Obiginai. Descbiption of Cuiex absobbinus : 



Larvse, first referred to Culex consobrinus Desv., were taken in a cold moun- 

 tain pool at Mizabethtown, N. T., July 8, where they were found in small numbers. 

 A few adults were captured in the same locality the latter part of August. 



Female. Proboscis about as long as the abdomen, dark brown; palpi light brown, 

 rather sparsely clothed with yellowish white scales. Antennse black, sparsely 

 clothed with short, brown hairs and with several long, black ones at bases of joints. 

 Byes coarsely granulate, greenish. Occiput sparsely clothed by and margined an- 

 teriorly with white scales, and with a thick tuft of the same at the juncture of the 

 eyes; numerous erect, scattering, black scales occur among the yellowish white ones. 

 Thorax brown, clothed with a fine, appressed pile; a median line of dark brown or 

 black scales, golden yellow anteriorly and terminating at the posterior third in an 

 irregular, rather loose group of golden yellow hairs; a submedian line of golden 

 yellow hairs bordered internally with long, black ones and extending anteriorly into 

 a somewhat irregular patch. Anterior margin of thorax with golden and yellowish 

 white scales, the lateral margin bordered by long, blackish hairs, and internally 

 with a few yellowish white scales. Scutellum brownish, clothed apically with a row 

 of long, brownish hairs and with a pair of submedian patches of whitish scales an-

 and that of the second over %. Fringes and scales clothing the veins mostly dark 

 fuscous, thick, scales very long, narrow. Fringe composed of scales of several 

 lengths as in the pipiens group. Halteres capitate, stem and base yellowish, tip

 palpus. Antennae rather sparsely ornamented with brownish plumes, brown, each 

 segment annulate with white. Eyes rather coarsely granulate, greenish black.

 on posterior border of the eyes, a sparse median tuft at their juncture, and also have 

 a somewhat linear arrangement each side of the median line; erect black forked
