and 



tubercles are not pointed. The elytra are depressed, coarsely 

 punctured, with a raised flexuous dorsal costa; their colour is brassy green, 

 especially visible on the base and sides, the middle of the back being tawny 

 with an oblique dusky belt, sometimes absent. The antennae are much longer 

 than the body, but of the same form and proportions as in //. crista, the cilia 

 only being longer j they are dull reddish, varied with dusky.

Much more slender than II. crista, and less convex j distinguished also by 

 the absence of penicillated crests, which are replaced by obtuse elevations. The 

 general colour is pitchy or chestnut red, lighter on the antennce, and darker on 

 the undersides of the body and femora and at the apices of the tibiae ; the 

 thorax is minutely sculptured throughout, and has rudiments of three small 

 discoidal tubercles : the pubescence is very scant ; the antennae have the same 



//. crista ; and there can be 



diffe 



the elytral crests.

 Although resembling the Australian Disternce in general appearance, this 

 genus differs much from them in structural characters and approaches much 



Hybolasi 



and has a far larger 



nearly the same. The thorax, however, is much shorter, 



and more acute median spine. The apical ventral segment is much elongated 



and broadish at the apex in my single specimen : but I suspect this is a
