Hitherto known from New Guinea only, the type (Q) being 

 in the Oxford Museum. This species which is of a very pale 

 testaceous colour, is readily recognized by two parallel bands 

 across the head ("caput fuscente bifasciatum"), viz., a pale 

 brown band between the upper margins of the eyes, and a 

 more distinct black one between the lower margins. Rhelford 

 (Gen. Ins. fasc. 73, p. 14) regarded this species as synonymous 

 with P. propinqua Walker, from Celebes. How^ever, as the 

 latter, the type (9 )* of \\hich is also in Oxford, does not show 

 the bands across the bead, it will be safer to keep the two 

 species separate.
