DASYTES PAYK, NEW SPECIES OF 183 



Male. Somewhat narrow. Fifth ventral segment truncate, adjacent 

 surface rather broadly and lunately impressed ; pygidium arcuately emar- 

 ginate, lateral angles rounded. 



Female. Somewhat broader. Fifth ventral arcuately rounded at 

 apex, sometimes the adjacent surface is somewhat flattened. 



Measurements. Length, 3.0-3.4 mm.; width, 1.0-1.4 mm. 



Type locality. Goldfield, Esmeralda County, Nevada. 



Holotype, male, and allotype, female, in my own collection. Col- 

 lected by Mr. F. W. Nunenmacher, who also possesses paratypes. 

 Obtained by beating. 



Remarks. By the heavy submarginal line and the pubescence not 

 being intermingled with longer erect hairs and black legs, it is related to 

 'nitens Casey. In nit ens however, the pronotal sides are much more 

 evenly arcuate and not constricted and emarginate behind the apical 

 angles. 



Dasytes angulatus, new species. Form elongate ovate, wider pos- 

 teriorly, somewhat depressed. Color black, sometimes brownish, moder- 

 ately shining ; mouth parts more or less pale, tibiae and tarsi pale rufous 

 or rufo-piceous. 



Pubescence brown to grayish-brown, short, decumbent and sparse ; 

 pronotal and elytral fimbriae very short and somewhat blackish, on the 

 former somewhat erect, on the latter a little longer and paler at apex. 



Head about as wide as the pronotal apex ; front feebly convex, im- 

 pressions feeble, rather long and separated by a median and very slight 

 longitudinal convexity ; surface finely, sparsely punctate and micro- 

 scopically reticulate. 



Pronotum about a fourth wider than long; sides scarcely arcuate, 

 rather broadly sinuate behind the angles, convergent from base to apex 

 as viewed from above, or feebly arcuate at middle, straight and converging 

 anteriorly, converging to base in basal fourth as viewed obliquely from 

 the side ; apex rather broadly emarginate ; apical angles blunt and sub- 

 rectangular ; base broadly arcuate, distinctly sinuate within the angles, 

 these are subacute and more or less minutely prominent ; disk with a dis- 

 tinct submarginal line that is somewhat abbreviated anteriorly and 

 passing arcuately into the basal submarginal groove, surface declivous 

 laterally, feebly impressed before and within the basal angles so that the 

 intervening surface appears oblique and more or less gable-like toward 

 the impressed line at basal fourth ; central area very feebly and sparsely 

 punctate, laterally microscopically reticulato-asperate. 



Elytra about twice as long as the width at base; sides moderately 

 divergent to basal third, thence broadly and evenly arcuate to apex;
