 and convex anterior margin, nearly contiguous with the hind margin of the 

 body, and with two pairs of hairs inserted as the fig. 58 shows. 



Epimera I — III with well chitinized apodemata between them; apodema 

 between epimera III and IV short and the hind margin of epimeron IV, which 

 is twice as large as the others, is curved but not very well defined. Sternal 

 hairs very small, two on epimera I, one on epimera II and III and two on 

 epimera IV. Behind epimera IV one pair of small hairs and on the venter 

 two pairs of slightly longer hairs, the anterior pair near the centre, the posterior 

 half way between the centre and the periphery. 



The legs (figs. 55 — 57) are darkly brown-coloured, with clavate femora
