1. Proiiotal tubercles plainly visible among the scales, the pronotal surface con- 



siderably roughened or rugose, with the median sulcus more or less devel- 

 oped; a feeble humeral swelling usually present (between origins of sixth 

 and ninth striae); pronotal scales striated; prevailing color cinereous or 

 cinereous mottled with brown (western North America)

Pronotal surface smootli and completely covered with appressed, in part 



nonstriated scales, the median sulcus wanting or faintly indicated; humeral 



swelling wanting 2. 



2. Length, 6.7 mm ; elytral intervals evidently, though rather feebly, convex ; 



elytral setae long (about as in acqnalis) ; prothorax wider than long, the 

 sides strongly rounded ($) [Placer County, Calif, (type locality]

PANSCOPUS (NEOPANSCOPUS) WICKHAMI, n. sp. 



Length, J* 4.4 mm; width, 1.7 mm. Body slender, subparallel, 

 densely scaly, the prothorax as long as broad ; color irregularly and 

 feebly variegated brown and cinereous, the scales in part somewhat 

 varnishlike in luster, especially on head, prothorax, and femora; 

 rostrum above densely scaly to apex, only the nasal plate bare, the 

 apical region faintly impressed ; surface sculpture of pronotum com- 

 pletely covered by an even coating of flat, closely appressed scales ; 

 elytral intervals nearly flat, each with an irregular row of rather fine, 

 short, pale brownish setae, the serial punctures quite widely spaced. 



Rostrum practically straight, a little more than twice as long as 

 thick, about five-sixths as long as prothorax, narrowest about middle, 

 gradtially and very feebly widened basally, abruptly and strongly so 

 toward apex, upper surface subcontinuous with front in profile, setae 

 above short, scales dense, no indication of carinae through the vesti- 

 ture. Eyes feebly convex, separated above by basal width of rostrum ; 

 no frontal fovea visible. Antennal scape setose and densely scaly, 

 reaching a little past middle of eye, fourth to sixth funicular segments 

 submoniliform. seventh distinctly broader than long. Prothorax 

 nearly as wide at apex as at base, widest in front of middle, sides 

 converging and just perceptibly sinuate toward base, not constricted 

 apically, ocular lobe distinct ; pronotum evenly convex, the setae 

 subprostrate and inconspicuous. Elytra broadly emarginate at base, 

 sides nearly straight and slightly convergent behind the unusually 

 narrow shoulders, surface even, the sutural interval not elevated on 

 declivity ; scales in serial punctures rounded, about same size and 

 sometimes same color as the surface scales, the former then scarcely
