some neio Species of Sagra, Sfc. 255 



deeply emarginate lower edge of the face ; the extent of surface 

 visible varies greatly in different individuals, rendering it more 

 than probable that the insect in life has the power of retracting to 

 a certain degree the part within the head. The anterior edge is 

 bordered by a broad membranous margin. Cheiloxena has very 

 strong affinities with the Longicornia ; in fact, in many genera 

 amongst the Lamicidcc (the family to which it is most nearly 

 related) a similar Structure of the epistoma exists. It is, however, 

 at once separated from that group, as well as from the majority 

 of the tribe, by its simple eyes ; whilst the perpendicular head 

 and the absence of a neck forbid its being placed with the Leptu- 

 ridce, the only longicorn family possessing a similar form of eye. 

 I have not therefore hesitated in uniting it with the Phytophaga, 

 of which great tribe it will probably ultimately form a distinct 

 family ; for the present I have placed the genus with the Sagridce, 

 with which family it appears to have most characters in common. 

 It agrees with it in having a narrow tliorax and a distinct pro- 

 sternum, differing in the free epistoma, non-incrassate and un- 

 armed hinder thighs, and {Amalella excepted) in the toothed claws. 

 From the Donacidcs and Crioceridce it is separated by the distinct 

 prosternum ; from the Chnjsomelidce by the narrow thorax and 

 smaller third joint of the tarsi ; and from the Eiimolpidce by this 

 latter character and the different form of the antero-lateral plate of 

 the antipectus ; it also differs from all the previously mentioned 

 groups, approaching the Cli/thridce and allied families, in the 

 contraction of the intermediate abdominal segments. 



Cheiloxena Westyvoodii, n. sp. (PI. XIV. figs. 1, 2.) 



Sub-elongata, convexa, opaca, fusca, pilis squamaeformibus 

 adpressis obscure fiavis (his hie illic in elytris in maculas 

 parvas condensatis), induta, capite thoraceque fortiter et 

 crebre punctalis, hoc sub-cylindrico, lateribus ante medium 

 dentato ; elytris fortiter sub-crebre striato-punctatis, utrisque 

 sereibus quatuor tuberculorum elevatorum instructis. 



Long, 4 — 5-1 lin. 



Sub-elongate, convex, opaque, obscure fuscous, whole body 

 covered with short adpressed scale-like hairs, which are con- 

 gregated here and on the surface of the elytra into small obscure 

 fulvous patches. Head coarsely and closely punctured ; face 

 vertical, somewhat wedge-shaped, its inferior margin deeply 

 notched ; eyes prominent, rotundate-ovate, their inner edge 

 feebly sinuate ; antennae robust, nearly three-fourths the length
