in granariits, the intervals are flat and finely punctate ; the hind 

 tibiae are fimbriate with equal spinules. 



By its elongate scutellum hccmorhoidalis has to be associated in our 

 fauna with fossor, haiiiatns and crraticns. 



Strategus julianus var. arizonicus new variety. 



Two fully developed male specimens from Prescott, Arizona, in my col- 

 lection differ from specimens from Texas by having the lateral prothoracic 

 horns acute or subacute and not broad and more or less obliquely truncate at 

 apex as in typical julianus; the median ridge of prothorax is flatter and the 

 lateral impressions are not as deep as in typical julianus and feebly or not 

 at all rugose ; the clypeus is acutely triangularly emarginate. The female does 

 not differ from typical juHaiius. 



In about twenty-five males from Texas, from small males with 

 feebly developed cephalic and prothoracic armature to large, fully 

 developed males the lateral thoracic horns are broad at apex and 

 not pointed and agree with Burmeister's description, " cornibiis pronoti 

 maris posticis latis, alccfonnihns." Strategus julianus was originally 

 described from Mexico. 



Heterobrenthus texanus new species. 



Male. — Narrow elongate. Head quadrate, constricted behind, vertex, con- 

 vex, sulcate, at base slightly emarginate with the 

 angles somewhat depressed and projecting. Beak 

 as long as the prothorax, more or less distinctly 

 sulcate, between the eyes and the antennal inser- 

 tion broader than before the latter, apex dilated- 

 Antenna inserted at about the middle of the beak, 

 reaching a little beyond the middle of the pro- 

 thorax, joints two to eleven gradually increasing 

 in length and width, the first seven antennal joints 

 glabrous, the last four pubescent. Prothorax elon- 

 gate, apex and base truncate, at base constricted, 

 sides arcuate, narrowing to apex ; surface smooth, 

 shining, with a few very small punctures. Elytra at 

 base as wide as the prothorax in its widest part, 

 feebly narrowing to apex, which is slightly sinuate 

 truncate, surface shining, the two striae near suture 

 deeply impressed and impunctate, the outer ones 

 represented by rows of more or less distinct and 

 rather coarse punctures, the intervals at apex more 

 or less costiform ; color piceous, a spot at base on
