DESCRIPTION OF A NEW SPECIES OF TORYMUS FROM SCOTLAND, 
WITH NOTES ON OTHER BRITISH SPECIES OF THE GENUS, &c. 
BY P. CAMERON. 
Torymus campanula:, sp. n. 
Green or bluish-green, pilose ; antennae black, the scape on the under-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 tibiae 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-thirds of the 
thorax. 
The S 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. hibernans, Mayr, hut it is a narrower insect, 
the abdomen is longer compared with the thorax, and more compressed, 
the antennse 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. Gustav 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, Verb. z.-b. Ges. Wien, xxiv, p. 123, 4; I find this near Glasgow 
iu galls of Ilhodites eglanterice. 
Torymus tipularum, Zett., Ins. Lapp., 1840, p. 420 ; Mayr, 1. c ., 
Ill, 27 ; Thoms., 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, l. c., 120, 36, 1 found last October oviposit- 
ing at Milngavie in the galls of Neuroterus leniicularis. 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, l. c., 
109, 23, I reared this spring in abundance from the galls of JTormo- 
myia juniper ina collected last year on Clober Moor. It is apparently 
identical with T. amethystinus, Boh., Yet. Ac. Handl., 1833, p. 370 ; 
and Thoms., Hymen. Scand., iv, 85, 10.
