PSYCHE 
[February 
set with acute infuscated tubercles from which issue moderate sized hair tufts 
and there are two very small tufts near the anterior margin. 
The abdominal segments are subequal, each bearing lateral hair tufts of from 
2 to 5 hairs each, the larger number on the anterior segments. The lateral 
patches of scales on the eighth segment are large, having from 25 to 30 scales in 
each patch. The individual scale is elongated, with a rather small .apical spine 
and smaller ones fringing the sides. The anal siphon is two and one half times, 
or slightly over, as long as broad, yellowish brown in color, thickest near the 
base and tapering a little apically. There are from 16 to 20 spines in each of 
the rows, the single spine with one or two teeth near the base. The ninth 
segment is almost square, nearly ringed by the chitinized saddle, and with the 
double dorsal tuft and ventral brush normal and moder.ate in size, the latter with 
several small tufts below the barred area. The tracheal gills are slender, about 
two and one half times the length of the ninth segment and taper to a point. 
Culex incnnspicuus Grossbeck. 
Larvte of this species were taken with C. sylvestris on the Garret Mts., near 
Paterson, N. J., Sept. 29, 1903. They began to die off in the breeding jar before 
it was known that we had a new larva to deal with. Then, only sylvestris were 
left alive but remnants in the bottom of the jar were placed in alcohol. In these 
remnants only the more strongly chitinized parts of the larvae remained, the anal 
siphon and the head case. The antennal attachments seem to offer but little 
resistance to decomposition: only one had retained them and these were in such 
condition as not to allow a description to be drawn. 
From the pupie in the jar, adult C. emerged as follows : i , 
Oct. 4; 1 ^ and i 9 , Oct. 5; and i $ , Oct. 6. 
The larva presents a general resemblance to C. sylvestris, but is much 
smaller. The mandibles and maxillary palpi are also similar to that species, but 
the sides of the mentum are more rounded and have fewer teeth, — 10 or 12 on 
each side of the apex. 'I'he hairs of the rotary mouth brushes are pectinated. 
The antenn.Te as well as could be seen were very much like those of C. sylvestris. 
The anal siphon is about three times as long as broad with 16 to 22 spines in 
each of the lateral rows; the individual spines are rather slender, and with one 
or two teeth near the middle, but in one larva the spines were stouter and had as 
many as four teeth on one spine. The lateral patches are large, each with about 
40 to 45 scales, the single scale with long slender apical spines and shorter lateral 
ones. The ninth segment is as broad as long, not quite ringed by the saddle and 
with the dorsal tuft and ventral brush moderate in size, the latter with small 
tufts below the barred area. None of the specimens retained the tracheal gills.
