in basal third, then sharply bowed inwards at an obtuse angle, 

 attenuate and straight, converging to the points which are gently 

 hooked ; the inner margin near the base depressed, produced into 

 a flattened triangular projection which terminates at the end of 

 the pygidium. In the $ the branches somewhat similar, but 

 shorter ; the flattened plate is present but decidedly shorter, has 

 no teeth, and the crenulations are very feeble.

Easily to recognize by the relatively great size, the form of the 

 pygidium, and of the forceps, which differ in the two forms only 

 in degree, the macrolahia being the result of the elongation of the 

 cifdolabia, which is probably the original and normal form.

Labia pygidiata, Borm. (94) p. 387, (00-) p. 65 ; Kirhy, (04) p. 26. 



Relatively large ; chocolate-brown. Antennae with 15 segments, 

 brown, the third segment rather short and subclavate ; fourth 

 pear-shaped, almost as long as the third ; the rest about the same 

 length, all pear-shaped. Head tumid, black, sutures indistinct. 

 Pronotum chocolate-brown, a trifle wider posteriorly than an- 

 teriorly, sides straight, hinder border gently rounded, the angles 

 rounded. Elytra ample, purplish brown, densely pubescent, 

 coriaceous, about three times as long as the pronotum. "Wings 

 prominent, of the same colour and texture as the elytra, but with 

 a transverse pale yellow band just beyond apex of the elytra. 

 Legs yellowish, banded with brown. Abdomen elongate, parallel- 

 sided, reddish brown, lateral tubercles distinct ; slightly wider in 

 the middle in the $ . Last dorsal segment of S large, square, 

 smooth, with two tubercles at the roots of the forceps and a 

 longitudinal median impression. Pygidium cf <S large, broad 

 and prominent, narrow at the base, then strongly widened, 

 terminating in four depressed sharp triangular points ; the 

 median portion is tumid, the edges depressed ; in the $ the 

 pygidium is less prominent and quadrangular. Forceps of 6 

 with the branches remote at the base, rather strong, depressed, 

 elongate, gently arched, the inner margin with a double edge 

 and with a sharp tooth just beyond the middle ; in the $ the 

 branches are also straight, elongate and remote at the base, the 

 inner margin being slightly dilated in the middle to form an 

 obsolete tooth ; in colour the forceps are reddish or yellowish.
