Segments I-VII : tergiles on segmenst 1 1 — I II represented by 3 small sclerites on .interior 

 margin — one medially and one on each side, on segment IV by a small sclcnte on each side, and 

 on VII by a weak transverse plate ; sternites represented 1>\ a weak transverse plate on segments 

 II, III and VII, and sometimes by a small weak sclerite on each side on IV and VI, Caudal 

 extension of segment VII large, extending beyond level of posterior margin of segment VIII, 

 tapering, weakly sclerotized lateroventrally. Dorsal setae : a few (up to 4) f.s. occasionally 

 present ; usually one h.s. on each side on segment I and each of I V-VI I but none on II ami 111
