IIEMIPTERA— HETEROPTERA— KEUUV^IID.E. 355 



Subfamily ACANTHASPIDINA Stal. 



The only species liitlierto found fossil in this subfamily group is one 

 desci'ibed many years ago as a Platymeris by Germar, and was found in 

 Prussian amber. The one given below is the first from the rocks. 



EOTHES gen. nov. {7J(i9i). 



A genus of Acanthaspidina of unusually slender form. Head only a 

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

 front of them about twice as long as the postocular part, the front truncate 

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

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

 Antenna? apparently seated on small prominences somewhat in advance of 

 the eyes, the prominences with a small exterior spine ; first joint longest, 

 longer than the width of the thorax, second and thii-d 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 almost 

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

 scutellum very tapering, pointed, but hardly produced into a spine. Legs 

 long and slender, wholly unarmed, similar in form to tliose of Opsicoetus, 

 the first hind tarsal joinr, nearly twice as long as the second and third 

 together. Hemelytra slender, with no pi'ominent veins, the corium elon- 

 gated externally, the membranal suture very oblique and sinuous. 



Apparently nearest to Opsicoetus King, this genus difi'ers from it in its 

 nuich slenderer form, the want of a strongly constricted neck, and the 

 stoutness of the terminal joints of the antennae ; the structure of the tarsi is 

 also peculiar. 



A single species is known.

The whole body is dark, but is marked laterally by a black stripe 

 which follows the outer margin of the thorax viewed from above, from the 

 base of the hemelytra forward, and appears to cross also the head, follow- 

 ing the inner margin of the eye and terminating on the front, the whole 

 tolerably straight and continuous, with a slight angle in passing from the
