 tubercles which are smaller and sparser on light anterior area, pointed 

 in some places. Primary anterior -angle seta black, thick, moderately long, 

 thick basally, a few thin secondary setae, most of them short, brownish, 

 some of them longer; some setae dark, thicker; small, light, yellowish, 

 basally thick setae on whole sclerite; middle of anterior margin with a 

 row of small setae resembling anterior comb of spinules in Baicalinini; 

 . „_ posterior margin with brownish part covered with small, blunt, dark 



spinules and with a black posterior submarginal stripe; process at posterior 

 angle almost entirely black, fused with black posterior-angle spot. 



Mesonotum (Figure 210) dark brown in middle; anterior-margin area 

 with blackish median part; posterior and lateral areas chestnut brown; 

 surface covered with dense, dark, rounded tubercles; posterior -angle area 

 black, large, irregularly rhomboidal, smooth; oblique streak in form of 

 indistinct, narrow, dark stripe on a small reddish spot. Primary, and most 

 secondary, setae black; primary anterior -angle seta, and one secondary seta 

 large; primary anterior -margin seta and primary medioanal seta the same; 

 the other 45—46 setae differing in size, most of them thin. 



Metanotum with 7—8 thin black setae on site of anterior median sclerite; 

 posterior median sclerite represented by slightly thickened membrane 

 with a grayish spot, a long, black, medioanal seta, and 2 small, thin setae; 

 5 setae anterior and lateral to the spot. Lateral sclerite grayish anteriorly; 

 posterior part lighter, indistinct; transverse band forming a large, dark 

 brown spot with narrow, dark streaks, 



Propleuron with broad, black, pleural suture; epimeron pale yellowish; 

 tubercles darker and ^.arger at the base, a narrow black stripe near median 

 margin; seta thick, moderately long, black, situated in middle between 

 suture and distal margin. Trochantin mainly black, rounded apically, with 

 a large, grayish, primary seta; setules small, one dark, the other light. 



Mesepisternum chestnut brown, with 2 large, smoke brown dots near 

 anterior margin; similar dots basally along black, pleural suture. 

 Metapleuron lighter, smoke brown; pleural suture black, accompanied by 

 small dots. 



Legs (Figure 211 ) blackish dorsally and subdorsally; including the tarsi; 

 coxae dark ventrally; hind trochanter the same; coarse punctation on 

 the coxae, femora, and tibiae. Base of coxa with dense, dark, rounded 

 tubercles dorsally, becoming scale -shaped with serrated or spinulose 

 end subdorsally; small spinules in rows of 2—3 or singly more ventrally; 

 trochanters, femora, and tibiae with smaller, sparser, covering spinules 

 „ „. in some places. Large setae mostly black. 



Basoventral seta of fore trochanter light, spine-shaped, moderately long, 

 much smaller than posterior distoventral seta; corresponding seta of mid- 

 and hind legs long, light brown, slightly larger than posterior distoventral 

 seta; subapical ventral posterior seta of hind legs in form of large, 

 pointed yellowish spine, slightly longer than anterior ventral setae. Primary 

 anterior setae of fore femur situated close together, in form of 2 spines: 

 one of them large, pointed, light; the other yellowish, thick, shorter, situated
