granules ; the more conspicuous tubercles are situated as 

 follows : — interval 2 with a small one at the top of the de- 

 clivity, on interval 3 a small one near the base and a very 

 large one near the middle, on interval 5 a large one near the 

 base and a small one close behind it, on interval 7 a medium 

 one near the shoulder and another about the middle, on 

 interval 9 a large one about the middle, and a large one just 

 behind the shoulder on interval 10 ; near the apex a trans- 

 verse row of tubercles on intervals 3-7, those on 5 and 6 

 being elongate and the others short ; behind these is a broad 

 transverse impression. Legs rather long, with scattered 

 recumbent short white setge ; the femora rugosely punctured, 

 armed with a stout tooth, and transversely impressed exter- 

 nally near the apex ; the tibise rather slender, scarcely dilated 

 at the apex and there clothed externally with golden-brown 

 hairs, wliich form a dorsal fringe hardly as long as the first 

 tarsal joint. Sternum: the mesosternum sloping very steeply 

 and very shallowly impressed in the middle to receive the 

 apex of the rostrum, the metasternum not excavated, and the 

 space between the front coxse as "wide as the rostrum. 



Length 2|-3g, breadth 2-2^ mm. 



Assam: Patkai Hills {W. Doherty). 



A strikingly distinct species.

(J . Colour varying from black to red-brown, variegated 

 with brown, yellowish and white scales or setee ; the head 

 with fairly dense narrow white scales; the prothorax with the 

 entire sides and lower surface bearing close whitish scales 

 and setse, a triangular patch of white setae on the apical third 

 of the median area (its base on tiie front margin), and some 

 pale sette on each side of the basal third of the central carina, 

 thus leaving a broad, roughly X-shaped, bare discal patch ; 

 the elytra with a very long raised stripe of scales on each 

 side of the thoracic spine extending for more than half 

 their length, the basal two-thirds being very dark brown, the 

 apical third whitish ; these scales are very closely packed and 

 obliquely raised or almost erect ; a large lanceolate sub- 

 humeral patch of dense whitish scales (continuous with 

 similar scaling on the whole lower surface), the inner edge of 

 which reaches the sixth stria at the base and extends obliquely 

 backwards to nearly the middle of the lateral margin ; the 

 apical margin and the posterior half of the lateral margin 

 with an irregular edging of white scales, and a row of 

 yellowish scales on the basal fourth of the second interval ;
