The pubescence occupies nearly the entire under -surface of the 

 tarsal joints and is much denser than in tarsalis. By description it 

 seems to be related to the Mexican juguilensis, which has the elytra 

 very coarsely, subconfluently punctate, the lateral margin sinuate in 

 front, the basal thoracic and scutellar impressions absent and the front 

 tibiae of male bidentate. 



The specimen described above is apparently a male, which I owe 

 to the kindness of my friend Mr. Gustav Beyer, who collected two or 

 three specimens at light. 



Diplotaxis californica, new species. 



Oblong-oval, black or dark ferruginous. Head coarsely, cribrately punctate ; 

 genae not prominent, almost continuous with the sides of the clypeus ; clypeal suture 

 only visible at sides; above the clypeal suture, from side to side, a transverse, slightly 

 arcuate, prominent swelling, which gives the clypeus, together with the reflexed 

 front margin, the appearance of being deeply excavated ; apical margin scarcely 

 emarginate ; angles' rounded. Thorax at base twice as wide as long ; sides strongly 

 arcuate behind middle, obliquely narrowing to the hand angles, which are obtuse, 

 slightly less strongly narrowing to apex, before these feebly sinuate ; near the side 

 margin a distinctly impressed line, which is less distinct near apex ; surface densely 

 and coarsely punctate, slightly less densely at middle of disk. Elytra slightly wider 

 than the thorax at base, one and a half times as long as wide, feebly widening behind ; 

 costse almost obliterated, but indicated by the row of smaller punctures ; first inter- 

 val, between the sutural row and the geminate row of punctures enclosing the first 

 costa, confusedly punctate, the others forming almost regular rows of punctures. 

 Propygidium sparsely and much more finely punctate than in the transverse apical im- 

 pression. Pygidium coarsely punctate. Labrum broadly and feebly arcuate-emarginate. 

 Maxillary palpi oval. Anterior tibiae tridentate. Claws toothed at middle. Ventral 

 segments transversely coarsely punctate at apex, feebly so at base ; second ventral 

 segment with two more or less distinct elevations on each side of middle in both 

 sexes. Length 8 mm. 



Tulare Co., California (Dietz). 



The anteclypeal elevation in this species which is slightly im- 

 pressed at middle in one female, is much more prominent than in any 

 of my specimens of excavata and by this and the elevations on the 

 second ventral segment californica Avill be readily recognized. 



The claws are described as being toothed, but are really cleft, with 

 the lower part very short and the oblique apical truncation feeble. 



Diplotaxis beyeri, new species. 



Elongate, ferruginous. Head rather flat, coarsely punctate ; gense prominent ; 

 clypeal suture distinct, arcuate at middle ; clypeus as long as the head, coarsely 

 punctate, apical margin strongly reflexed and scarcely emarginate, angles broadly
