OPHRYASTINI. 51 



piceous, with sparsely placed scale-like hairs, intercoxal process and last 

 ventral segment densely cribrate punctate. Legs sparsely scaly and 

 pubescent. Length .26 inch ; 6.5 mm. 



Although very different in appearance from the preceding species, there 

 is some difficulty in finding characters expressible in words to separate the 

 two. The thorax of the present species is relatively much broader and at 

 its widest part but little narrower than the elytra. The alternation of eleva- 

 tion of the intervals is very little marked on the disc and is but slightly 

 more evident near the declivity. 



A variety ? occurs in Oregon with intervals nearly flat and similar. 



Occurs in Oregon and Vancouver. 



A. virsina, n. sp. 



Form oblong oval, surface densely covered with brownish scales and 

 with rather long, pale-brown erect hairs. Head and rostrum as long as the 

 thorax, rostrum not subcarinate above, surface punctured, densely covered 

 with brownish scales becoming cinereous at the sides and beneath and 

 with moderately long erect hairs. Thorax not wider than long, apex and 

 base equal and truncate, sides evenly arcuate, lobes very short ; disc mode- 

 rately convex, not granulate, finely punctured, densely covered with 

 brownish scales with slightly pearly lustre, and paler at the sides and with 

 long erect hairs. Elytra oval, verj' slightly wider at middle than the 

 thorax, base feebly conjointly emarginate, humeri rectangular, sides mode- 

 rately arcuate, apex gradually declivous, disc moderately convex, striate, 

 stria? with rather coarse punctures closely placed, intervals slightly convex, 

 densely covered with brownish scales and with two rows of closely placed 

 and rather long, pale brownish hairs. Body beneath and legs sparsely 

 scaly, scales slightly silvery, and with moderately long hairs. Abdomen 

 sparsely punctured. Length ,28 inch ; 7 mm. 



One specimen (J^, Oregon. 



A. rauca, n. sp. 



Oblong, surface densely covered with brownish scales, and Avith mode- 

 rately long, pale-brownish liairs. Head and rostrum as long as the thorax, 

 densely cribrate punctate, rostrum subcarinate, surface sparsely scaly and 

 hairy. Thorax nearly globose, slightly wider than long, apex truncate, 

 base slightly arcuate, sides strongly arcuate, lobes very feeble, disc convex, 

 moderately densely granulate, granules punctured at summit, surface 

 sparsely scaly and hairy. Elytra oblong, scarcely wider at middle than the 

 thorax, base feebly emarginate, humeri rectangular, disc moderately con- 

 vex, obsoletely broadly striate, strife with large, deeply impressed, rather 

 closely placed punctures, intervals fiat, densely covered with brownish 

 scales and moderate hairs placed in two rows on each interval. Body 

 beneath densely and coarsely punctured and with very few short hairs 

 Legs sparsely scaly and hairy, hairs longer than on the bodJ^ Length 

 ,22 inch ; 5.5 mm. 



Differs from the preceding in sculpture and by the much shorter hairs of 

 the upper surface. 



Two specimens, San Francisco, Cal.
