the series generally accompanied by impressed lines and composed 

 of very minute punctures, which, near the sides, become narrowly 

 sublunate as in irregularis. Length 1.7-2.0 mm.; width 0.9-1.1 mm. 

 British Columbia (locality unrecorded and at Kamloops). Shoal- 

 water Bay, Oregon LeConte. Five specimens rufipes Lee. 



17 Color very pale flavo-testaceous throughout. Head half as wide as 

 the prothorax, the punctures minute and rather diffuse, excessively 

 shallow; antennae of the usual type, well developed; prothorax evi- 

 dently more than twice as wide as long, the strongly converging 

 sides evenly and moderately arcuate, the basal bead evident; scu- 

 tellum ogival, moderately transverse, in great part covered with 

 feeble and transversely wavy strigilation; elytra distinctly elongate, 

 an almost even parabola in outline throughout, the entire surface, 

 except basally, with an exceedingly close minute strigiliform reticu- 

 lation, the punctures of the series minute, becoming larger and some- 

 what crescentic near the sides; metasternal process moderate, the 

 mesosternum distinct at its sides anteriorly and narrowly about the 

 apex. Length 2.0-2.2 mm.; width 1.1-1.2 mm. Arizona (near the 

 Grand Canon of the Colorado), T. Mitchell Prudden. Five 

 examples pruddeni n. sp. 



Color black to dark piceous, the under surface sometimes black 18 



18 Form moderately elongate, generally dark or blackish picous, the 

 under surface piceous, the legs pale, the femora sometimes infuscate; 

 head rather more than half as wide as the prothorax, the punctures- 

 sparse and very minute but clearly denned, the antennae as usual; pro- 

 thorax much more than twice as wide as long, the converging sides dis- 

 tinctly arcuate, the surface sometimes a little paler laterally but not 

 distinctly, the basal bead moderate, often feebler medially; scutellum 

 nearly twice as wide as long, ogival, with a few transverse strigila- 

 tions; elytra long, three times as long as the prothorax, more or less- 

 narrowly parabolic, rather sharply so in the male, the punctures- 

 minute, a little larger and feebly sublunate in the two lateral series, 

 the series generally accompanied by feebly impressed lines. Male 

 relatively very rare, much smaller than the female. Length (i cf, 

 14 9 ) 1.7-2.2 mm.; width 0.75-1.2 mm. Southern California, 

 Arizona (Walnut) and New Mexico (Albuquerque), H. F. Wick-

Form elongate, gradually obtusely attenuate behind, the apex obtusely 

 rounded; color very deep black above and throughout beneath, the 

 legs piceous-black, paler distally, the antennae pale; head fully half 

 as wide as the prothorax, the punctures minute and remote though 

 clearly denned; antennae rather long, the club subparallel, its three 

 joints of almost equal width; prothorax more than twice as wide as 

 long, the sides only moderately converging but distinctly arcuate, 

 the basal bead distinct; scutellum transverse, ogival; elytra much 

 elongated, fully three times as long as the prothorax, dull in lustre, 

 polished basally, covered for the most part with minute and exceed- 

 ingly dense strigiliform reticulation, the series accompanied by feebly 

 impressed lines and having the punctures minute and subaciculate,
