ROLAND HAYWARD. 131 



Feebly convex: rufous or rufo-piceous ; tliorax slightly wider than long, dis- 

 tinctly narrower at base than apex, hind angles rectangular; striae of the 

 elytra sparsely and very finely punctate. Length .17 -.22 inch. 



oblonguliiiii Mann. 

 Larger; moderately convex ; dark piceous or nearly black; thorax distinctly 

 wider than long, scarcely narrower at base than apex, hind angles sub- 

 acute ; strife of the elytra obsoletely punctate. Length .23-.24 inch. 



spectabile Maun. 



123. B. obloiiguliini Mann. — Form elongate, feebly convex : color rufous 

 or rufo-piceous, shining. Head slightly narrower than the thorax at apex ; palpi 

 rufous; antennae about one-half the length of the body, rufous. Prothorax 

 trapezoidal, slightly wider than long, distinctly narrower at base than apex, 

 sparsely punctate at base ; apex slightly eniarginate ; median line deep, entire : 

 anterior transverse impression rather feeble, the posterior distinct; basal impres- 

 sions broad, moderately deep, bistriate; sides with the margin narrowly reflexed, 

 slightly arcuate in front, sinuate behind ; hind angles rectangular, very finely 

 carinate. Elytra slightly wider than the thorax, oblong-ovate, moderately deeply 

 striate, more finely towards the sides: striae entire, sparsely, very finely punctate, 

 the fifth slightly grooved at tip ; intervals slightly convex, the third with the first 

 dorsal puncture about one-third from base, the second about one-third from apex. 

 Body beneath and legs rufous. Length .17-. 22 inch ; 4.25-5.5 mm. 



Distinct from spectabile by its proportionally longer thorax, which 

 is more narrowed behind, with the hind angles rectangular, as well 

 as by its more elongate, less convex form, different color and smaller 

 size. 



Its range of distribution is extended. I have seen specimens from 

 Canada, Portland, Me. (Blanchard), Vermont, the White Mountains 

 of New Hampshire, Massachusetts (Lowell), Ohio, Michigan, Alaska, 

 California and Mexico. 



124. B. spectabile Mann. — Form elongate, moderately convex ; color dark 

 piceous, nearly black, shining. Head scarcely narrower than the thorax at apex : 

 palpi rufo-piceous; antennae rather more than one-half the length of the body, 

 rufo-piceous. Prothorax trapezoidal, distinctly wider than long, scarcely nar- 

 rower at base than apex, sparsely punctate at base; apex slightly eniarginate; 

 median line deep, abbreviated in front; transverse impressions moderately dis- 

 tinct; basal impressions broad, moderately deep, bistriate : sides with the margin 

 narrowly, but distinctly reflexed. arcuate in front, sinuate behind ; hind angles 

 subacute, finely carinate. Elytra oblong-oval, distin(;tly wider than the thorax, 

 moderately deeply striate ; striae entire, obsoletely punctate, the fifth slightly 

 grooved at tip ; intervals convex, the third with the first dorsal puncture slightly 

 in front of the middle, the second about one-third from apex. Beneath piceous. 

 the abdomen sometimes tinged with rufous. Legs rufo-piceous. Length .23-. 24 

 inch ; 5.75-6 mm. 



A very rare species of which I have seen but two examples, one 

 each in the LeConte collection and in that of Dr. Horn. It is dis- 

 tinguishable from the preceding by the characters given above. 



It is known to me only from Alaska and Vancouv^er Island.
