bright, transverse, deep-orange, irregular band in the sutures between the 

 second and third thoracic and the third thoracic and first abdominal seg- 

 ments. In the middle of each band is a black dot situated in the median 

 line of the body. When the larva is at rest and the segments contracted, 

 these two conspicuous stripes are not visible. They are evidently 

 warning or danger signals.like the showy, bright band of Gastropacha 

 americana. 



The anterior corners of the protlioracic segment are dull orange-brown, 

 the segment itself being dull dark brown, with no lines. The median 

 dorsal rather bright tawny-brown stripe begins most distinctly on the 

 first abdominal segment, and extends uninterruptedly to the base of the 

 suranal plate. The subdorsal lines, one on each side, are brighter ochre- 

 ous orange, but are broken up, not only at the sutures, but by the trans- 

 verse wrinkles, of which there are usually about five to each abdominal 

 segment. The subdorsal lines or stripes are interrupted at the hinder end 

 of each segment, next to the suture, by an irregular, squarish, light, 

 tawny, ash patch, those on abdominal segments 7 and 8 being much 

 paler and more distinct than the others in front. 



The lateral supraspiracular line is narrower than the subdorsal stripe, 

 less ochreous, with a little more pale yellow in it ; it is irregular and 

 broken, contains short, wavy, blackish lines and isolated dots, and dilates 

 a little at the hinder end of each segment, forming a linear, light, pale, 

 obscure yellowish spot opposite the light spots in the subdorsal stripe. 

 Spiracles distinct, dull carneous, surrounded by a blackish-brown ring. 

 An infraspiracular indistinct, wavy, narrow, tawny-yellowish, much- 

 broken line, most distinct under the spiracles. Still below this obscure 

 line the lateral ridge, which is quite broken, is marked with two obscure 

 tawny reddish, vertical slashes on each segment; one is single, and the 

 other is slightly V-shaped, the apex pointing upwards. The suranal plate 

 is ornamented in front by the end of the dorsal tawny or Scotch-snuff 

 brown band, broadly edged with ochreous yellow, the rest of the plate 

 being black-brown. 



The anal legs are dark-brown, with no markings ; the middle abdomi- 

 nal legs are spread out laterally a good deal, so as to show from al)Ove 

 almost their whole length ; the legs themselves are, at base, livid lilac- 

 brown, the plantai pale livid, with a black chitinous streak on each side ; 

 these peculiar black chitinous pieces are narrow triangular, with the 

 slender very acute apex pointing upwards, and are distinctly visible from 

 above. The dense hairs arise from the longitudinal folds of skin situated 

 over the abdominal and thoracic legs and corresponding situations on the 

 other segments.
