AMERICAN COLEOPTERA. 179 



not fossorial, the outer edge spinous, middle tibise on the outer edge biseriately 

 spinulose, the posterior more finely so. Posterior tarsi slender with joints 1 — 4 

 gradually decreasing in length. 



This genus is known from any in the tribe by its prominent 

 and smooth mandibles, the non-fossorial tibiae, the absence of scutel- 

 lar stria, while the form of the ligula and paraglossse distinguishes 

 it from Daptus. 



P. piceus n. sp. — Moderately elongate, parallel, piceous, shining, legs pale 

 testaceous. Head smooth, a moderately deep arcuate impression each side. An- 

 tennfe piceous, two basal joints pale. Tliorax transversely cordate, sides arcuate 

 and narrowing posteriorly, hind angles small moderately prominent, base arcuate, 

 ^pex very feebly emarginate, disc moderately convex, median line finely impressed, 

 a short intra-angular basal impression, surface jmooth, shining. Elytra oblong, 

 parallel, humeri obtuse, surface striate, the striae, entire and not punctate, no 

 scutellar stria, intervals flat, smooth. Body beneath piceous, shining, tip of 

 abdomen paler, surface smooth, impunctate. Length .24 inch ; 6 mm. 



I have but one specimen, a female, from Texas, given me by Mr. A. 

 S. Fuller. 



Group Glypti. 



I have already given the reasons not only for placing Glyptus in 

 the present tribe but also for considering it a group apart. With the 

 exception of the characters which mark it as a special type in the tribe 

 it seems to bear the same relation to the Harpali which follow, that 

 Geopinus does to other Dapti. G. scu/pfi/is Br., is figured by Lacor- 

 daire (Genera, Atlas, pi. 10, fig. 3), in such a position on the plate as 

 to make its comparison with the better figure of Geopinus quite easy. 

 The species above cited occurs in western part of Africa and lives 

 in the nests of White x\nts. A second species has been described by 

 Chaudoir from Egyj)t. 



Group Harpali. 



It is extremely difficult to draw the line with accuracy between this 

 group and the Dapti, and I am convinced that other characters will be 

 found which will separate the genera but which will not allow the groups 

 to remain as at present con.stituted. 



Not having access to as much exotic material as I desire I cannot 

 venture on a discussion of the genera which should be here included, 

 and will confine my remarks to those of our own fauna. 



At the time of the publication of the " Classification of the Coleoptera 

 of North America," by Dr. LeConte, six genera were placed in the 

 Harpali. Since then two have been suppressed Philodes (= Stenolophus) 

 and Gynandrotarsus (r= Anl&odactyhis). It is however necessary to 

 add Stenomorphus, and Selenopliorua should be rehabilitated as sug- 

 -:>s^-d1.v Dr. L:CaKj.
