not in line, the posterior one being at the back of the seo^n^.ent, and 

 higher up; all the hairs bent down; head rounded, depressed a little at 

 the top, the vertices rounded; color dark brown, smooth, with a few 

 black hairs curved down. Duration of the stage about eight days. 



After first Moult: slender, cylindrical; color dark brown, a medio- 

 dorsal stripe, greenish yellow ; there are seven principal rows of spines, 

 one dorsal, three on either side, disposed as hereinafter described for 

 mature larva; all but the dorsals black, these are the color of the band 

 or stripe they stand on, greenish yellow; the spines are long, slender, 

 tapering, with divergent black bristles placed at a small angle; along 

 base a row of minute spines; 2 has a chitinous cross-band, with several 

 fine points, each with a long black hair; head ob-ovoid, truncated at 

 top and depressed, the \'ertices rounded; color black, shining, thickly 

 beset with long black hairs which hang over the front. Duration of 

 this stage nine days. 



After second Moult: length .24 inch; very much as in preceding 

 stage; the dorsum and upper part of side brown-black, the lower part 

 of side brown-gray; the dorsal spines and bases green-yellow, and a 

 little of same color at base of second laterals on the outer side; head 

 as before. Duration of this stage twelve days. 



After third Moult: length .33 inch; color black; along dorsum a 

 whitish band, or double stripe, the intervening space making a black 

 medio-dorsal line; the whole surface of upper side thinly dotted with 

 white points, each of which gives a long white hair; the dorsal spines 

 black from orange bases; the first laterals black from shining black 

 bases; the second laterals black, but on the lower side at base is an 

 orange patch encircling the spine, except on the dorsal side; the third 

 laterals orange, from bases of same color, on 2 and 3, the rest black 

 with a little orange on upper side; the row over feet all orange; head 

 ob-ovoid, flattened frontally, deeply bilobed, the vertices rather high, 

 sub-conic, the face rough with tubercles of various sizes, each giving a 

 long black hair. Duration of this stage eleven days. 



After fourth Moult: length .45 inch; closely like previous stage; 

 there is a great difference in the last two stages in the clothing of body, 

 some larvae having a few white points, and corresponding white hairs, 

 but the greater number have these points thickly sprinkled over whole 

 upper side, and the numerous long hairs from them gi\e a very woolly 

 covering. Duration of this stage nine days. 



After fifth Moult: length .7 inch; at about eight days is fully grown. 



Mature Larva. — Length i.i inch; greatest breadth .2 inch; cyl- 

 indrical, of even size to near the extremities; color black over upper 

 part of side and dorsum, lower part of side brown-black; along dor- 

 sum a double whitish stripe, and a macular whitish stripe in line with 

 second lateral spines; whole surface covered with white tuberculous 

 ])oints, of varying sizes; these are sometimes comjjaratively few in num-
