204 LLOYDS NATURAL HISTORY. 



iv. Melanitis group. None of the nervures inflated at the 

 base ; claws bifid. Lower disco-cellular nervule as long, or 

 longer, than the middle one, and connected with the median 

 nervule at a right angle. 



Genera: MELANITIS, GNOPHODES, TISIPHONE, AND C/EROIS 

 (aberrant). 



v. Satyrus group. Costal nervure generally, and the median 

 and sub-median nervures less frequently inflated at the base, 

 but sometimes only thickened. Claws simple. Lower disco- 

 cellular nervule of the hind-wings longer, or at least as long as 

 the middle one, and connected with the median nervule at an 

 acute angle. 



(This group may be divided by superficial characters into 

 four sections, represented by Euptychia^ Ypthima> Erebia^ and 

 Satyrus [ = Hipparchia\). 



vi. Pronophila group. Costal nervure always inflated ; 

 median nervure generally thickened, but not inflated. Middle 

 disco-cellular nervule of the hind-wings always longer than the 

 lower one, waved or angulated, with or without a spur in the 

 discoidal cell. Lower disco-cellular nervule small, straight or 

 curved outwards, and united to the median nervure at a right 

 or at an obtuse angle. 



Genera: CALISTO, ELINA, LYMANOPODA, OXEOSCHISTUS, 



PRONOPHILA, LASIOPHILA, D^DALMA, CORADES. 



It will be most convenient to follow this arrangement, in the 

 main, mentioning the British species and the most important 

 foreign genera, besides those figured under each group. The 

 Elymniin(z, which Schatz and Rober regard as aberrant 

 Satyrinct, will be treated as a distinct Sub-family.
