8. Nuptis laticollis. 
Black, shining. Head exceedingly minutely, sparsely punctate, the eyes (¢) very large, rather narrowly 
separated ; prothorax one-half broader than long, very sharply margined at the sides and in front, the 
sides broadly rounded anteriorly, flexuous and feebly converging behind, the base strongly bisinuate and 
deeply grooved within on either side of the middle, the hind angles acute, the surface with exceedingly 
minute scattered punctures, the apex raised in the middle; elytra elongate, parallel, much wider than the 
prothorax, with rows of distantly placed, oblong, coarse punctures, which become much finer towards the 
apex and a little finer towards the suture, without trace of strie, the interstices flat, almost imperceptibly 
punctate; beneath smooth, shining, the ventral surface very finely, longitudinally wrinkled; prosternum 
excavate in front, acutely produced behind; mesosternum horizontal, V-shaped, vertical in front, and 
deeply excavate for the reception of the prosternum. 
¢@. Anterior femora and anterior tibiz each armed with a sharp tooth on the inner side beyond the middle. 
Length 21, breadth 8 millim. (¢.) 
Hab. Panama, Chiriqui (77ré¢sch). 
One male example. Larger and broader than J. corticalis, the thorax very much 
more transverse and acutely margined, the head almost smooth, the eyes very large, 
the pro- and mesosternum differently shaped, the anterior femora toothed in the male. 
The epistoma is simple in the male, as in WV. validus, N. tenebrosus, and NV. corticalis. 
GEATUS (p. 111). 
@atus chevrolati (p. 111). 
‘Two species were confused by me under this name, and some of the localities quoted 
refer to tne following. 
2. @atus similis. 
Closely resembling @. chevrolati, but with the strix of the elytra finely and closely crenate-punctate 
throughout. . 
g. The femora shallowly grooved along their lower edge towards the base, the groove filled with fine fulvous 
hairs ; the tibiee from the middle to the apex densely clothed with fulvous hairs within, the anterior pair 
bowed inwards.
