ROLAND HAYWAKD. 83 



B. militare Casey is undoubtedly synonymous with this species. 



It is known to me from JNIaine, Massachusetts, New York, Penn- 

 sylvania, the Lake Superior region, Minnesota, Missouri, Kansas 

 and Texas. 



55. B. texaiiuui Chaud. — Form rather slender, elongate, moderately con- 

 vex ; color varying from brownish to black, slightly seneous, shining. Head as 

 wide as the thorax at apex ; palpi rufous; antennae about one-half the length of 

 the body, fuscous, the basal joints rufous. Prothorax about one-half wider than 

 long, slightly narrower at base than apex; apex nearly truncate ; median line 

 fine, extending between the transverse impressions, which are feebly marked, 

 the anterior nearly obsolete ; basal impressions small, deep, rather feebly bistriate ; 

 sides with the margin narrowly reflexed, moderately arcuate in front, slightly 

 sinuate in front of the hind angles, which are obtuse, but not rounded, carinate. 

 Elytra scarcely one-half wider than the thorax, elongate, oblong-ovate, moder- 

 ately deeply striate, much more finely towards the tip; strife distinctly punctate 

 to behind the middle, the two inner only entire, the fifth represented by a groove 

 at apex ; third stria with the first dorsal puncture about one-third from base, the 

 second about one-third from apex : intervals slightly convex. Beneath varying 

 from brownish to black, shining. Legs rufous. Length .23-. 28 inch ; 5.75-7 mm. 



Closely allied to the preceding, but larger and more elongate. The 

 thorax is less narrowed behind, with the sides less strongly arcuate 

 in front, and but slightly sinuate in front of the hind angles, wiiich 

 are obtuse, but not rounded. The elytra are less oval and more 

 elongate. 



It is known to me from Texas, the Indian Territory, Missouri and 

 Iowa City, Iowa (Wickham). 



56. B. siibaiigUKtalliin n. sp. — Form slender, elongate, convex; color 

 piceous or nearly black, sometimes very slightly jeneous, shining. Head as wide 

 as the thorax at apex; palpi dark rufous; antennpe about one-half the length of 

 the body, fuscous, the basal joints paler. Prothorax slightly wider than long, 

 slightly narrower at base than apex; apex nearly truncate; median line fine, 

 usually abbreviated at each end ; transverse impressions distinct ; basal impres- 

 sions small, deep, bistriate; sides with the margin narrowly retiexed, arcuate in 

 front, sinuate behind ; hind angles moderately prominent, acute, carinate. Elj^tra 

 less than one-half wider than the thorax, oblong-ovate, deeply striate ; strise less 

 deep at the sides and towards the tip, distinctly punctate to behind the middle, 

 the two inner only entire, the fifth represented by a groove at tip; thiid strin 

 with the first dorsal puncture slightly in front of the middle, the second alxmt 

 one-fourth from apes ; intervals slightly convex. Beneath nearly black (rufo- 

 piceous in some specimens, probably from immaturity), shining. Legs rufous. 

 Length .22-. 25 inch ; 5.5-6.25 mm. 



This species is most nearly related to fexanum, from whicli it dif- 

 fers by its smaller size, more slender form and proportionally longei' 

 thorax, the sides of which are more distinctly sinuate behind and 

 the liind angles acute and slightly prominent.
