versed by two linear arched bands of black ; a sub-apical oval ocel 
with rufous border, and for pupil a line of white : some apical spots 
white. Posterior wing mth two large ocelli bordei d v/ih black, c 
touching the costal margin at its middle, marked by a semi-circu 
white line ; the other towards the anal angle, marked by a round sj

a line of white : the outer margin broadly rufous, its inner bore 
zigzag. 
Female dark rufous-brown . Anterior wing crossed near tlie mid(

I am indebted to Mr. Belt for this very interesting addition to ii 
collection. The male on the upper-side scarcely differs from 0. Berecy

This species alone has a female very dissimilar in the colour and positi(

ON SOME BRITISH CYNIPID^, 
BY THE RET. T. A. MAHSHALL, M.A. 
( Continued from Vol. iv, p. 275.) 
In former papers I have endeavoured to enumerate British specie 
as far as the genus Aulax, inclusive. I have now to deal with tb 
remaining sections, (1) inquilii^j^, (2) aphidivor^, and (3) pabj 
siTiciE. The first of these consists in Britain at present of the genu 
Synagus alone. These insects form a natural link between the gal 
makers and the carnivorous groups that follow. They are foun 
abundantly in all galls, upon the interior substance of which they ar 
supposed to feed in the larva state, although they contribute uothinj 
to the formation of the excrescence. Their position in life, is, therefore 
similar to that of the cuckoo-bees, Apathus, &c., which are not carni 
vorous, but avail themselves of the labours of others for support. Thi 
real proprietor of a gall infested by Synergi never arrives at maturity 
so far as I have been able to observe. The reason of this seems obscure 
Several inquilines will emerge from a gall of G. lignicoh, intended onlj 
to accommodate a single Gynips. They cannot have sustained them- 
selves on the flesh of the Gynips, which would be insufficient for more
