Behind the dorsal shield there are two unequal pairs of little hairs. 



On the ventral side (Fig. 42) a large jugular shield, an oblong- 

 rhoniboid sternal shield and a little anal shield are discernable. 

 Behind the sternal shield 9 pairs of little hairs. Close to the posterior 

 angle of it there are two spots where the skin is stronger chitin- 

 ized, most probably these chitinizations serve to the attachment 

 of muscles. 



Male. — Length 720 p. — Dorsal side (Fig. 43). There is 

 one dorsal shield, with the 3 median and 6 pairs of symmetrie 

 pits. — The stigma is dorsal. — Behind the dorsal shield there 

 are two pairs of small hairs. — Ventral side (Fig. 44). No jugular 

 shield; the sternal shield is rather small and beautifully shield- 



Female. (Fig. 45) shows us the dorsal aspect of a virginal female. — 

 lts length is about 800 ft. — The dorsal shield is rhomboid with 

 rounded angles, and a sinuation outward about the shoulders. The 

 hairs which surround the dorsal shield, are small. Except the four 

 small hairs behind the dorsal shield there are two strong bristles 

 quite on the posterior margin. Stigma lateral. Ventral side (Fig. 46). 

 There is a jugular shield, two pairs of minute intercoxal shields, 

 a broad-piriform sternal shield with 3 pairs of minute hairs, a 

 small genital shield with one pair of minute hairs, and an anal 

 shield. Except the usual 9 pairs of small hairs between the genital 

 and the anal shields, there is one pair of strong bristles quite 

 on the posterior margin. There is a real but small abdomen, 

 distinctly demarcated from the thorax. The real genital aperture 

 is a transverse split between the sternal and genital shields; by 

 the transparency of the genital shield the vagina is discernible. 



Fig. 47 represents the dorsal aspect, fig. 48 the ventral side 

 of a pregnant female. lts length is about 1015 f*. — The demar- 

 cation between the thorax and the abdomen has vanished.
