 tudinal and with an oblique ridge forming a thin, reddish brown stripe as on 

 lateral tergites of mesonotum; anterior part with a large dot; setae reddish 

 brown, 4—6 in an anterior-angle group, and a row of 10—14 setae parallel to 

 ridge near anterior margin, 3—5 of these thick, long, darker. 



Propleuron reddish brown, with black pleural suture; episternum large, 

 black at anterior margin; epimeron lobed, much smaller, rounded posteriorly, 

 with a strong, dark brown, moderately long seta; trochantin dark basally, 

 384 fused with episternum, and resembling a process of anterior angle; seta 

 short, dark, subapical, setule light. 



Mesopleuron oblong; pleural suture in form of narrow, reddish stripe, 

 wide at end, blackish at distal margin; episternunn and epimeron as in 

 Figure 637, A; episternum with 3 setae, epimeron with one primary seta. 

 Metapleuron as in Figure 63 7, B; pleural suture shorter; episternum with a 

 deep indentation on median margin, epimeron with large, yellowish, ventral 

 lateral process; setae blackish brown, strong, 14 setae at distal margin of 

 episternum, 3—4 of them long, thick; epimeron with 16 setae on process 

 situated close together posteriorly, 4—5 setae thicker and long. 



Legs mainly chestnut brown, without dots; ratio of length of legs 

 50:100:96; setae large, dark, brown or dark reddish brown. 



Forelegs (Figure 63 8, A) much shorter than other legs, with short segments, 

 except for trochanter. Coxa with shallow, distodorsal indentation; primary 

 anterior basodorsal seta strong, moderately long, blackish brown; anterior 

 apical dorsal seta short, situated nearby in basal part; posterior distodorsal 

 seta situated near apex of depression, long, thin, strong; further basally and 

 apically, 2 secondary setae, one long, the other moderately long; both anterior 

 setae strong, moderately long, blackish brown, situated basally and in middle 

 of coxa; primary distoventral setae thin, moderately long, posterior seta situated 

 subventrally, lighter, brown. 



Trochanter long, yellowish; anterior seta small, tapering, posterior seta 

 short, thinner, both yellowish; anterior ventral setae, an apical and a sub- 

 apical, in form of short, pointed, yellowish spines on tubercles, 1st spine 

 shorter and thicker than 2nd; basoventral seta moderately long, strong, 

 brown; posterior distoventral seta the same, somewhat smaller; subapical 

 seta short, thin, light; light, hairlike chaetoids dense, feathered, situated 

 ventrally in distal part of segment. 



Femur chestnut brown dorsally, yellowish brown ventrally; all setae 

 primary, as on segments which follow; apical dorsal seta short, brown; 

 basodorsal seta similar but thinner; anterior seta reddish brown, situated 

 subapically in dorsal part, thick, slightly branched at apex; posterior seta 

 situated subventrally at distal margin, short, brown, strong; distoventral 

 seta situated at margin in form of a large, light yellowish spine as long as 

 posterior primary seta; basoventral seta represented by smaller spine in
