rising from a frontal prominence; basal joint or joints rather 

 long; 3i'd joint as long as 1st and 2nd together, with a con- 

 spicuously white terminal style. Thorax normally shaped, with 

 dense though not very conspi(;uous pubescence without any bristly 

 hairji. .Scurelhim large, resembling thorax in colour and pubes- 

 cence, with a fairly conspicuous marginal fringe. Abdomen 

 elliptic, as long as thorax and scutellum together; basal segment 

 short, the others normal. Pubescence fairly abundant and equally 

 distributed, always tawny except at tip. Legs rather strong, quite 

 simple unless the tarsi are rather widened. Wings with the 

 venation found in Sijiyhus; anterior cross-vein rather before 

 middle of discal cell, rather upright; veins closing 1st and 2nd 

 posterior cells rather angulated at the flexure. 



The above description is abbreviated from that of Verrall *. 

 This genus falls in the OHRTSOTOXiNiE, and differs from Chryso- 

 tOLVumhY the antenna? being stylate, as compared with the dorsal 

 position of tlie arista in the latter genus. 



Range. Europe, Mediterranean, Orient, IS". America, Mexico. 



Life-histori/ apparently unknown. Females of C. yerburyi, 

 Verrall, have been noticed in Scotland paying fleeting visits to 

 pine-stumps. 



Only two species have been recorded from British India. 

 Both were described in a paper by the late G. H. Verrall which 

 appeared posthumously (Trans. Eiit. Soc. London, 1913, pp. 323- 

 333). The descriptions are reprinted here without alteration.
