Eyes moderate in size and relatively less prominent, nearly half as long as the head. .28 



2S — Nodes of the apical angles well developed and longitudinally convex, but little 

 shorter than the distance thence to the spicules ; antennal club unusually long 

 and narrow, the last joint longer than wide ; body rather large, narrowly elongate- 

 oval, rather dark rufo-testaceous throughout, the pubescence somewhat short and 

 moderately abundant but with the subserial setee quite long and obvious ; pro- 

 thorax moderately transverse, densely and deeply punctured, the callous spots 

 small but rather distinct, the lateral spicules small ; elytra unusually elongate, 

 rather acutely ogival at apex, distinctly less elongate in the male, quite coarsely 

 and deeply but not very closely punctured. Length 2.6-2.8 mm. ; width 1. 05 

 mm. Utah (southwestern) — Mr. Weidt histricus, sp. nov. 



Nodes of the apical angles small, very much shorter than the distance separating 

 them from the spicules 29 



29 — Pubescence moderate in length and subdecumbent, the punctuation rather fine ; 

 body oblong, shining, dark testaceous throughout ; prothorax well developed, 

 moderately transverse, but little narrower than the elytra, the apical nodes ex- 

 tremely small, feeble, very oblique, narrow and convex sublaterally, with a 

 minute posterior spicule ; submedian spicule very minute, slightly behind the 

 middle and separated from the nodes by between two and three times the length 

 of the latter, punctures small but deep, moderately close-set, the callous spots 

 small and rather feeble but distinct ; elytra oval, rather obtusely rounded at tip, 

 three-fifths longer than wide, the punctures rather fine but deep and not very close- 

 set ( J ). Length 2.2 mm. ; width 0.9 mm. Indiana; [Carolina — Zimm.] 



fungicola Zimm. 



Pubescence long and bristling, the body coarsely punctured. Sonoran regions 30 



30 — Lateral spicules of the prothorax distinct and moderately large, the sides behind 

 them thickened and laterally subprominent half the distance to the base, then 

 sinuate to the angles ; body rather stout, oval, convex, polished, piceous in color, 

 the elytra blackish, nubilously paler at apex ; prothorax moderately transverse, 

 very coarsely, closely punctate, uneven, the callous spots large, conspicuous and 

 unusually approximate longitudinally ; apical nodes very oblique, spiculate be- 

 hind ; elytra oval, distinctly arcuate at the sides, moderately obtuse at apex, 

 scarcely more than one-half longer than wide, and, at the middle, slightly wider 

 than the prothorax, the punctures very coarse, deep and somewhat sparse, as 

 usual very small toward tip ( 9 ). Length 2. 1 mm. ; width 0.9 mm. Arizona 

 ( Tucson ) discedens , sp. nov . 



Lateral spicules extremely minute and sometimes apparently obsolete, the sides be. 

 hind them arcuately converging, sometimes sinuate very near the angles, in 

 which case the latter are acutely prominent 31 



31 — Narrowly oblong-oval, testaceous, the elytra frequently infuscate ; prothorax 

 rather short and transverse and slightly narrower than the elytra in both sexes, 

 the punctures moderately coarse, deep and somewhat close-set, the callous spots 

 large and normally placed, the lateral edges rather widely reflexed ; sides 

 strongly convergent behind the middle ; elytra more than three times as long as 

 the prothorax in the female, much shorter in the male, rather narrowly obtuse 

 behind, very coarsely, but only moderately closely, punctate. Length 1.9-2.0 

 mm. ; width o. 7S mm. Utah (southwestern) — Mr. Weidt.
