150 CORYPHOCERA ROUYERI. 



Coryphocera rouyeri^ n. sp. 



Light golden green, shining; a minute spot at the base 

 of the head, a large roundish discoidal spot on the thorax, 

 with a smaller round black spot in its centre, and two 

 transverse bands on the elytra of a chestnut colour, the 

 first of these bands occupies the basal two-fifths of the 

 elytra but does not quite reach the outer margin, the 

 second is narrower, commencing at about three-fifths from 

 the base and extending obliquely to the apical callus and 

 also continued along the suture to the apex; the extreme 

 outer margin of the elytra, the base of the pygidium, 

 hind coxae, margins of the abdominal segments, antennae, 

 palpi and the greater part of the tibiae also of a brownish 

 red, or chestnut colour ; margins of the cephalic horns 

 and the tarsi pitchy black. Length 18 — 20 mm. 



Head coarsely punctured at the sides, more sparingly 

 so in the centre, a short deflexed horn, or plate, at the 

 base, having a deep rounded central notch and forming 

 a short, somewhat obtuse, point on each side of it, the 

 apex of which extends as far forward as the level of the 

 front margin of the eyes, beyond and beneath this is 

 strongly concave ; side margins of the clypeus produced 

 into two, slightly convergent, stout horns which are con- 

 cave on the inner side, obtuse at the apex, strigose, and 

 about equal in length to the fore part of the head from 

 the base of the frontal notch, the front margin of the 

 clypeus projects a little beyond the base of the horns, is 

 slightly sinuous and a little impressed in the centre. Tho- 

 rax sparsely punctured at the sides, basal margin tri- 

 sinuate. Scutellum with a few punctures at the base. 

 Elytra slightly narrowed behind, punctate-striate, the punc- 

 tures fine on the disc, coarse and assuming a semi-circular 

 form towards the sides behind, a cluster of fine punctures 

 on each side of the scutellum at the base ; the sutural apical 

 angles produced and acute, 



Pygidium and underside with sparse strigiform punc-
