Genus Calliptamus Serv. 



There are seven species of this genus in Kirby's Cata- 

 logue (iii, p. 549-551), but three of them (C. marnwratus 

 F.-W., C. cephahtes F.-W. and C. discoidalis Walk.) are 

 conspecific with C. italicus L. ; C. tarsius F.-W. is a syno- 

 nym of Euprepocnemis plorans Charp. ; and C. scuHfer 

 Walk, has been made by Kirby the type of a distinct 

 genus, Brachyxenia. Thus, only two species remain in 

 the genus Calliptamus : the common South-Palaearctic 

 C. italicus L., and the Canarian C. vidcanius Krauss., 

 because the two African species described more recently 

 (C. v-plagiatus Brun. and C. meruensis Sjost.) belong to 

 the genus Caloptenopsis, and C. abbreviatus Ikonn. from 

 Corea is scarcely specifically distinct from C. italicus, 

 representing the form of the latter species known as var. 

 icterica Serv. ( = wattenwyliana Pant. ; see H. Karny in 

 Wiss. Erg. Exped. Filchner nach China u. Tibet, x, 1, 

 p. 35, 1908).
