Antennal bristles conspicuously stout ; segments VIII and IX each with a ventral bristle. 

 Terminal segment with 3 preapical bristles, the dorsal of which slightly shorter and at a greater 

 distance from the apex, two capitate subapical sensory setae, and one apical hair-like seta. 



Thorax : 555-737 (608).) jjl long. Prothorax : Pronolal ridges medially interrupted at a 

 weakly sclerotized point. Lateral pronotal sclerites and post-lergites comparatively large. 

 Dorsal margin of proepisternum ridge-like. Prosternum triangular, 31-46 (37) [j. long ; 

 posteriorly supported by a transverse, 107-128 (1 13) (J. long prosternal ridge. Prothoracic setae 

 on each side of the median line : Medial pronotal setae 2-3 (2-6) ; lateral pronotal setae 2-4 

 (2-9) ; post-tergilal setae 0-3 (1-4) ; antespiracular dorsal setae 2-4 (3-1). One antespiracular 

 ventral seta and one prosternal seta always present. Prothoracic pores on one side : Medial 

 pronotal pores 2-6 (3-2) ; lateral pronotal pores 1-3 (i-8) ; antespiracular dorsal pores 0-1 (0-5). 

 Prosternal pores absent. 



Mesothorax : Prescntum 92-113 (98)^ long and 128-165 ( I 47)( A wide (ratio 1 : 1-4-1-6, av. 

 I- 5) '• prescutal ridge well developed and prescutal suture distinct. Scutu»i heavily sclerotized 

 antero-laterally, with a median longitudinal narrow membranous area ; 116-156 (i3i)(x long, 

 i.e. the ratio lengths of prescutum to scutum 1 : 1-2-1-4 ( I- 3)- Prealare, prealar ridge, triangular 

 plate, anterior and posterior notal wing processes well developed. Scutellum pentagonal, 49-64 

 (58) [i. long and 101-131 (ii6)(a wide (the ratio being 1 : 1-9-2-2, av. 2-0, and the ratio its length 

 to the length of the scutum 1 : 2-1-2-6, av. 2-3). Poslalare with well separated anterior and 

 posterior postalar ridges. Postnotal apophysis strong. Mesopleuron : Mesopleural ridge
