331 Sclerites and setae of cardo as in G. p i 1 o s a. Sclerites of submentum 

 (Figure 572, B) also similar, in form of long, brownish rectangles, but more 

 widely separated, with a small, intermediate, triangular sclerite at anterior 



margin. Stipes brownish, without 

 dark, lateral spot, in contrast to 

 G. p i 1 o s a; setae of stipes and sub- 

 mentum as in G. p i 1 o s a. 



Pronotum (Figure 573, A) as in 

 G. p i 1 o s a but darker, reddish brown, 

 3^ellowish brown in anterior third and 

 on median hump; surface of hump with 

 long, conical tubercles, 2 pairs of dark 

 brown dots, a 3rd pair paler. 



Mesonotum (Figure 573, B) darker 

 than in G. p i 1 o s a, dark chestnut 

 brown; lateral tergite slightly larger, 

 with more distinct transverse ridge; 

 strongly sclerotized middle of median 

 tergite smooth, in contrast to 

 G. p i 1 o s a, without small tubercles 

 except at anterior margin and along 

 median suture. Mesopleuron, like 

 tergites, chestnut brown, its form as 

 in G. pilosa. Tergites of metanotum darker and more distinct than in 

 G. p i 1 o s a, chestnut brown; in contrast to G. p i 1 o s a and as in the genus 

 Silo, there is a small 4th sclerite at anterior margin between median and 

 lateral sclerites (Figure 573, C). 



Prosternite: represented by a narrow, transverse, dark brown stripe; 

 horn short, brownish. 



Legs darker than in G. p i 1 o s a, brown, similar in size and form; fore 

 coxa slightly less long, in contrast to G. p i 1 o s a; femora and tibiae 

 slightly dark dorsally, tibiae dark dor sally in distal part; femora with 

 indistinct, light dots. Chaetotaxy as in G. pilosa (Figure 574). 



Lateral line from beginning of segment 3 to end of segment 8; hairs 

 longer at posterior margins of segments 7—8 than elsewhere. Gills with 

 2 or 3 filaments, on segments 2 — 7. 



Tergite of segment 9 indistinct, whitish, thin, v/ith minute spinules at 

 margin; setae pinkish brown, medioanal setae slightly darker, moderately 

 long, anterior-angle setae longer but thinner; 2 setae between medioanal 



332 setae; 3—4 primary and secondary setae, including a moderately long, 

 intermediate seta, situated between medioanal and anterior -angle setae. 



Area "b" of anal legs pale, weakly sclerotized, mainly white on dorsal 

 side, golden brown distally, light brown laterally and ventrally, with narrow, 

 blackish brown, distal margin; median distal seta and neighboring seta black, 

 thick, of equal length; lateral seta dark, thinner, much shorter; median 

 subapical seta brownish, thin, moderately long, ventral seta similar but 

 darker. Sclerite "c" yellow, with sparse, small spinules, with straight, 

 black lateral margin; seta yellow, relatively large. 



Claw light brown in basal half, covered with small spinules; apex reddish 

 brown, with a yellow dorsal denticle. Seta 1 situated near base, short, light
