the posterior angle sliglitly rounded ; tlie sub-margin de- 

 pressed, and the humeral extension recurved so as to over- 

 lap the base of the wing cover. Mesonotum convex, 

 narrow and short, dark chestnut brown, with a loop of 

 testaceous bounding the medial sutures extending back 

 from the base, the depression in front of the dorsah cross, 

 the exterior margin and the posterior edge of pleural 

 lobes pale fulvous, or tinged with piceous ; the cross, 

 short, abruptly elevated, it and the adjacent surface dark 

 piceous. Legs greenish testaceous, the anterior femora 

 a little infuscated above, spines and teeth and nails all 

 dark piceous, the knees and tips of tibiae slightly piceous. 

 Wing-covers long and comparatively narrow, faintly 

 tinged with bronze, the areoles generally long; the first 

 three apical ones, including the veins and cross-veins, 

 smoke-brown, veins chiefly green at base, but brown from 

 the clavus to the apex, the costal one green, bordered 

 inwardly with piceous, the first apical areole long and 

 narrow, acute at the inner end, about as long as the third; 

 the first cross-vein acutely oblique, a little longer than 

 the third, and both of them waved, the first cutting the 

 apical areole at its inner third, flaps of both wings a 

 little infuscated, Opercula short, pale, but little more 

 than one-third the length of the abdomen, narrowing to- 

 wards the tip, and rounded there ; the tips widely sepa- 

 rated by a wedge-shaped space; the drums completely 

 covered by an inflated segment, with a wide interval be- 

 tween, which is occupied at the outer end by a smooth 

 hump. The raised smooth line thus begun is continued 

 back upon the succeeding tergal segments, and from each 

 prominence a grooved line extends outwards to the 

 border of the segments. The abdomen of the male is 

 acuminately contracted at the tip, and has a short horn- 

 like process each side of the genital segment, the apical 

 ventral flap is much shorter than the segment to which it 

 is attached, it is narrowed and very blunt, rounded at tip.
