112 OYNIPS KOLLARI. 



species are known, almost entirely from the middle 

 and south. The genus is unknown in Scandinavia, 

 and it is a moot point if our own species (Kollari) is 

 really native.

Reddish-yellow ; the scutellar fovea3, the median segment, and more 

 or less of the abdomen above black ; the legs paler than the body ; the 

 fore-tibise with short depressed hairs ; the antennae 13-jointed ; the 

 basal joint paler than the others ; wings hyaline, with a reddish 

 tinge. ? . 



Length 4 — 5 mm. 



According to Mayr, Cynips corruptrix, Schl., G. 

 aries, G-ir., 0. lignicola, Htg., G. tinctoria, G. calici- 

 formis, and G. galeata, Grir., cannot be distinguished 

 from Kollari in the imago state, but the galls are very 

 different with all of them. This gall-fly was long 

 known as the Devonshire gall, apparently from its 

 having been first noticed in Devonshire. It was first 

 brought before the entomologists of this country in 

 1854 by Mr. Rich, who reported it as being very 

 abundant in Somersetshire and Gloucester (' Proc. 

 Ent. Soc.,' 2nd series, vol. iii, p. 35). Mr. Stainton 

 stated (1. c.) that he had noticed the galls in Devon- 

 shire for the last four or five years ; Mr. Parfitt that 

 he had seen them about 1848 ; and lastly, Mr. Jordan 

 (1. c, p. 40) remarked that he had observed them 

 twenty years before, which would bring the earliest 

 notice of the galls in this country to, say, 1834.
