56 OTIORHYXCHIDJE. 



[Horn. 



with very slight transverse impression, front slightly more convex, alee 

 moderately prominent. Scrobes moderately deep, short, arcuate and di- 

 rected rather rapidly inferiorly. Antennae moderate, sub-apical, scape cla- 

 vate, passing slightly the anterior margin of the eye ; funicle 7-jointed, 

 joints 1-2 longer, the first longer than the second, 3-7 short, broader than 

 long, the last very close to the club and broader ; club oval. Eyes oval, 

 slightly pointed beneath. Thorax cylindrical, broader than long, apex and 

 base truncate, sides moderately arcuate, lobes feeble, distinctly timbriate. 

 Scutellum invisible. Elytra regularly oval. Humeri rounded. Meta- 

 sternum short, side pieces narrow, suture distinct. Intercoxal process 

 moderate, arcuate in front ; second segment of abdomen as long as the two 

 following united, first suture strongly arcuate at middle. Anterior tibiae 

 alone mucronate, articular surfaces of hind tibiae feebly cavernous. Tarsi 

 setose beneath, third joint not broader than the second and very feebly 

 emarginate. Claws free. Surface scaly and hairy. 



The unique species on which the above genus is founded, resembles in 

 general aspect certain elongate males of Trigonoscuta pilosa. The genus 

 by the form of its tarsi and the seventh joint of funicle, approaches Eupa- 

 goderes of the group Ophryastes, differing however in the structure of the 

 abdomen and metasternal side pieces. 



C. pauper, n. sp. 



Oblong oval, piceous, densely covered with pale brow r nish scales sparsely 

 variegated with cinereous and with erect hairs. Head and rostrum as long 

 as the thorax, moderately densely covered with pale brownish and cinere- 

 ous scales intermixed and sparsely hairy, rostrum feebly canaliculate. 

 Thorax cylindrical, slightly broader than long, apex and base truncate, 

 sides moderately arcuate, disc convex, densely scaly and sparsely hairy. 

 Elytra oval, finely striate, striae indistinctly punctured except at the sides, 

 intervals flat, densely scaly, each with two rows of moderately long yel- 

 lowish hairs. Body beneath and legs much less densely scaly than above, 

 sparsely hirsute. Length .24 inch ; 6 mm. 



This species is of the form and size of Peritelus griseus of Europe, and 

 resembles it somewhat in vestiture. 



One specimen, Dacota. 



Group IV. Pbyxeles. 



Rostrum slightly narrower than the head, alae not prominent. Scrobes 

 superior, badly defined, feebly arcuate, rapidly evanescent posteriorly and 

 not attaining the eyes. Second segment of the abdomen longer than the 

 two following united, separated from the first by a straight* suture. 



The validity of the separation of this as a distinct group in our fauna 

 seems somewhat doubtful, the only character by means of which it may be 

 distinguished from the preceding group is found in the position of the 



* Lacordaire says arcuate. It really appears so when the scales and crust re- 

 main, but when these are removed the suture will be found as stated.
