DESCRIPTION OF A NEW SPECIES OF TORYMUS FROM SCOTLAND, 

 WITH NOTES ON OTHER BRITISH SPECIES OF THE GrENUS, &c. 



BY P. CAMERON. 



TORTMUS CAMPANULA, Sp. 71. 



Green or bluish-green, pilose ; antennae black, the scape on the umder-side 

 yellow ; the 2nd joint of the flagellum slightly longer than broad. Legs yellowish, 

 the greater part of the coxae and of the posterior femora green ; the four anterior 

 femora with a greenish line on the outer side, and slightly brownish on the other 

 side ; posterior tibia? fuscous, except at base and apex ; the apex of tarsi fuscous ; 

 the calcaria short, scarcely a third of the metatarsus in length. Abdomen com- 

 pressed, longer than thorax ; ovipositor as long as abdomen and two-tbiyds of the 

 thorax. 



The $ has the scape green on the under-side, and agrees otherwise in coloration 

 with the $ , except one specimen, which has the head, thorax, posterior coxae, and 

 abdomen suffused with bronzy splashes. The wings are hyaline ; the costa with a 

 hair-fringe. Length, 2 — 3 mm. 



Of the species in my collection it comes closest in coloration and 

 length of ovipositor to T. hibemans, Mayr, but it is a narrower insect, 

 the abdomen is longer compared with the thorax, and more compressed, 

 the antennae longer, and the spurs much shorter. 



Bred in July and August from the galls of Cecidomyia campanula, 

 Muller ; found in various parts of Clydesdale. Dr. G-ustav Mayr has 

 kindly examined specimens, and has confirmed my opinion as to its 

 being an undescribed species. 



Torymus viridis, Forster, Beitr. z. Mon. d. Pter., 1841, p. 32 ; 

 Mayr, Yerh. z.-b. Ges. Wien, xxiv, p. 123, 4; I find this near Glasgow 

 in galls of Rlwdites eglanterice. 



Torymus tipularum, Zett., Ins. Lapp., 1840, p. 420 ; Mayr, I. c, 

 111, 27 ; Thorns., Hymen. Scand., iv, 95, 26 ; = Torymus pumilus, Eatz., 

 Ichn. d. Forstins., i, 1844, p. 180 ; this I have bred here from the rose 

 galls of Cecidomyia rosaria on willows. 



Torymus sodalis, Mayr, I. c, 120, 36, 1 found last October oviposit- 

 ing at Milngavie in the galls of Neuroterus lenticularis. The ovipositor 

 was inserted at the side, under the flat projecting part of the gall, 

 which was then a little swollen. It would seem to be a good species, 

 and readily distinguished from the other spangle-gall Torymus (hiber- 

 nans) by its shorter ovipositor. 



Torymus juniperi, Linne, Fauna Suec, 408, 1635, sec. Mayr, I. c, 

 109, 23, I reared this spring in abundance from the galls of Hormo- 

 myia juniper ina collected last year on Clober Moor. It is apparently 

 identical with T amethystinus, Boh., Yet. Ac. Handl., 1S33, p. 370 ; 

 and Thorns., Hymen. Scand., iv, 85, 10.
