 arched and rather short. Frontal stripe greyish yellow but becoming 

 more brownish orange about the lower half, narrow, distinctly contract-

 times as long as its narrowest part or about four and a half times as long 

 .as its widest part ; frontal triangle slightly elevated, black but entirely 

 obscured by a greyish dust, with rather broad somewhat hollowed out 

 double lunules which are distinctly dusted with yellowish, in the middle 

 there is a narrow longitudinal furrow which extends from the frontal 

 callus to the interval space between the antennae, and this furrow is 

 inconspicuous on the ridge between the lunules just above the antennae ; 

 frontal callus shining black long and very narrow, slightly but conspi- 

 cuously elevated, expanding about lower two-thirds of the frontal stripe 

 and its Atdth occupying about the middle thirds but the lower part 

 -slightly broader so that the callus occupies about the middle three- 

 fifth of the width, the both ends of the callus inconspicuously separated 

 by a fine longitudinal furrow; pubescence on the frontal stripe rather 

 sparse, short, blackish brown intermixed with a few yellowish white 

 hairs which are more short and more depressed, the blackish one is

 cence is somewhat longer, and stouter, curved forwards and all blackish,
