segment 6. On the annulets of segments 1-5 each prescutum with 

 six short setae, each scutum with four long setae and three short 

 setae on each side, and each scutellum with 10 short setae. Segments 

 7 and 8 broad, each segment with two dorsal annulets and each an- 

 nulet with a transverse row of setae. Segments 9 and 10 narrow, 

 each with two dorsal rows of closely placed setae but dorsa not divided. 

 Raster with teges of 40 hamate setae scattered ii-regularly on the 

 venter of 10th abdominal segment, four or five long setae on each side.
