and around the shields (except quite anteriorly) an unprotected 

 band of skin, especially around and behind the posterior shield. 

 The hairs on the dorsum are raore rod-like than bristle-like. 

 They stand on the usual places. On the anterior shield 4 pairs 

 of larger rod-like and distally hairy hairs (like in fig. 32), 

 and on the posterior shield one pair. The hairs corresponding 

 with the anterior and posterior large pair in the posterior shield 

 of the protonympha (see fig. 1) are not differing from the 

 other hairs in the female. On the unprotected skin aside of 

 and behind the posterior shield numerous small rod-like hairs. 

 C r i b r u m for a great part dorsal, raore or less bee-hive-shaped. 

 Ventral side. Tritosternum (fig. 33) like in the 

 deutonyrapha, but the triangular minute wings as if worn 

 out; the main trunk is slender, in its distal half suddenly 

 narrower, distally deeply split, halfway and laterally provided 

 with a narrow transparent wing, distally without wings; the 

 normal laciniae stand on little square basal pieces. Jugular 

 shields (fig. 31) small, linear, obliquely, near the coxae J. 

 Sternal shield wholly fused with the inner halfs of the 

 pedal shields, gently winged forward between coxae I 

 and II, also fused with the m et a sternal shields, but 

 the demarcation between sternal and metasternal parts is still 

 visible. Genital shield sideways fused with the ventral 

 shield; in the middle the demarcation between genital and 

 ventral part, however, is visible. Ventral shield fused with 

 anal, inguinal, outer halfs of pedal shields and with 

 peritrematal shields. Anteriorly the demarcation between 

 peritrematal and sternal shields is visible, and dorsally too 

 (fig. 30) the demarcation between peritrematal and anterior dorsal 

 shields. All the hairs on the ventral side are bristles, viz. 

 3 pairs on the sternal part, one pair on the metasternal part, 

 one pair on the genital part, 10 pairs on the ventral part, 3 

 circumanal ones, and 5 pairs on the unprotected venter. 

 Stigma on a line between coxae III and IV. P e r i t r e m a
