HBMIPTEKA— HETEROPTERA-CAPSID.E. 361 



LYCTOCORIS Hahn. 



This genus, found in tlie north temperate regions of both the Old and 

 New Worlds, but more abundant in the latter, has not before been found 

 fossil. The single species from the Green River beds which we place here 

 was formerly referred, doubtfully, to Rhyparochromus.

A single poor specimen apparently belongs to this subfamily, but is 

 too imperfect to locate witli any precision. The body is of nearly equal 

 width, but with a full abdomen. The head is broken, but is as broad at base 

 as the tip of the thorax, has a rounded-angular front, and its surface most 

 minutel}^ punctulate. The thorax was broadest behind, the sides tapering 

 slightly, and gently convex, the front border broadly and shallowly con- 

 cave, the hind border straight, more tlian twice as broad as the median 

 length, the surface, like that of the head, with faint distant punctures. 

 Scutellum rather small, triangular, pointed, of equal length and breadth, 

 about as long as the thorax, its surface like that of the thorax, but with more 

 distinct punctures. Abdomen full, well rounded, and very regular. Teg- 

 mina obscure (but perhaps extending only a little beyond the scutellum).

With the exception of a Miris, reported over half a century ago from 

 Aix and never yet described, all the European fossils of this group known 

 up to the present time are from amber. Thus Gravenhorst long- ago referred 

 half a dozen species from amber to Miris and Capsus, and Germar later 

 described as many as thirteen species of Phytocoris from the same deposits. 

 These genera were then used in a far broader sense than now, and the 

 figures of Germar show at once that several genera are to be found among
