Mentum more or less ovate laterally from the base to the point of 

 insertion of the palpi, parallel thence with the outer angles slightly 

 rounded, and the apical part broadly emarginate in the centi'e, it 

 has on the outer face a deep cordiform impression reaching from 

 the apex to somewhat past the median part, and the non-impressed 

 part is covered with dense and very long fulvous setse, the apical 

 margin has a few short setae, the apical joint of the labial palpi is as 

 long as the two preceding, slightly curved, truncate at apex and 

 occasionally impressed longitudinally in the outer face ; maxillae 

 armed at the tip with three powerful hooked teeth, the two lower 

 ones of which are bifid or geminate, but connate ; the basal one is 

 sometimes distinctly trifid {A. ustulata) ; but in A. nigrovestita the 

 upper teeth are reduced to a round lobe followed by three teeth 

 disposed transversely ; maxillarj' palpi moderately long, apical joint 

 as long as the two preceding taken together, sub-fusiform, obtuse at 

 the tip, and slightly impressed laterally ; antennae nine-jointed, basal 

 joint slender for half the lengtb, clubbed thence, and as long as all 

 the three joints following ; the sixth joint is narrow, transverse, the 

 club is tri-jointed, the joints somewhat hairy outwardly, moderately 

 long, sometimes of the same length in both sexes, sometimes longer 

 in the male than in the female {A. zambesicola) ; head moderately 

 large and having very large eyes divided for about one-third of their 

 length by the canthus of the genas ; the clypeus is usually shorter 

 than the head, sometimes parallel laterally, and sub-truncate or 

 arcuate at apex, but always with the outer angles more or less 

 rounded, it is separated from the head by a transverse impressed 

 line reaching from eye to eye, and is always more densely or more 

 rugosely punctured than the head ; prothorax marginate all round, 

 obliquely attenuate laterally from about the median part to the apex, 

 sub-parallel from the median to the basal part, where it is, however, 

 always slightly broader than across the median, the basal angles 

 without being sharp are well-defined, the surface is somewhat 

 convex but very sloping in front, the base is bi-sinuate, and along the
