18 represented liv a species at Oenin^en and another at Aix, and iSrachv- 

 pelta one at Kmttensee. Neither ot' these extinct generic types occurs in 

 our Tertiaries, where this subfamilyis far more prolific than in Kumpe and 

 far surpasses the Pentatomida. With the exception of a couple of forms, 



represented each l>v a single specimen, and which are referred to modern 

 types, ( 'vrtomenus and Discostoma, all the others are remarkable for differ- 

 ing apparently from nearly all living types and a!>o from the known to iU 

 in the short and accurately triangular sciitellum, agreeing in this iv^pe.-t with 

 the Florissant Pentatomida, and, as there, necessitating the establishment of 

 several new generic groups. These, howeyer, are more prolitic in species, 

 and the species in individuals, than is the case with the Pentatomida.
