segments ligliter; head anteriorly dark l)r()\vn, posteriorly the color 
of the body, mandibles darker than anterior ])orti(Mi of head. Cer- 
vical shield brownish yellow, anterior surface smooth polished, 
terminating posteriorly in a slightly raised transverse ridge. The 
apical declivity is shagreened, more finely posteriorly and centrally ; 
narrow median dorsal area whiter ; the lateral oblique, sinuate grooves 
darker. In front of the shagreened area are a few short erect hairs, 
with larger ones placed laterally on this segment. On the next seg- 
ment there are but two lateral hairs on each side, and none on other 
segments until the eleventh, which has a single stout bristle on each 
side considerably above the margin, and a transverse row of hairs 
along the posterior margin. The anal segment has a considerable 
number of long curxed hairs along the lateral and posterior areas. 
The lateral margins of each of the abdominal segments, just Itelow 
the spiracles, have an inflated appearance, and segments three to 
ten inclusixe are strongly sculptured, especialh' on the dorsal sur- 
face, by transverse, tubercular, flattened ridges which are minutely 
shagreened. The sculpture of these is clearly shown in Plate VIII.. 
Fig. c. The lateral inflations, with deep intervening constrictions, 
gi>'e the larva when extended a somewhat moniliform aspect. 
Pupa. — Length, 13 mm.; color uniformly light yellow; head 
with nearly triangular impressed area between the bases of the 
antennae, on each side of \vhich are a pair of closely set hairs. 
There are two clusters of minute spinules on the clypeus. The an- 
tennae, being aljruptly bent downward, gi\e the head a decidedly 
square appearance. They extend backward to just Ijeyond the mid- 
dle femora, where they turn forward along and outside of the an- 
terior and middle legs, the posterior pair of legs being folded undei 
the wings. There is a minute, robust, hooked spine on the marginal 
ridge of each of the abdominal segments excejjt the terminal, the 
hooks being reversed ; there is also on each of these segments a 
transverse dorsal elevation armed with irregularly placed minute 
stout spines. The terminal segment is provided with a number of 
long hairs.
