and the other about the middle, with three other very minute ones close to the apex, 
which has, in addition, a tuft of whitish hair on the extremity. Mouth-parts (Figs. 3, 4). 
The mandibles are short and stout, with a sharply bent apical point and a large blunt 
tooth below. The submentum is produced anteriorly in the centre beyond the junction of 
the mentum, which is consequently hidden but is heart-shaped; the ligula is very small, 
the palpi three-jointed, the two first joints beige transverse and the third longer than 
broad, as well as being slightly larger at the apex, which is uniformly rounded. The 
maxillze are armed with a few strong spines on the inside, the apical ones being curved 
inwards, the palpi are three-jointed, the two first transverse and the third cylindrical ; 
the labrum is bisinuate with some longish hairs near the apex. 
The prothorax is one-third broader than long, minutely granulate over its whole 
surface and covered (in perfect specimens) with yellow hairs; there is.a very faint median 
longitudinal line, the sides are slightly rounded and narrowed anteriorly, the anterior and 
posterior edges being straight and the latter faintly margined. The anterior legs

(Fig. 5) have the coxee nearly spherical, the trochanters very small, the femora largely 
‘dilated and furnished with a small lobe on the inner apical surface similar to that found 
in Trypodendron and other genera; the tibie are gradually enlarged apically, with strong 
bristles and one very minute spine or tooth on the inner side, otherwise they are quite 
plain; the two first tarsal joints are very short, the first nearly quadrate, the second 
transverse, the third deeply bilobed and two-thirds the length of the first two joints com- 
bined ; the fourth joint is very minute, the fifth nearly as long as the first three taken 
together.
