sometimes foveate or hollowed down the middle. Elytra a little wider than the prothorax, crenate-striate,

Eight males and three females, six of them with the markings precisely similar. The

rather coarse, dense puncturing of the upper and under surfaces, the inferiorly serrate 

 and apically annulate rostrum of the male, the almost straight base of the prothorax,

 Phyllerythrurus callizona, Chevr. op. cit. 1885, pp. 92, 93 2 . 



Oblong-elliptic, opaque above, black, the elytra with a transverse fulvous fascia (of variable width, not 

 reaching the suture or outer margin, and narrowing outwards) below the base. Eostrum stout, 

 arcuate, nearly as long as the prothorax, very sparsely, finely punctate, smooth at the tip, feebly 



of the 9 a little smoother and not so stout, the frontal fovea deep. Prothorax as long as broad,

gradually and arcuately narrowing from about the middle, bisinuate at the base ; closely, finely punctate

hollowed down the middle anteriorly. Elytra much wider than the prothorax, oblong-subcordate, 

 somewhat coarsely and deeply punctate-striate, the interstices feebly convex. Pygidium sparsely, 

 coarsely punctate. Beneath closely and rather coarsely punctate, much smoother down the middle, the 

 ventral excavation of the $ very deep and extending forwards along the apical half of the metasternum. 

 Tibiae closely ciliate, the hairs moderately long on the posterior pair in the c? , short in the $ .

This species resembles Eucadophagus orizabensis in colour, but it is narrower

and more oblong, the metasternum is not protuberant, &c. The insect is scarcely 

 recognizable from the inaccurate dii

16. Metamasius ochreofasciatus, sp. n. (Tab. V. figg. 23, 23 a, $ . 



Elongate-oval, robust, opaque above, black, the elytra each with a narrow, undulate, transverse, ochreous 

 fascia just beyond the middle (not reaching the suture or outer margin). Rostrum stout, cylindrical, 

 curved, about two-thirds the length of the prothorax, obsoletely punctate, the frontal fovea rather deep.

* The rostrum is said to be " basi crasso, profunda scisso," which must have been an error of observation.
