164 THE ENTOMOLOGIST S RECORD. 
examples was domiciled in the nest of I’. rufa, the other in that of 
Lasius fuliginosus. This spider was first described, from ants’ nests, in 
Sweden, by the late N. Westring, under the name of Hahnia pratensis, 
C. L. Koch. Dr. T. Thorell includes it (Syn. Hurop. Spiders, p. 165) 
in his genus Cryphoeca. M. Simon, however, distinguishes it from 
this genus, and makes it the type of group A of his genus Tetrilus 
(Hist. Naturelles des Araiynées, 2nd ed., 1898, p. 269). The palpal 
development of Tetrilus arietinus (gf) is among the most extraordinary 
of the multitudinous forms of that part of their structure among the 
Araneidea. ‘This is its first record as a British spider.—Rry. O. P.

LisTRODROMUS QUINQUEGUTTATUS, GRAV., BRED FROM CYANIRIS ARGIO- 
Lus.—On September 4th last I found five larve of Cyaniris aryiolus 
feeding on the buds of ivy bloom, in a garden near Chalford, in 
Gloucester. They all pupated on the 6th and 7th of the same month. 
On April 16th one male emerged, on the 27th a female, whilst on the 
latter date a third pupa produced an ichneumon. On April 28th the 
two remaining pupe produced similar ichneumons, all females. These 
were sent in due course to Mr. Morley, and he now reports as follows: 
‘““Thespecimenssent are Listrodromus quinqueguttatus, Gray., 2? . Graven- 
horst first described the g (Ichnewmonologia Huropaea, i., 626) under 
the name Ichneumon quinqueguttatus, and the @ (loc. cit., 899) under 
the name J. nycthemerus. Under the latter name Desvignes (Cat. Ich. 
in the British Musewm) again described the g in 1856. Wesmael 
(Tentamen= Nour. Mém. Ac. Bruw., 1844, p. 146) added somewhat to 
Gravenhorst’s description of the 2, and created the subgenus Listro- 
dromus, which he supplemented and also figured in Bul. Ac. Brua. 
Annexe, 1853-54, p. 139, pl. u., fig. 13, and surmised that quingue- 
guttatus was its g. It appears to be a very rare insect throughout 
Europe (though I cannot vouch for its continental occurrence during 
the last ten years). Gravenhorst knew only one ?, which he first 
described in his Monoyraphia Ichnewmonun Pedemontanae Regionis 
(1820). Wesmael says it is very rare in Belgium, where he had not 
(in 1853) seen a specimen for 80 years, and the three ? 2 previously 
taken were from the vicinity of Brussels. Bridgman and Fitch, in 
their papers on Ichneumons (/ntomologist, xiv., p. 182), give a meagre 
description, and seem to know it only from Desvignes’ specimens 
(both g and ¢?) as British, having never met with it themselves. I 
am consequently glad to find that Bignell (Z’rans. Dev. Ass., 1898) had 
once bred it—and from the same host—on July 14th, in south Devon, 
though which sex is not stated. I fear you have not also bred the ¢ — 
which among other points may be distinguished by having the 
posterior tibiz for the most part yellow, not red—with the 9? This 
would be most interesting.” —(Mrs.) Mary B. Repmayne, Chetwynd

Euchloé cardamines with a conspicuous black spot in the centre of each
