AMERICAN COLEOPTERA. 91 



opaque, finely alutaceous, sparsely punctate. Legs and antennae pale. Length 

 .14— .20 inch ; 3.5—5 mm. (PI. I, fig. 6). 



The tooth of the claws is rectangular at its free end and is not 

 half the length of the claw. The rows of eljtral punctures are often 

 very indistinct. 



Occurs from the Middle States westward to Missouri and south 

 to Florida. 



P. angnstata n. sp. — Similar in form to the preceding but more slender 

 and parallel. Length .14 — .18 inch; 3.5 — 4.5 mm. 



The principal differences between this and the preceding species 

 are those given in the table. The tooth of the claws is more pro- 

 longed and extends beyond the middle in the posterior claws, and 

 in the anterior claws is still longer, so that a form similar to that of 

 Phy talus is produced. 



Three specimens, Florida. 



Tribe II. — Eucinetini. 



Head strongly deflexed, resting on the anterior coxae, front pro- 

 longed in a feeble beak, frontal suture distinct. Labrum moderately 

 prominent concealing the mandibles. Antennae filiform. Labial palpi 

 with terminal joint ovoid, of the maxillary cylindrical pointed at tip. 

 Thorax short, narrowed in front, beneath with an extremely short 

 prosternum in front of the coxae and a small prolongation at middle, 

 side pieces entirely wanting. Anterior coxae long and without tro- 

 chantin, received in repose in cavities on each side of the mesosternum. 

 The latter separating the middle coxse, anteriorly a triangular de- 

 pression which receives the small point of the prosternum in repose, 

 middle coxae oval, not prominent and without trochantin, the side 

 pieces large, diagonally divided and nearly equal. Metasternum very 

 short, acutely prolonged at middle between the posterior coxae, the 

 episterna of moderate width, narrowed behind and without epimera. 

 Posterior coxae formed of broad plates which attain the side margin 

 of the body and cover the greater part of the first ventral segment. 

 Legs moderately long, slender, anterior tibiae without spurs, middle 

 and posterior with rather long spurs. Tarsi slender, gradually attenu- 

 ate to tip, joints 1 — -i gradually decreasing in length, last joint a little 

 longer than the fourth. Claws small, simple. Body oval-elliptic or 

 navicular, convex, pubescent. (PI. I, fig. 7, details). 



The males have the anterior tarsi dilated and a distinct sixth 

 ventral segment. The anterior tarsi of the female are slender, and 

 the sixth segment in some species not visible and in others very
