I refer this species to Bermatodes, an Eastern genus, rather 

 than to StigmatracJielus, an African one, on account of the scaly 

 corbels of the posterior tibiae, the principal distinction between 

 the two genera. The length of the scape is sometimes dependent 

 on sex ; it may be that the other sex of this species ( $ ?) has the 

 shorter scape of its congeners. 



Pamph^a. 



Dermatode affinis. Scapus partem posteriorem oculi attingens; oculi 

 parum prorainentes. Prothorax basi rectus. Propectus brevissimum. Pro- 

 cessus intercoxalis angustior. Abdomen segmento secundo tertio quartoque 

 longiori ; sutura prima arcviata. 



In Dermatodes, and indeed in every large genus, these and 

 every other character are subject to excej)tions ; but here, taken 

 together, they constitute a sufficiently well-marked genus. The 

 straight base of the prothorax and a corresponding straightness 

 at the base of the elytra are perhaps the most prominent cha- 

 racters. The comparatively non-prominent eyes are accompanied 

 by a narrower head ; while in the more typical Dermatodes the 

 prominence of the former is so exaggerated as, in some species, to 

 be semi-pedunculate. The species described below is covered with 

 approximate white hair-like scales ; but with the derm showing 

 between them, the coloration appears to be a pure pale grey.

ITab. Mayotte. 



Narrowly oval, pitchy, everywhere clothed with white approxi-

 front ; antennae ferruginous, the two basal joints of the funicle 

 equal, the third to the fifth gradually shorter, the last broadly 

 triangular, club elliptic ; prothorax slightly transverse ; elytra 

 broader than the prothorax at the base, the sides on the basal 

 half nearly parallel ; fore tibiae denticulate on the inner margin.
