EPARCHUS. 193 



tubercle, projecting at right angles to the body ; those on segments 

 six and seven are always the strongest ; in the female there are no 

 traces of these tubercles. Last dorsal segment of c5' typical, 

 strongly attenuate, very strongly sloping, smooth, with two blunt 

 elevations above the roots of the forceps. Penultimate ventral 

 segment almost entirely covering the last ventral segment, 

 rounded. Pygidium of S short, blunt, obtuse. Porceps of cj' with 

 the branches subcontiguous at the base, fairly stout, and gradually 

 converging; quite near the base, on the upper surface, there is 

 on each branch a vertical knob, blunt and rounded at the apex 

 and thicker there than at the base; from this point, the 

 branches curve outwards and then inwards, thus enclosing an 

 oval space ; the inner margin is finely crenulate and towards the 

 apex there is a sharp short tooth ; in the $ simple, straight, 

 slender, and unarmed.

Variation. — There appear to be two well-marked forms of this 

 species; in one, apparently the typical form, the general colour is 

 deep dark red, \^■ith the wings almost entirely yellow, with very 

 faint dark markings, or with none, the abdomen having three 

 lateral tubercles on each side, and the autenniB with a paler ring 

 near the apex. This is the form described by de Bormans from 

 Burmese specimens. In some specimens taken in Java by Eouyer, 

 the whole colour is black, the dark oblique band of the wings has 

 swamped the yellow, leaving only a tiny orange dot at the base of 

 the suture and exteruo-apical corner of the wing ; the elytra are 

 very deep red, almost black, but always paler at the shoulders. 



Sometimes the antennae have one or two pale segments before 

 the apex. 



The species is easy to recognize by the vertical processes on the 

 upper surface of the forceps of the male, near the base ; these are 

 clubbed and perfectly round on the top.
