vertical bristles, dark brown in colour, projecting forwards, and 

 three or four post orbitals. 



Antennae w T ith the basal segment brown, the inner and upper 

 faces rather densely clad w 7 ith creamy spindle-shaped scales ; the 

 second segment is a dirty white at either end and black in the 

 middle ; the verticillate hairs are inserted about the middle, and 

 are very short except on the inner face ; there is a tuft of long 

 creamy yellow scales on the inner face ; other hairs are inserted 

 near the base, and there is a whorl of short stiff bristles at the 

 end of the segment ; the succeeding segments are black at the 

 apices and at the insertion of the verticillate hairs, and dirty 

 white between their immediate bases ; at the apex of each 

 segment except the last there is a whorl of short stiff hairs. 



Clypeus naked, dark brown. 



Palpi of five segments ; first segment short, swollen and con- 

 stricted in the middle; second segment longer, linear ; third about as 

 long as the first two, rather swollen at the apex ; fourth segment 

 about one-third the length of the third ; fifth minute but quite 

 distinct. The whole palp is about two-thirds the length of the 

 proboscis ; it is black scaled except for some white scales on the 

 upper surface of the first segment, a ring of white scales at the 

 apex of the second, third and fourth segments, and white scales 

 over the whole of the fifth segment. Proboscis long, black scaled 

 over the first half, then there is a band of creamy scales extending 

 about twice as far on the under surface as it does above ; beyond 

 this above are black scales and white and black again at the 

 immediate apex ; label lae creamy yellow. 



Prothoracic lobes black, not prominent, covered with white 

 narrow-curved scales above and with broader, almost spindle- 

 shaped white ones below. 



Metanotum dark grey, almost black, covered with narrow- 

 curved scales, black, tawny and white in colour, arranged in a 

 sort of pattern. The anterior margin is covered with white 

 scales, followed laterally by tawny scales ; dorsally in the centre 

 is a line of white scales running about half-way across the meta- 

 notum and ending opposite a diamond-shaped patch of tawny 

 scales edged with a few black scales set in a bare space which 

 appears as a black margin ; flanking the median line of white 

 lies on either side is a line of tawny scales, and outside this 

 line is a patch of white scales anteriorly and a bare space having 



appearance of a black spot owing to the dark colour of the 



tanotum ; the posterior part of the thorax is chiefly occupied
