Ph. camerunensis Tullgr. n. sp. (Pl. 23, fig. 7 a, b). 

 A single female from Itoki ( 5 /i 1891). 

 Female. — Black; yellow are the following parts: the 

 clypeus and a large spöt on each side of that, the outside of 

 the mandibulffi, a broad band at the hind-margin of the prono- 

 tum, a small spöt on the tegulse, a broad band on scutellum 

 and postscutellum, two small triangulär spöts on the median 

 segment, the two anterior pair of tibia beneath. The abdo- 

 men is nearly perfectiy red-brown. The wings subfuscous. 

 The hairs black, light reddish on the abdomen. 



The clypeus very broad. The lower margin in the middle 

 strongly arcuate. Above this projection a corresponding 

 upper one, that is at the apex straightly truncated, and on 

 each side of this a small emargination. The side-parts of the 

 clypeus very narrow with rounded apex. The middle-part is 

 a little convex and with a short transverse impression below. 



The eyes touch the base of the mandibulee, very conver- 

 gent and emarginated in the upper half. The longest inter- 

 val between the eyes on the vertex nearly as long as the 

 joints 2—6 of the flagellum. The interval between the poste- 

 rior ocelli much shorter than the distance from the eyes. 



The antennae comparatively thick; the second joint of the 

 nagellum much narrower at the base than at the apex, about 

 as long as the third and the half of the fourth joint. 



The front very closely and finely striate and punctnred; 

 the vertex sparser punctured and not striate. The clypeus
