teriorly and a median pair of teeth, A pair of bristles arises 

 on the dorsum of each of the body divisions two to eleven 

 inclusive, each bristle originating in a black dot. Posterior 

 somite black centrally. Skin everywhere roughened with 

 small granulations. 



Apparently gregarious. Pupas were taken with the 

 larvae, and still retained the cast larval skin about the pos- 

 terior part of the body. 



CULICID/t (MOSQUITOES). 



Members of this family are present in the mountains, 

 but appear to attract less attention than they do in more 

 level countries in which are more ponds and sluggish 

 streams. Some larvae commonly known as wrigglers are to 

 be found there in barrels of water and in ditches and pools 

 of various sorts. They were about gone from their usual 

 haunts, however, and I saw less of them at Pineville than I 

 probably should earlier in the season. The streams them- 

 selves because of their rapid current are not well suited to 

 the requirements of mosquitoes. People with whom I con- 

 versed reported some mosquitoes as giving trouble during the 

 hot summer months. I found confirmation of their state- 

 ments in an engorged adult of Anopheles punctipennis in my 

 room in Pineville. My attention was of necessity concen- 

 trated on the genus Simulium, and I learned less of the 

 mosquitoes as a consequence than I otherwise should. More 

 attention will be given to them later.
