a little less than one-half of an inch. The antennae are long, slender 
and dark brown with numerous fine white annulations. The palpi 
are moderately prominent and mottled with yellowish and dark 
brown scales. The head is mostly purplish brown shading to yellowish 
brown above the mouth. The thorax is thickly covered with dark 
brown scales with a variable mottling of yellowish brown, the abdo- 
men being a little darker. There is in well-marked specimens near 
the base of the forewing a rather broad, broken, angulate darker 
band near the basal third and a less distinct and more regular but 
somewhat broken dark band near the distal fifth, an area between 
this and the basal third being a variable grayish with one or more 
dark spots near the costal margin. The hind wings are dark fuscous 
and both fore and hind wings are margined with rich purplish brown 
scales. 
Pupa (figure 4). Length about one-fourth of an inch, moderately 
stout and dark bronzy yellow, var atly marked w'th fuscous, espe 
cially on the posterior abdominal segments. 
‘Lhe head is dark brown with a few fine, 
moderately long hairs. Antennal cases 
slender, the variably yellow mottled wing 
cases extending to the sixth abdominal seg- 
ment, the leg cases reaching just a little 
beyond. The mouth-parts and most of the 
median ventral area between the antennal 
cases yellowish. The dorsum of the thorax 
dark bronzy yellow. Scutellum fuscous yel- 
lowish and with a very fine short pubescence. Dorsum of the 
abdominal segments moderately smooth, shiny, the segments when 
flexed ventrally showing along the anterior margin series of minute 
closely set teeth. Terminal segment yellow.sh.
