provoensis n. sp. 



Head large, only just visibly narrower than the prothorax; form less 

 parallel, moderately convex, pale testaceous throughout, the elytra 

 each with a small piceous cloud near the suture posteriorly, the 

 under surface of the hind body partially variegated with piceous; 

 head smooth, convex, the eyes notably large and very prominent; 

 antennae slender, fusco-testaceous, clearer basally; prothorax scarcely 

 a third wider than long, the sides subevenly rounded, only a little 

 less so posteriorly, the basal angles very obtuse, clearly defined and 

 evidently prominent at their apices; base distinctly oblique at the 

 sides and but little narrower than the truncate apex; surface smooth, 

 the foveae small, feeble, the punctures fine, not dense and covering 

 but a small area, the stria distinct, subentire; elytra less than one- 

 half longer than wide and more than one-half wider than the pro- 

 thorax, the striae feebly impressed, the intervals not very convex 

 even suturally; discal puncture at two-thirds. Length (9) 2.5 

 mm.; width 0.9 mm. Texas (El Paso). A single specimen, taken 

 by the writer larvatus n. sp. 



26 Body very small in size. Elongate, black, shining, head smooth, the 

 frontal impressions oblique, deep; palpi pale; antennae obscure, the 

 two basal joints pallid; prothorax not shorter than wide, barely 

 emarginate anteriorly, the base feebly rounded, slightly narrowed 

 posteriorly, the sides moderately rounded, the hind angles feebly 

 explanate, broadly rounded; transverse impressions indistinct, the 

 stria deep, entire, the foveae broad, rounded, not deep, confused with 

 the explanate angles, obsoletely and sparsely punctate; elytra 

 parallel, the apex rounded, not sinuate, deeply striate, the intervals 

 feebly convex, the third unipunctate; scutellar stria wanting; legs 

 rufo-testaceous, the posterior rufo-piceous, the femora more obscure. 

 Length 3.0 mm.; width 1.25 mm. Island of Mackinaw. One 

 specimen. [Geobccnus neglectiis Lee.] neglectus Lee. 



Body much larger, more southern in habitat 27 



27 Form moderately slender and convex, shining, clear testaceous in 

 color, the head piceous, the elytra slightly obscure toward the suture, 

 the latter pale; under surface of the hind body blackish-piceous, the 

 epipleura and legs pale testaceous; head fully three-fourths as wide 

 as the prothorax, the eyes moderate in size but very prominent; 

 antennae very slender, nearly half as long as the body, fusco-tes- 

 taceous, gradually clearer basally; prothorax only just visibly wider 

 than long, the sides broadly, almost evenly rounded, widest before 

 the middle; base transverse medially, the angles very broadly 

 rounded; apex feebly sinuate, but little wider than the base and 

 with rather blunt angles; surface very evenly, moderately convex, the 

 stria deep and entire, the foveae rather small, rounded, feeble and with 

 a few fine punctures; the foveae are isolated and distinct and the 

 basal angles are not deplanate; elytra rather more than one-half 

 longer than wide, only two-fifths wider than the prothorax, parallel, 

 with feebly arcuate sides and evenly rounded apex; striae fine but
