side-pieces of the under surface not at all dif ferentiated ; proster- 

 num moderately long before the coxae, which are small in size 

 but rather prominent, contiguous and with their cavities narrowly 

 closed behind. Elytra cylindric, irregulär punctate, entire, the 

 epipleurae vertical, defined by a fine line near the margin, wider 

 and oblique in plane at base. Mesosternum narrowly separating 

 the middle coxae and intervening at the sides between the cavities 

 and the side-pieces, the episternum in isosceles triangle with the 

 apex behind, the epimeron a long scalene triangle separating the 

 episternum from the sides of the closed elytra throughout. Meta- 

 sternum moderately long, the episternum narrow, disappearing 

 under the elytra behind ; bind coxae apparently slightly separated, 

 transverse, extending to the sides of the body. Abdomen con- 

 sisting of five free segments, with transverse apices and without 

 exposed connective membrane, the first as long as the next two, 

 the last four gradually diminishing in length. Legs short and very 

 stout; femora much swollen throughout but especially the an- 

 terior; tibiae short and stout, obliquely truncate at tip, apparently 

 without terminal spurs; tarsi short and stout, 5 — 5 — 4-jointed, 

 the last Joint as long as the remainder in all, the anterior pair very 

 broadly dilated and densely clothed with stif f yellowish hairs beneath ; 

 claws rather stout, well developed, arcuate, simple and divaricate."

A. crinita n. sp. Parallel, subcylindric, feebly depressed 

 above, shining, dark rufo-testaceous and somewhat sparsely clothed 

 throughout with moderately long, stiff , erect hairs ; legs and elytra 

 brighter rufous. Head subdeflexed, fully as long as wide, cylindri- 

 cally and evenly convex above, strongly punctate, the punctures 

 slightly elongate, well separated but closer and subrugose near 

 the sides of the front; eyes as nearly twice their length from the 

 prothorax; antennae as long as the prothorax, sparsely bristling, 

 the first joint globularly enlarged to some extent. Prothorax as 

 long as wide, very feebly narrowed and with slightly arcuate sides 

 from apex to base; apex transverse, feebly arcuate toward the 

 angles, which are not prominent; basal angles obtuse; surface 

 subcylindrically convex, even, the basal margin depressed beneath 

 the surface; punctures deep, strong, moderately coarse, distinctly 

 separated, becoming slightly elongate toward the sides, the mar- 

 ginal serrulation exceedingly fine, feeble and obtuse. ScuteUum 

 flat, moderately small, transversely oval. Elytra parallel, with 

 the sides straight, semicircularly rounded at tip, longer than 

 wide, 2^/3 times as long as the prothorax and fuÜy ^/^ wider; 

 base truncate, the humeri feebly tumid, slightly more than right, 

 but forming a distinct angle; surface feebly flattened toward the 

 suture, coarsely, deeply and irregularly punctate, the punctures 

 becoming gradually smaller behind, well separated throughout. —
