and the last dorsal feebly sinuate at tip. In my opinion they 

 should be regarded as closely allied but true species and not 

 mere geographic subspecies. The representatives of albionica 

 before me ai-e from Idaho (Coeur d'Alene) and Washington State^ 

 those of propinqua from Michigan and Massachusetts (Lowell). 



:NISAXIS Csy. 

 The species of this genus are smaller as a rule than in Reichen- 

 bachia, and can readily be distinguished by the complete oblitera- 

 tion of the vertexal fovese, and the median of the three basal foveas 

 of the elytra ; the abdominal carinse are as widely separated as in 

 Decarthron, but are shorter and more feebly developed. The 

 four components in my cabinet belong to two distinct groups and 

 may be separated as follows : — 



Male with the third dorsal segment broadly flattened, the median parts toward 

 apex feebly tumid and bearing long erect setse. 

 Elytra of the male less abbreviated, the abdominal carinse scarcely }{ as 

 long as the segment ; pubescence abundant and conspicuous. 



tomentosa Aube 



Elytra decidedly shorter than wide and more arcuate at the sides; abdominal 



carinse generally a little longer ; body smaller, with the pub escence less 



abundant subsp. cincinnata Csy. 



Male with the second dorsal profoundly excavated in nearly median half, the 

 excavation very irregular and with complex modifications. 

 Head large, subequal in width to the prothorax. Maritime regions of Texas. 



maritima Csy. 

 Head much narrower than the prothorax. Missouri valley regions. 



parTiceps n. sp. 

 The last species of the table may be thus described from the 

 male : — 



N'. parTiceps. — Elongate, subparallel and only moderately convex, pale 

 and uniform rufo-testaceous and polished throughout ; elytra coarsely, sparsely 

 and obsoletely variolato-punctulate, the remainder impunctate ; pubescence 

 moderate in length, coarse, recurved and rather sparse. Head scarcely ^5 as 

 wide as the prothorax, the front near the feeble antennal prominences very 

 slightly impressed and subpunctate ; eyes rather large but only slightly promi- 

 nent, at less than their own length from the base. Antennse barely as long as 

 the head and prothorax, the club gradually formed and rather stout ; second 

 joint but little smaller than the first ; three to seven equal in thickness and 

 narrower, the third obconic and distinctly longer than wide ; eighth slightly 

 transverse ; ninth distinctly and tenth moderately, transverse. Prothorax re- 

 latively large, % wider than long, widest and prominently though evenly 

 rounded at the sides before the middle; apex scarcely 3^ the maximum width
