TABLE OF NORTH AMERICAN SPECIES OF TROPIDERES 



1. Body elongate, prothorax set off from elytra by the constriction behind 



the prothoracic ridge. Epistoma apically bidentate 2, 



Body compact; prothorax set close to elytra, constriction behind ridge not 

 so strong. Epistoma apically emarginate, not dentate rectus LeCoute. 



2. Sides of prothorax strongly sinuate, due to prominence of lateral prolonga- 



tions of prothoracic ridge bimaculatus Olivier. 



Sides of prothorax almost evenly rounded barberi, new species.

The accompanying sketches illustrate the face (fig. 23), under 

 side of head and mouth parts (fig. 24), side of head (fig. 25), pro- 

 tarsal claw (fig. 26) , metatarsal claw (fig. 27) . 



The mesotarsal claw is toothed, and the metatarsal claw slightly 

 appendiculate in one view. 



TROPIDERES BARBERI, new species 



Length, 3-3.5 mm. Similar to T. timaculatus in general mark- 

 ings and appearance but differing by having the punctuation of the 

 head and thorax much finer, and the sides of the prothorax evenly 

 convex. The angles of the apical emargination of the beak are never 

 acute, dentiform as in himaculattis. The elytral tuberculation is 

 almost obsolete. 



Described from eight specimens collected at Esperanza Ranch and 

 at Los Borregos, near Brownsville, Tex., May 18 to June 6, 1904, 

 by H. S. Barber.
