abdominal^ ^yhicll is all yellow except the anal ])late and a dorsal band. The three ui)])er 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 spots on the apodous segments (on the iirst, 
second, and seventh, eighth, and ninth abdonnnal 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 small, 
black spot, representing the absent legs, but this is not present in all examjdes. Hair rather 
abundant, sordid white, the long and short hairs concolorous, arising from minute blackish 
tubercles which, in the black parts of the body, arc each surrounded by a minute yellow ring.”

The belated larvm of what I regard as J). drcxeUi (PI. XI, fig. 2) occurred on the sassafras 
at Providence, E. I., October 3, and are described as follows: 
Length, 2G 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 
diflering 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 htwcst or fourth (infrasi)iracular) line is 
waved and twice as wide as- those above. Spiracles minute, black, siUiated 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 this area, though not blending with each other before reaching 
the ninth segment. A ventral lemon-yellow median line, with a broad, pale reddish brown band 
on each side. Thoracic legs black; the four i^airs of middle abdominal legs externally tipped 
with black; anal legs slender, black. Siiranal 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. The hairs on the bod}" are lew and 
scattered, and no longer than the body is thick; they are uneven in length and i)a]e in color,
