This is a distinct species from the above and from C. fascia- 

 tus, having the second black band on tlie second segment 

 extending to the sides and continuing upwards^ thus joining 

 the first band, so that a wide triangular space of the yellow 

 colour is left between the tMO bands. The face is shining 

 black, with a very short yellow stripe in the centre.

The type (a female) is merely labelled " China" ; there is 

 also a male specimen from Haining, Chekiang, China, 93. 52 

 {Walker). 



Neither of the specimens is in good preservation ; in 

 their general appearance they have more resemblance to the 

 species of the Paliearctic Region, but do not seem identical 

 with any of the described species, so that they are included 

 among those of the Oriental Region for the present. 

 $ . Black. Face and antennae yellowish. 



Face yellowish ; the callosities which reach to the proboscis 

 are tawny; the cheeks black, covered with yellow tomentum, 

 leaving only a round black shining spot apparent on the border 

 of the eyes. Pal})i yellow. Antenuse yellow; the third joint 

 is wanting (Walker says it is black at the tip). Forehead 

 yellowish, with the usual black tubercles. Thorax black 

 (probably denuded of grey stripes). Abdomen black, the 

 first segment yellow^ at the sides ; the second yellow, with a 

 black spot (shape indistinguishable) in the centre ; the third, 

 fourth, and fifth segments black, with yellow posterior 

 borders, which attain in the centre to triangular spots ; there 

 is a trace of a yellow spot on the sides of the third segment ; 

 the pubescence seems chiefly yellow. Legs yellow, knees 

 darker. Wings with the usual band and apical spot; the 

 shape of the former is somewhat peculiar, projecting on its 

 outer border towards, but not attaining, the fork of the third 

 vein ; in the first posterior cell it becomes concave, then 

 slightly convex till it reaches the fifth posterior cell, where 

 the sinus is not very marked, and follows the fifth vein ; it 

 is narrow in width, only filling the discal cell, not en- 

 croaching on the basal cells at all, and filling the fourth 

 posterior about halfway up ; the basal cells have only dark 

 shading at their extreme base ; the apical spot is the same 

 Midth throughout, only crossing the anterior branch of the 

 third vein at its apex. 



In the male the upper half of the facets of the eyes is 

 larger and there is a well-marked dark band across and an
