between the lateral and central ones. The pleura are blackish 

 with a few white scales collected into^ small patches. The femora 

 and tibiae are black with white scales, sparingly scattered over the 

 surface, their apices and base of the tibire in the posterior legs 

 white, the bases O'f the femora yellowish, especially on the under 

 side. The anterior and mid tarsi are black, usually without rings, 

 though the extreme apices of the joints and the base of the first 

 joints of the mid tarsi are pale and often distinctly yellowish. 

 The posterior tarsi are broadly banded' with pure white at both 

 ends of the joints, and the last one is wholly white. The claws 

 of the male anterior and mid tarsal joints (fig. yy, 4, 5) are 

 unecjual, the larger wnth a long blunt tooth one-third from the 

 base, the smaller with an extremely small acute tooth near the 

 base; the posterior claws (fig. 'jy, 6) equal and simple. The 

 female claws are equal and simple on all feet. The wing veins 

 are clothed with brown and white scales, giving the wing a gray- 

 ish appearance. On the radius and media, at their connection 

 with the cross vein, are white scales only, which together form a 

 distinct white spot; the scales on the basal half of the anal vein 

 are also white. 



The abdomen is brownish black with considerable variation in 

 the banding. There is always a large white spot, sometimes 

 divided transversely in two on the basal segment, which is con- 

 fined tO' the dorsal surface. The following- three segments have 

 narrow, ill defined basal bands which are often entirely obsolete; 

 the apical three segments have wider bands which become broad 

 laterally and join the side markings. Small patches of white 

 scales are sometimes near the apical margins of the penultimate 

 and antepenultimate segments. The venter is brown, with dif- 

 fused whitish bands at the base of the segments, the sides more 

 clearly marked wnth white joining the bands of the dorsum. 



Habits of the Adult. 



Practically nothing is known of the habits of the adult. It 

 has never been taken, indoors or out, by any of the collectors, 

 although they have collected in the localities where the larvae were 

 found. So far we have only bred adults out of larvae coming 

 from Delair, Camden County, and Chester, Morris County. The 

 larva only has been taken at Lahaway, Ocean County. 



The mosquito is a very pretty one when examined under a 

 magnifying glass, and by its narrow white lines on tlie thorax 

 recalls the yellow fever mosquito; indeed, it was at first placed in 

 the same genus — Stc^omyia. There is nothing about it tO' indi-
