thirds wider than tlie prothorax. the sides parallel and scjircely more arcuate 

 behind, the apex obliquely rounded from apical third; disk obsoletely im- 

 pressed within the humeri and on each side of the suture near the scutellum, 

 coarsely, sparsely punctate, finely toward apex, the pubescence rather long, 

 coarse, sparse, cinereous, subdecunibent and evenly distributed, the erect setie 

 long, coarse, rather numerous and conspicuous. Under surface and legs 

 minutely, closely punctulate, the abdomen coarsely pubescent. I.,ength 3.0 

 mm. ; width 1.1 mm. 



Nevada (Elko). Mr. Wicklmm. 



Three males before me agree very w^ell among themselves and 

 have the tips of the elytra obliquely truncate near the suture, 

 and the fifth segment scarcely visibly and transversely impressed 

 near the apex, but the fourth specimen, also a male, differs in 

 form and color, having the elytra larger and longer, almost en- 

 tirely' blackish, and the thoracic process more strongly crenulate. 

 I think, however, that it can only represent a varietal modifica- 

 tion ; it is labeled " Nevada," without more precise indication of 

 locality. 



N. tilliilboldti. — Stout, somewhat shining, pale, ochreo-test<iceous 

 throughout, the abdomen just visibly infuscate posteriorly; elytra with two 

 subconfluent scutellar spots, which are prolonged obliquely outward to the 

 lateral edges, and a broad transverse fascia somewhat behind apical third, pro- 

 longed broadly along the suture, abruptly ending just behind basal third, of 

 black; apical regions not maculate. Head much narrower than the prothorax, 

 finely, densely punctate and pubescent; eyes large, much longer than the tem- 

 pora; anteuniv rather short and stout, the tenth joint but little longer than 

 wide. Prothorax transversely oval, finely and somewhat sjiarsely punctate, 

 the coarse yellowish decumbent pubescence abundant; horn strongly developed, 

 spatuliform, gradually and strongly narrowed to base and margined throughout 

 with large prominent and distant, obtusely rounded teeth, the crest very long 

 and narrow, defined at the sides only by a series of elongate elevations, not 

 defined at the acute apex. Elytra distinctly less than twice as long as wide, 

 not quite twice as wide as the prothorax, not dilated behind, the sides parallel 

 and nearly straight, o])li(|uely narrowed and then obtusely rounded in apical 

 third or fourth; humeral imiiression at base narrow and well marked, the 

 scutellar also slightly visible; disk strongly but not very coarsely, rather 

 closely punctiite and shining, the decumbent pubescence coarse but only 

 moderately long and dense; erect setie abundant, very long, coarse and con- 

 spicuous throughout the upper sui'face. Length 3.6 mm.; width 1.25 mm. 



California (Hoopa Val., Humboldt Co.). 



The single specimen before me, probabl}- female, represents an 

 interesting modification of the monodon group, departing r.idically 

 in type of maculation near the base of the elytra, and differing
