[These differences of larvae and pupae may be thrown, for con- 
lence, into a table as follows: 
vi 
SYNOPSIS OF LARViE. 
Mandibles bifid at tip. 
a. Inner edge of mandibles excavated before tip, anal seg¬ 
ments shorter than preceding, ventral tubercles not orom- 
ment - Paria. 
b. Inner edge of mandibles not excavated, anal segments more 
developed than preceding, ventral tubercles prominent 
with long hairs. Colaspis. ’ 
# 
Mandibles entire at tip, inner edge excavated, anal segment short 
ventral tubercles not prominent. Scelodonta. 
SYNOPSIS OF PUPJE. 
s 
Amal hooks simple, incurved. 
Colaspis . 
A.nal hooks recurved. 
a • Hooks short and stout with strong erect tooth at upper 
side of base and two long hairs on posterior margin.— 
Scelodonta. 
b. Hooks slighter, simple, or with slender hair at upper side 
of base, no hairs on margin. n -~- 
Paria. 
e beetles may be very easily distinguished, the Colaspis being 
Uy °f a pale clay-yellow, ranging to a yellowish brown, smooth 
lot shining, concolorous throughout, or occasionally with the 
and thorax green; while Paria is shining black above, varying 
own with four black blotches upon the wing covers, but always 
pale legs; and Scelodonta is purple or green, with a bronzed 
llic lustre, and covered with a gray pubescence, of which both 
ther species are destitute. 
'ropose now to give the literature, descriptions and life histories 
ich of the species separately, as far as is necessary for the 
nt purpose, and afterwards to treat of the injuries to vegetation 
)f measures for the control of all three of the species together.
