Fig. 12a, represents the prothorax of this species, shewing the very broad hind part; fig. 124, the antenna 
seen directly from above, shewing the acute basal angle with a deep impression near the base, the four mar- 
ginal conical projections, each emitting, as well as the pointed apex of the club, a strong bristle; between the 
basal angle and the first: setigerous lobe is seen the first or basal projection of the opposite margin of the elub ; 
fig. 12a shews the antenna seen from behind, shewing the broad oval excavation of the club.

Most nearly allied to the Chinese Paussus Bowringii Westw., Proc. Linn. Soc. June 19, 1849; but at once 
distinguished by the spineless lateral margin of the fore part of the prothorax, the broad posterior tibie, &c.

Nearly allied to P. Boysii, thoracieus, &e. The head terminates in front in two slightly rounded and flat- 
tened divisions, the incision between which is angular, and terminates in a shallow channel extending to the 
crown of the head, where it terminates in two deep oval rather oblique impressions, each having a small raised 
tubercle within. The club of the antennz is triangular, with the front margin acute and slightly arcuated; the 
hinder or upper margin is very deeply excavated, the excavation of an oval form, with each side suleated. The
