rufo-testaceis. Long. '4 unc. In sandy places. This species approaches very near to 

 the Rocky Mountain one, which I have considered as cribricollis (Dej.), but the head 

 and thorax are still more coarsely and densely punctured, and the latter more narrowed 

 behind ; the elytra are obliquely truncate, in some specimens they are rufous at base, 

 but have no distinct humeral spot, the interstices are flatter, with smaller and more 

 numerous punctures. 



3 By an error of spelling, I formerly wrote Aplochile. 



4 D. apicalis. Subelongatus, nigro-ccneus nitidus, clypeo bidentato, fronte angulatim 

 leviter impressa, thorace ovali, latitudine fere longiore, antice vix angustato, elytris 

 thorace parum latioribus, lateribus vix rotundatis, stria marginali ad humerum abbrevi- 

 ata, tenuiter striatis, striis ante medium punctatis, 2 11<Ja 7 ma 8 va que ad apicem exaratis, 

 interstitiis planis 3' tripunctato, antennarum basi palpisque piceis, vel rufo-piceis. 

 Long. -12 unc. The anterior tibia; have the outer spine scarcely longer than the inner, 

 and but slightly curved, on the outer edge is a distinct tooth, and above it two other 

 very obsolete denticles. 



5 D. seneolus. -SSneus, elytris nitidissimis, clypeo valde bidentato, fronte transversim 

 profunde impressa, thorace subgloboso, antice non angustato, lateribus antice leviter 

 rotundatis ; elytris fere parallelis, apice rotundatis, striato-punctatis, punctis pone 

 medium extemeque obliteratis, stria sutur aliapice distincta, duabusque aliis (exteriore 

 longiore) brevibus exaratis, marginali ad humerum desinente, interstitio 3 io tripunc- 

 tato. Long. -15 unc. Two specimens. The terminal spines of the anterior tibiae sub- 

 equal, scarcely curved ; the outer edge with two denticles, the superior scarcely visible. 



6 D. parvus. This species is only half the size of D. globulosus, but like it has a 

 transverse thorax, narrowed in front. The clypeus is less deeply emarginate, the frontal 

 sulcus not so deep, the elytral stria; and points deeper : the internal terminal spine of 

 anterior tibiee only one half the length of the outer one ; the external margin has but 

 one denticle. Long. '09. 



7 D. longulus. This differs from D. globulosus, in having the thorax subglobose, 

 (the length being equal to the breadth,) not narrowed in front; the elytra are more 

 elongate, the strios are deeper, and can be traced to the apex, although the points vanish 

 at the middle. The 3 rd interstice is 3-punctate, the 8 th stria profound at apex ; antenna 

 fuscous at apex ; internal spine of anterior tibia; 3-4 as long as the outer one, on the 

 bxiter margin, the lower denticle acute, the upper one obsolete. Long. -11.
