Body, legs, and tegmina black ; a large central discal spot 

 to vertex, a broad transverse fascia to pronotum sitnate a 

 little before middle, head beneatli (excluding extreme basal 

 margin of face, which is widened into a spot between, face 

 and eyes, and the posterior margins of clypeus), and a large 

 lateral spot near each anterior coxa, ochraceons or stra- 

 mineous ; wings pale fuliginous, with darker shadings ; 

 vertex short, broad, about half as long as breadth between 

 the eyes, convexly rounded in front ; face rather broadly 

 centrally longitudinally flattened for more than half its 

 length, the lateral areas transversely striate ; rostrum 

 reaching the intermediate coxa; ; posterior tibire with two 

 prominent spines, the one nearer base smallest ; tegmina 

 very thickly, finely, and obscurely punctate, more piceous 

 than black, the posterior claval margin distinctly black. 



Long., excl. tegm., 11 mm.; exp. tegra. 30 mm. 



Hab. Cameroons [Escalera, Brit. Mus.). 



Allied to P. flavesceiis, Fabr., by the short, broad, and 

 convexly rounded vertex; by the fuliginous shading of the 

 wings allied to P. grossus, Fabr.

Body, legs, and tegmina pale ochraceous ; four small 

 spots at base of vertex in transverse series and two central 

 spots before them, two central spots near anterior margin of 

 pronotum, basal joints of antennae, a small spot near anterior 

 coxas, apex of rostrum, a broad annulation to anterior tibiae, 

 anterior and intermediate tarsi, and all the tarsal claws, 

 black ; tegmina with a small black discal spot before middle 

 somewhat surrounded by a small cluster of testaceous sufiu- 

 sions ; wings pale grey hyaline, concolorous, without darker 

 sufiusions ; vertex about half the length of breadth between 

 eyes, subangularly produced in front ; face ratlier broadly, 

 longitudinally, centrally flattened for more than half its 

 length, the lateral areas transversely striate, rostrum reaching
