KHYNCHOPHOKA.

Seven specimens, showing no sign of variation. The system of coloration of this 

 insect is very like that of certain species of the genus Ambates.

10. Phyllerythrurus xanthozona, sp. n. (Tab. IV. figg. 30, 30 a, s .) 



$ . Fusiform, opaque above, black, the elytra each with a rather broad, oblique, outwardly- widened, ochreous 

 fascia just before the middle. Head closely punctate ; rostrum very stout, curved, much shorter than 

 the prothorax, the abruptly-widened basal portion closely punctate and profoundly sulcate, the outer 

 portion much smoother. Prothorax as long as broad, subcorneal, somewhat dilated at a little before the 

 middle (the sides appearing sinuate behind), bisinuate at the base, very sparsely and somewhat coarsely 

 punctate, the disc broadly excavate posteriorly. Scutellum large, flat, triangular. Elytra moderately 

 long, rounded- subtriangular, finely punctate-striate, the interstices obsoletely uniseriate-punctate. Pygi- 

 dium coarsely punctate, subcarinate at the tip. Beneath sparsely punctate ; ventral excavation broad and 

 very deep, extending forwards along the metasternum for about two- thirds of its length. 









Length lOf , breadth 4^ millim.

One male. In this species the rostrum is comparatively short, profoundly sulcate at 





■ 



the base above ; the prothorax is subcorneal, deeply excavate on the disc ; and the 



■ 



ochreous fascia on each elytron is oblique and widened outwards.

EUCACTOPHAGUS, gen. nov. 





Peduncle of the submentum narrow, not sulcate or vertically bilamellate in front ; metasternum conically 

 protuberant or tumid between the more or less widely separated intermediate coxae; anterior coxce 

 narrowly separated ; the other characters as in Phyllerythrurus. 



Type, Calandra aurofasciata, Breme. 







The protuberant antero-intercoxal process of the metasternum 



character not 



by Chevrolat in his description of E. orizabensis) is the chief peculiarity of th 



■ 



typical members of the present gen 



In E. aurocinctus this feature is reduced 



minimum, but as that species is undoubtedly nearly allied to E. graphipt 

 placed here. Two groups of species are 



indicated — one with reddish or ochreous 











markings on the elytra, the other with a large velvety-black patch on each 

 The pygidium is more or less raised or subcarinate down the middle.
