middle and rounded. Eyes touching the base of the man- 

 dibles, strongly divergent towards the clypeus, separated on 

 the vertex by a distance equal to about twice the combined 

 length of the two basal joints of the flagellum ; posterior 

 ocelli much nearer to each other than to the eyes. Clypeus 

 shining, sparsely punctured; front finely and very closely 

 punctured; vertex and thorax more strongly punctured. 

 Basal area of the median segment smooth and shining, 

 divided by a broad longitudinal groove ; the apical slope 

 steep, finely and very closely punctured. Abdomen minutely 

 and closely punctured, the ventral surface much more coarsely 

 and very sparsely punctured. Fore metatarsus with six 

 spines.

Not very near any other species; the head is much larger 

 than in P. basalts, Sm., and the median segment is shorter 

 and very different in sculpture. In P. dentatun, Cam., the 

 head is as large, but the clypeus and median segment are 

 very different.

? . Clypeus clothed with delicate silver pubescence; third 

 joint of! the flagellum twice as long as the first, the second 

 distinctly shorter; eyes separated on the vertex by a distance 

 about equal to the length of the third joint o£ the flagellum. 

 Pronotum obliquely depressed, with a shallow longitudinal 

 median line, the middle of the hind margin level with the 

 mesonotum. Thorax opaque, scutellum and postscutellum 

 shining. Median segment longer than broad, narrowed 

 towards the apex ; the dorsal surface coarsely, rugosely, 

 transversely striated, with a distinct longitudinal carina ; the 

 sides of the segment closely obliquely striated ; the face of 

 the posterior truncation indistinctly transversely striated, 

 with a deep median sulcus. Tergites 1-3 with a broad but 

 ill-defined apical band of dull whitish pubescence ; sixth 

 tergite bare, delicately punctured, narrow, the sides con- 

 verging towards the apex, which is very narrowly truncate ; 

 second sternite not swollen at the base. Radial cell obliquely 

 truncate at the apex; first abscissa of the radius as long as 

 the second and third combined, Tarsal ungues long, with a
