192 THE ENTOMOLOGIST. 25 . 
narrowly edged with cyaneous ; labrum, anbenues and feet wholly 2 
rufous; the legs robust and short. 
Type, 1 g, Tucuman, a 
Length, 2°65 mm. 
Antenne reaching nearly the middle of the elytra; last five 
joints much thickened (like Nodonota) ; head thickly punctate, 
opaque ; thorax with anterior angles very prominent, sides 
strongly and sharply unidentate at the middle, scutellum 
smooth, elytra somewhat impressed within the shoulder, widen- ~ 
ing into a faint transverse depression, the surface very finely 
semi-seriate punctate, much plainer at the apex and sides, where 
the intervals are somewhat raised. 
Mr. Jacoby’s remarks referred to in my description of 
bidenticollis apply also to this species. 
Colaspis @neus, sp. nov. 
Very small; short, parallel. Above and below sneous bronze, 
shining; feet, antennze and mouth parts entirely fulvous ; head and 
thorax thinly, finely and evenly punctulate, sides strongly angulate 
at the middle; elytra finely semi-geminate punctate striate, costulate 
at the apex, the surface very finely alutaceous. 
Type, 1 ¢, Tucuman, Argentina (Baer). 
Length, 23 mm. 
Head with usual cross depression, and a well-defined fovea 
at the vertex ; antenne with last five or six joints much thickened 
(like Nodonata); thorax very lightly collared and with a slight ~ 
fovea on either side behind; anterior angles prominent. Elytra 
somewhat impressed within the shoulder, widening into a faint 
transverse depression - (like denticollis) , and, like that species, an 
aberrant form. 
Hermesia, Lef. 
This genus of Lefevre’s was founded for C. auwrata, Oliv., a 
well-defined form from Cayenne, in which the hind tibia of the 
3 is strongly angulate within, at nearly the middle; body above 
brilliant metallic golden or coppery green. Mr. Jacoby joins with 
this species certain forms from Bugaba and Chiriqui. My four 
examples from these places include three of those referred to 
by Jacoby, and they are all ?’s. He also includes three specimens 
from Chontales described as Rhabdophorus violaceus, one of them 
said to be a ¢; the other two examples are before me and are 
2’s, ?.as to the ¢. What is probably another species, and at 
present lumped with aurata, is the Bolivian form, either green 
or cyaneous blue, but in which the dilation of the hind 3 tibia 
seems much less developed, but more 3’s of aurata from Cayenné 
should be in hand before separation.
