Temnochila, Gemminger & Harold, Cat. ii. p. 839. 
This genus includes about sixty-five species, and has a wide distribution. By far the 
larger number of its representatives, however, are limited to the New World, where it 
~ extends from the United States of North America to Uruguay. 
Several species have been recorded by Reitter as occurring in our region that have 
not been met with by any of the collectors employed by the editors of this work. I 
have little doubt that some of these Temnochile have been improperly assigned to 
Central America: the material used by Reitter was gathered from very various sources, 
a large part of it coming from old collections, in which, as is well known, mistakes as 
to localities are by no means infrequent. 
There is a great general resemblance between the species of Temnochila, so that it is 
difficult to distinguish them by diagnostic characters. An inspection of the following 
Key will give an idea of the arrangement I have adopted, and thus facilitate the 
determination of our species :— 
Front tibiz digitate at the apex externally. (Species 1, 2, forming group A.) 
Tibiz not digitate at the apex externally. 
Prothorax with the lateral margins more or less thick, and the front angles 
more or less produced. Groups B to F. 
Prosternum with a margin in the middle behind, connected on 
either side with the apices of the epimera . . . Group B. Species 3-6. 
Prosternum behind the cox excessively coarsely punctate but 
not margined; mandibles short . . . . . . Group. Species 7. 
Prosternum behind the coxe not margined, excessively coarsely 
punctate; mandibles and labium elongate . . . Group D. Species 8. 
Prosternum behind the coxz smooth, not conically prominent, 
without margin ; mandibles and labium short. . Group E. Species 9-25. 
Prosternum with conically protuberant and polished apex. 
Group F. Species 26-31. 
Prothorax with the lateral margins extremely fine, the front angles not at all 
produced . . . . ee ee ee eee ee) 6Group G. Species 32-43. 
Group A.—Anterior tibie thicker towards the extremity, with the outer angle somewhat 
prolonged and acuminate. (Species 1, 2.) 
1. Temnochila digitata, sp.n. (Tab. XIII. figg. 3; 3a, anterior tibia.) 
Fusca, supra senescens, convexa, antennis pedibusque rufis vel piceis; capite angusto, anterius canaliculato, 
canalicula lata, minus profunda, ad fundum plana; prothorace sat crebre et fortiter punctato, ad latera 
utrinque pone medium profunde impresso, post impressionem evidenter quasi-denticulato ; elytris seriatim 
subtiliter punctatis, interstitiis parce remote subtiliterque punctatis. 
Long. 10-15 millim.
