before the rounded apical angles, apical margin truncate-emarginate. Thorax at 

 base slightly more than twice as wide as long ; sides somewhat explanate, especially 

 near basal third and feebly arcuate ; hind angles rounded, front angles feebly 

 rounded ; disk remotely not coarsely punctate, punctures at sides a little denser and 

 coarser. Elytra about one and one half times as wide at base, gradually widening 

 to apex ; costse feebly convex and with an irregular row of punctures; intervals, be- 

 tween the geminate rows of punctures, enclosing the costee, confusedly punctate.' 

 Propygidium transversely impressed, the impression not more coarsely punctate than 

 the rest ; last abdominal spiracle somewhat prominent. Pygidium sparsely punctate, 

 the punctures not coarser than those of propygidium ; apex somewhat inflexed and 

 rotundate-truncate in the male. Underside coarsely and sparsely punctate, meta- 

 sternum finely at middle but more densely at sides ; front tarsi tridentate ; tarsal joints 

 at apical half densely clothed with pale-yellowish, fine pubescence ; claws cleft, the 

 lower part broader, slightly shorter than the upper and truncate at apex ; maxillary 

 palpi in the male subcompressed and broadly arcuate on inner side, rounded at apex ; 

 in the female narrow, elongate with apex obliquely truncate ; labrum broadly emargi- 

 nate. Length 8.5-9 '""''• 



Huachuca Mountains, Arizona. 



Distinguished by the explanate, scarcely deflexed sides of thorax 

 finely and densely pubescent tarsal joints at apical half, and the broad 

 last joint of maxillary palpi of the male. 



Diplotaxis pubipes, new species. 



Oblong-oval, black with faint reneous luster. Head remotely punctate, punctures 

 not coarse ; clypeal suture obliterated at middle, faint at sides ; genze feebly prominent ; 

 clypeus more coarsely and densely punctate than the head, sides and apex reflexed, 

 apical angles rounded, apical margin very feebly emarginate. Thorax twice as wide 

 at base as long ; apex slightly narrower than base ; sides feebly arcuate ; basal angles 

 slightly rounded ; basal margin with a broad antescutellar depression ; surface with 

 moderately large, well separated punctures. Elytra one and a half times as long as 

 wide ; sides gradually widening to apex ; punctuation confused between the geminate 

 rows of punctures; costre feebly elevated with a single row of slightly smaller punc- 

 tures than those of the intervals ; at base a circumscutellar impression. Propygidium 

 with a deep, well limited, transverse, apical impression ; feebly punctate, except the 

 transverse impression which is coarsely punctate. Pygidium coarsely, remotely punc- 

 tate. Labrum feebly, broadly emarginate. Maxillary palpi oval. Front tibiae tri- 

 dentate. Tarsi densely clothed over nearly the entire underside with yellowish hairs. 

 Claws cleft, inferior portion shorter and broader than the upper and oblique at apex. 

 Abdominal segments sparsely and coarsely punctate. Length 8.5 mm. 



Brownsville, Texas (Esperanza Ranch). 



The distinct antescutellar thoracic and circumscutellar elytral im- 

 pressions, together with the densely pubescent tarsal joints, render the 

 recognition of this species easy.
