Ophiori] BRITISH ICHNEUMONS. 277 



Belgium during May, while Gaulle says it has been found in France and 

 Kirchner bred it from Bomhv.x MUhauseri. Giraud raised it from Calli- 

 viorpha dominuld (Ann. Soc. Fr. 1877, p. 406), probably in Austria. It was 

 known as British to Curtis and Dcsvignes; and Marshall gives it (Ent. 

 Ann. 1874, p. 124) as bred by him from Bomhyx qmnus, L. It is, how- 

 ever, extremely local with us and nearly confined in my experience to the 

 New Forest, whence Miss Chawner has kindly given me four examples 

 and IMr. Adams two, both from his Lyndhurst garden on 20th I\Iay, 1901, 

 and 2nd June, 1907. While strolling through Briken Wood there on loth 

 June, iQii, I was so fortunate as to net a beautiful female, hovering in 

 the sunshine about some scattered bushes in a glade. Elsewhere I have 

 received for determination a single male, taken in Pelham Wood in Lines., 

 by F. W. Sowerby during Ti^'hp. lOoq; a single example caught by W. 

 Ollis about Hastings on AJay 5th, 1907 ; and I possess one in Capron's 

 collection, possibly from Surrey.

A piceous-red species, profusely black-marked. Head closely punctate, 

 with temples as broad as eyes and vertex elongate. Antennae fulvous, 

 slightly longer than body and not slender. Thorax closely punctate, 

 with the scutellar region and sutures black; notauli subobsolete; meta- 

 thorax short, its notum abruptly declived beyond the centrally sharply 

 elevated basal transcarina, irregularly rugose with no discreted posterior 

 central area ; sides of mesosternun^i with an acute apical tubercle. Scutel- 

 lum acutely carinate laterally. Abdomen extensively nigrescent, often 

 only discally rufescent before the base, petiole and anus usually black ; 

 generally with petiolar base and hyperstylus, the nodose second segment 

 at base and apex black ; petiolar membrane hardly reaching centre ; tere- 

 bra black and hardly exserted. Hind coxae black-marked, or apices of 

 all coxae and base of trochanters black. Wings strongly flavescent with 

 stigma, costa, tegulae and radices fulvous ; nervelet wanting ; lower basal 

 nervure a little antefurcal, the upper parallel with brachial cell which is 

 not convergent with it; radius simply and abruptly curved, and incrassate, 

 at its base ; nervellus intercepted somewhat below its centre. Length, 

 18-20 mm. 



Similar to C>. ~rti/ria)sus in conformation and the infumate-testaccous 

 wings, but larger (Thorns.), with antennae a little longer (Grav.) ; though 

 distinct from all the preceding species in its nodulose basal si\gnients, and 

 the both curved and incrassate radial base. The parallel brachial nervure 

 and lack of nervelet instantly distinguish it from (>. loni^igina, which 

 appears to connect this and the last species with the more typical ones ot 

 this genus. 



Distributed over the greater part of Europe, but always scarce; singly 

 in Thuringia (Schm.) and Linul (Thoms.) ; Germany and Hungary 

 (Grav.); N'ienna (Kirchner); and bred in France from Scopflosoma sa/e/-
