04 OTIORHYNCHID^. 



[Horn. 



A. cinerarius, n. sp. 



Oblong oval, densely covered with uniformly coloi'ed cinereous scales. 

 Rostrum and head longer than the thorax, sparsely punctured. Antennae 

 rufoiis, sparsely hairy. Thorax cylindrical, slightly wider than long, apex 

 truncate and slightly narrower than the base, sides feebly arcuate, surface 

 sparsely punctured. Elytra oval, slightly oblong, striate, strine coarsely 

 and rather closely punctured, intervals flat, densely scaly and with short, 

 semi-erect scale-like hairs. Body beneath very sparsely clothed witli short 

 hairs. Legs rufous, very sparsely scaly and pubescent. Length .14-. 18 

 inch; 3.5-4.5 mm. 



A rather inconspicuous insect resembling the preceding in form but more 

 elongate. In some specimens, probably males, the elytral intervals are 

 slightly alternating in Avidth. 



Collected by Mr. G. R. Crotch in the Sierra Nevada Mountains of Cali- 

 fornia, near Lakes Tahoe and Donner. 



A, deciduus, n. sp. 



Form oblong, piceous, moderately densely clothed with scales of pearly 

 lustre. Head and rostrum slightly longer than the thorax, densely scaly 

 and sparsely punctured, with short, pale, ei'ect hairs sparsely placed. An- 

 tennae piceous. Thorax broader than long, cylindrical, sides feebly arcuate, 

 disc moderately convex, surface sparsely punctured and slightly rugulose 

 and sparsely covered with pearly scales and erect pubescence. Elytra 

 oblong oval, obsoletely striate, strife with moderately coarse and close 

 punctures, intervals flat, not densely scaly and each with two rows of 

 moderately long erect pale hairs. Body beneath black, sparsely scaly and 

 hairy. Legs sparsely scaly and hairy, piceous. Length .16 inch ; 4 mm. 



Of the same form as the preceding, and somewhat recalling the form of 

 Scythropus. Differs from cinerarius by the pearly scales less densely 

 placed and more deciduous and by the much longer hairs covering the 

 surface. 



Collected at San Francisco.
