Prothoracic setae : Medial, lateral pronotal, posl-tergital and antespiracular dorsal setae absent. One antespiracular ventral seta always present and one prosternal seta usually present (av. 08) on each side.

Scutum 43-52 (46)u. long, the ratio lengths of prescutum to scutum 1-6-1-9 (r'7) : *â Prealare, prealar ridge, tegula, anterior and posterior notal wing processes well developed. Scutellum 37-46 (40)1* long and 107-122 (t 16)jj. wide, the ratio 1 : 2-7-3-0 (2-9), and its length to the length of the scutum 1 : 1-1-1-2 (1-15) ; scutellar ridge distinct. Postalare with the anterior and posterior ridges joined. Postnotal apophysis strong. Mesopleuron : Meso- pleural ridge continuous above the coxal articulation ; basalare slender. Subepisternal ridge well developed. Mesepisternum distinct and mesepimeron small. Lateropleurite comparatively large, with an oval membranous area. Mesosternum : Basisternum 92-110 (ioi)u. long and 174-189 (180) (i wide ; antero-laterally and latero-posteriorly bounded by the marginal and precoxal ridges respectively. Furca well developed. Mesolhoracic spiracle 15-18 (17)0. wide at opening, with a 27-31 (29) (i. long supporting bar. Mesothoracic setae on each side : Prescutal setae 6-9 (76) ; sc
