slightly behind the middle, the club small, subglabrous and slender, gradually 

 formed, its basal segment half the mass; prosternum excavated, the sides of 

 the depression ridge-like, becoming angulate posteriorly — at least in the 

 male; prothorax elongate, not tubulate at apex. [Type I. sparsa nov.] 



lops 



Body narrow but ventricose, coarsely and densely sculptured; beak short, thick, 

 strongly sculptured, not separated by an impression; antennae short, medial, 

 the club well developed, oval; prosternum nearly flat; prothorax shorter, 

 not tubulate; elytra coarsely and closely sulcate; vestiture sparse. [Type 

 A . sculpturata nov.] Aniops 



28 — Body very slender and elongate, with relatively small, constricted and 

 subtubulate prothorax, which is rather finely sculptured and subglabrous; 

 beak very slender, cylindric, truncate at tip, the mandibles very small, 

 almost hidden when closed; antennae slender, submedial, the first funicular 

 joint thick, 2-7 very narrow, the second slender, rather longer than the first; 

 club small, oval and subglabrous, with long basal segment; prosternum short 

 and broadly concave before the coxae; elytra very elongate, deeply striate. 

 [Type M. parvicollis nov.] Macriops 



29 — Body narrow, more or less opaque, closely sculptured and with minute 

 sparse setiform squamules, the elytra striato-punctate, with finely carinulate 

 intervals; beak rather short, thick and closely sculptured, not separated by 

 an impression, the antennae somewhat short, submedial, the first funicular 

 joint very much broader and longer than the next two combined, 2-7 grad- 

 ually broader, more or less compactly joined, the club moderate, narrowly 

 oval, its basal segment half the mass; prosternum not much modified, the 

 coxae narrowly or moderately separated; tarsal claws minute, very slender, 

 approximate but not connate. [Type P. carinulosa nov.] Psiona 



The last four genera are founded upon very small, narrow species 

 of peculiar facies, few in number and apparently rare individually; 

 as in the case of several others of this tribe, they are probably of 

 decidedly secluded habits. 



Chepagra n. gen. 



Although associable with the Nicentrid series, this genus has a 

 peculiar facies due to its parallel convex form, strongly convex 

 surface and rather inflated, laterally rounded prothorax. The beak 

 is moderate in length and thickness, slightly compressed and 

 strongly sculptured basally, feebly arcuate, somewhat more so 

 basally, and is not separated from the head by any trace of im- 

 pression, the antennae just visibly beyond the middle. The anterior 

 coxae are large and narrowly separated, and the unchanneled 

 prosternum has a very small feeble apical fossa, laterally inclosed 

 by slight ridges. The tarsi are not very wide and the claws are 

 strongly arcuate and diverging. The type may be described as 

 follows : 



Chepagra rotundicollis n. sp. — Parallel, convex, dark rufous, the prothorax 

 blackish; pronotum at the sides and apex with long close whitish scales, the 

 elytra with similar scales, moderately close and confused, but smaller and forming 

 single interstitial lines toward the sides; under surface throughout with close
