TOMODERUS. 219 
6. Tomoderus exiguus. 
Short, moderately broad, rather convex, shining, pale castaneous or reddish-brown, the head in one example a 
little darker; the head and prothorax very sparsely, the elytra more thickly, clothed with long, fine, 
semierect pubescence. Head transverse, smooth, obsoletely canaliculate on the vertex, the eyes very 
small; antenne rather short, slender, thickening a little outwardly, and with joints 9 and 10 strongly 
transverse, black or piceous, the basal joint usually a little lighter, the apical joint (except in one example) 
testaceous; prothorax narrower than the head, about one fourth longer than broad, very strongly 
constricted behind the middle, the posterior portion very little narrower at the base than the anterior 
portion, both (when viewed in certain lights) finely canaliculate ; elytra short, more than twice as broad 
as the prothorax, rather convex, widest a little before the middle, the usual post-basal depression exceed- 
ingly shallow or nearly obsolete, the surface confusedly and somewhat coarsely punctured, the punctuation 
becoming much finer beyond the middle; beneath coloured as above; legs testaceous or ferruginous, the 
femora sometimes a little darker, the latter moderately clavate. 
Length 12-12 millim. (¢ 9.) 
Hab. Gvuatemata, Senahu in Vera Paz 2800 feet (Champion). 
Six examples. This minute species resembles 7. brevicornis, from which it differs in 
its much smaller size and more slender antenne. The punctuation of the elytra is coarse 
and confused on the basal half, and the post-basal depression is very faint (as in 
T. brevicornis); the antenne are slender and piceous in colour, the apical joint usually 
testaceous and the basal joint ferruginous; the thorax is very finely canaliculate, and 
the top of the vertex also. The following species is more nearly allied to it. 
7. Tomoderus brevis. 
8 Short, broad, convex, shining, unicolorous reddish-testaceous or pale castaneous, the head and prothorax with 
~ < a few very fine erect hairs, the elytra sparsely clothed with long, fine, semierect pubescence. Head 
transverse, smooth, the eyes very small; antenne rather short, slender, thickening outwardly, joints 
9 and 10 strongly transverse, 1 and 2 testaceous, 3-6 or 3-7 fusco-testaceous, and 7-11 or 8-11 
flavo-testaceous, sometimes testaceous with the apical four or five joints yellower; prothorax narrower 
than the head, about one third longer than broad, very strongly constricted behind the middle, the posterior 
portion a little narrower at the base than the anterior portion, the latter usually (when viewed in certain 
_ lights) obsoletely canaliculate in front; elytra short, at least three times as broad as the prothorax, convex, 
without post-basal depression, moderately rounded at the sides, widest at the middle, the surface very 
sparsely, confusedly, and finely punctured, the punctures becoming very much finer beyond the middle, the 
sides almost smooth ; beneath coloured as above ; legs testaceous or flavo-testaceous, the femora mode- 
rately clavate. 
Length 14-13 millim. (¢ 9.) © 
Hab. Guatemata, Las Mercedes, Cerro Zunil, San Isidro, Zapote (Champion); 
Panama, Volcan de Chiriqui 3000 feet (Champion). 
Many specimens, both from Guatemala and the State of Panama. Of the same size as 
T. exiguus ; but differing from it in the colour of the antenne, the almost unchannelled 
thorax, and the shorter, broader, and more convex elytra, the latter much more finely 
and sparsely punctured, and without post-basal depression. In the Chiriqui specimens 
and in one of those from Zapote the antenne are testaceous with the apical four or five 
joints yellowish ; in all the others the intermediate joints are more or less infuscate. 
T.. exiguus appears to be confined to the Atlantic, and T. brevis to the Pacific slope.
