SOUTH AMERICAN EUMOLPIDA. 27 
C. chalcites, Lef., from Peru is described by Lefevre without 
mentioning any details of the 3, and my three examples, which 
apparently came from Lefevre, are all @’s. A form occurs in 
Bolivia which might be this or a closely allied species. The 
Bolivia ¢ form has a well-marked notch on the inside of the 
hind tibia at about the beginning of the apical third ; until it is 
compared with a 3 of chalcites I prefer to call them all alike, 
though they differ somewhat in other details. 
Colaspis geminata, Let. 
The four specimens I give this name to are from Rio and 
Teresopolis, and all are ? ; chestnut brown with zneous colour- 
ing; geminata, Boh., I identify in a ¢ from Rio, dark bronze 
colour ; it is larger than the foregoing 2s, thorax not so heavily 
punctured and elytra more regularly geminate punctate, and 
with the hind tibize strongly dilated within. For the present I 
regard the forms as distinct, but if they should prove the same 
Lefevre’s name must sink as a synonym; plenty of specimens 
from Rio would settle the question. 
The types of all the forms hereinafter described are in my 
collection. 
Colaspsis townsendi, sp. nov. 
Form and size of prasina, Lef. Body above and below entirely 
dark purple ; legs, palpi, labrum and antennz flavous, the latter with 
the last five or six joints dark; thorax grossly confluently punctate, 
elytra grossly punctured, largely in double series, the intervals more 
or less raise d,g iving a semicostate appearance as in prasina, Lef. ; 
hind tibia of ¢ sinuate or feebly dilated within. 
Type, ¢ and 9, Jicaltepec, Vera Cruz, Mex. (Townsend). 
Length, 7-8 mm. 
Head densely and coarsely punctate (except the vertex) with 
smooth calli near the eye, more or less longitudinally impressed 
on the vertex ; thorax unidentate at the side and sinuate just in 
advance of the angle, so that it might be called subbidentate ; 
scutel and umbone of the elytra smooth, the latter without 
visible depression, and crowded with gross punctures which are 
confused in the neighbourhood of the scutel—heretofore classed 
in collections as prasina, Lef., but separable by the sinuation of 
the ¢ tibia; it is also apparently a more northern form; the 
2 is somewhat larger than the 3, tibia plain, last ventral 
segment with heavy punctures and bluatly notched. 
Colaspis lebasoides, sp. nov. 
Form of a small prasina, Lef.; oblong. Metallic green above and 
below ; feet, palpi, labrum and antenne flavous, the latter somewhat 
infuscate at tip; head everywhere densely punctate with usual
