segments very strongly impressed at base tlirough about one-half of their 

 length ; fourth and fifth equal in length. Legs rather short ; posterior tarsi 

 very much shorter than the tibiae, with the first joint distinctly shorter than 

 the next three. Length 4.0^.2 mm. ; width 1.2 mm. 



New York (Catskill Mts.); North Carolina. 



The middle coxte are moderately distant, the mesosternal process 

 extending nearly to the apex, with its sides becoming parallel, the 

 apex transversely truncate with the angles right and not rounded, 

 the apical margin just visibly bisinuato, the fine acute median carina 

 extending to the tip, the space between the carina and side margins 

 broadly concave. This species is about twice as large as the Euro- 

 pean morion Grav., and has much longer antennae. 



B. thoracica n. sp. — Stout, thick, parallel, polished, black, the lateral 

 limbs of the pronotum feebly rufescent from diaphaneity ; elytra, tip of the 

 abdomen, legs and basal joint of the antennae clear pale rufous ; head ex- 

 tremely minutely, scarcely visibly, remotely punctate ; pronotum very finely, 

 sparsely, uniformly so ; elytra strongly, rather closely and asperately ; abdo- 

 men sparsely, unevenly, subrugosely sculptured ; pubescence rather short, 

 not very dense, stiff, inconspicuous, long and sparse on the abdomen. Head 

 strongly deflexed, oval, longer than wide, less than one-half as wide as the 

 prothorax, convex ; eyes well developed ; antennje long, distinctly incrassate, 

 extending fully to the middle of the elytra, third joint feebly obconical, nearly 

 three times as long as wide, longer than the second, tenth very slightly wider 

 than long. Prothorax large, transversely suboval, three-fifths wider than long ; 

 sides broadly, strongly arcuate, convergent anteriorly becoming gradually 

 parallel in basal half; base broadly, rather strongly arcuate, miicli wider 

 than the more feebly arcuate apex ; basal angles very obtuse and rounded but 

 not obliterated; disk evenly, strongly convex, without trace of impression. 

 Elytra very short, twice as wide as long, not in the least wider than the disk 

 of the pronotum and scarcely more than two-thirds as long as the latter ; sides 

 just visibly divergent and arcuate from the base ; disk not impressed, the 

 apex transverse. Abdomen — when contracted — not longer than the anterior 

 parts, at base as wide as the elytra; sides subparallel, becoming feebly con- 

 vergent toward apex ; first three segments narrowly, deeply impressed along 

 the base ; fifth distinctly longer than the fourth. Legs rather long ; posterior 

 tarsi very long and slender, only slightly shorter than the tibise, with the 

 basal joint fully as long as the next three combined. Length (contracted) 

 3.0 mm. ; width 1.1 mm. 



Canada (Grimsby). 



The abdomen is reflexed from the base. The middle coxas are 

 moderatel}'" distant, the mesosternal process extending nearly to 

 their apices where it is as usual superposed on the tip of the short 

 metasternal projection ; the sides of the process are feebly conver-
