543 Mr. B. P. Uvarov on 



rcijular false vein. Hind femora moderately dilated, with 

 the apex sli<jhtly attenuate. Hind til)i:e a little sh()rter tluni 

 t'caiora ; inner lower spur more than twice as loni^ as the 

 lower outer one and about one-third lon^jer than the inner 

 upper spur ; both inner spurs thick, gradually bent. The 

 external p^enitalia as in ^-Eolopus. 



Genotype: Gnmphocerua {Kpacroni'ia) socius, Stal. 



This new ojenus is very easily separated from the closely 

 related ^olopna, as well as from otber genera of the same 

 group, by the almost vertical position of the temporal 

 foveolre, which are, besides, not raarginated behind; the 

 length of the inner tibial spurs is also very characteristic.

The species is extremely variable not only in its coloration, 

 bnt in some morphological characters as vrell. Thus, the 

 hind angle of the pronotnm may be either sharp or straight ; 

 the lateral keels are s )metimes rather well developed even 

 in the metazona, and sometimes scarcely perceptible in the 

 prozona ; there are often two irregular longitudinal keels 

 parallel to the median keel (mentioned by Stal, /. c. p. 343),

AneBolupus socius (Stt^l). 



bnt in many cases tliere is no trace of those keels ; elytra are 

 now shorter than hind femora, now distinctly longer and 

 more narrow. As for coloration, St. prasinns, AValk., and 

 Ep. minuscula, Walk., represent two extreme forms, which 

 are connected by an uninterrupted series of intermediate 

 colour-forms, and Gomphocerus socius, St., belongs to one
