triangular, and slightly smaller than the middle spot near the frontal 

 margin. Antennae nearly twice as long as the head, reddish yellow, 

 black towards the tip ; first joint a little longer and stouter than the 

 second; second joint inconspicuously annulate; both yellow, bearing short 

 blackish pubescence; third joint much longer than two basal joints 

 together, subulate, conspicuously upturned at the tip. with five dis- 

 tinct annulations of which the basal one is shorter than the rest of 

 the third anteniial joint, and is hardly annulated, as well as it is reddish 

 yellow with blackish or brownish or brownish apical part, while the 

 last four are brownish black or brown, and are gradually shortened 

 towards the tip, but the apical one is about twice as long as the preced- 

 ing one and is blunt at the tip. 



Thorax yellowish cinereous with three very distinct narrow 

 blackish brown or black stripes, of which the middle one is about 

 half broader than the lateral ones and is gradually narrowed towards 

 the front anil pointed ; the sides of the disc somewhat broaaly orange 

 yellow, and the colour extending from the postalar calli to the humeri ; 

 a rather distinct fuscous stripe at the sides between the mesonotum 

 and pleurae, extending from the above of the prothorax to the base of 

 the wing ; humeri distinctly orange yellow, moderately convex ; 

 pubescence fairly abundant and suberect, mainly yellowish but with 

 rather numerous shorter depressed thinner hairs intermixed ; the 

 pubescence about the sides of the disc more erect, longer, moderately 

 tawny. Pleurae black, grey dusted but yellowish above, with the 

 yellowish pubescence dense and tawny on the prothorax, on the Upper 

 and hind parts of both the meso-pleurae and sterno-pleurae, and on 

 the meta-pleurae ; the pubescence on the rest of the pleurae sparser, 

 shorter and paler. Scutellum somewhat semicircular, subangulate at the 

 middle of the posterior margin, greyish yellow dusted, with an incon- 

 spicuous reddish yellow dusted patch about each side ; pubescence yellow- 

 ish and nearly erect, longer and denser than on the disc of the mesonotum. 



Wings clear, with pale brown colouring at the extreme base
