dage of the outer subhumeral stria near the end of the oblique 

 humeral, there being no vestige of this in sellalus. 



H. SCUlpticauda n. sp. — Moderately broad, convex, resembling ulkei 

 in color and form. Head minutely, sparsely punctate ; frontal stria entire, 

 transverse at apex ; mandibles finely but deeply, extremely densely and con- 

 spicuously punctate. Prothorax not quite twice as wide as long, the sides 

 moderately convergent, broadly, nearly evenly arcuate from base to apex ; 

 marginal stria fine, entire ; outer lateral entire, arcuate at apex ; inner almost 

 entire, nearly straight, slightly approaching the outer toward base ; disk 

 minutely, sparsely punctulate, the punctures more distinct near the basal 

 angles ; there is a small puncture just within the posterior extremity of the 

 inner stria, three minute and remote punctures along the fine marginal stria 

 and a short deep stria before the scutellum, the latter equilateral and unim- 

 pressed. Elytra one-third longer and but slightly wider than the prothorax, 

 widest very near the base, the sides feebly convergent, broadly and feebly 

 arcuate throughout ; apex oblique, broadly rounded ; inflexed fianks bisul- 

 cate ; punctures of the lateral series extremely minute and remote; outer 

 subhumeral obsolete behind, represented by a short arcuate stria near the 

 end of the oblique humeral ; inner subhumeral represented by a series of 

 punctures close to the first dorsal in apical third ; first three dorsals entire, 

 moderately coarse ; fourth and fifth completely wanting ; sutural deep and 

 distinct from basal third to apical fifth. Propygidium extremely coarsely, 

 deeply but variolately punctate, the punctures mingled with minute punc- 

 tules ; pygidium strongly, rather closely punctate, more finely so toward 

 apex. Prosternal lobe broadly, evenly rounded, finely but strongly margined ; 

 posterior process dilated ; mesosternum long, the emargination deep, broadly 

 sinuate ; marginal stria entire ; sides strongly convergent from the base. 

 Anterior tibise strongly bidentate ; posterior with two rather even external 

 series of spinules. Length 6.5 mm. ; width 4.4 mm. 



New Mexico (Fort Wingate). 



This species is allied to instratus and ulkei, but differs in the 

 minutely, very densely punctate mandibles and coarse sculpture of 

 the pygidia; the propygidial punctures are ova], more dense and 

 even in distribution than in ulkei, generally separated by less than 

 their own dimensions, and are coarser than in any other species of 

 Hister known to me. The outer pronotal stria is more distant from 

 the margin than in either of the species mentioned. The three 

 small punctures along the marginal stria are present also in instratus, 

 ulkei and other species, and seem to be very constant. 



Group Merdarius. 



Sides of the prothorax not ciliate ; mesosternum emarginate; 

 outer subhumeral stria entire ; elytra with four subentire discal
