above, and a similar one on each side of the base of the prominence. 

 The width of the frons just above the conical prominence about 

 one- fourth that of the head. Proboscis brownish-yellow, dark above, 

 below, and at the sides at the tip ; labella brownish-yellow ; palpi 

 (only one joint remaining) and antennal ist joint (remainder 

 missing), brownish-yellow. Occiput, which is distinct in spite of 

 the very large flattened top of the head, dark brown or brownish- 

 yellow, a few concolorous hairs on underside. 



Thorax. — The distinct neck dark brownish-yellow or dark 

 brown, with, on each side, a narrow whitish longitudinal streak 

 above and a broader one below it, well separated from each other. 

 Prothorax well defined, dark chocolate-brown with the margins 

 pale yellowish or yellowish- white, apparently variable. Dorsum 

 of thorax brownish-yellow, two median chocolate-brown moder- 

 ately narrow stripes (separated by about the width of one of 

 them), from anterior margin almost to suture. On the outer side 

 of each of these stripes, leaving a moderately wide brownish-yellow 

 intervening space, is a large chocolate-brown spot irregularly 

 triangular in shape, bounded by the lower margin of the dorsum 

 and by the transverse suture. In this spot are two pale brownish- 

 yellow approximately oval spots, placed longitudinally, one above 

 the other, the lower one immediately in front of the wing base. The 

 transverse suture is very deep, and the linear depression connecting 

 it with the scutellum also, causing the hinder half of the dorsum 

 to apparently consist of two rather conspicuous convex portions ; 

 brownish-yellow in colour, paler anteriorly, with silvery white 

 shimmer on anterior corners and irregularly along the front margin, 

 and with a chocolate-brown transverse band irregular in outline, 

 narrowest in its middle, from the wing root to the sutural-scutellar 

 depression, which latter is almost wholly chocolate-brown 



The scutellum, which is quite small, is dark chocolate brown, 

 with a brilhant white spot on each side of the dorsum ; the 

 frenulum well developed, dark chocolate-brown. Mesopleurae 

 similarly coloured, a broad stripe on upper part, shining yellowish- 

 white, and a short smaller central brownish-yellow elongate mark 

 placed longitudinally Sternopleurae yellowish-white, with a me- 

 dian dark brown stripe from anterior margin to middle, posterior 

 to which is a round brown spot ; the lower margin of the sterno- 

 pleura also brown. The pteropleura extends from the wing 

 root to between the 2nd and 3rd pair of legs, where it takes the 

 form of a small globular piece, conspicuous, pale yellowish-white. 

 Metapleurae brownish-yellow on upper third, chocolate- brown on 

 middle third and black on lower third ; the hinder part of the 

 latter brownish-yellow. An oval, brilliant, shining white spot 

 in middle of the lower third part. Hypopleurae shining white, 

 and a similar silver white spot on extreme hinder part of meta- 

 pleurae, adjacent to the metanotum, which latter is large and 

 conspicuous, brownish-yellow, with the anterior part of the sides 

 brilliantly silvery white, and a small elongate brown spot on inner 

 side of each such white side spot.
