 all the facets ecinal ; minutely, densely, and palely pubescent. 



Tup vieir (tig. lOj. Head much rounded behind, dark 

 orange; this colour extends beyoiul tlieoeellar hump, whence 

 it is further continued in a broad line to the base of the an- 

 tenuie, the stripe narrows towards the front ; on each side of 

 it lies a silvery stri[)cof about the same width, which extends 

 right up to the boundary of the eyes. The ocellar hump is 

 in the shajjc of a tetrahedron, with much rounded angles; 

 it is deep black with conspicuous silvery ocelli arranged iu 

 an ccjuilatcral triangle round the base of the humj). 



Jruitt victc. The faceis(iuitc i)arallel-sided from below the 

 antennie, orange-yellow witU narrow silvery eye-margins ; 

 the ejiistoma is divided from the clypeus by a silver-edged 

 furrow ; the clypeus itself is eoncolorous with the face, and 

 has silvery borders and a fine silvery cross-band; the pro- 

 boscis is a little more than twice as long as the maximum 

 vertical eye-depth ; it is orange-yellow with an acuminate 

 tip ; tiie palpi are black, aljout as long as the head-depth, 

 with three or four indistinct, pyriform, somewhat hairy joints 

 of almost equal length, whicli are a little flattened in the 

 dried state. The antennie are black, except the two basal 

 joints which are very indistinctly rufous; first joint with 

 two or three long hairs outside, second long, cup-shaped, 

 others moniliform. 



Iu side view (fig. 17) the black rounded ocellar hump 

 is very prominent, the tongue below the level of the palpi 

 attenuates but little to tii). 



Tliora.v. — Tup rieiu (tig. 10). The mesothorax overhangs 

 the prolhorax in fnnit ; it is shining orange, much darker 

 iu front, with silvery reticetions on darker areas at the sides; 

 there is a minute silvery spot just iu the middle over the 

 prothorax ; the humeral calli resemble stout orange scales at 

 the front angle ; behind the dark front portion the disc is 

 paler orange down to the two ohli(iue sutures that start just 

 above the Iront of the wing-ba-es, and slope baekwarils and 

 nearly meet in the mid-line, where they end iu minute dots. 

 Just in front of these sutures the orange is again darkened 

 and silvery in two triangular patches, the hypothcnuses of
