Gen. AMCEB^A. 



Mentum and ligula as in Ega ; penultimate joints of palpi bristling 

 with long hairs, ultimate ones very sharp, the labial one somewhat 

 fusiform; mandibles long, sharp; labrum short, transverse; head 

 and neck of Ega, the latter part not so long ; antennae with the 

 five basal joints slender, and the four apical ones gradually thickened 

 and nearly twice as thick as the basal ones ; the four basal joints are 

 glabrous and the others densely pubescent, but the seven basal joints 

 bear inwardly only four or five long setae at the tip, as in Lastocera ; 

 prothorax as in Gasnonia ; body pedunculate ; elytra convex, sinuate 

 laterally below the humeral part, truncate and slightly sinuate behind ; 

 legs very long and "slender ; claws not pectinate. 



The facies is that of Ega, but it is easily distinguished by the 

 fusiform shape of the labial palpi, by the basal joints of antennae 

 ciliated inwardly, and by the thickening of the four apical joints. 



Amoeb^a mashuna. 



Black, subopaque ; palpi black ; the four basal joints of antennae 

 slightly infuscate, the other three albescent, and the four apical ones 

 black ; basal part of the femora and the tibiae w^hitish ; head closely 

 plicate, pilose underneath, narrowed behind into a long neck, and 

 having on each side a long seta in a line with the supra-orbital ones ; 

 prothorax narrow, elongated, attenuated in front and less so behind, 

 convex and a little swollen in the median part, plicate transversely, 

 the folds rugose and closely set, faintly grooved in the centre and 

 with a lateral series of long, stiff black bristles ; elytra with the 

 humeral part sloping diagonally, convex, sinuate below the humeral 

 angle, slightly ampliate at the median part, and not much attenuate 

 from there to the apex, which is truncate and a little sinuate ; they 

 are deeply striate, Vv^ith the intervals very finely shagreened and with 

 a series of long, stiff, black bristles in the alternate striaB ; are dull 

 black with a transverse, sub-basal, narrow, yellowish band extending 

 from the second stria to the outer margin, a line of the same colour 

 extending longitudinally on the second interval from the median part 

 to the top of the posterior declivity, a shorter one on the fourth 

 interval, and two supra-apical spots on the fifth and sixth intervals 

 respectively : these two last spots are missing sometimes, but when 

 they exist they coalesce with the apical part of the yellowish line on 

 the fourth interval. Length 5^-6 mm. ; width 2 mm.
