PiNOPHiLus, Grav. 



Palpi filiform ; but the antennae inserted before the eyes, outside of 

 the labrum, and near the exterior base of the mandibles *. 



Lathrobium, Grav. — P^ederus, Fab. 



Palpi suddenly terminated by a pointed and frequently indistinct 

 joint, much smaller than the penultimate ; those of the maxillae much 

 longer than the labials ; the antennae inserted as in Pinophilus ; 

 anterior tarsi strongly dilated in both sexes ; length of the last joint 

 of the four posterior tarsi almost equal to that of the four preceding 

 ones taken together f . 



In the second section, that of the Longipalpi, where the head is 

 also completely exposed, but the labrum entire, the maxillary palpi 

 are nearly as long as the head, and have a clavate termination formed 

 by the third joint, with the fourth concealed or but slightly visible, 

 and in the figure of a small point, terminating the club when appa- 

 rent ; the preceding joint considerably enlarged. These Insects live 

 along the shores of rivers, &c, 



P^DERUS, Fab. 



The antennae inserted before the eyes, either filiform or gradually 

 increasing in thickness, and longer than the head ; body long and 

 narrow; mandibles dentated on the internal side, and terminating in 

 a simple joint. 



In some of them, Pjldeuus, Lat. — the penultimate joint of the 

 tarsi is bifid \. 



P. riparius ; Slaphylinus riparius, Panz., Faun. Insect, Germ. 

 IX, 2. About three lines in length ; very narrow and elongated ; 

 fulvous; head, pectus, superior extremity of the abdomen and 

 knees, black ; elytra blue. Very common in wet sand, under 

 stones, among the roots of trees, &c. 



In the others, Stilici, Lat. — all the joints of the tarsi are entire §. 



* Pinophilus latipes, Grav., North America. In his Mantissa it is united to the 

 following genus.

 The L. elonrjatum {S. chmjatus, L.) is figured by Panz., lb. IX, 12; — StaphyUnus 

 linearis, Oliv., Col. Ill, 2, iv. 38. See also Gyllcnh., Insect. Suec. I, pars I, p. 363, 

 et seq., and the Catalogue of Count Dejean, p. 24. 



;}: M. Lefevre has brought an Insect from Sicily allied to Pa;derus, but evidently 

 forming a new genus. The fourth and last joint of the maxillary palpi is here very 

 distinct, and gives them a clavate termination. The last joint of the antennae is 

 ovoido-conical and larger than the penultimate. The head is connected with the 

 thorax by an elongated pedicle, on a level with the former at its origin. The thorax, 

 is narrow and elongated. The two anterior tarsi are greatly dilated ; the first joint 

 of the others is very long, and their penultimate appeared to me emarginated or bifid. 

 I will distinguish the genus by the name of Procirhus, and this species shall be 

 dedicated to the zealous naturalist who discovered it.
