362 TERTIARY INSECTS OF NORTH AMERICA. 



them. If we were to base our judgment on the comparisons with the mod- 

 ern species which Gravenhorst and Germar in nearly every case instituted, 

 we should reach the conclusion that the Capsina alone had been found, and 

 that no less than half the divisions which Renter founded in this subfamily 

 were present and a large number of genera. Thus of the Plagiognatharia 

 we have Harpocera ; of the Oncotylaria, Hoploniachus (two species) and 

 Oncotylus; of the (Jyllocoraria, JEtorhinus and Systellonotus ; of the Cap- 

 saria, Capsus, Orthops, and Lygus ; of the Phytocoraria, Homodemus, 

 Dichrooscytus, and Phytocoris ; and of the Loparia, Lopus ; in all a dozen 

 genera, and there is at least one other among those species figured by Ger- 

 mar which were unaccompanied by comparisons with modern types. 



In America we have four of these divisions represented, viz : Cylloco- 

 raria by Closterocoris ; Capsaria by Capsus (two species) and Poecilocap- 

 sns (five species); Phytocoraria by Aporema; and Loparia by Hadronema; 

 while Bryocoraria, not recognized in amber, is represented by two species 

 of Carmelus and one of Fuscus. All of these come from Florissant. 



It thus appears that we may recognize among the fossils every one of 

 the divisions instituted in the family by Renter that have any considerable 

 present development of species, excepting only the Miraria, and to cover the 

 possibilities of this also there are two species of Miris not referred to mod- 

 ern genera, one mentioned by Gravenhorst from amber and one bv Curtis 

 at Aix. It may also be noticed that the assemblage of fossil forms shows 

 as a whole a leaning toward American types, more noticeable, however, 

 among the American than the European forms, the more striking being in 

 the development of the Loparia and Bryocoraria. Not too much stress, 

 however, should here be placed upon these considerations, as a reexamina- 

 tion of the amber types is necessary before certain conclusions can be 

 drawn, and the affinities of several of the Florissant forms is vague at the 

 best. 



CLOSTEROCORIS Uhler. 



A single species exists in a living state in our western Territories, with 

 which a single striking and not uncommon Florissant species agrees well 

 in structure but from which it differs considerably in markings. The ter- 

 minal joints of the fossil species appear to be relatively longer and the sec- 

 ond joint relatively shorter than in the existing type.
