Dec, ipM-] Schaeffer: North American Onthophagus. 299 



Huachuca, Mts., Arizona, and have specimens from Nogales, Arizona, 

 collected by F. W. Nunnenmacher. It is a little larger than tubercu- 

 lifrons,oi dull, uniform, brownish color with very feeble bronze lustre. 

 The clypeus is more or less reflexed at apex and anteriorly emargi- 



Inate. The head of the male has no carinse nor horns or tubercles. 

 The prothorax of the male is produced at middle into a short cone- 

 like projection which is indicated more or less in the prothorax of the 

 female. The anterior tibise of the male are much elongated and have 

 at apex within the emargination a pencil of stiff, long hairs.

 Originally described from Colombia and Venezuela this species 

 I extends its range as far north as Texas (Brownsville). 



Head, prothorax, metasternum and legs metallic green, shining, 

 except the head, which is dull ; elytra and abdomen with very faint 

 bluish or rarely greenish tint, the former generally with a variable 

 •number of small, reddish-yellow spots from base to apex, rarely 

 without spots. The head in the male is very sparsely punctate, the 

 lower carina is absent and the upper carina is represented on each 

 1 side by a small, rather feeble, arcuate ridge. The prothorax is rather 

 \ coarsely, but sparsely punctate, slightly declivous in front and at 

 middle produced into a very short lobe. The elytra are alutaceous 

 with a somewhat greasy appearance, and the intervals are feebly and 

 finely punctate. The anterior tibi?e of the male are greatly elongated 

 and have within the apical emargination a pencil of stiff hairs, the 

 anterior tibiae are normal in the female and the head has the usual 

 two carinse. It is smaller than O. janus. 



Onthophagus texanus new species. 



A few specimens which I have taken in Brownsville, Texas, 

 together with 0. landolti differ from that species in having the pro- 

 thorax more or less yellowish at sides, the elytra dull, brown, with 

 tihe yellow spots forming more or less distinct longitudinal vittae; 

 prothorax of the male without anterior modification, the anterior tibiae 

 scarcely differ from those of the female and are without the pencil 

 of hairs at the apical emargination.
