346 MEMOIRS ON THE COLEOPTERA 



scutellum in great part squamose; elytra slightly inflated behind 

 the middle and a third wider than the prothorax, rather smooth, 

 the punctures somewhat close-set and bearing small slender 

 yellowish squamules, which extend to the dense white vittae and 

 not separated therefrom by glabrous lines as in the preceding 

 forms; pygidium small, equilateral, having small close-set whitish 

 squamules, largely replaced by very fine hairs along the median 

 line, these fine brown hairs also very distinct throughout and not 

 visible in lo-lineata; legs rather short; middle tarsi much shorter 

 than the tibiae. Female not known. Length 22.0-22.5 mm.; 

 width 10.4-10.7 mm. Washington State. Two examples. 



reducta n. subsp. 



Body large in size and with a much broader bisinuate clypeus. Form 

 oblong-oval, piceous-black, the prothorax bright rufous; abdomen 

 black; vestiture abundant, very pale yellowish, the dense vittae 

 white; head large, short; vertex with many erect hairs and scattered 

 scales, which are dense and whiter laterally; clypeus nearly two and 

 one-half times as wide as long, parallel and nearly straight at the 

 sides, the angles right and blunt, the apex feebly bisinuate, the surface 

 concave, with close-set broad pointed scales, becoming much smaller 

 and denser apically; antennal club pale, three times as long as the 

 stem; prothorax very short, two and one-half times as wide as long, 

 very broadly and rather feebly lobed at base, angularly prominent 

 at the sides, the punctures only moderately coarse, rather close-set 

 and very shallow, each with a broad pointed scale, gradually smaller 

 but otherwise similar laterally and between two and three times as 

 long as wide, the three white vittae distinct, the sublateral broadly 

 interrupted before the middle; scutellum densely squamose, broadly 

 glabrous laterally and apically; elyt'ra feebly rugulose, closely punc- 

 tate and with close-set slender pale yellowish lanceolate scales, 

 three to four times as long as wide, the part adjacent to the rather 

 broad white vittae smoother and glabrous; pygidium but little wider 

 than long, very moderate in size, extremely densely clothed through- 

 out with very small and finely pointed whitish scales; legs rather 

 slender, the femora pale rufous, the remainder rather darker. Length 

 28.0 mm.; width 13.0 mm. One example. 



Female nearly like the male but a little larger and broader, the 

 elytra similarly arcuately narrowing behind from near the middle; 

 clypeus shorter, three times as wide as long, the apex more strongly 

 bisinuate, the sides parallel and arcuate and the angles more distinct, 

 the surface flat, abruptly reflexed at apex, similarly squamose; 

 antennal club small, barely more than half as long as the stem; 

 prothorax as in the male but less abbreviated, but little more than 

 twice as wide as long, the punctures similarly rather close-set and 

 notably shallow, the depressed scales and vittae similar; scutellum 

 less broadly squamose medially; elytra a little shorter and broader, 

 similarly with broad dense white vittae and close-set yellowish inter- 

 stitial squamules; legs stouter as usual. Length 29.0-30.0 mm.; 

 width 14.0-14.4 mm. Two examples.
