rather coarsely, deeply and strongly punctate, the punctures rather dense and 

 asperate laterally, decidedly sparse, rounded and not asperate toward the 

 middle. Elytra as wide as the prothorax and not more than twice as long ; 

 sides parallel and extremely feebly arcuate in basal three-fifths, thence very 

 broadly rounded behind ; disk with fine, very feebly impressed striae which 

 are finely but deeply, distinctly and very closely punctured ; intervals very 

 sjiarsely punctate, the punctures similar to those of the striae except that they 

 are slighth' asperate. Abdomen rather strongly, asperately punctate toward 

 base. 



Male. — Abdomen broadly and distinctly impressed in the middle toward 

 base. 



Length 5.0 mm. ; width 2.4 mm. 



California (Majave Desert). 



Allied somewhat to puberuhis, but distinguishable by its fecblr 

 impressed, closely punctured elytral striee, those of puberulus being 

 completely unimpressed and very distantly punctured, also by its 

 coarser, deeper, sparser, less asperate and not transversely crescentic 

 pronotal punctures, and much less posteriorly prominent basal angles 

 of the prothorax. 



N. laticeps n. sp. — Very robust, rather feebly convex, oblong, shining, 

 very feebly alutaceous, black ; head slightly rufescent ; pubescence short, 

 fine, sparse and recumbent, dark piceous in color. Hfad strongly transverse, 

 angulate behind the eyes, the sides convergent anteriorly from the basal 

 angles ; epistoma very broadly bilobed ; surface feebly convex, finely, sparsely 

 punctate, the punctures strongly granuliform ; upper lobe of eyes very minute ; 

 antenn;e nearly as in jmherulus, the third joint rather more than twice as long 

 as wide, the eleventh small. Prothorax two-thirds wider than the head and 

 rather more than one-half wider than long ; apex narrower than the base, 

 narrowly truncate between the advanced and very broadly rounded apical 

 angles ; base transverse, feebly sinuate laterally, the basal angles being right 

 not at all rounded and slightly posteriorly prominent ; sides almost jjarallel 

 throughout basal tliree-fourths, rather feebly arcuate, then rounded into the 

 extremely broad apical angles ; disk sparsely punctate, the punctures very 

 fine, rather feeble and transversely cresuentiform, not strongly asperate, a 

 little more noticeably so but not distinctly denser laterally. Elytra very 

 slightly wider than the prothorax and a little more than twice as long ; sides 

 feebly arcuate; apex ogival; humeri very broadly rounded; disk with dis- 

 tant, excessively feebly impressed rows of fine, closely-placed punctures, the 

 punctures of the intervals similar in size but a little more asperate, sparsely 

 and unevenly distributed. Abdomen finely, rather sparsely punctate, the 

 punctures becoming more asperate toward base ; pubescence rather long, fine 

 and abundant. L'(js bright rufous, rather long, the femora robust. 



M(dc. — Abdomen extremely feebly and Inoadly impressed in the middle 

 toward base. 



Length 5.8-6.4 mm. ; width 2.S-3.0 u)m.
