20 OTJORHYNCHID^:. 



[Horn. 



base arcuate; median line distinct, surface coarsely punctured and irregular, 

 densely clothed with cinereous scales. Elytra broadly oval, A^ery curved, 

 slightly broader at base than the thorax, indistinctly striate, striee with 

 moderately coarse punctures, intervals alternately more convex, subcosti- 

 form, surface densely scaly, scales cinereous Avith a narrow triangular basal 

 space, submedian and subapical transverse bisinuous fascia of darker color. 

 Body beneath coarsely but sparsely punctured, densely scaly. Legs 

 densely scaly. Tarsi glabrous beneath. Length .28-38 inch ; 7-10 mm. 



This species has the same style of coloration as is seen in Epicmms, but 

 the darker elytral fascite are at times absent. 



Occurs in Kansas and Texas, and is not rare. 



EPICURUS Sch. 



Epicmrus Schonherr, Gen. Cure, ii, p. 323. 



Rostrum as long or slightly longer than the head, and nearly as broad, 

 parallel, feebly canaliculate along the middle, tip feebly emarginate and 

 with a triangular smooth space limited bj^ an arcuate groove. Scrobes 

 moderately deep, well defined, passing immediately beneath the eye, and 

 moderately arcuate. Eyes slightly longitudinallj'^ oval. Antennae mode- 

 rately long, scape gradually clavate, attaining nearly the middle of the eye; 

 funicle 7-jointed, joints obconical, 1-2 moderately elongate, 3-4-5 nearly 

 equal, 6-7 very slightly longer than last, not close to the mass which is 

 elongate oval. Thorax variable, conical or cylindrical and narrowed in 

 front. Scutellum very small. Elytra oval, broadly but feebly emarginate 

 at base. Legs moderate. Tarsi spongy pubescent beneath. Body pyri- 

 form or elongate, densely scaly. Cotyloid cavities of hind tibiae internal, 

 glabrous, tip of tibiae truncate. First suture of abdomen arcuate at 

 middle. 



Two species of Epica^rus occur in our fauna. 



Thorax not wider at base than at middle, form more 

 or less elongate, narrowed at middle imbrieatus. 



Thorax conical widest at base, body pyriform formidolosus.

Form variable. Rostrum feebly sulcate at middle and with a slight pre- 

 ocular impression, surface sparsely punctured densely scaly. Vertex with 

 impressed puncture. Thorax cylindrical narrowed at anterior third, sur- 

 face with deeply impressed punctures in great part concealed by densely 

 placed scales, cinereous along the middle, darker at the sides. Elytra not 

 striate but (when denuded) with rows of large deep punctures, surface 

 densely scaly, color cinereous, with basal space, submedian irregular, and 

 subapical sinuous fascia? darker in color. Body beneath and legs densely 

 scaly, scales nearly white. Length .30-. 46 inch ; 7.5-11.5 mm. 



This species occurs in every portion of our territory east of the Rocky 

 Mountains and south and west of Pennsylvania, and exhibits a very great 

 ■variation in form and coloration. The elytra may be elongate oval or
