Coleopterological Notices, III. 145 



I. iowensis n. sp. — Almost evenly elliptical, convex, pale brownish- 

 piceous, the head and prothorax slightly more rufo- ferruginous ; surface 

 shining, the pubescence very short and somewhat sparse. Head very densely 

 and somewhat coarsely punctate, the front broadly, strongly impressed ; eyes 

 very large ; antennae slender, filiform, three-fifths as long as the body. Pro- 

 thorax four-fifths wider than long; sides feebly convergent from the base, more 

 strongly so and broadly rounded anteriorly ; apex feebly arcuate, two-thirds 

 as wide as the base, the latter transverse and nearly straight ; basal angles 

 right ; disk punctured like the head, the punctures unusually coarse, deep 

 and distinct, nearly in mutual contact ; basal foveae very feeble, transverse, 

 on the posterior convexity and bordering the edge. Elytra nearly four times 

 as long as the prothorax, and, at the middle, about one-half wider ; disk 

 finely and rather sparsely punctate, the feeble impressed lines quite distinctly 

 visible by reflected light throughout the width, the two sutural strong toward 

 apex. Under surface polished ; abdomen minutely and sparsely punctate ; 

 metasternum rather coarsely and sparsely so, with an unusually large ini- 

 punctate area in front of the transverse groove. Legs long and very slender, 

 the hind tarsi nearly as in sericea. 



Male. — Eyes separated by scarcely one-fourth more than their own width ; 

 third joint of the antennae two-thirds as long as the fourth. 



Length 5.2 mm. ; width 2.2 mm. 



Iowa. 



The single specimen before me seems to be slightly immature. 

 The maxillary palpi are nearly as in sericea, but with the inner 

 angle of the terminal joint rather more broadly rounded. 



This is a rather isolated species, at once distinguishable by its 

 large eyes, strongly impressed front, sparse punctuation and antennal 

 structure. 



1. discolor n . sp. — Elongate-elliptical, moderately convex, rather strongly 

 shining, piceous-black, the antennae and legs throughout concolorous ; pro- 

 notnm and presternum pale ferruginous ; pubescence fine, very short, sparse. 

 Head feebly convex, closely, rather coarsely punctate, with a small elongate 

 impression in the middle and just behind the epistoma ; eyes rather small ; 

 antennae filiform, fully two-thirds as long as the body. Prothorax about two- 

 thirds wider than long, the apex truncate, two-thirds as wide as the base, the 

 latter truncate, the lateral sinuations almost invisible ; basal angles right, not 

 appreciably rounded ; sides broadly, almost evenly rounded, nearly straight 

 and parallel toward base ; disk rather coarsely, very closely punctured, the 

 interspaces shining ; basal foveae small, rounded, distinct. Elytra a little more 

 than three times as long as the prothorax, and, in the middle, about one-third 

 wider, moderately narrowly rounded at apex ; disk finely but deeply and 

 distinctly, rather sparsely punctate, polished, without trace of impressed striae 

 except the two satural, which are feebly visible toward the apex. Under 

 surface polished, finely and very sparsely punctate except the prosternum,
