SUMMAllY OF GALL-1'RODUCERS SINCE 187-2. '29 



Nematus baccartwi, Cameron (E. M. M. xii. 189).— "From 

 berrv-shaped gall of a grayish green colour, covered closely 

 with fine white hairs, on the leaf of a willow — near S. 

 aurilay {I. c). 



N. crassipes, Thorns., var. J'acciniellus, Cameron (E. M. M. 

 xii. 190). — "Bred from galls on Vacciniiim Viiis-Ic/tea'' (I.e.). 



N.v/miii<ilis,h. (=ijiiercu><, Fz. = gdllorum, DeGeer, H.). 

 — I have bred Semali which 1 believe are referable to the 

 above species from the round, smooth, rosy galls which are 

 found on the midrib of the bitter [Salir inoiiandra), and 

 probably other closely-allied willows, kindly sent n)e in some 

 numbers from Yorkshire by Mr. Inchbald, who writes n)e — 

 "The gall of the bitter willow, Cameron writes me word, is 

 produced by Nematus cinerece, of Relz — a common enough 

 species." There is surely some confusion here; see above for 

 Cameron's description of ihal gall. Viniliui/i.t galls are first 

 noticeable in June; the larva is full fed and leaves ihe gall in 

 August, and I have bred the sawflies in the first fortnight of 

 June (Life-history, see 'Zoologist,' 1863, p. 8473). 



A^. Vol/enlioieni, Cameron (Scot. Nat. ii. 296, Life-history 

 and description). — From galls resembling those of the Ibrmer 

 species on Sa/ix purpurea. 



N. crassulus, Dahlb. — " Not uncommon on the banks of the 

 burn at Camachgouran : according to Thomson N. crassulus 

 is a gall-maker." P. Cameron (Scot. Nat. ii. 358).* 



Chalcidid^. 



Eurijloma Iiyalipemns, Wlk. (== afra, Boh. = ? grmnini- 

 cold, Gw.) (Enlom. v. 239, 264).— This Chalcid is the 

 producer of galls on Amnidpliila areixiria and Trilicum 

 repens ; at least I have failed to ditfeienliale the species bred 

 from ihe galls on the sea reed, sent me in nunibers by AJr. 

 Inchbald, and those from the twitch, which 1 find couiujonly 

 in Essex. The galls, which are generally distributed (Scot. 

 Nat. i. 195), consist of iml)ricated buds on the principal 

 stalk, and are easily seen and collected in their dry state in 

 the winter: I have bred the flies in June and Jidy. 



E. de})ress(t, Wlk. (Enlom. v. 239, 451). — From galls on 

 the stems of Fesluca oiiiia ; flies bred May and Juno 



* Van Vollenhoven has just given us the life-history of this S2)ecies — which 

 is not a gall-maker — in the • Tijdsohrifl' (vol. xix. p. 'ZQl).
