and rather large. The two median tubercles are minute, and the 

 two subdorsal ones large. The two rows of small dorsal tubercles one- 

 haired; those of the subdorsal row (or 3d row from below of the abdomi- 

 nal segments with legs) bearing each two hairs; the second dorsal row of 

 2d and 3d thoracic segments bearing each two hairs, but the next row 

 beneath with one on the segments provided with legs. Hairs nearly 

 twice as long as the body is thick; the dorsal hairs black and the lateral 

 ones grayish. Thoracic legs dark amber brown. Abdominal legs 

 amber, with an external dark piece. A distinct subcrescentiform dark 

 conspicuous prothoracic plate. It molted July 7-8. 



Stage II. — Length 6 mm. Head black. Dorsal tubercles black, 

 with from ten to twelve black spinulated hairs. A dorsal median row 

 of whitish spots beginning on the second thoracic segment, and a similar 

 subdorsal line. The lateral tubercles dusky amber colored. The gen- 

 eral hue of the skin dark amber. Prothoracic plate not very large, with 

 dark dorsal tubercles. It molted July 10. 



Stage III. — Length 7 mm. Head black, shining, not so wide as 

 the body. The body now uniformly, with all the tubercles, shining 

 black. A conspicuous median dorsal white band, the spots separate in 

 stage II, being now smaller in proportion and connected, beginning as 

 before on the 2d thoracic segment. A faint dark livid subdorsal line, 

 at first not visible. About twelve spinulated pairs arise from the dorsal 

 tubercles, and, like those of the others are all black, except an occa- 

 sional small white one. It molted again July 17. 



Stage IV. — Length 10 mm. Much as before though thicker, the 

 body entirely black, with a whitish dorsal stripe ; no definite subdorsal 

 line, but the sides of the body between the tubercles are dull livid, the 

 livid band enclosing three rows of tubercles, i. <?., the 2d, 3d and 4th 

 from the dorso-median one. 



July 21, it was 15 mm. long, though it had apparently not molted. 



July 22, the pale subdorsal lateral band is whiter than before; this 

 band extends underneath around the body, enclosing four rows of 

 tubercles on each side, thus making a broad black band on each side of 

 the median dorsal line. It molted July 25. 



Stage V. — Length 15-16 mm. It is now deep black ; the dorsal 

 stripe now distinctly whitish yellow and narrow, with a broad black 

 band on each side. The sides of the body are darker livid than before, 

 the livid hue less apparent. The upper row of subdorsal tubercles are 

 pale, shining, glistening at the end, and black below. Thoracic legs 

 black; abdominal legs pale. It molted again July 31.
