of the field notes and experimental records now in the files of 

 the Bureau. The following description is published by offi- 

 cial pennission. 



In making out the diagnosis. I have tried to follow the gen- 

 eral outline laid down by Dr. Blaisdell*, without attempting 

 his extreme refinement of detail. The new species nms easily 

 to his subgenus Trichclcodes and is readily separable from 

 either of the two already described by its much smaller size 

 and different vestiture. It is probably ver\^ loc:il in habitat, 

 otherwise it seems as if specimens must have come to hand 

 in some of the numerous collections made in the southwest- 

 ern states during the past fifty years. 



Eleodes barbata new species. 



Ovate, about twice as long as wide or occasionally a little more 

 elongate, clothed with sparse, curved, golden hairs, intermixed with 

 very much longer straight^ erect, black ones. 



Head feebly convex, frontal suture hardly visible and then only 

 in certain lights ; punctuation strong but not coarse nor very dense, 

 with a tendency to form indistinct series radiating from the center of 

 the vertex ; hairs similar to those on the prothorax but shorter. An- 

 tennae reaching about two-thirds to the prothoracic base, outer three 

 joints moderately incrassate, hardly compressed, third joint scarcely 

 or barely eqiral to the next two taken together, fourth and fifth sub- 

 equal, eighth hardly larger than the seventh. 



Pronotum widest near the middle, about three-fourths as long as 

 wide, disk moderately convex from side to side, strongly shining, 

 golden hairs of the inner coat numerous but not obscuring the sur- 

 face, long black hairs sparser, punctures strong and deep, of moderate 

 size, separated by their own diameters or more on the median area, 

 closer and more confused at sides, where they are distinctly muricate. 

 Apex arcuately emarginate, finely beaded on each side of the middle ; 

 sides nearly evenly arcuate, a little more rapidly narrowed posteriorly, 

 distinctly margined, the bead fine, attaining the base which is truncate, 

 finely margined at middle, a little more strongly at sides, subequal to 

 the apex : hind angles small but distinct. Propleurae polished, rather 

 strongly, irregularly and more or less rugosely punctured. 



Elytra oval, strongly shining, widest along the middle third, base 

 truncate, humeri rounded, sides more arcuate basally and apically, sub- 

 parallel medially ; apex rounded, obtuse, disk convex on the dorsum, 

 more strongly so laterally, posteriorly rather suddenly but not quite 

 vertically declivous ; surface very densely, seriately but not quite reg-
