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. 



* D. apicalis. — Subelongatus, nigro-a^neus nitidus, clypeo bidentato, fronte angulatim 

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

 thorace parum latioribus, lateribus %"ix rotundatis, stria raarginali ad humerum abbrevi- 

 ata, tenuiter striatis, striis ante medium punctatis, 2'i'3a 7"'" 8^aque ad apicem exaratis, 

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

 Lonw. -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. 



s D. a;neolus. — iEneus, elytris nitidissimis, clypeo valde bidentato, fronte transversira 

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

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

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

 lono-iore) brevibus exaratis, marginali ad humerura desiuente, interstitio 3'° tripunc- 

 tato. Lon". -15 unc. Two specimens. The terminal spines of the anterior tibia> sub- 

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

 6 D. par-i-us. — 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 strise and points deeper : the internal terminal spine of 

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

 one denticle. Long. '09. 



T 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 stria; are deeper, and can be traced to the apex, although the points vanish 

 at the middle. The Z^ interstice is 3-punctate, the 8'h stria profound at apex ; antennae 

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

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