sinuate basally, the angles right, sharp and very prominent; surface 

 smooth and impunctate throughout, the impressions obsolescent, 

 the stria fine, greatly biabbreviated ; foveae smooth, very deep, elon- 

 gate-oval, the carina very faint, subobsolete; elytra parallel, three- 

 fifths longer than wide, two-thirds wider than the prothorax, ob- 

 tusely ogival in about apical third; striae barely at all impressed, the 

 sixth obsolete behind about the middle, the seventh wholly wanting; 

 punctures moderate; foveae at two-fifths and two-thirds. Length 

 (9 ) 6.0 mm.; width 2.4 mm. New Mexico (somewhere on the road

badiipenne n. sp. 

 Body very moderately convex as in erosum; thoracic base always at 



least somewhat wider than the apex 27 



27 Elytra and upper surface deep bluish or greenish black throughout, 

 the neck sometimes faintly pallescent. Body oblong, highly pol- 

 ished throughout, black beneath, the legs pale rufous; head rather 

 small, not three-fourths as wide as the prothorax and very much 

 narrower than an elytron, with only moderately prominent eyes and 

 deep sulci; antennae long, slender, fuscous, pale basally; prothorax 

 two-fifths wider than long, the sides strongly rounded anteriorly, 

 long and oblique posteriorly, becoming sinuate only at the angles, 

 which are sharp and minutely prominent; surface smooth, the im- 

 pressions and stria nearly as in the preceding, the posterior impres- 

 sion feeble but evident, the deep foveae nearly similar but less abrupt 

 and slightly rugulose; elytra one-half longer than wide to somewhat 

 more, the parallel sides feebly arcuate, two-thirds wider than the 

 prothorax, convex, the striae rather coarse and deeply impressed, 

 strongly punctate, the seventh fine and obsolescent, sometimes feebly 

 traceable; foveas at two-fifths and two-thirds. Length (c/ 1 9 ) 6.4- 

 7.2 mm.; width 2.3-2.6 mm. New Mexico (Jemez Springs, Las 



Vegas and other parts of the Rio Grande Valley) lugubre Lee. 



A Similar to hignbre but broader, the prothorax only a fourth wider 

 than long, the oblong elytra longer, three-fifths longer than wide, 

 the striae more abbreviated, the sixth only visible to about the 

 middle, the seventh wanting. Length (cf 9 ) 6.5-7.1 mm.; width 

 2.3-2.8 mm. Arizona (Tucson). La Veta, Colo., and San Diego, 



Cal., LeConte stabile Lee. 



B Similar to lugubre but smaller and especially narrower, differing 

 also in the prothorax, which, though similarly transverse and 

 rounded laterally, has the posterior sinus of the sides much 

 stronger, the sides becoming parallel for a considerable distance 

 before the right and very sharp angles; elytral striae nearly simi- 

 lar but less impressed and with the punctures less close-set. 

 Length (o* 9 ) 6.2-6.5 mm.; width 2.2-2.4 mm. Arizona (prob- 

 ably near the southern boundary) vafrum n. subsp.
