than the others, situated anteriorly, lateral to the sclerite; seta 3 light, 

 recumbent, situated posterior to seta 5; seta 6 situated more medially, 

 small and thin. 



Mandibles (Figure 184) without distal teeth; apex slightly blunt; a small 

 basal tooth only on the right mandible; transverse groove distinct; the 

 2 outer setae situated close together, the basoventral seta between them 

 dark, longer than the apical seta, which is curved and light. 



Maxillolabium (Figure 185) long. Pregula forming a broad dark brown 

 sclerite fused with the relatively light gula; submentum forming a short, 

 transverse sclerite with slightly concave anterior margin and convex 

 posterior margin; its posterior angles rounded; the setae are small, thin, 

 situated anteriorly, near the angles of the sclerite; cardo broad, resembling 

 the pregula, dark, with a small ventral seta; stipes forming an oblique 

 brown sclerite with 2 setae, a longer basal seta and a shorter apical seta. 

 Palpiger broad; apical seta of palpiger situated on a membrane at its 

 anterior angle, the basal small seta in the median corner. Maxillary palps 

 relatively long; segments 1 and 3 not sclerotized completely; the 2nd seg- 

 ment is the longest; 4th segment longer than 3rd, with small sensillae; 

 galea cylindrical; with a mediobasal notch; setae and sensillae mainly 

 concentrated on the distal membranous part. Mentum with an indistinct, 

 narrow, median stripe (Nielsen, 1942:334); ventral sclerites small, light, with 

 a short seta; sclerite of labial palpiger crescent- shaped, broad; labial palps 

 clearly marked. 



Pronotum (Figure 186) mainly light brown, with a broad, black posterior 

 margin; posterior angles of pronotum black, projecting, slightly curved 

 ventrally; posterior half of lateral margin broadly black; anterior part of 

 lateral margin with a narrow dark stripe some distance from the margin; 

 this dark stripe is hardly noticeable in light specimens; anterior angle with 

 a black spot and near it, a small light notch in the narrow dark border of the 

 anterior margin. Posterior half of pronotum with a broad dark brown spot; 

 several dots in the middle of this field, near its posterior margin; two larger 

 groups of dots in the lateral part; a curved row of indistinct dots laterally 

 on the anterior part. Two dark, thick anterior -angle setae in the light notch 

 at the anterior angle, a primary and a secondary seta which appears in the 

 2nd stage; between them a small thin seta; 3 or 4 small setae nearby, on a 

 black spot. Several small setae at the anterior margin in the middle of each 

 half; these setae are thicker than the others. The surface setae are 

 arranged in a transverse row in about the middle of the sclerite; median 

 seta longer and darker than the others; a large, dark seta near the distal 

 dark margin; a short, thick seta anterior to it, at a distance from the margin. 



Meso- and metathorax markedly larger than prothorax, broader 

 posteriorly; the anterior -angle and medioanal setae are larger than the 

 others; anterior -angle seta of metanotum small, that of the mesonotum 

 slightly longer; intermediate and lateral anal setae small and light; a small 

 thin secondary seta near the anterior -angle seta. 



Episternal-epimeral region of pleuron of prothorax with a small oblong 

 triangular sclerite whose apex is contiguous with the lateral margin of the 

 pronotum (Figure 187); a deep narrow notch separates the median light 

 part of the episternum from the other part of the sclerite, including the 

 region of the pleural suture and a narrow stripe on the epimeron; seta of 

 epimeron situated on a membrane small and thin. Trochantin with a short
