fainti}' indicated in the metazona only. Wings coloured 

 basally and strongly infumate in the rest. Prosternal 

 tubercle thick, obtuse Pachyphymus, gen. nov. 



The genus AcorypheUa, Giglio-Tos (with two species in 

 it, A. zonata G.-T. and A. punctata G.-T.) is not included 

 in the key, as it has been described by the female sex 

 only, and its exact relationship is impossible to determine 

 without studying the types. 



Genus Brachyxenia Kirby. 



1914. Brachyxenia Kirby, Fauna Brit. India, Acrid., 

 pp. IPS, 256. 



This curious genus reminds us in its habitus of an Eremo- 

 biin rather than of a member of CaUiptamini; but the 

 structure of the prosternum and especially that of the 

 male cerci, which are of the same type as in Caloptenopsis, 

 leaves no doubt as to its proper systematic position.

Genus Sphodromerus Still. 



This genus is as yet very badly known, and a revision 

 of its species appears not to be possible until more material 

 Avere studied. The majority of the known species are 

 described by their coloration only, and one may presume 

 that the coloration in this genus is as inconstant as it is 

 in Calliptamus. The genus is confined to the Eremian 

 subregion of the Palaearctic region, and the number of 

 undescribed species is, probably, not a small one.
