brown in anterior half, posterior half black, fused with wide posterior-angle 



291 process; posterior margin light in middle, yellowish laterally, r-eddish 

 brown in middle of each half. 



Tergites of metathorax distinct, with black setae; anterior sclerites fused 

 into an elliptical, transverse, median sclerite with a light, milk white, longi- 

 tudinal stripe, and with blackish brown, lateral setose parts; posterior 

 median sclerites large, triangular, blackish brown (Figure 512, C); lateral 

 sclerites mainly yellowish, the anterior, setose parts blackish brown, with 

 2—3 dark dots; median side with a row of 6—7 dots on dark background; 

 transverse band consisting of oblique, blackish lines, and a reddish dot. 



A distinct character of this species is the presence of a light stripe 

 lateral to coronal suture, which continues in a light median stripe on 

 pronotum, mesonotum, and anterior tergite of metathorax; forming a distinct 

 dorsal stripe on head and thorax. 



Prosternite in form of a small, yellowish, irregular sclerite, with small, 

 dense, pinkish dots near its base; horn relatively short, wide at base, dark 

 brown; light apically and slightly bifid. Mesosternite represented by a row 

 of large, dark brown, sclerotized dots, and small, brown sclerites with dots 

 laterally. Ventral side of metathorax with 4—6 large, pinkish, or lighter, dots 

 laterally (Figure 513). 



292 Legs chestnut brown, with broad, blackish, distal bands on all tibiae and 

 tarsi; coxae and femora with indistinct punctation; ratio of length of legs 

 62:100:96.

Fore femur long, with slightly convex dorsal and almost straight ventral 

 side. Primary ventral setae of fore femur in form of 2 pointed, light 

 yellow, large spines, basal spine slightly smaller than apical; posterior seta 

 thin, dark, short, slightly shorter than distal ventral seta of trochanter, and 

 situated nearby or dorsal to basal spine. Primary ventral setae of mid- 

 leg brown, moderately long, strong, about the same size, situated in middle of 

 segment and further basally. Primary ventral setae of hind leg represented 

 by a similar strong, moderately long seta in middle of segment, and a longer 

 seta further basally.
