terior angles thickened and decidedly prominent, the punctures 

 moderately small and well separated, deep, becoming rather coarse 

 and separat/sd by barely their own widths laterally ; elytra strongly 

 inflated, oval, two-fifths longer than wide, with scarcely im- 

 pressed series of very coarse, deep, moderately close-set punctures, 

 disappearing at about apical fourth, the interstitial punctures 

 minute, sparse and inconspicuous ; abdomen minutely, sparsely 

 punctured, the basal segment becoming coarsely punctured only 

 near the coxffi. Length S. 5 mm. ; width 3. 75 mm. (?). Texas.

15 — Body very stout, deep black, the legs rufo-piceous, the anterior 



parts alutaceous, the entire elytra deeply opaque, head much nar- 

 rower than the ])rothorax, smooth, minutely, sparsely punctate, 

 with very fine and feeble vugse near the carinje, the umbo very 

 large and conspicuous ; antenniE moderate, the tenth joint fully 

 as wide as long; prothorax transverse, fully three-fifths wider than 

 long, the sides rounded, becoming strongly convergent and sinuate 

 in only about basal third, the apical angles thickened and very 

 prominent, the punctures fine and moderately separated, becom- 

 ing moderately coarse and separated by scarcely more than their 

 own widths laterally; elytra very inflated and convex, barely a 

 fourth longer than wide, the unimpressed series composed of 

 moderately coarse, deep and rather widely spaced punctures, con- 

 tinuing to apical fourth or fifth ; abdomen dull, minutely, sparsely 

 punctate, the first segment coarsely punctured medially along each 

 side of the median line, except toward apex. Length 7.S mm. ; 

 width 3.6 mm. (9). Texas nodiceps Lee. 



16 — Form stout, convex, deep black, the legs and antennse more or 



less rufo-piceous, almost glabrous, each puncture with a minute 

 hair, feebly alutaceous, the entire elytra with dull lustre; head 

 smooth, minutely, sparsely punctate, with the umbo large and 

 prominent, the surface without plicae near the strong orbital 

 carinas ; prothorax much wider than the head, transverse, three- 

 fifths wider than long, the sides inflated, strongly and arcuately 

 converging in basal half, becoming sinuate basally, the anterior 

 angles thickened, acute and very prominent; surface widest at 

 the middle, strongly, closely punctate, very coarsely and more 

 closely so laterally, the punctures mingled everywhere with 

 smaller distinct punctures, rendering the sculpture rather dense 

 throughout; elytra strongly inflated and convex, oval, about two- 

 fifths longer than wide, with unimpressed series of only moder- 

 ately coarse, widely separated punctures, becoming gradually 

 smaller and disappearing between apical third and fourth, the 

 sparse interstitial punctures extremely minute and scarcely visible ; 

 abdomen finely, sparsely punctured, with some coarse punctures 

 on the first segment, where the fusco-pubescent male fovea is un- 

 usually small, unimpressed and elongate-oval. Length 6.7 mm. ; 

 width 3.25 mm. (c^). Texas (Laredo), — H. F. Wickham.
