SOUTH AMERICAN EUMOLPIDA. 29 
Type, 2, Bartica Dist., Br. Guiana (Coll. 406) kindly presented 
to me by the New York Zoological Park Bureau of Tropical 
Research. 
Length, 9°5 mm. 
Head grossly punctate with a deep frontal fovea ; thorax wider 
than long, grossly confluently punctured, with a few smooth 
areas on the disc, obsoletely depressed on either side behind the 
middle ; scutel with one or two large punctures ; the elytral area 
around the scutellum is depressed, and the thick punctuation 
gives a semi-opaque appearance. 
This form is so large and comes from such a comparatively 
well-worked district that Iam rather surprised not to find any 
description fitting it. 
Colaspis goyazensis, sp. NOV. 
Like trivialis, Boh.; oblong. Above and beneath greenish bronze, 
with apex of elytra paler; legs pale, with knees, apex of tibize and 
tarsi cyanescent; antennze long and _ slender, rufous, becoming 
fuscous after the middle; palpi and labrum rufous, thorax unidentate 
at about the middle; upper surface thickly punctate, the elytra mostly 
in double series with smooth, more or less raised longitudinal 
intervals which become costate at the apex. Hind tibia of ¢ nearly 
simple, very feebly sinuate. 
Type, 4 g and 1 9, Mineiro, Goyaz, Brazil. 
Length, 5-5-6 mm. 
Head closely punctate, moderately longitudinally impressed 
on the front with the usual smooth calli; thorax thickly coarsely 
punctate ; sides angulate at the middle and sinuate before; the 
punctuation of the elytra is more or less confused near the scutel 
in the 2. Allied to and resembling trivialis, Boh., but easily 
separated by the very different hind tibia of ¢. The general 
appearance is bronzy-green with apex of elytra pale. 
Colaspis dilatipes, sp. nov. 
Like a large trzvialis, Boh.; elongate. Shining, bronzy brown; 
legs and antennz more or less rufous; head finely, thorax coarsely, 
thickly punctate; sides strongly angulate at middle, ¢ with median 
smooth line; elytra regularly biseriate punctate, with raised longi- 
tudinal smooth intervals, which are costate at the rear; hind tibia 
of ¢ strongly dilated below the middle, forming a blunt bulge 
within. 
Type, g¢ and 9, Ceara-Mirim, Rio Grande de Norte, Brazil 
(W. M. Mann). 
Length, 7-7-5 mm. 
Head densely punctate, faintly longitudinally sulcate, with 
prominent smooth calli; antenne dark, with the bases of the 
joints light, thorax widely margined and prominently angled at 
the sides and with a post-median depression on each side (more
