, new species. Fig. 56. 



Antennae with the tuft beyond the outer third, dark ; air tube 8x1, 

 a single hair at the middle; pecten not reaching one-third. Anal 

 segment long with short gills. 



Collected by Mr. Busck in a hollow tree in the village of St. Joseph, 

 Trinidad. Also in hollow trees near Montserrat, Trinidad, and Fort 

 de France, Martinique, but these are broken and we do not feel sure 

 of them. All were labelled " A'edes perturbans Will." by Mr. Coqu-
