vot. Iv.] Motes on Lepidopterous Larve. 357 
propriate time to publish the following description of the larva, 
which was drawn up some time ago. 
Larva.—Length (after being much contracted in alcohol), 20 
to 32 mm.; greatest width (7th and 8th segments), 7% to 10% 
mm. Black, naked except a few hairs on head and thoracic feet, 
head and thoracic segments corneous dorsally and variegated 
with whitish, rest of body fleshy. Three pairs of strong 3-jointed 
thoracic legs, each armed with a stout terminal claw; five pairs 
of prolegs, on segments 7 to 10 and 13. ‘The lateral plates of 
dorsa of segments are hardly whitish, or faintly so anteriorly in 
continuation of the whitish lateral line of thoracic segments. 
ere is also an inner lateral line on each side on each of 
the thoracic segments, and a median line on the prothoracic and 
mesothoracic only. The prolegs, with lateral portions of ventral 
surface, are also more or less whitish. Head is considerably nar- 
rowed, about half retracted within prothoracic segment. Anten- 
nz 3-jointed, first joint very stout and subconic with a truncate 
apex, about as long as basal diameter; second joint very short 
and retracted within the basal joint so that it is not conspicuous; 
third joint slender and subcylindrical, nearly as long as basal 
joint but not more than one-third its mean diameter, terminated 
by a bristle nearly three times its own length. Maxillary palpi 
4-jointed, basal 2 joints subequal, stout; third joint hardly as 
long and about one-half the diameter of second; fourth joint 
minute. Labial palpi slender, consisting of a basal elongate sub- 
cylindric joint terminated by a stout, pointed, bristle-like style 
about its own length, with a minute joint at its base. Spinneret 
elongate, slender, pointed. Labium with a deep notch on ante- 
rior margin, bristly. Mandibles very strong, strongly 4-toothed 
apically. Head is in younger specimens mostly whitish, only 
finely marked or speckled with blackish or brown. Prothoracic 
segment a little wider than head, fully or more than one-half as 
long as wide; mesothoracic segment wider than prothoracic but 
only one-half as long; metathoracic slightly wider than meso- 
thoracic, and about same length, as is also the fifth segment (first 
abdominal), which latter is a little wider than metathoracic. 
Segments 6 to 11 very gradually increasing in length, 11 being 
the longest; 12 a little shorter and narrower; 13 a little long
