134 MACROPHYA RUSTIOA. 



From the allied species, Ribis is distinguished by the 

 blackish clypeus (in the ? ) and pronotum, immaculate 

 and strongly punctured scutellum, the abdomen with- 

 out white markings, and its generally dull and less 

 shining colour. The amount of white on legs and 

 mouth parts varies. 



Personally I know nothing about the history of 

 this species, and what has been written about it is 

 rather conflicting. Schranck describes the larva as 

 green with a rugose body with two minute black dots 

 on the vertex, and feeding on Ribis. Dours (Cat. 

 Syn., p. 22) states that the larva lives on the goose- 

 berry, and has for parasites Pygostolus sticticus, Hal., 

 and Mesoleius armillatorius, Grr.=luteifrous, Gr. (ac- 

 cording to Goureau). Kaltenbach, on the other hand, 

 says that it is suspected to have a similar history to 

 albicincta. The larva he describes as very like the 

 latter, the head orange-yellow with a black mark on 

 vertex and anus, and without any lateral markings. 



In Britain ribis is confined to the South of England. 

 Stephens says it occurs in DarenthWood. It is taken 

 at Glanvilles' Wootton by Mr. Dale, and at Norwich by 

 Mr. Bridgmau. 



It is met with in Sweden, Holland, Germany (in 

 gardens according to Hartig), Prussia, France, Italy, 

 Switzerland. 



Lanceolate cellule shortly contracted ; transverse median nervure 

 received close to basal. Legs yellowish-white, posterior 

 femora, tibiae and tarsi marked with black; abdomen with 

 white markings at base, sides, and apex; thorax strongly 

 punctured; wings hyaline, darkened at apex, stigma black 

 (Species 7).
