on the dorsal part, glabrous, but having an outer marginal, 

 normal fringe of yellowish ciliae, covered with closely set, equi- 

 distant round punctures, and having no costule or stria, not even 

 a juxta-sutural one ; pygidium as broad as long, sparingly punctate, 

 fringed with somewhat long hairs, drawn inwards ; abdominal 

 segments and femora very hairy ; pectus very densely 

 pubescent. 



Female unknown. 



Length 9^ mm. ; width 5J mm. 



Hob. Transvaal (Pretoria). 



GAMKA, n. gen. 



Mentum parallel, very deeply and broadly emarginate in the 

 anterior part with the angles rounded, condyle of labial palpi almost 

 lateral, elongated, sunk in the cavity and very short, like the second, 

 the apical one moderately long, swollen outwardly, straight inwardly, 

 obtuse at tip ; maxillae bearing a few rigid hairs along the inner 

 margin, straight and laminate at the apex, but having one or two 

 rigid setae set at right angles to the upper margin, the inner lobe is 

 seemingly fused with the upper, last joint of maxillary palpi longer 

 than the other three taken together, and plainly fusiform ; labrum 

 sub-horizontal, somewhat long, vertical at apex and plainly emar- 

 ginate in front ; clypeus truncate in front, with the angles very 

 little rounded, separated from the head by a fine keel, the latter 

 without a transverse ridge on the vertex ; genae strongly developed, 

 sub-parallel, eyes only moderately large ; antennae 10-jointed, club 

 6- jointed, arcuate, joints very long, laminate and all of equal length 

 prothorax with the anterior margin arcuate and not hairy, moderately 

 •convex and fringed laterally with long bristles, base slightly bi-sinuate 

 posterior angles rounded ; scutellum ogival ; elytra sub- cylindrical 

 projecting beyond the pygidium which is drawn in, abdominal seg 

 ments very narrow, hind coxae broad parallel, hind femora swollen 

 hind tibiae not longer than the femora, broadly dilated at apex ; tarsi 

 long, slender, claws long, very slender, simple ; anterior tibiae 

 bi -dentate outwardly, inner spur long, slender. 



The small insect included in this genus differs from all the South 

 African Pachypodini in the great horizontal development of the 

 labrum ; it is not unlike Tulbagliia cereris in general appearance, 

 but is at once differentiated from the Tribe Ablaberini by the 

 position of the spurs of the hind tarsi, and the presence of a 

 labrum.
