Of these ten genera a total of* thirty-six species has been examined. 



Several genera like Chloealtis and Toxopterus are rather aberrant 

 and really occupy isolated positions, that of Chloealtis, however, being 

 somewhat modified by Cocytotettix, which is in a way a transition 

 type. The European Calephorus is also somewhat removed from the 

 nearest ally Parorphula, but its position appears to be in this group 

 and its affinity is clearly with the above-mentioned genus. The rela- 

 tionship of Sisantum and Orphulina is close, as an examination of the 

 type species of each shows, but, for the present at least, I have con- 

 sidered them distinct. The only American genus not examined is 

 (Eonomus Scudder, from California. 



CALEPHORUS Fieber. 



1853. Calephorus Fieber, Lotos, III, p. 97. May, 1853. Included C. 

 elegans Fieber and Gryllus dubius Rambur, both equalling Acrydium com- 

 pressicornis LatreiUe. 



1854. Oxycoryphus Fischer, Orthoptera Europisea, p. 311. Type, Acry- 

 dium compressicornis Latreille. 



This genus is mentioned merely to show its relationship to Paror- 

 phula from which it appears to be an offshoot. Aside from the pres- 

 ence of a distinct intercalary vein no character of great weight is ap- 

 parent to distinguish Calephorus from Parorphula. Three females of 

 C. compressicornis from France and Egypt have been examined. 



PARORPHULA Bruner. 

 1900. Parorphula Bruner, Ace. Gen. Spec. Locusts Argent., pp. 22, 25. 

 Included P. graminea, pallidinota and strigata Bruner, of which the 

 first, graminea, can be selected as the type. 



This genus appears to form a transition type between Calephorus and 

 the Sisantum-Orphulina group.
