 light median seta; galea short, in form of tubercle with large sensillae; 

 palp short, segments of about the same length, 2 proximal segments with 

 open, dark sclerites, and much wider than the following 2 segments; 3rd 

 segment with dark lateral spot; 4th segment light, with large sensillae. 



Mentum in form of a narrow, transverse ring with a dark black stripe; 

 ventral sclerites oblong, brown, seta brownish, subapical; palpiger large, 

 horseshoe-shaped, brownish; labial palp yellowish, with large sensillae. 



Pronotum (Figure 137) with projecting anterior margin; anterior angles 

 rounded; surface yellowish, with indistinct, light brown pattern consisting 

 of a longitudinal median stripe along the suture and curved stripes in each 

 half; anterior margin broad, with pinkish brown stripe; anterior margin 

 with a dense row of blunt, thick, and smaller, pointed, light spines; posterior 

 margin broad, with a narrow black transverse stripe, interrupted in each 

 half; process of posterior corner large, reddish brown, with broad black 

 margin; surface with light brown, distinct dots, smaller along the suture, 

 large, round and oblong in each half and in posterior area. . Sclerite with 

 primary and secondary setae, except in the punctate posterior area; 

 secondary setae spiniform, thick, short, and small, black and light, and 

 several, thin, short, setae; primary anterior -angle seta black, moderately 

 long, at some distance from the margin; medioanal seta longer; intermediate 

 seta slightly shorter than the anterior -angle seta; the other 2 setae situated 

 among secondary setae. 



Mesonotum smaller than pronotum, each half of about the same length 

 and width; color chestnut brown, yellowish in the posterior angle with a 

 reddish brown, oblique stripe; anterior margin with black stripe in iniddle; 

 lateral margin broadly black; process of posterior corner with large, 

 round, light spot; posterior margin laterally with a narrow brown area. 

 Dots large, light; each half of tergite with a pair of indistinct small dots 

 near suture. Secondary setae black, short, and small, thick, less numerous 

 than on pronotum, absent on the posterior angle; anterior -margin primary 

 seta moderately long, situated in the middle; anterior -angle seta long, 

 situated some distance behind the angle; medioanal seta situated in 

 posterior area, thinner than the others. 



Tergites of metanotum of the anterior median pair smaller than those 

 of the posterior pair; both pairs small, grayish brown, pale, with irregular 

 Outline; setae black; anterior -margin primary seta of first pair of tergites 

 thick, long, flanked by several secondary setae; medioanal seta of posterior 

 pair long, thick, their intermediate and lateral setae smaller, and few 

 secondary setae; lateral sclerites m.uch larger than median sclerites, 

 oblong, dark brown, with wide, almost straight lateral margin. 



Dark transverse stripe replaced by a large spot and light oblique 

 streaks; setae restricted to apical area; primary anterior -angle seta 

 long, thick, subapical near an almost equally long secondary seta; the 

 other 10—11 secondary setae short or small. 



Propleuron in form of small, oblong sclerite with deep, black suture 

 groove; epimeron reddish brown, with wide black basal margin and narrow, 

 dark brown, apical margin; a black seta near the suture; episternum dark 

 brown; trochantin with small black sclerite, seta strong, black, setules light.
