6th joint. On the exterior side slightly behind 
the apex 1 short transverse fissure (Tab. III, fig. 15, 1). 
Mandibles (in the male). 
Ist joint. 2 spread transverse and 3 longitudinal 
fissures on the distal half of the exterior side, besides

fissures, on the other 2 transverse fissures; near the 
posterior margin 3 transverse fissures on the one, 2 on

2d sternite. On each side 1 longitudinal fissure 
at the lateral margin, and from thence towards the 
median line all in all 3 transverse fissures; the inmost
