164 THE entomologist's record. 



examples was domicilecl in the nest of F. rxfa, the other in that of 

 Lasius fidujinoiitis. Tliis spider was first described, from ants' nests, in 

 Sweden, by the late N. Westring, under the name of Hahnia pratcnsn, 

 C. L. Koch. Dr. T. Thorell includes it {Syn. Eiirop. Spvhra, p. 165) 

 in his genus Cniplwcca. M. Simon, however, distinguishes it from 

 this genus, and makes it the type of group A of his genus Tetrilua 

 {Hut. Xatiirelles ih's Araii/n/'cs, 2nd ed., 1898, p. 269)." The palpal 

 development of Tctrilm arii'tiniis [3') 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. — Eev. 0. P.

LiSTRODEOMUS QUINQUEGUTTATUS, GeAV., BRED FROM CyANIRIS ARGIO- 



Lus. — On September 4th last I found five larvae of Cyamn's aryialu^ 

 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 pupfe produced similar ichneumons, all females. These 

 were sent in due course to Mr. Morley, and he now reports as follows : 

 " The specimens sent are L?.sf/v)f?;v*?»».s- qm'uque(/uttatufi,Gi'H,Y., 2 . Graven- 

 horst first described the ^ [Ichit'timouoloi/ia Kuropaca, i., 626) under 

 the name Ic/nieKuion (pdnqneyuttatiifi, and the ? (loc. cit., 399) under 

 the name /. nycthemertta. Under the latter name Desvignes [Cat. Ich. 

 in the British Museum) again described the <? in 1856. Wesmael 

 {Tentamcn = Nouv. Mem. Ac. Bnuv., 1844, p. 146) added somewhat to 

 Gravenhorst's description of the 2 , and created the subgenus Listru- 

 (Ironins, which he supplemented and also figured in Bid. Ac. Bru.r. 

 Annexe, 1853-54, p. 139, pi. ii., fig. 13, and surmised that qiiinque- 

 (/iittatus was its ^ . 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 Ichnevmonum Pedemontanae Eeyionis 

 (1820). Wesmael says it is very rare in Belgium, where he had not 

 (in 1853) seen a specimen for 30 years, and the three ? ? previously 

 taken were from the vicinity of Brussels. Bridgman and Fitch, in 

 their papers on Ichneumohs (Kntnmoloyist, xiv., p. 132), give a meagre 

 description, and seem to know it only from Desvignes' specimens 

 (both <y and 5 ) as British, having never met with it themselves. I 

 am consequently glad to find that Bignell (Trans. Dec. 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 cT — 

 Avhich among other points may be distinguished by having the 

 posterior tibite for the most part yellow, not red — with the 5 ? This 

 would be most interesting." — (Mrs.) Mary B. Redmayne, Chetwynd
