Bcllardia siiiicHS, described by Bigot from one specimen from 

 China, is from the description no doubt this species described by 

 Walker and others , the type is probably now lost. 



This species has certainly a great resemblance to Tab anus 

 autumnalis , L., but may be distinguished from it by the closed 

 first posterior cell, and even in these specimens with this cell not 

 closed but very narrow, the narrower abdomen and smaller size 

 of insect, the narrower forehead seven times as long as it is wide 

 (in T. autiimnalis it is only five times) and the frontal callus nearl}^ 

 reaching the eves will serve to distinguish it.

 spots apparent, on each of the 3 — 5 segments a whitish yellow 

 triangular median spot which (?) takes up the whole hind border 

 with its broad base, and reaches the fore border with its apex, 

 the side borders also whitish ., extending on each segment a little 

 inwards, the segmentations narrowly red-yellow ; under side black- 

 ish with yellow sides and segmentations, in certain lights it 

 appears wholly white with the exception of a broad middle stripe.
