BRITISH ICHNEUMONS. 



c?. Head black ; palpi, mark on mandil)les, sides of clypeus and 

 internal orbits narrowly, quite white. Antennae black, the flagellum 

 ferrugineous beneath. Thorax black, with normal marks at radix puncti- 

 form, white ; areola transverse. Apex of scutellum white. Abdomen with 

 grey pubescence ; black with apical margin of second and third segments 

 paler ; sculpture as in 5 . Legs black ; the anterior with tarsi and tibiae 

 externally white, and whole base of latter also white, their femora internally 

 stramineous ; posterior tibiae also sometimes basally, and all the calcaria, 

 quite white. Wings somewhat clouded, stigma black, tegulae either 

 piceous with a white dot, or entirely white ; sides of the areolet almost 

 coalescent above. Length, 10-12 mm. 



The female much resembles that of J/, bimaculatorius in the filiform 

 flagellum, which is a little attenuate towards the apex, as well as in shape 

 and size ; but it is distinct in the generally punctate central area of the 

 post-petiole being only a little broader than the lateral ones, the gastrocaeli 

 and thyridii small and more deeply impressed ; the male is at once dis- 

 tinguished by its black anus and antennae above. 



Uncommon ; taken at Coombe Wood, in July (Stephens). Captured at 

 Plymouth Hoe, 28th September (Bignell). Rev. A. Thornley has given 

 me a male, taken in the New Forest, in August, 1898. Gravenhorst says 

 that, as its name implies, it lives among undergrowth, in June ; it has been 

 bred on the Continent, where it is widely distributed and extends to Spain, 

 from Lithosia quadra and Trachea piniperda.

Head closely punctate and pubescent, hardly narrowed behind the eyes ; 

 temples broad and convex ; clypeus apically truncate, of S laterally white- 

 dotted ; palpi pale ; the frontal orbits, and in 3 the facial also broadly, 

 white. Antennae apically attenuate, rufescent at least towards the apex 

 beneath ; of $ centrally white above, with sixth flagellar joint sub-quadrate. 

 Thorax a little narrower than the head, black ; sometimes with pronotum, 

 lines before and beneath the radix, white ; metathorax finely rugose, areae 

 complete ; areola sub-cordiform, apically deeply emarginate. Scutellum 

 stramineous. Abdomen black with the central incisures rufescent ; ? with 

 seventh segment dorsally white ; post-petiole sub-punctate or scabriculous, 

 laterally coarsely punctate ; second and third segments somewhat strongly 

 punctate especially between the small, foveiform, triangular gastrocaeli ; 

 terebra slightly exserted. Legs normal, red, hind coxae simply punctate 

 beneath ; coxae, trochanters, hind tarsi, apices of their tibiae and often of 

 their femora, black. Wings a little clouded ; stigma and tegulae piceous, 

 latter sometimes pale-dotted. Length, 7-10 mm. 



This species is similar in size and conformation to /. albosigna/us, Grav., 

 with which it was so long confused ; the head, however, is shorter and 



1 Ichneumon balearicus, Kriecli., which is considered a Rood species by Schiniedcknecht, was first 

 regarded by Berthoiiinieu as a variety oi ApacUticus bcUicosus and subsequently (Ann. SoC. Fr. 1896, 

 p. 396) to constitute, with Ichneumon nudicoxa, a variety of Barichnetimon biluntdatus.
