structure. Indeed in its thickened head, abbreviated, 

 subtriangular rostrum, and depressed eyes, no less than in 

 its greatly shortened antennas and its long and slender feet, 

 the genus has very much the sub-Hylastideous aspect of 

 Stenoscelis : and it may be defined therefore to differ 

 essentially from Rhyncolus in its much shorter and more 

 triangular rostrum ; in its larger and more sunken eyes, 

 which are appreciably less lateral (or more sub-approxi- 

 mated above) ; in its prothorax being altogether more 

 cylindrical and developed ; in its very much more abbre- 

 viated antennas (the scape of which is so reduced in length 

 as to be even shorter than that of Stenoscelis, indeed as 

 short as in the European genera Stereocorynes and Hexar- 

 thrum, or as in Calyciforus and Eurycorynes from Brazil), 

 the club of which, although compressed, is exceedingly 

 rounded, solid, and abrupt ; in its first and second abdo- 

 minal segments being much more conspicuously divided 

 from each other; in its legs and tarsi being slenderer 

 (with the tibial hook more straightened, and the basal 

 joint of the latter rather more elongate) ; and in its coxas 

 being more approximated, the four hinder ones, in fact, 

 being nearly contiguous. In its scutellum however being 

 conspicuous, Brachytemnus recedes from Stenoscelis, and 

 agrees better with the other immediately-allied forms. 



120. CALYCIFORUS (nov.gen.). The very extraordinary 

 insects, which have been communicated by Mr. Fry and 

 Mr. Janson, for which the present genus is established, 

 and which were captured in the provinces of Rio Janeiro 

 and Bahia in Brazil, are amongst the most remarkable 

 members of the Cossonidce with which I am acquainted ; 

 and yet their affinities are, unquestionably, with such forms 

 as the European Brachytemnus, Eurycorynes from Brazil, 

 and Stenoscelis from S e . Helena, Southern Africa, and 

 Japan. Indeed in its thickened head, short, subtriangular 

 rostrum, and sunken, subapproximated eyes, as well as in 

 its excessively abbreviated antennas, its slender, filiform 

 feet, and the fact of its four anterior coxas being nearly 

 contiguous, the genus has much marvellously in common 

 with the first of those groups ; nevertheless the compara- 

 tively large size of its members, and the deep and anoma- 

 lous triangular excavation in the middle of their prothorax 

 behind (immediately in front of the greatly developed 

 scutellum), added to the extraordinary sculpture of their 

 elytra (the sulci of which are wide, deep, opake, and
