Antennal bristles much stouter than the fleshy setae ; segments VIII and IX each with a 

 ventral bristle ; segment X with two preapical lateral bristles and a slightly shorter dorsal one, 

 at a greater distance from the apex. Terminal segment also with two subapical sensory setae 

 and one apical hair-like seta. 



Thorax : 470-555 (524)0. long. Prothorax : Pronotal ridges medially interrupted by a weak 

 sclerotization ; lateral pronotal sclerites moderately large and well sclerotized. Post-tergites 

 narrow. Proepisternum with a ridge-like dorsal margin. Prosternum triangular, 31-43 (37) u. 

 long ; prosternal ridge 79-95 (85) u. long. Prothoracic setae on each side of the median line as 

 follows : One medial pronotal seta usually present, but sometimes absent on either or both 

 sides (av. o-8) ; lateral pronotal and post-tergital setae absent. Antespiracular dorsal setae 

 1-3 (2-1) ; antespiracular ventral setae and prosternal seta always one. Prothoracic disc pores 

 on each side : Medial pronotal pores 2-4 (3-2) ; lateral pronotal pores 2-6 (41) ; antespiracular 

 dorsal pores 2-5 (3-4). Prosternal pores usually 1-2, but sometimes 3 pores may occur on either 

 side or the pores may be absent altogether (av. i-6). 



Mesothorax : Prescutum subrectangular in dorsal view ; 76-89 (82)0. long and 104-122 

 (119) [i wide, the ratio being 1 : 1-3-1-6 (1-4) ; prescutal ridges well developed and prescutal 

 suture distinct. Scutum heavily sclerotized antero-laterally and with a median longitudinal 

 narrow membranous area ; scutum 95-116 (104)0. long, i.e. the ratio length of prescutum to 

 scutum 1 : 1-1-1-4 ( I- 3)- Prealare, prealar ridge, triangular plate, tegula, anterior and posterior 

 notal wing processes well developed. Sciitelhun pentagonal, 46-58 (52) u. long and 82-101 

 (92)0 wide, i.e. the ratio 1 : 1-7-1-9 (i-8) and the ratio its length to the length of scutum 

 1 : 1-9-2-2 (2-0). Anterior and posterior ridges of postalare well separated ; postnotal apophysis 

 strong. Mesopleuron : mesopleural ridge interrupted above the coxal articulation ; meso- 

 pleural apophysis, mesopleural wing process, basalare and subepisternal ridge well developed. 

 Mesepisternum, mesepimeron well-defined, and later opleurite narrow. Mesosternum : Basi- 

 sternum 128-146 (140)0, long and 156-183 (i7i)(x wide ; marginal and precoxal ridges well 

 developed ; furca strong. Mesothoracic spiracle 15-21 (18) u. wide at opening, with a 34-40 

 (37) (i. long supporting bar. Mesothoracic setae on each side : Prescutal setae 4-6 (4-6) ; scutal 

 setae 6-9 (7-5) ; scutellar setae 2-3 (2-5). Tegular setae 2-3 (2-1) ; postmesostigmatal setae 

 4-7 (5-1), occurring laterally behind each spiracle. Basisternal setae 9-14 (11-4). Mesothoracic 

 pores : 1-2 mesospiracular pores usually present behind each spiracle, but sometimes entirely 

 absent (av. 09). 



Metathorax : Metapostnotal sclerites and metapostnotal ridge distinct. Metapleural ridge 

 attenuating near the middle at the position of the metapleural apophysis ; metapleural wing 

 process small. Precoxal ridge of metathorax well developed ; metepisternum , metepimeron and 

 metasternal apophysis well defined. Metathoracic spiracle similar to the mesothoracic. Meta- 

 thoracic setae on each side : Metatergal setae 2-3 (2-7) ; metapleural setae absent ; anterior 

 metasternal setae 1-3 (2-3) ; posterior metasternal setae 0-2 (0-4). Metathoracic disc pores on 

 each side : Metathoracic pores 0-1 (0-3) ; anterior metasternal pores 0-2 (1-2). 



Wings : 1064-1162 (ii2o)[a long and 406-462 (434)0- wide ; usually with 4 alar setae and 

 occasionally 3 or 5 (av. 3-9) ; a compact row of 2-3 (2-3) minute circular sensoria also present.
