260 AMERICAN COLEOPTERA. 



OTIORHYNCHID^. 



Opliiwaxites Myiniiietrious n. sp. — Elongate-oval, strongly convex, 

 densely clothed with cinereous, ochieous and dark brown scales and with abund- 

 ant erect short brownish pointed setfe. Beak evidently longer than wide, mod- 

 erately dilated at apex, separated from the front by an evident though not strong 

 transverse impression ; upper surface trisulcate, median sulcus broader and with 

 a central carina; lateral sulci shorter, broader behind and not very well limited 

 externally. Antennje cinereous, club piceous; first six funicular joints longer 

 than wide, the outer ones only slightly so, seventh joint as wide as long, basal 

 joint shorter than the next two together; front moderately convex, with an 

 elongate median fovea. Prothorax five-eighths wider than long, widest just 

 before the middle, sides moderately nearly evenly arcuate, not tuberculate; 

 apical constriction feeble, basal constriction wanting; surface broadly uniformly 

 convex, deeply, rather coarsely, unevenly punctate. Elytra oval, nearly two- 

 fifths wider than the thorax and one-half longer than wide, sides broadly evenly 

 arcuate, base truncate, the angles nearly right, but small and only very slightly 

 prominent; striaj fine, the punctures scarcel.v detectable; interspaces nearly flat, 

 but alternately a little more convex. Beneath densely scaly as above, the scales 

 in great part cinereous, but minged with ochreous at the base of the abdomen 

 and on the sternal side pieces; setfe paler, finer and more inclined than above. 

 Legs slender, tarsi narrow, all the joints elongate, the basal joint of hind tarsi 

 more than twice as long as wide and shorter than the next two combined ; third 

 joint emarginate rather deeply but not at all wider than the second ; first three 

 joints beneath concave, glabrous at middle, densely pilose at sides ; terminal joint 

 scaly and setose. Length 10.5 mm. ; width 4 mm. 



Santa Fe (Fenyes), one example. The maculation of this species 

 is more distinct and symmetrical than usual in this genus, and is as 

 follows : head with a median vertical vitta of dark brown ; a wider 

 stripe of the same color through the eye, continued in a sharply 

 defined prothoracic vitta; middle third of the prothorax cinereous, 

 sides beyond the brown vitta cinereous, flanks with an ochreous 

 stripe. Interspaces 1-3-5, etc., ochreous ; 2-4-6, etc., cinereous, 

 each with a double row of elongate dark brown spots. The tarsal 

 structure of this species is so different from that of any of our other 

 Ophryastes as to perhaps exclude it from this genus; as remarked 

 by Horn, however, there is some variation in this respect among our 

 older species. Otiier characters separating symmetricus from previ- 

 ously described species are : the median rostral carina, more abund- 

 ant and more erect setse, lack of lateral thoracic tuberosities and 

 slightly arcuate first ventral suture. 



The establishment of Eupagoderes by Horn for certain species 

 previously referred to Ophryastes has not proved satisfactory, all 

 the characters named being gradatioual. The most conspicuous of 

 these, taking the species as a whole, is the presence of lateral callosi-
