c? . The clypeus is distinctly pointed at the apex ; the eyes a 

 little further apart on the vertex than in the female, and the 

 sculpture of the median segment a little coarser.

This is veiy near spinolce, but is distinguished by the pimc- 

 tured thorax and the greater distance between the eyes on the 

 vertex.

 This species has the thorax and median segment much more 

 coarsely punctured than in congener, the second abscissa of the 

 radius is also much longer, and the eyes are further apart on the 

 clypeus. It is very near P. nitidus Sm., from Aru, but has the 

 eyes further apart on the vertex than in that species, and the 

 sculpture of the median segment coarser, with a much less 

 distinct sulcus.

Easily distinguished by the coarse puncturation of the head, 

 thorax, and median segment, and by the strongly constricted " 

 abdominal segments. The punctures of the dorsal segments are 

 very distinct ; the second ventral segment is rather sparsely 

 punctured, especially in the middle. The antennae are short and 

 rather stout. The nearest relation is P. constriction Turn., from 

 New Guinea, but the sculpture is much less coarse in that 

 species, and the puncturation of the second ventral segment is 

 djfferent.

The abdomen in this species is almost entirely covered with 

 golden pubescence, which forms denser bands on the apical 

 margins of the segments. There is a spot of silver pubescence 

 at the apical angles of the first dorsal segment.
