Family CULICIDvE Stephens. 

 CULEX Linne". 



CULEX DAMNATORUM. 

 PI. 10, Fig. 14 9. 



None of the specimens referred here show much of the neuration of 

 the wings excepting parts of longitudinal veins, but the other character- 

 istics are unmistakable. The eyes are surrounded by a fringe of curved 

 lashes as long as the width of the eye. The antennae (all the specimens 

 are females) are fully as long as the thorax, slender, tapering, the joints 

 almost three times as long as broad, cylindrical, clothed sparsely with ex- 

 cessively short hairs, and showing signs here and there of a thin whorl of 

 fine hairs at the base of the joints a little longer than the joints themselves. 

 Palpi about as long as the head, more than twice as stout as the basal por- 

 tion of the antennae, the last joint almost obpyriform, bluntly terminated, 

 about three times as long as broad, and briefly hairy. Proboscis as stout 

 as the palpi, stouter than the fore tibiae, nearly or quite as long as the thorax. 

 Legs long and slender, clothed sparsely with fine short spinous hairs, and 

 the tibiae with inferior rows of more distant, longer, but still brief spines, 

 and the first joint of the tarsi with inferior rows of short, close set spines. 

 Hind tarsi nearly as long as the abdomen.

CULEX PROAVITUS. 



PI. 5, Figs. 8, 9. 

 Culex proaritim Scndd.. Bull. U. K. Geol. Geogr. Surv. Terr., Ill, 744 (1877). 



A poorly preserved specimen in which only fragments of the legs can 

 be seen, and the wings are so crumpled and folded as to prevent tracing the 

 neuration. What can be seen resembles the neuration of the Culicido>, and 

 the veins and borders are heavily fringed with long hairs. The body is
