pale testaceous ; hind legs infuscate, with rut'escent markings. 

 Metanotum subnitidulous and glabrous, with very sparse and fine 

 punctation, and complete though indistinct area3 ; basal area 

 cordiform and twice as long as broad, areola subparallel-sided and 

 also twice as long as broad, with the strong cosfculae emitted 

 near its base ; petiolar area finely reticulate and very distinctly 

 discrete.

Tribe CAMPOPLEGIDES. 



This tribe comprises probably half the species of 

 throughout the world ; its less conspicuous members are 

 abundant everywhere, both as parasites of the first degree and 

 as hyperparasites, through numerous species of BKACONID^E, 

 on the smaller Lepidoptera. It is easily recognised from the 

 following tribes by its comparatively narrow stigma and radial 

 cell, and the irregularly triangular or wanting areolet ; from the 

 preceding tribe it is known by the second recurrent nervure always 

 emanating beyond the submarginal nervure, and by its simple 

 tarsi and metathoracic apex. Most of the species are recorded 

 from temperate regions, where they are appallingly numerous, 

 and no doubt can be entertained that we at present know but a 

 tithe of those occurring in the Himalayas. Certain genera, 

 especially those lacking the areolet, do not appear uncommon at 

 lower altitudes, though they have been but little collected, on 

 account of their inconspicuous size. Authorities are by no means 

 agreed respecting generic values in this tribe at present, and, I 

 think unfortunately, Forster's typeless subgenera have become 

 lai'gely adopted as genera by recent authors. In any case, the 

 ponderous mass of descriptions must be subdivided and, since 

 nothing but minute distinctions are available, the following 

 table may be found of some assistance in discriminating between 

 our indigenous genera. 



I am glad to have had the opportunity of examining the 

 majority of Cameron's typical specimens of Limnerium, since it 

 would have been quite impossible from his isolated descriptions 

 to have conceived the least idea of their systematic position ; 

 he appears to have employed the genus in its very widest sense.
