" The paratype does not show the pecularity in hair of the penult 

 legs. The anal legs have 6 teeth on the metatarsal and 5 on the 1st 

 tarsal. Femur and tibia densely clothed beneath with spinescent setae."

 Fig. 14. — Coxopleura. Fig. 15. — Inner surface of anal leg 



Tergites : The 1st not punctured and without sulci, median keel on 

 segments 2 to 20, the keel on each segment widening posteriorly and 

 flattening out in front of the posterior border. A longitudinal sulcus on each 

 side of the keel (about half-way to the edge), extending throughout from 

 the front of the 2nd to the end of the 20th tergite. Margining beginning 

 indistinctly on the 7th, distinctly on the 12th, tergites. Last tergite (fig. 13) 

 sparsely punctured, produced and evenly rounded posteriorly. 



Sternites with two submedian parallel depressions from 3rd to 19th, 

 increasing in distinctness up to the 13th and then becoming less distinct 

 again. Last sternite narrowed posteriorly, and with slightly rounded 

 posterior end. 



Spiracles oval, with crenulated border ; on segments 3, 5, 8, 10, 12, 14, 

 16, 18, 20. 



Coxopleurae (fig. 14) with long narrow process bearing two divergent 

 terminal spines. Peres numerous and evenly distributed, pore-area extend- 

 ing to upper half of coxopleurae and reaching to the base of the process. 



Legs from 1st to 20th with 2 tarsal spurs, tibiae and tarsi unspined. 

 Anal legs with 1 tarsal spur, femur (fig. 15) dorsal inner with 2 spines and a
