Thymaris.] BRITISH ICHNEUMONS. 279 



A single specimen is said {loc. ci/.) to have been captured by Mr. 

 Thouless, in Norfolk, in 18S4; and its author adds (Trans. Nori. Soc. 

 1893, p. 618) that this was found "in the neighbourhood of Norwich. It 

 is the only specimen I have seen of this genus taken in England." I 

 know of no other records and the female is still unknown.

 Forst. Verb. pr. Ilheinl. 18(SS, p. 168; Aphanoroptra, Thorns. O. E. viii. 736. 



Head oblong-ovate and rostrately produced towards the mouth, with 

 the cheeks somewhat elongate and their costae continuous ; vertex 

 narrow, frons not convex, centrally canaliculate and impressed above the 

 scrobes ; clypeus indistinctly discreted and labrum elongately exserted ; 

 mandibles short, broad and margined \\ith the apical teeth obsolete and 

 of equal length. Antennae filiform, not longer than half the body, apically 

 obtuse with the scape hardly excised. Thorax gibbous with the pronotal 

 epomiae large ; notauli short and somewhat deeply impressed ; mesoster- 

 nal sulci laterally deeply impressed and posteriorly bifurcate ; metathorax 

 short, apically truncate with the areae entire and strongly costate ; spira- 

 cles round and approximating the base. Scutellum laterally margined 

 and apically foveate. Abdomen very closely punctate ; apices of the seg- 

 ments not elevated nor nitidulous ; basal segment broad and laterally 

 margined with its discal carinae convergent and extending nearly to its 

 apex ; second and third segments very obsoletely tuberculate ; seventh 

 small and retracted ; hypopygium vomeriform and distinctly extending 

 a little beyond the anus ; terebra curved and distinctly exserted. Legs 

 not slender, somewhat short with the onyches minute and simple. Wings 

 with the stigma broad and triangular ; radial cell broad, discoidal with its 

 lower angle acute and a little longer than the brachial ; areolet entire 

 and irregularly triangular; basal nervure acutely sinuate ; nervellus strongly 

 antefurcal and intercepting far below the centre. 



Thomson remarks upon the relationship set up between this genus and 

 Tryphon by the conformation of the metathorax, petiole and 

 hypopygium.
