128 Longicornia Malay ana. 



distinct and may be known at once by the third antennal joint being 

 very miicli shorter than tlie fourth, by its much smaller or rather 

 narrower head, especially below the eyes, and by the longitudinal 

 lines which descend in front, in form resembling the letter W ; 

 the eyes are also larger, and there is only about their own 

 length between them and the basal line above the mandibles, 

 while it is nearly twice the distance in A. sobrma. Little can be 

 said for colour in so variable a species as the former, but in 

 this the elytra are everywhere spotted or rather speckled with 

 white, while in A. sobrina the speckles only occur on the brown 

 portion or at the extreme edge of the rufous ; legs and antennae 

 less distinctly coloured ; protibiae in the male (in my specimen) 

 not much larger than in the female. 

 Length 7 — 8 lines. 



* * Prothorax somewhat toothed or projecting at the sides.
