Bates considers the cliaracters given for this genus are in- 

 sufficient to separate it from Toxicum (Ent. Mo. Mag. x. 

 1878, p. 45), but there are four species from Japan which 

 differ from the species of Toxicum found there in having a 

 8-jointed ckib to the antenna, eyes completely divided by the 

 ocular ridge, and the absence of hair on the cephalic armature. 

 It seems to me as convenient to use the two names as to 

 divide Toxicum into two sections, as Bates has done, on tiie 

 completeness or incompleteness of the ocular carina. At the 

 same time I am aware of at least one species from India 

 which has a 4-jointed club and a complete ocular ridge, but 

 perhaps a third genus ought to be founded for these. Pascoe 

 also notices that very similar species of Toxicum have the 

 club of the antenna sometimes 3-, sometimes 4-jointed (Journ. 

 Ent. ii. p. 454). 



Anthracias duellicus, sp. n. (PI. XIII. fig. 8.) 



Elongatus, cylindriciis, niger, subnitidus ; capite thoraceque dense 

 punctatis ; elytris irregulariter striato-punctatis, utrinque paral- 

 lelis. 



L. 12-15 mill. 



Elongate, rather cylindrical, black, little shining; the head 

 somewhat coarsely and densely punctured ; the thorax bisinu- 

 ous at base, marginal edge narrow and a little produced at the 

 anterior angle ; the scutellum punctured and nearly semi- 

 circular behind ; the elytra, the stride consist of double rows 

 of irregular punctures, interstices feebly convex, parallel 

 at the sides ; the antenna? and legs piceous. Male : the 

 outside edge of the clypeus on each side is produced and 

 raised somewhat triangularly, with the apices obtuse, over the 

 eyes are two long rather slender horns, punctate, bent a little 

 outwards if viewed longitudinally, viewed sideways crescent- 

 shaped on the anterior edge ; in undeveloped males the horns 

 are short and stouter. In the female the ridge over the eyes 

 is tubercular.
