NOLA CENTONALIS. 47 



tubercles (i. e. a transverse series of six across each 

 segment), the upper row the largest, the middle row 

 the smallest, and all emitting fascicles of radiating 

 hairs, single hairs of much greater length proceeding 

 from the anal tubercles, and one from each tubercle of 

 the lowermost row on the sides. The skin itself was 

 soft and smooth between these tubercles, which allowed 

 but little of it to be seen on the upper parts of the 

 body, but the ventral surface showed it to be soft and 

 just a trifle glistening ; the body tapered a little 

 behind, and rather more from second segment to the 

 head. 



It had only three pairs of ventral prolegs. 



The colour of the glossy head was blackish-brown, 

 above the mouth a broad streak of dingy pink, papillaB 

 paler; the body generally and the tubercles were of 

 this same dingy deep pink or dirty purplish pink, 

 beautifully relieved by a dorsal line of ochreous yellow, 

 which passed through a V mark of velvety-black at 

 the beginning of each segment, separating the black 

 into two sharp wedges. A fine linear black streak ante- 

 riorly ran beneath each upper tubercle, representative 

 of the subdorsal line ; the tracheal thread of faint pale 

 yellowish ran midway between the middle and lower 

 rows of tubercles, and showed more distinctly at each 

 part bearing a black spiracle directly on it, so that 

 this very faint yellowish line had an interrupted 

 appearance towards each segmental division. The 

 hairs were lightish greyish-brown, rather shining, and 

 from their reflecting the colour of the body and 

 of themselves also, and occupying so much space 

 about the upper surface of the body, produced 

 there somewhat of a general brownish effect. The 

 anterior legs dingy pink, marked with darkish 

 brown ; the ventral and anal prolegs of the pinkish 

 ground colour, but more transparent and fringed 

 with hooks. 



After feeding on flowers of common red clover for 

 several days it at length spun itself up after very
