334 MEMOIRS ON THE COLEOPTERA 



abundant bristling pubescence gives to the type a distinctive 

 appearance, not suggested in any species of Euphoria; it may be 

 described as follows: 



Body oblong-oval, rather convex, moderately shining, blackish-piceous, 

 the elytra throughout pale luteous; pubescence pale yellowish- 

 brown, very long, dense, bristling and conspicuous throughout 

 above, beneath and on the legs, conspicuous but not so dense on the 

 elytra; head finely, moderately densely punctate, the clypeus 

 broad, shorter than wide, parallel, the apex distinctly reflexed and 

 arcuate, with a mere vestige of a feeble medial sinuation; hairs 

 radiating from a central point, very dense and long on the front and 

 vertex; antennal club castaneous, not quite as long as the entire 

 stem; prothorax short, nearly two-fifths wider than long, the sides 

 more arcuate medially, parallel thence to the base, the basal sinus 

 broad and shallow, the limiting angles obtuse and rounded; punctures 

 fine, shallow, linear, dense and forming oblique lines laterally, more 

 separated, deeper and punctiform medially, wanting along a well 

 defined tumid median line, along the base and in an irregular oblique 

 discal area at each side; scutellum acute, smooth, with a few fine 

 setigerous punctures along the sides, except posteriorly, the surface 

 apically with a feeble canaliculiform impression; elytra longer than 

 wide, a fourth wider than the prothorax, subparallel, the humeri 

 moderately prominent laterally, the sinus longer than usual and not 

 so abruptly formed; suture obtusely elevated, more carinate pos- 

 teriorly, the sutural angles dentiform and slightly produced; costse 

 feeble, stronger toward the subapical umbo, the intervals with close 

 . arcuate interlacing incised lines, becoming smaller, sparser, deeper 

 and more punctiform on the flanks; pygidium with two widely 

 separated umbones, the surface finely, densely, confusedly strigilate 

 and with dense, very long and conspicuous pubescence; sterna later- 

 ally with fine irregular confused strigilation; abdomen finely, not 

 very sparsely punctured medially, with a narrow deep groove along 

 the middle basally in the male; anterior tibiae shorter than the tarsi, 

 about twice as long as wide, tridentate, the upper tooth feeble and 

 obtuse, closer to the second than the latter is to the apical. Length 

 (cf) 1 1. 8-12. 8 mm.; width 6.3-7.3 mm - Nebraska. [Euphoria

The female appears to be much less abundant than the male, 

 of which I have at hand four specimens, received through the kind- 

 ness of Mr. Knaus. The aberrant nature of this species seems to 

 have wholly escaped the notice of the original describer, who does 

 not even make any allusion to the side margins of the pronotum, 

 very much abbreviated and compressed hind tarsi or the binodose 

 pygidium of the male.
