28 H. C. FALL. 



Very few specimens of this species have been seen, all from 

 Texas, without indication of exact locality, and nearly all col- 

 lected years ago by Belfrage. It is most closely allied to villosa, 

 but is a rather larger species with wider head, clypeal margin 

 at most truncate, never sinuate, the truncation narrower, the 

 prothorax much less coarsely punctate and evidently more 

 finely so than the elytra. There is also an apparently con- 

 stant difference in the suture separating the ligula from the 

 mentum, this being nearly or quite straight in villosa and 

 without raised margin at middle. 



10. D. brevisetosa Linell. 



Ovate, convex, rufo-ferruginous to rufo-piceous, polished, shining, 

 sparsely hairy, the hairs very short and much inclined. Mentum 

 distinctly declivous anteriorly from about the apical two-fifths, arcuate 

 ridge and setae distinct. Head convex, moderately coarsely punctate, 

 the punctures close on the clypeus but well separated posteriorly; 

 clypeal suture obliterated except near the eyes, margin rounded from 

 side to side, or with the middle subtruncate for a short distance. 

 Prothorax a little less than twice as wide as long, widest at a point 

 just in advance of the middle, thence just visibly convergent or sub- 

 parallel to base, moderately strongly convergent in front, base angles 

 nearly right, apical angles a little obtuse as viewed from above; disk 

 evenly convex, punctuation somewhat variable, the punctures as a 

 rule separated from one-half to their own diameters at the middle, 

 slightly closer laterally. Elytra scarcely wider at base than the 

 thorax, wider behind, barely three times as long and scarcely one- 

 third wider than the thorax; costae feeble, all the intercostal areas 

 confusedly rather closely punctate, the punctures equal in size to 

 those of the thorax; costae with single lines of finer punctures. Body 

 beneath rather densely punctate at sides, metasternum and abdomen 

 nearly smooth at middle Upper tooth of front tibia about equally 

 distant from base and apical tooth; claws cleft at tip, the lower por- 

 tion broader and nearly as long as the upper. Length 6-7.25 mm.; 

 width 3.25-3.6 mm. 



Habitat. — Brighton, Nueces Co., Texas (type series) ; Goliad, 

 Texas, April 18th (Schwarz). Other examples in the National 

 Museum collection are doubtless from Texas, though they 

 carry no locality label. 



The tabular characters are amply sufficient for the recog- 

 nition of this very distinct species, but there may also be added 

 as equally characteristic when compared with the other hairy
