SUBFAMILY DEINOCERITIN^. 



19. Chitin of head produced laterally into a promi- 



nent angle caudad of, and extending laterad 

 of, the base of the antennae. Head at least 

 twice as long as thorax Democerites. 



SUBFAMILY URANOT^NIN^. 



Chitin of head never produced laterally, with 

 four large, stout spines in place of tufts A and 

 B, antennal tuft represented by a single hair. 



Uranotcenia.

20. Without a conspicuous spine at posterior angle 



of thorax. 1 Wyeomia. 



Key to Species of Larvae. 2 



1. Breathing tube almost wanting, not tubelike. 



Palmate tufts on some of abdominal seg- 

 ments three to seven. Long thoracic tufts 

 reduced to slender, long-plumose hairs. ... 2 

 Breathing tube well developed, tubelike. Long 

 thoracic tufts present, or represented by stiff 

 spines with spinules. No palmate tufts. ... 6 



2. Plumose lateral hairs on abdominal segments 



four to six. Spines of comb subequal. Hairs 

 on cephalic margin of head simple. Hair near- 

 est meson of dorsum in the first thoracic row 

 well developed, slightly plumose. Spines of 

 palmate tufts uniformly pale. 



Anopheles barberi. 



1 This character was given it by me in more extended tables n- 

 cluding extralimital forms, and separates this genus from that of 

 Dendromyia , which possesses a stout, heavily chitinised spine at the 

 posterior angle of the thorax.
