on the dorsal part, glabrous, but having an outer marginal, 
normal fringe of yellowish ciliw, 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, 
frmged with somewhat long hairs, drawn inwards; abdominal 
segments and femora very hairy; pectus very densely 
pubescent.

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; maxille bearing a few rigid hairs along the inner 
margin, straight and laminate at the apex, but having one or two 
rigid sete 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; genz strongly developed, 
sub-parallel, eyes only moderately large; antennz 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 cox broad parallel, hind femora swollen, 
hind tibia not longer than the femora, broadly dilated at apex ; tarsi 
long, slender, claws long, very slender, simple; anterior tibiw 
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 Tulbaghia 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.
