54 OTIORHYNCHID.^.. [Horn. 



within, articular surface of hind tibitxj cavernous, tarsi normal, (third joint 

 broadly bilobed) densely pubescent beneath. Surface densely scaly and 

 with small granules. 



This genus, as suggested by Dr. LeConte, should probably be referred 

 to Lacordaire's group PhytoscapJiides, but if so, I feel entirely unwilling 

 to separate that group from the present, the scrobes of the genera here in- 

 cluded showing a very gradual transition in form.

Elongate oval, black, surfiice densely covered with cinereous scales, with 

 cupreous and pearly lustre at the sides, disc of thorax and elytra slightly 

 brownish. Head and rostrum longer than the thorax, punctured and mode- 

 rately densely scaly, sparsely setulose, rostrum with finely elevated median 

 line terminating in a slight impression. Scape with scale-like hairs. Thorax 

 cylindrical, as broad as long, apex and base truncate, sides arcuate, more 

 strongly in front of middle, disc moderately convex and with median sulcus, 

 surface with moderately large granules, each punctured and with a short 

 stout seta, median line and narrow space each side not granulate, inter- 

 granular spaces densely scaly, scales darker on the disc, pearly and cupre- 

 ous at the sides. Elytra regularly oval, very suddenly declivous posteriorly, 

 sutural region more prominent at declivity, disc feebly convex, striae obso- 

 lete, and with rows of indistinct punctures, each alternate interval with 

 two indistinct rows of moderate granules, each punctured and bearing a 

 short, stout, curved, black seta, interspaces densely scaly, scales darker on 

 the disc, pearly and cupreous at the sides. Body beneath and legs mode- 

 rately densely scaly, sparsely setulose, scales pearly and cupreous. Length 

 .32-. 40 inch ; 8-10 mm. 



This species has a marked resemblance to Tyloderes chrysops in size, 

 sculpture and general aspect. 



Occurs in California and Oregon.

Rostrum oblique, longer and narrower than the head, without transverse 

 basal impression, above tlattened, base quadrangular, apex dilated, alse 

 moderately prominent, tip feebly emarginate and with small smooth space. 

 Scrobes veiy feebly arcuate, deep in front, very rapidly evanescent pos- 

 teriorly, directed toward the lower margin of the eye. Antennae moderate, 

 scape very slightly passing the anterior margin of the eye, feebly stouter at 

 tip ; fuuicle 7-jointed, joints 1-2 longer and equal, 3-7 gradually shorter, 

 oboonical ; club oval. Eyes oval. Thorax oval, broader than long, apex 

 and base truncate, lobes moderate. Scutellum very small. Elytra oval, base 

 very feebly emarginate, apex declivous. Metasternum short, side pieces 

 indistinct, sutures entirely obliterated, intercoxal process moderate, trun- 

 cate, second segment as long as the two following united, first suture arcu- 

 ate. Tibiae mucronate at tip, articular surfaces of hind tibiae cavernous, 

 tarsi normal. Surface densely scaly and with very short setae.
