This species is very widely distributed. I have it from Turkestan 

 as a parasite of Scolytus rugulosus. A. A. О g 1 о b 1 i n reared it at 

 Poltava from Hylesinns fraxini and W. P. P о s p e 1 о v , at Kiev, from 

 an unknown bark-beetle. 



Species described under generic name Pteromalus, 

 but having the abdomen petiolate. 

 cecidomyiae Ratz., I, p. 192. 



Note. Posterior tibiae with two spurs, one of nor- 

 mal size and another very minute. I believe it is better to 

 consider this species as belonging to Miscogasterinae. Abdomen 

 with petiole, which is very short. Propodeum convex, neck very 

 small, spiracles round. Abdomen shorter than the thorax, wings 

 large, eyes nacked. Males have normal palpi. Tribe Halticopte- 

 rini, near to the genus Dicycliis Walker. 

 eremita Förster, 1841, p. 29, n. 253. 



Note. Very similar to Coelopisthia, but the abdomen not 

 sessile and occiput immargined. Dr. G. May r proposed to describe 

 a new genus upon an undescribed species, to which genus this 

 species must be placed also. 

 halidayanus Ratz., II, p. 207. 



Note. Has two spurs on the hind tibiae and therefore 

 must be placed to Dicyclus Walker. Resembling in its generic 

 characters cecidornyae Ratz. Second spur of the hind libia 

 larger. 

 monochrous Förster, 1841, p. 14, n. 40. 



Note. Belongs to Sphegigasterini. 

 pini Ratz., I, p. 193. 



Note. Congeneric with halidayanus Ratz. 

 singularis Förster, 1841, p. 27, n. 227. 



Note. Belongs to Sphegigasterini. 



Gen. Pachyneuron Walker. 



(All species listed below have antennae with two ring joints.) 

 amoenus Förster, 1841, p. 28, n. 238. 

 coccorum R a t z., II, p. 197, n. 37. 



Note. Marginal vein not very thick, its width is equal on 

 the whole lenghth. Parapsidal furrows deep enough, but not 

 reaching scutellum.
