COLEOPTERA. 87 



they are nearly twice as wide as tlie latter ; sides evenly and strongly arcuate 

 throughout ; together rath.er ohtusely rounded at the apex ; disk convex, 

 sliglitly less than twice as long as wide, coarsely rather strongly and some- 

 what densely and evenly punctate ; punctures im])ressed, interspaces slightly 

 convex. Legs long and very slender ; femora slender, rather abruptly 

 clavate near the tips ; tarsi very slender, first joint of the posterior nearly 

 twice as long as the second and longer than the fifth, joints two to four uni- 

 formly and very gradually decreasing in length. Length 1.4 mm. 



Ann Arbor, Michigan (Schwarz), 1. 



Distinguishable from Afotschulskii by its smaller size, absence of 

 pronotal foveae, and very coarse punctuation of the elytra. 



Employing the characters given by Dr. LeConte (N. Sp. Col. p. 20) 

 for the two species described by him, we have the following table : — 



Prothorax short, nearly as wide as long. 



Pronotura punctured behind gl'OSSUS. 



Pronotum not punctured behind ; much smallerspecies...]fIotsclnilsk.ii. 

 Prothorax much longer than wide. 



Elytra very feebly and sparsely punctulate Testalis. 



Elytra coarsely densely and strongly punctate, pillictatlis. 



BRYAXIS Leach. 



B. facilis n. sp. — Form rather slender. Color piceous, antennae very 

 slightly paler, elytra rufous, darker in a narrow transverse apical band, legs 

 pale reddish^llavate ; pubescence excessively short and sparse, recumbent. 

 Head much longer than wide ; interocular surface impunctate, having three 

 deeply impressed circular spongy-pubescent foveae, which are exactly equal 

 and at the vertices of an equilateral triangle ; intermediate surfaces rather 

 strongly convex ; eyes rather large and prominent, very coarsely granulated ; 

 antennae distinctly longer than the head and prothorax together, slender, 

 first three joints decreasing uniformly in length and thickness, very slowly 

 in the former and rather rapidly in the latter sense, third joint two-thirds 

 longer than wide, joints three to seven equal, slender, and cylindrical, eighth 

 scarcely as wide, quadrate, ninth slightly elongate, cylindrical, slightly 

 thicker, tenth scarcely longer than wide, slightly trapezoidal, a little thicker 

 than the ninth, eleventh slender, thicker than the tenth, as long as the three 

 preceding joints together, obliquely and finely acuminate. Prothorax slightly 

 wider than the head, widest very slightly before the middle, where it is 

 about one-four,th wider than long ; sides strongly arcuate, almost straight 

 toward the apex and base, the former three-fifths as long as the greatest 

 width, and very slightly shorter than the latter, both equally and very 

 feebly arcuate ; disk very strongly convex, impunctate ; lateral foveae large, 

 spongy-pubescent, at one-third the length from the base; median very small, 

 in the form of a nude puncture, very near the base, not connected with the 

 lateral foveae. Elytra at base slightly wider than the pronotum ; sides 

 strongly divergent posteriorly and feebly arcuate, transversely truncate be- 

 hind ; disk rather convex, slightly shorter than wide, rather finely, closely.
