the sides, each puncture with a small but very distinct pale 

 hair; elytra two-fifths to one-half longer than wide, fully one-half 

 wider than the prothorax, oval, rapidly obtuse behind, the apical 

 lobe very short and obtuse; surface with the costse narrow and sharply 

 though moderately elevated, the side margins also elevated, the 

 intervals nearly flat, undulato-rugose, densely opaque, the fine 

 seta-bearing punctures strongly granulate; portion between the 

 second costse, across the suture, flat to very moderately convex; 

 abdomen sparsely, asperulately punctate, the small pale hairs dis- 

 tinct. Length (c?) 15.5-17.0 mm. ; width 8.1-8.9 mm. New Mexico 



(Escondido), Wickham subpubescens n. sp. 



5 Discal costse of the elytra fine and abruptly elevated 6 



Discal costae broader, more obtuse and less elevated; prothorax very 



large 9 



6 Intervals between the elytral costae flat or nearly so, though rugose as 



usual, the elytra much narrowed basally, more oval 7 



Intervals concave., with the rugulosity still more pronounced; prothorax 

 larger, the elytra less narrowed basally, the costae more conspicu- 

 ously elevated 8 



7 Body stout, strongly convex, black to piceous in color, rather shining; 

 head strongly and closely punctate throughout, each puncture with 

 a very short dark fulvous hair; prothorax short, nearly twice as 

 wide as long, two-thirds to three-fourths as wide as the elytra, 

 unusually convex, with coarse confluent punctures leaving large 

 shining and very irregular punctureless patches, especially near the 

 sides posteriorly and along the basal margin, concave and evidently 

 reflexed with thin and scarcely at all serrulate edge laterally, the 

 punctures with their anterior margins acutely crenulate, each bearing 

 a short subfulvous hair; sides rounded; basal angles acute, not 

 everted; elytra from a third (cf), to a fourth (9 ), longer than wide, 

 widest somewhat behind the middle, the costse rather fine and not 

 strongly elevated, uniting on the posterior slope as usual, the flat 

 broad intervals confusedly and coarsely, subtransversely rugose 

 and with the minute granuliferous punctures close-set and con- 

 spicuous, each bearing an extremely minute erect hair; abdomen 

 rather shining, sparsely, moderately punctate, more closely medially, 

 the hairs very inconspicuous, dark fulvous. Length 19.0-20.0 mm.; 



width 10.0-11.2 mm. Kansas, F. H. Snow turgescens n. sp. 



A Form and sculpture nearly similar but much more inflated, black 

 or nearly so, the prothorax ( 9 ) less transverse, three-fourths 

 wider than long, fully two-thirds as wide as the elytra, similarly 

 sculptured but with the side margins much* more thickened and 

 abruptly narrowly though feebly reflexed from a distinct line at a 

 slight distance inside the edge, the converging sides basally feebly 

 and very broadly sinuate, the basal angles much prolonged pos- 

 teriorly and acute; elytra more inflated, widest at the middle, a 

 third longer than wide, the slender ridges higher, the interspaces 

 less flat, rugose, with the fine granuliferous punctures much sparser 

 though distinct, each with a longer and fulvous though very small
