length of the body, slightly incrassate at tip; thorax broader 
than long, a well-marked fovea on each side, next the margin, 
the punctuation sparse and fine except around the fovea; elytra 
with well-marked shoulder knobs and transverse and post-scutellar 
depressions, somewhat interrupting the coste, which, beginning 
with those next the suture, gradually tone down into smooth 
interspaces, having the punctures arranged in more or less 
geminate rows, especially on the rear disc. 
The square prominent elytral base and shoulders give this 
form the appearance of a species of Otilea like fulva, Jac. 
Colaspis brunneipennis, sp. nov. 
Rather large and stout. Body below bluish black, above with 
head, thorax and scutellum eneous black ; elytra chocolate brown, 
both thorax and elytra very narrowly margined with metallic 
cyaneus ; feet, antenne, labrum and palpi testaceous. 
Types, three 2, Balzabampa, Eeuad, (Haensch). 
Length, 6-8 mm. 
Head thickly punctate with both transverse and longitudinal 
grooves and smooth antennal calli; antenne about half the length 
of the body, partly fuscous in some examples; thorax strongly 
transverse, subbidentate on the sides, or unindentate with a 
sinuation in front; surface grossly and confluently punctate and 
deeply foveate on each side, just back of the middle; elytra with 
a very obsolete basal depression, grossly confluently and sub- 
geminately punctate, with the intervals semicostate or costate at 
the sides and apex, easily recognised by its colour ; ¢ is unknown. 
Colaspis peruvianus, sp. Nov. 
Short, stout, ovate, shining. Above purplish zneous, below with 
legs cyaneous green or blue; head thickly punctate, faintly im- 
pressed; thorax coarsely punctate, sparsely so on the disc, sides 
strongly angulate at the middle; elytra grossly foveate punctate, 
semi-serlately arranged, and transversely confluent in places; the 
longitudinal intervals costulate near the apex and sides; inside of 
hind tibia of ¢ with a minute spine at apical third. 
Type g and 9, Peru (Callanga ?) (second Jac. Coll.). 
Length, 4 mm. 
The punctuation of the thorax is much coarser than in 
chalcites, the elytra more convex and the punctures much more 
foveate. It is nearly related to melancholica, Jac., from Mexico. 
This latter, as well as nigrocyanea, Cr., both have notched or 
spined ¢ tibia. 
Colaspis 4-foveata, sp. nov. 
Size of subenea, Jac. Body below cyaneous black, above 
geneous bronze with a faint greenish tint; thorax wide, strongly
