Coleoptera of the Family Rutelide. 545 
margin is a row of hair-bearing punctures. Sternal 
process rather long and thick, concave on its inner side, 
thickened and truncate at the apex. Female. 
Hab. New Grenada. 
Besides the difference in colour, this species differs 
from A. pilosula in being less rotundate, more oblong, 
in the scutellum being a trifle longer, and in the almost 
entire absence of impressed lines on the elytra. 
I think Chlorota rotundata, Blanch. (Cat. Mus. Paris, 
p- 208), must closely resemble this species, and, if Prof. 
Blanchard has overlooked the long sternal process in 
placing his species in the genus Chlorota, mine may be 
only a variety of his insect. 
THyripium, Burm. 
The species here described differ from Antichira with 
small scutellum, in having the mandibles not notched on 
the outer edge; and differ from Chlorota in having a long 
sternal process. 
A. Larger claw to all the tarsi bifid. Species 1—5. 
1. Thyridiwm Sommeri, 0. s. 
Obovatum, convexum, nitidum, subtus nigrum; capite, 
thorace, scutello tibiisque cupreis, elytris flavis, pygidio 
striolato et femoribus piceis. Mas. Long. 8 lin. 
Short, oblong-obovate. Clypeus short, very closely 
and strongly punctured; head sparingly and finely 
punctured. Thorax distinctly angular at the sides; 
sparingly and finely punctured, with a line of rather 
strong punctures within the incrassated lateral margin ; 
the base slightly oblique on each side, with a slight lobe 
in the middle, which is very slightly emarginate. Scu- 
tellum a curvilinear triangle, rather acute at the apex, 
nearly 2 millimetres long. Llytra yellow, with the 
suture tinted with fuscous (but with no sutural stria), 
convex, a little broader in the middle than at the base 
and apex, evenly and gently arcuate at the sides. Sternal 
process moderately long and very thick, gently arched, 
not distinctly enlarged at the apex. The sterna, femora, 
and abdomen are sparingly clothed with long pale 
pubescence.
