Tho nietash^riium laterally between the co^Ja' is short, in lenoth 

 about equal to the width of a niesotil)ia at middle. 



The tibial o-rooves of the femora are entire, gflabrous, flat to more 

 or less concave, their margins moderate to feeble and acute, converg-- 

 ing to the femoral base in each, where they are scarcely contiguous. 



The external surfaces of the tibia? are as in planum. 



The tarsi moderate as usual. 



The protarsi are about one-fourth of their length shorter than a 

 mesotarsus. First four joints small and subequal, the first distinctly 

 longer than Avide, second, third, and fourth as wide as long: the fifth 

 about equal in length to the preceding three combined. 



The mesotarsi are about one-fifth of their length shorter than a 

 metatarsus. The first joint is about one and a half times longer than 

 the second ; joints two to four inclusive are sul)equal in length and a 

 little longer than wide; the fifth about ecjual in length to the pre- 

 ceding three taken together. 



The metatarsi are about two-thirds as long as their respective meta- 

 tibia. The first joint is about equal to the second and third combined ; 

 the fourth equal to the first : the second and third are subequal in 

 length and about one and a half times longer than wide. 



EMBAPHION CONTRACTUM, new species. 



Oblong-oval, piceous black, feel)ly shining to subopaque, sides of 

 the body not foliaceous, acute elytral margin not attaining the apex; 

 pronotum constricted in basal eighth ; each puncture with a very 

 short, semierect seta. 



Head moderately large, more or less plane to feebly convex between 

 the eyes, rather broadly and distinctly impressed within the supra - 

 antennal convexities, frontal suture more or less feebly evident ; 

 surface s])arsely, irregularly, and somewhat finely punctate, punctures 

 slightly denser at the peripher3\ 



Antefimi^ long and moderately slender, outei- four joints feebly 

 compressed and scarcely dilated; third joint equal to the next two 

 taken together; fourth scarcely longer than the fifth; the latter to 

 the seventh, inclusive, subequal in length; eighth subtriangular and 

 longer than wide; ninth and tenth very feebly transversely oval; 

 eleventh pointed ovate and scarcely longer than wide. 



Pronotum with the total width about one-half greater than the 

 length, margin acute and not foliaceous; disc proj)er about as wide 

 as long, moderately, broadly, and evenly convex, sparsely, irregularly, 

 and not strongly punctate, with a more or less feeble transverse anti 

 basal impression, laterally rather broadly imjDressed or feebly con- 

 cave within the slightly reflexed acute margins, surface here more 

 opafjue and obsoletely sculptured; apcr broadly, evenly, and moder-
