246 BRITISH ICHNEUMONS. \Anomalon 



7. bellicosum, Wes])i. 



Anoiiiiilon bcllicosiiiu, Wesm. Bui. Ac. Brux. 1849, p. 124 ; Holmgr. Sv. Ak.

Head black witli the palpi, mandibles, clypeu.s, cheeks, face and vertical 

 dots flavous. Antennae piceous, rufescent beneath, with the scape en- 

 tirely clear testaceous. Thorax black, of 9 usually with the pleural 

 sutures and apex, or sometimes whole, of metathorax red. Abdomen red 

 with only the second, sixth and seventh segments discally black. Legs 

 red, with anterior coxae and trochanters flavous; hind legs with most of 

 coxae, trochanteral base and tibial apices black, their tarsi flavous with 

 metatarsal base rufescent. Wings flavescent, with stigma and tegulae 

 rufescent. Length, 13-16 mm. 



It is usually somewhat smaller than A. xant/iopiis, from which it is best 

 known by the entirely pale scape, though the scutellum is more convex 

 and the abdominal nigrescence less extensive. 



Not a common species, though widely distributed, in north and central 

 Europe; Tosquinet says it occurs in August and September in Belgium, 

 and Brischke bred it in Prussia from Sphinx pinasiri as well as {^teste 

 Bridg.- Fitch) Demas coryli. It appears to be a soutliern species in Britain 

 and I have not seen it from north of the Thames; Bignell took it at Ivy- 

 bridge in Devon on 12th August; I have it singly from Shere (Capron) 

 and Guestling (Bloomfield), though it is probably not rare in the New 

 Forest, whence IMiss Chawner has kindly sent me a series and Bradley 

 exhibited specimens thence, named bv Bignell, at a meeting of Birm. 

 Ent. Soc. (i8t]i Mav, 1896I; Adams takes it in his Lyndhurst garden in 

 July. 



LABRORHYCHUS, Forster. 

 Forst. Verb. pr. Rheinl. 1868, p. 146; Blaptocaiiipus, Thoms. O.E. xvi. 1765. 



Little more than a section oi Anomaloii with the anal or parallel ner\ure 

 emitted at or above the centre of the brachial cell, which is itself sub- 

 parallel-sided and not, as in that genus, distinctly explanate towards its 

 apex. The species are more slender and, as a rule, neither so large nor 

 so stout. 



The main distinction of Thomson's genus appears to be the position 

 of the anal nervure, which in place of being emitted from distinctly above 

 the centre of the brachial cell as in typical Lahrorhychiis species, is emit- 

 ted from its centre ; the synonymy of Wesmael's two species, here pro- 

 posed, reduces Thomson's genus to little more than specific rank and as 

 such I have considered it in the following table.
