white line, shaped Hke a long thin wedge, its base resting rather 

 obliquely on the anterior margin of the synthorax. In addition 

 there are traces of a second line of the same colour close in front 

 of the humeral suture, most readily distinguished at its upper 

 end. The mesepimeron, bordered with black along the humeral 

 suture, is brown-orange in colour with a large oblong-oval island 

 of black enclosed. The mesepisternum and metepimeron are also 

 brown-orange, the suture between them marked with black at its 

 upper end. 



Ventral surface reddish-brown. 



Abdomen: The first six segments are reddish-brown, the last 

 four black. The anterior segments are darker above than on the

 pair, closely approximated and parallel ; distant from the upper 

 pair, slightly curved upwards. Both pairs black.

 latter does not show the specialization in shape found in the male,
