and several short or small light setae; brown part of lateral margin with 

 several small setae and 2 moderately long setae, resembling those of anterior 

 angle. 



Mesothorax and metathorax wider than prothorax; posterior part of 

 mesonotum laterally with a short ridge separating a small lateral part; 

 raedium part much larger, with black posterior margin; surface yellow, with 

 several large dots along median suture and in a transverse row. Anterior 

 margin, rounded anterior angles, and part of lateral margin, with dense, small, 

 light setae, longer anterior -angle seta among them; surface setae in 2 

 transverse rows, an anterior row of several, small, light setae, and a 

 posterior row with numerous (21—23 according to Nielsen) large and small 

 setae behind transverse row of dots. 



Metanotum with 4 tergites, 2 single, transverse, median sclerites situated 

 one behind the other in middle, and a lateral tergite; all tergites light, 

 yellowish. Anterior tergite largest, in form of a transverse rectangle with 3 

 dark lateral spots and 2 smaller median spots near anterior margin, spots 

 marked with small light dots; lateral tergites bean- shaped, with slightly 

 concave lateral margin, light yellow, with a brownish spot at median margin. 

 Large anterior median tergite with a dense row of small thin setae at 

 411 anterior margin, several surface setae and groups of setae at anterior 

 corners behind them. Posterior median tergite with a large median spot 

 and a lateral row of setae, including a larger medioanal seta. Lateral 

 tergites with setae in an anterior group (including primary anterior-angle 

 seta) and laterally. 



Propleuron long, irregularly rhomboidal, with a wide, black ridge on 

 shorter diagonal; episternum and epimeron almost equal, epimeron with 

 a moderately long brown seta near suture; trochantin free, not fused with 

 episternum, apical seta short, brown, both setules situated ventraily. 

 Epimeron of metathorax slightly larger than on mesothorax; trochantin 

 fused with episternum, conical, with black margin and a thin, brown, distal 

 seta; epimeron with 4—6 lateral setae on mesothorax, 7—12 on metathorax. 



Ventral side of mesothorax and metathorax with large, paired, light 

 sternites, those on mesothorax with brown anterior margin. 



Legs (Figure 670) relatively long, especially hind legs, with abundant 

 secondary chaetotaxy on coxae and femora; ratio of length of legs 

 84: 100: 114; midlegs about Va of length of larva. 



Fore coxa oblong, narrower distally, like mid- and hind coxae; 

 distodorsal indentation small; dorsal groove shallow; basal margin brown 

 in some places, mainly broad and black. Numerous (2 5—28)* anterior setae 

 at dorsal margin, among them the 2 primary setae, basal and apical, dark 

 brown and strong, in contrast to secondary setae; posterior dorsal margin 

 with 5—7 setae, among them one dark primary seta; anterior and posterior 

 surface with basal groups of large secondary setae, a large, dark brown, 

 anterior primary surface seta dorsally; 2nd anterior primary seta short, 

 subapical; a large number of long secondary setae ventraily; both 

 distoventral setae thick, light brown, situated at margin, posterior shorter 

 than anterior. 



Trochanter closed dorsally; anterior surface with a subventral ridge 

 from articulation with coxa to distal end of segment; anterior and 



Number of setae according to Nielsen (1942:452).
