running into the yellow part of the protboraeic segment, and confluent posteriorly on the tenth 

 abdominal, which is all yellow except the anal plate and a dorsal band. The three upper lateral 

 lines are connected also on the eighth and ninth abdominal segments by a broad, dark yellow 

 shade. The bases of the legs and corresponding spots on the apodous segments (on the tirst, 

 second, and seventh, eighth, and ninth abdominal segments) also dark yellow, forming expansions 

 of the subventral line and reaching the lowest lateral line, except on the thoracic segments and 

 the ninth abdominal. On the apodous segments in the center of each yellow patch is a snmll, 

 lilack spot, representing the absent legs, but thLs is not ])resent in all exanqdes. Hair rather 

 abundant, sordid white, the long and short hairs concolorous, arising from minute blackish 

 tubercles which, in the black parts of the body, are each surrounded by a minute yellow ring." 



''■Pupa. — Exactly like that of I>. mnjor; the two cremasters each bear three spines in a 

 transverse row, the posterior one the longest. Length, 28 mm.; width, 10 mm. 



" Single brooded, the winter being passed in the pupa state beneath the ground. The 

 duration of the larval stages was as follows: First stage, five days; second stage, six days; third 

 •stage, six days; fourth stage, seven days; fifth stage, seven days.

The belated larva^ of what I regard as I), drexelii (PL XI, fig. 2) occuiTed on the sassafras 

 tit Providence, E. I., October 3, and are described as follows : 



Length, 20 mm., head black, body pale yellow ocher, prothoracic segment yellow; cervical 

 plate transversely oblong, shining brown-black. Dorsal and subdorsal region of the body of a 

 peculiar pale reddish vandyke brown, inclosing eight lines which are lemon-yellow, thus slightly 

 differing in hue from the body beneath and on the sides. The dorsal and first or upper subdorsal 

 lines somewhat wider than the two lines beneath, and the lowest or fourth (infraspiracular) line is 

 waved and twice as wide as those above. Spiracles minute, black, situated in the pale reddish 

 brown band above the fourth or lateral yellowish line. The ninth abdominal segment pale 

 yellow ocher, the lines ending in this area, though not blending with each other before reaching 

 the ninth segment. A ventral lemoii yellow meilian line, with a broad, ])ale reddish l)rown band 

 on each side. Thoracic legs Ijlack; the four pairs of middle abdominal legs externally tipped 

 with black; anal legs slender, black. Suranal plate small, transversely oval, its surface shining 

 black, with irregularly scattered punctures and piliferous depressions rather than warts, from 

 which about twenty black and a few gray hairs arise. Tlie hairs on the body are few and 

 scattered, and no longer than the body is thick; they are uneven in length and pale in color.
