at the apex of the mesonotum, the centre of the scutellum aud of

 yellow ; wings ferruginous, broadly iufuscated at apex, the nervures 

 and tegulae ferruginous ; abdomen black, with a broad abbreviated

2 . Closely resembles P. pedestris. Smith, differs in structure in 

 the following points : — the clypeus is broader, its anterior margin 

 heing transverse ; in pedestris the anterior margin is oblique at the 

 sides and widely emarginate in the middle ; the pronotum is longer 

 with a more gradual slope anteriorly, the median segment is 

 slightly longer, and the abdomen more sessile aud thicker at base. 

 In colour P. rothneyi has the flagellum of the antennae below and 

 the posterior femora and tibiae black instead of red, and there is 

 no yellow fascia on the posterior margin of the pronotum. The 

 two species e.xist together, but, so far as I have been able to 

 observe, P. rothnmji frequents the thickest forest, while pedestris is 

 to be found in the open and occasionally comes into houses.

5 . Head, thorax, and abdomen densely pruinose ; the clypeus 

 transverse, its anterior margin widely emarginate ; the front 

 of the face flat ; the median segment compressed at the sides, 

 subconvex, nearly level above, posteriorly emarginate ; legs with 

 the tarsi spinose, the spines stout and scattered; claws bitid ; 

 abdomen pseudosessile. Black, covered with a dense silvery-grey 

 pile, the black colour showing through on the vertex of the head, 

 as a broad interrupted subapical fascia on the posterior border of 

 the pronotum, and as bands on the posterior margins of the 

 segments of the abdomen ; wings fusco-hyaline, with a broad 

 apical fuscous margin, the disc yellowish, the nervures and tegulae 

 testaceous ; the intermediate femora narrowly close to the apex, 

 and the apex of the posterior femora and tibiae blood-red.
