 shows some special characters. Frons slightly broader than high, 

 blackish grey, reddish above the antennæ; bristles as in projecta,

 bristles of middle row, and the lower relatively larger and not or 

 almost not more approximate. Antennæ brown. Palpi yellow, of 

 good size, but not large as in projecta, the bristles short, but much 

 longer than in projecta. Thorax yellow, the hairs at its hind margin 

 rather bristly; pleura with a blackish spot below the wing-root.
