It is iu too poor preservation to make it possible to supple- 

 ment the original description.

The type is not to be found in the British Museum Collec- 

 tion, but only the variety. Col. Yerbury has a note on one 

 of the specimens to the effect that the species is " Rare." 



Tvpe (var., female) from Sarawak, 68. 4 (Saunders). 



Two from Sandakan, Brit. N. Borneo, 98. 38 [D. Cator), 

 and one, ditto, 95. 134 ; one from Singapore, 96. 114 (Flower) ; 

 one from Sarawak, 56. \i (Saunders) ; two from Trincomalee, 

 2. 10. 90—10. 9. 91 (Yerbury). 



Walker describes the var. " with two bands, one black, 

 the other brown.'' I should rather describe it as having 

 one black band only, on the posterior border of the second 

 segment. It is related to C.fasciotus, but distingui>hed from 

 it by the facial tubercle being yellowish brown, becoming 

 black only at its upper corners, and by the absence of a 

 second band on the abdomen ; the third segment has some- 

 times traces of black colour. The species described by 

 Roudani as C. unizonatus is a synonym of this, and not of 

 C. signifer, Walker, as suggested by Osten Sacken, who states 

 that the face in the Rondani species is yellow, which agrees 

 ■with the colouring of the face of this species (see Osten 

 Sacken, in Berlin, ent. Zeit. xxvi. p. 97).
