EOTHES gen. nov. (r/d>9i). 



A genus iif Acanthaspidina of unusually slender form. Head onlv a 

 little longer than broad, the eyes of moderate size and prominent, the part in 

 front of them ahont t\vice as long as the postocular part, the front truncate 

 and slightly cmarginate ; ocelli large, situated opposite the hinder edge of 

 the eves, separated only by their own diameter or slightly more than that. 

 Antenna' apparently seated on small prominences somewhat in advance ( ,f 

 the eves, the prominences with a small exterior spine; first joint lon^> -i. 

 longer than the width of the thorax, second and third joints subequal, and 

 a little slenderer and shorter than the scarcely incrassated terminal joint, 

 the whole nearly two-thirds as long as the body. Thorax as a whole 

 cuneiform, tapering forward regularly but not strongly, the sides ah 

 straight, the tapering portion scarcely shorter than its breadth, unarmed ; 

 -ciiielluni \-en tapering, pointed, but h.mlh produced into a spine I egs 

 long and slender, wholly unarmed, similar in form to those of (>p-ico tus, 

 the first hind tarsal joint nearly twice as long as the second and third 

 together. Hemelytra slender, with no prominent veins, the corium elon- 

 gated externally, the membranal suture \<T\ oblique and sinuous. 



Apparently nearest to Opsicoetus Kin-, this genus diller> from it in its 

 much slenderer form, the. want of a strongly constricted neck, and the 

 sloiitne.-s of the terminal joints of the antenna' : the structure of the tarsi is 

 also peculiar. 



A single species is known.
