 the body somewhat rhomboid, with rounded fore and side-corners. 

 Dorsal side (Fig. 51). There is one dorsal shield somewhat rhom- 

 boid with rounded corners. It is provided with pits about as 

 follows: in top one large pit, foliowed by 3 large pits; in the 2d 

 half of the shield 4 large pits on a trausverse row, then nearly 

 on the level of the stigmata 4 smaller pits in a line bowed 

 forward; then two smaller pits, and finally one oblong median 

 little pit. Between the large pits there are scattered symmetrically 

 smaller pits. Further there are 11 pairs of sense organs. The shield 

 is surrounded quite anteriorly by one pair of hairs, anteriorly and 

 obliquely sideward by 3 hairs on each side, quite sideward by 

 one hair, between the shield and the stigma by one hair, and 

 behind the stigma by about 9 hairs on each side. The stigma is 

 quite dorsal. The peritrema runs forward and outward and beuts 

 then ventrally.

 features: there is an little jugular shield; the piriform sternal shield 

 is small with its top forward, and somewhat tapered head back-

 edges of the coxae 3 ; it bears 6 little hairs and behind the genital 

 aperture a chitinization like a V. Behind this shield and the coxae 

 3 and 4 there are 4 to 6 minute hairs. Between the coxae 4 

 there are 3 pairs of little hairs. The anal shield is small, only 

 with 2 little hairs. The peritrema runs a little inward, and before
