Although this genus is placed by Hartig in his section 1, — •' Area 
radialis angusta, areola basalis," — it is far from exhibiting those 
characters typically. The system of neuration is rather transitional 
between the elongate radial cell of Cynips, with the areolet at its base, 
and the section of Synergus, &c,, — " Area radialis brevis, lata ; areola 
intermedia." 
According to Dahlbom (Onych. och Callasp.Tab. Synopt., ii., p. 5, b.) 
the two usual foveola) at the base of the scutellum are obsolete in 
Bhodites ; this is true of Wi. roscv, but not of JRh. nervosus, in which 
they are faintly indicated. 
These insects seem especially to affect the different sorts of rose- 
trees. The males are much rarer than the females. Pive species have 
been described on the Continent : — roscE, Lin. ; centifolice, Hart. ; 
eglanterice, Hart. ; canines, Hart, {spinosissimce, Taschenberg, nee 
Inchbald) ; and rosarum, Giraud. I have only met with one of these 
in England ; but to them must be added C. nervosa, Curt., which is, 
judging from the descriptions, a distinct species.

Hhodites roscd, Lin. 
Black ; legs reddish, the coxae, trochanters, and base of the femora 
black. Abdomen of the (J entirely black ; wings slightly dusky, the 
base of the radial cell incrassated, and suffused at the edges with 
brown. Abdomen of the $ red, black at the apex ; wings darker than 
those of the 3" > a pale brown tint covers the whole of the radial cell, 
and extends some distance beyond. Petiole (^ $ red. Basal foveolse 
of the scutellum obsolete. Long. 1^ — 2 ; alar. exp. 3 — 31 lin. 
This common insect needs only a passing mention here. Its gall, 
the Bedeguar of the Bosa canina, is infested by several Chalcideous and 
other parasites. (See Zoologist, iv, 1359 ; v, 1G61, &c.) 
Bhodites nervosus, Curt. 
? . " Black, shining, obscurely punctured and slightly pubescent ; 
antennae 1-1-jointed, as long as the body, two basal joints brownish ; 
ocelli very large ; post-scutellum rugose, with three parallel ridges ; 
abdomen very smooth and ochreous, the lower sheath brown : wings 
pale fuscous, iridescent, the nervures brown, edges of the marginal 
cell suffused ; anterior legs pale ochreous, intermediate brown, hinder 
piceous, base of all the thighs darkex', apical joint of tarsi fuscous." 
"July; Dover. Distinguished from G. roses by the large ocelli, 
carinated scutel, dark hind-legs, the absence of the brown splash on 
the costa of the upper wings, aud of the areolet."
