42 THE CANADIAN ENTOMOLOGIST. 



or also confluent with the lateral blue-gray area, but always leaving a row 

 of black patches, one in the middle of each segment. A faint, lateral, 

 pale orange or whitish line, broken and bordering the black patches 

 below. Below this line to the legs, blue-gray, mottled with black, with 

 traces of a whitish substigmatal line and one along the bases of the legs. 

 Venter black, immaculate. Thoracic feet black, the abdominal ones 

 pinkish at tips. Hair moderately abundant, faintly reddish tinged on the 

 back, white on the sides, but rather thin and not tufted. 



Food-plants. — Wild gooseberry (Ribes) and rose (Rosa.) 



Habitat. — Nevada, Montana, Wyoming, Colorado, and probably all the 

 arid region from the eastern slope of the Rockies to the Sierra Nevada 

 and Cascade Mountains. 

 Clisiocampa pluvialis, nov. sp. 



1883 — Stretch, Papilio, iii , 20 (as larva No. 1). 



Larva. — Head hairy, bluish-gray, spotted with black, the spots segre- 

 gating on the vertex, or covering nearly the whole head ; labrum and 

 bases of antennae yellowish white. Body black, a pale blue dorsal line, 

 divided between the segments, obsolete at the extremities, and forming 9 

 rather narrow, elongate, blue spots tapering at their ends, exactly as in 

 C. fragilis. A subdorsal row of blue dots, two on each segment, the 

 anterior one the smaller, and not reaching quite so far down. Between 

 these is an orange band, starting in a small spot on the anterior part of 

 each segment and either broken or connected with a broad triangular 

 widening of the band on the posterior part. A distinct, broad, but rather 

 irregular, pale orange, lateral band, narrowly broken here and there, and 

 containing a few black dots. Below this, a slight suffusion of blue, mot- 

 tled with black, and a diffuse and mottled pale orange substigmatal band, 

 besides another along the bases of the legs. Below, black, with a double 

 diffuse and mottled bluish band, or the venter all mottled with bluish 

 white. The subdorsal orange band is very conspicuous, It may extend 

 from near the dorsal line to below and behind the subdorsal blue spots 

 and also in front of them, but is usually less on the anterior part of the 

 segments and always retracted centrally. Its dorsal edge is well defined, 

 a little curved on each segment, following the outline of the pieces of the 

 dorsal band, but always separated from them by a black space, though it 

 sometimes nearly surrounds them by connecting over the dorsum with the 

 band on the other side, posteriorly on the segments. In some examples 

 the region below the subdorsal band to the venter is largely overspread
