pair in front, and a tliird pair inwardly displaced at one-third from the suture. The 

 clear sensory pustules are minute, one on each side between but a little inside the 

 lateral bristles. The projecting part of the mesophragma is only about one-seventh 

 of the scutellum in length. Sternopleurae ventrally flattened and expanded 

 untero-laterally, the divide between the pleural and ventral areas of the sternimi 

 proper occurring along the thick ridge extending from the mid coxa to below the 

 episternite. The distance between the anterior extremities of these ridges, when 

 the sternopleurae are flattened out, is about twice (17:9) that between the hind 

 ends. Between the anterior end of the ventral ridge and the episternite one moderately 

 long weak bristle ; one at each postero-lateral angle of the sternum, and a median 

 pair both anteriorly and posteriorly at the edge about the mid line, the former 

 rather widely separated. In the middle the post-scutellum is overhung for the 

 greater part by the scutellum, the concealed part being pentagonal in shape, with 

 a broad median thickening in Ime with the propodeal keel ; the exposed part 

 consists of two narrow descending rugulose areas touching medianly. The sunken 

 side areas are bounded laterally by distmct ridges, besides being incompletely 

 divided by ridges rising from the lateral ends of the rugulose areas but fading out 

 half-way towards the sides. Propodeon broadly smooth medianly, except for one 

 or two raised cells in the antero-median angles. The keel (highly magnified) consists 

 of two closely applied ridges. From half-way between the median keel and the 

 spiracle the surface shews a strongly raised, coarse, rather thick-walled reticulation, 

 which extends on to the metapleurae. There are no pre-spiracular lateral keels, 

 but posteriorly (from one-half to the hind margin) there is a short thickened fold 

 in the chitin. Spiracle moderately large, oblong oval, lying on the edge of a distinct 

 elongate sulcus ; 12-15 bristles outside the spiracle. The propodeon is laterallv 

 ridged and expanded, with the postero-lateral angles right angles, and the sides 

 a little convexly convergent. 



Thoracic sculpture. Pronotum with the reticulation decided and raised, cells 

 of moderate size, quadrate or pentagonal, mainly oblong-transverse, the largest 

 and most feebly marked antero-ventral. Prosternmn with the somewhat large 

 cells radiating antero-laterally from the mid hue. Mesonotal pattern finer, nearly 

 everywhere regular (coarser anteriorly on the mid lobe and laterally on the 

 scutellum) ; all the cells with slightly thickened raised walls, hexagonal. On the 

 sternopleurae the pattern is rather faint, except on the postero-median half of 

 the mesepimera, where there are a number of coarse raised cells in an irregular 

 patch, with one or two striae above and some incomplete cells towards the mid- 

 coxae ; otherwise the epimeron is smooth, i.e., the femoral impression is posteriorly 

 gleaming. Below the forewing the upper portion of the episternite is weakly, 

 finely striate, nearly smooth. The rest of the sternopleurae shew a regular 

 moderate reticulation, more pronomiced on the sides of the thorax, with a small 

 smooth spot (behind one-half) on the rounded edge immediately below the 

 incrassation from the mid coxae. The prepectus has a coarse delicately impressed 

 reticulation. 



Wings. Forewings (fig. 7, b) very broad, the length only a little over twice the 

 breadth; length 1'25 mm., breadth "57 mm. Hind wings about 3| times as long 

 as broad, length "98 mm., breadth "27 mm., deeply concave on basal one-third of
