ALLOPLASTA. 22% 



claws somewhat large, not pectinate, of c? obsoletely and of 5 

 distinctly ciliate beneath. Areolet subrhomboidal, sessile or 

 shortly petiolate ; upper basal emitted from median nervure very 

 distinctly before the lower basal ; internal cubital sharply angled 

 centrally, with the nervelet often distinct ; first recurrent nervure 

 of lower w T ings intercepted at or a little below the centre. 



Range. Europe, Simla. 



In my 'Ichneumons of Britain ' (iii, 1908, p. 226) I suggested that 

 Meniscus murinus, Grav., and M. plantariiis, Grav., were probably 

 of a distinct genus from the remainder of the species there tabu- 

 lated, on account of their finely setiferous and not pectinate claws 

 and of their very distinct economy ; but I refrained from employing 

 burster's inadequate and typeless genus, until further elucidated. 

 This had, however, been already done by Cameron, without either 

 his knowledge or mine (I had not looked up Indian references for 

 British insects and he had little knowledge of Fiirster's genera,, 

 nor apparently of the abundant European Meniscus murimts); 

 consequently, I think, one is justified in now employing Alloplasta 

 in nomenclature, with type Lissonota murina, Grav., Ichn. Eur, 

 iii, p. 99 ( = Trichopimpla, Cam.; type, T. pilosa). Ashmead's 

 characters for this genus are entirely valueless. It differs little 

 from the rare Arenetra, Holmg., in the pilosity of the head an d 

 thorax, but distinctly in that of its typically nitidulous basa 

 abdominal segment, and in its evenly punctate metathorax, which 

 in Arenetra is distinctly rugose throughout and not punctate ; 

 from Meniscus it is distinguished by the structure of the claws.

Trichopimpla pilosa, Cameron,* Zeits. Ilym.-Dip. 1903, p. 303 ( $ ).. 



$ . An entirely black species, with elongate pilosity, and the 

 legs alone rufescent. Head stout, with the frons closely punctate 



and in the centre transversely 

 and indistinctly strigose ; vertex 

 closely punctate, more sparsely 

 laterally ; face closely and ru- 

 gosely punctate, with the cly- 

 peus less closely and strongly 

 and more nitidulous; centre of 

 inner orbits narrowly, and the 

 apical third of clypeus, rtifes- 

 ceut ; mandibles and palpi 

 black, with the apical teeth 

 ferruginous. Tliorax closely 

 and uniformly punctate on the 



on the metathorax ; metanotum 

 more coarsely punctate apically, and with distinct though 

 short traces of a transverse costa at its apical angles; pleura)-
