Hemiteles.] BRITISH ICHNEUMONS. 1 73 



Bridgman says this species is very like H. oxyphimns^ but the wings are 

 not fasciated, the legs are more slender, the basal segment is narrower 

 and not aciculate and the terebra is longer; it a[)pears to differ from 

 H. validicornis in nothing but its slender antennae and longer terebra. 



Taken by Bignell at Exeter towards the end of September ; by Marshall 

 at Sandwich, Milford Haven and Braemar ; by Canon Fowler ; and by 

 Dr. Capron at Shere. It appears to be generally distributed and is 

 probably not uncommon, though at present unrecognized on the Continent. 



OTACUSTES, Forster.

Head transverse and not globose. Metathoracic spiracles large and 

 oblong. Second discoidal cell entire ; areolet internally complete and 

 regular, externally obsolete. Basal segment short and stout. Metathoracic 

 costae entire and its basal sulcus deeply impressed. 



The conformation of the metathoracic spiracles certainly appears to 

 entitle the following species to generic rank. I have no personal accjuaint- 

 ance with this genus, which appears to be very doubtfully indigenous, but 

 would suggest its possible relationshi[) with Plectocrypius grisescens, Grav., 

 from which, however, it sufficiently differs in the elongate metanotum, 

 sub-sessile abdomen and narrow stigma. 



I. breviventris, Grav.

 Sclim. Term. Fiiz. 1897, p. 501, i. 



Head black with the clypeus imperfectly discreted, apically reflexed, 

 obtusely truncate and irregularly dentate. Antennae setiform, rufescent 

 and somewhat shorter than the body. Thorax sub-cylindrical, black ; 

 metathorax elongate, closely and not finely punctate, with complete areae 

 and deep basal sulcus ; petiolar area oblique and discreted. Scutellum 

 black. Abdomen nearly sessile, sub-sericeous, ovate, deplanate, as broad 

 as the thorax, very closely and finely punctate, piceous ; basal segment 

 feebly canaliculate and basally gradually contracted, longer than broad, 

 with the spiracles prominent ; anal styles obtuse and hardly exserted. 

 Legs normal, red ; coxae and trochanters black ; hind tarsi and a[)ices of 

 their tibiae infuscate. Wings clouded, stigma narrow and, like the costa, 

 black ; radix and tegulae whitish ; areolet pentagonal with the outer 

 nervure barely indicated. Length, 6 mm. 



The abdomen is broader, with its basal segment shorter and broader, 

 than in any species ol Hemiteles ; both Taschenberg and Schmiedeknecht 

 thought it worthy of generic position, to which Forster had already raised 

 it, though they merged it in the latter genus. 



Only a single authentic specimen, which was captured in Germany, 

 appears to be known ; the British record rests upon its introduction by 

 Marshall, with no details, in his 1870 and 1872 catalogues.
