OOPTERINUS.— ATENISTES. 271 
7. Oopterinus glabratus, sp. n. (Tab. XIV. figg. 3, 3a, 0, 3.) 
Moderately elongate, shining, zeneo-piceous, the antenne and legs (the middle of the femora excepted) ferru- 
ginous or testaceous; glabrous above, the under surface and legs with a short, fine, scattered pubescence. 
Head convex, coarsely punctate, smooth between the eyes and excavate above them, the latter rather 
small, prominent and widely separated; rostrum stout, shorter than the prothorax, seriate-punctate, 
smoother along the middle. Prothorax long, globose anteriorly and much narrowed behind, sparsely, 
minutely punctate in front. Scutellum invisible. Hlytra gibbous, ovate, nearly twice as long as, and 
considerably wider than, the prothorax,smooth. First ventral segment sulcate down the middle in the ¢. 
Legs rather slender ; anterior femora usually with indications of an extremely minute tooth. 
Length 2-24, breadth 3-1, millim. (3 Q.-) 
Hab. Guaremata, Cerro Zunil, Quiché Mountains, Calderas, Capetillo, Duenas, 
Guatemala city (Champion). 
Found in plenty, at elevations between 4000 and 9000 feet. ‘This insect has more 
elongate elytra than O. bactrianus, the head is without the supra-ocular sulcus, the 
scutellum is not visible, and the anterior femora only have, at most, the faintest 
indication of a tooth. It is much smaller than O. levigatus, the head is deeply 
excavate above the eyes, the prothorax is more narrowed behind, the elytra are 
gibbous, and the legs are slender. 
Group ERODISCINA. 
Erodiscides, Lacordaire. 
The species of this group are nearly all Tropical American, and range as far north 
as Florida. The four recognized genera are feebly differentiated, and it is very doubtful 
if they can be maintained as distinct when the whole of the South-American species 
are studied. 
ATENISTES. 
Atenistes, Pascoe, Journ. Linn. Soc., Zool. x. p. 464 (1876) (sine descr.) ; Chevrolat, Ann. Soc. 
Ent. Fr. 1879, p. 6. 
In this curious genus, which includes a few Tropical-American species * and also 
one from Java, the knees and the apex of each elytron are armed with a long spine, 
the rostrum is slender and at least as long as the body, the second joint of the funiculus 
is not or very little longer than the third, and the tarsal claws are simple. I follow 
Chevrolat in adopting Pascoe’s name, though it was simply used by him to replace that 
of Toxeutes, Schénh., in the wide sense, on account of the latter being preoccupied.
