Two males and three females. A species easily recogniz- 

 able by the structure of tlie autennse, head, and prothorax 

 in the cJ . The sides o£ the prothorax are dentate in this 

 sex, as in H. dentatithurax^ Pic. The '^ may be known 

 from that of //. amoenus, as here restricted, by the wholly 

 black outer joints of the antennse and the black posterior 

 knees. The long parallel-sided fifth antennal joint of the 

 cJ is a striking character. The uigro-niaeulate pygidium 

 of the ? is common to many Hedybii with testaceous 

 abdomen. Figs. 15, 15 a (PI. XIII.) show the head from 

 in front and behind.

(^ . Antennre (PI. XIII. fig. 16 a) nearly as long as the 

 body, rather slender, testaceous, joints 3 and 4< together 

 about as long as 5, each with a polished, concave, black 

 area beneath ; head (PI. XIII. fig. 16) broad, testaceous, 

 black at the base (a spot in the middle of the vertex 

 excepted), the inter-ocular excavation black along the centre, 

 jjubescent, extremely deep, with a recurved, dentiform plica 

 in the middle in front and a smooth fovea bebind it, the 

 jnxta-ocular elevations stout, angular, concave within (the 

 excavation as seen from the anterior aspect limited in front 

 by a curved ridge, which extends backward over and around 

 the lateral prominences, enclosing an oval concave space) ; 

 prothorax transversely subquadrate, dentate at the sides 

 behind the middle, and with the lateral margins obliquely 

 refiexed and ciliate anteriorly, the dorsal black patch trans- 

 verse, dentate in the centre behind, the rest of the surface 

 testaceous, the margins sometimes with a small black spot ; 

 elytra blue or green, densely, rugulosely punctured ; abdo- 

 men, coxse, and legs testaceous, the metasternum green ; 

 anterior tarsal joint 2 produced over the base of 3, black at 

 the tip.
