running into tlu^ yellow part of tlie protlioraeic segment, and continent posteriorly on tlie tenth 

 abdominal, wliicli is all yellow except tlie anal plate and a dorsal band. The three njiper lateral 

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

 shade. The bases of the legs and corresponding si)ots on the apodous segments (on the tirst, 

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

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

 the junth abdominal. On the apodous segments in the center of each yellow ]>atch is a small, 

 black spot, representing the absent legs, but this is not present in all exaiiqdcs. Hair rather 

 abnudant, 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."

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

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

The belated larva? of what I regard as Z>. dre.velii (PI. XI, fig. 2) occurred on the sassafras 

 at Providence, R. I., October 3, and are described as follows: 



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

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

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

 differing iu hue from the body beneath and on the sides. The dorsal and tirst 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 i)ale 

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

 the ninth segment. A ventral lemon yellow median line, with a broad, i)ale reddish l)ro\vn band 

 on each side. Thoracic legs black; the four jiairs of middle abdominal legs externally tii)ped 

 with black; anal legs slender, black. Suranal plate small, transvei'sely oval, its sui'face shining 

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

 which about twenty black and a few gray hairs arise. The 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.
