striation ; elytra constricted just above the apical impression, 

 which is vertical with an emargination of equal width above 

 and below, lineate-punetate, with flat interstices very irre- 

 gularly and remotely punctured. 



Female. — Paler than the male, the elytra rather darker 

 posteriorly close to the declivity; prothorax with a broad 

 patch of punctures extending the whole length of the median 

 sulcus, which is similar in length but much less impressed 

 'than that of the male; the rest of the surface is similar to 

 the male. Elytra very feebly lineate-punctate, except the 

 sutural rows, the interstices with only a few very minute 

 punctures; the apical depression lunate with a subconeave 

 fundus, which is rugulose and hairy. 



This species belongs to Chapuis's group Oupulati, and 

 is very closely allied to P. biuncus, Blandf., from which it is 

 separated b) being slightly shorter and much broader, with 

 the apical processes in the male not approximating at the tip, 

 the postero-lateral angles being right angles : on the other 

 hand, the frontal sculpture is xevy similar in both, and 

 possibly the present species may merely be a local variety. 

 As want of material prevented dissection, M. Chapuis's 

 diagnosis of sex has been followed. 



Diapus, Chap. 



In the three following new species, whilst they agree 

 with the generic characteristics in other respects, the labial 

 palpi are undoubtedly three-jointed. As M. Chapuis both 

 figures and describes the palpi as two-jointed, it becomes 

 necessary to enlarge the diagnosis so as to include two or 

 three joints, as, similarly, Chapuis describes those of Crosso- 

 tarsus as one- or two-jointed.
