Diplotaxis sparsesetosa, new species. 



Robust, black. Head coarsely and densely punctate ; genje distinct, but con- 

 tinuous with the sides of the clypeus ; clypeal suture absent ; clypeus more densely 

 punctate than the head, apical margin feebly reflexed and scarcely emarginate, angles 

 broadly rounded. Thorax twice as wide at base as long ; apex slightly narrower 

 than base ; sides arcuate ; surface very coarsely punctate, punctures well separated on 

 the disk, dense at sides. Elytra not quite one and a half times as long as wide at 

 base, widening towards apex ; costa; distinct and with a row of smaller punctures ; 

 punctures of intervals, between the geminate rows of punctures, confused, coarse, 

 but not dense, each bearing a very short, pale hair, which is more apparent when the 

 specimen is viewed laterally. Propygidium with a deep, transverse, well-limited 

 and coarsely punctate impression. Abdominal spiracle rather prominent. Pygidium 

 extremely coarsely and confluently punctate. Labrum broadly arcuateemarginate. 

 Anterior tibiie tridentate, the upper tooth twice as far from the second, as the latter 

 from the first. Claws cleft, the lower part broader and much shorter than the upper 

 and truncate at apex. Metasternum and abdomen coarsely but not densely punctate, 

 the latter still more coarsely punctate at sides. Length 9 mm. 



Texas (Dietz). 



From the above described minicata this species differs in being 

 more robust, the elytra widening towards apex, much shorter and 

 finer pale hairs and the elytral punctuation different. 



By description it seems to be allied to Linell's brevisetosa, but 

 that species has the lower part of the cleft claws nearly as long as the 

 upper. Superficially sparsesetosa resembles connata somewhat, but is 

 widely separated from that species. In describing connata I compared 

 it with Lachnosterna epigaa which is not correct ; it has rather the 

 form of cribrosa than epigcea. 



Diplotaxis arizonica, new species. 



Oblong, ferruginous, clypeus on each side rather strongly sinuate, each elytral 

 puncture with a short, recumbent pale hair. Head coarsely and densely punctate ; 

 clypeal suture impressed ; gense not prominent, continuous with the clypeus ; the 

 latter broadly emarginate in front, sides rather strongly sinuate near apical angles, 

 margin and front reflexed. Thorax twice as wide at base as long; sides broadly arcu- 

 ate slightly behind middle, strongly narrowing to base and slightly sinuate before the 

 latter, obliquely narrowing to apical angles, the latter acute, basal angles nearly rec- 

 tangular ; disk with moderately coarse, but not densely placed punctures. Elytra 

 slightly wider than the thorax at base ; first costa well defined, second more obscured 

 by the punctures at sides, both costce almost without punctures; the row of punc- 

 tures on each side of the costse distinct, the punctuation between these confused ; 

 from each of the elytral punctures arises a short, semi-erect, pale hair. • Pygidium 

 coarsely but not densely punctate, propygidium transversely impressed at apex and 

 coarsely punctate, posterior spiracle moderately prominent. Underside coarsely punc- 

 tate, labrum moderately deeply arcuate-emarginate ; last joint of maxillary palpi
