close association with Certichtis, and the new form must, I think, stand as 

 the representative of at least a new sub-tribe, which may for the present 

 be placed between the Ceruchini and Sinodendrini. 



With the exception above noted, the following generic diagnosis is 

 believed to be sufficiently full for comparative purposes : 



Phyllostoma, gen. nov. 

 Mentum longer than wide, narrowly rounded in front, mental suture 

 scarcely traceable. Palpi moderate in length, their supports visible ; third 

 joint of maxillary slightly transverse, fourth fusiform and as long as the 

 second and third combined ; joints of labial palpi increasing in length. 

 Mandibles small, with a conspicuous externally bidentate process. Head 

 small, less than half the width, and with the mandibles but little more 

 than half the length of the prothorax. Labrum connate with the 

 epistoma, the suture very fine. Eyes very prominent, subglobular, not 

 emarginate. Antennae straight, first joint stout, elongate oval, second 

 similar but smaller, forming with the first joint about one-third the length 

 of the organ ; joints 3-7 small, becoming transverse ; club three-jointed, 

 subequal in length to joints 3-7. Prothorax transverse, widest a little 

 behind the middle, sides strongly rounded. Elytra a little wider than the 

 prothorax and about twice as long, sides parallel. Front coxae transverse, 

 subcorneal and strongly prominent ; middle coxae transverse, much less 

 prominent; hind coxae flat. Legs long; hind femora very stout; front 

 tibiae strongly bidentate externally, with three or four small denticles 

 above the upper tooth ; middle and hind tibia; not dentate, but with 

 a transverse ridge fringed with spinules on the outer and posterior side, 

 the apex also fringed with short, close-set spinules ; tibial spurs as usual 

 in the family; tarsi unusually long. Abdomen with six distinct 

 segments. 



P. fimbriata, sp. nov. 



Elongate, cylindrical, brown, side margins of thorax and elytra 

 fimbriate with long hairs, under surface and legs sparsely hairy. Head 

 coarsely, rather closely, punctate ; clypeus refiexed, quadridentate ; front 

 concave at middle, the concavity limited by ridges which converge 

 backward ; inner margin of the eyes elevated, especially posteriorly, and 

 forming minute, but prominent, tempora. Prothorax convex, finely 

 margined, a little wider than long, widest two-fifths from the base, sides 

 strongly rounded, front angles obtuse but defined, hind angles wanting, 

 the sides rounding into the base ; surface rather finely and sparsely
