Black with the hind coxae concolorous, underside of scaj)i' and the 

 lei^s stramineous with the liind femora and apici's of abdominal segments 

 fulvous; areolet obHcjue, emitting' recurrent nervure beyond its centre. 

 Length, 4 mm. 



Extremely like the last species but certainly distinct in its posteriorly 

 broader head, longer antennae with scape flavidous beneath, the more 

 parallel-sided aret)la with costulae only basally traceable, stramine()us legs 

 with only the hind femora rufescent, hind coxae black and apices of their 

 tibiae and tarsi subnigrescent, the paler stigma and obliciue areolet, emit- 

 ting recurrent very distinctly beyond its centre. 



Both sexes were described from Prussian specimens bred from larvae 

 of Xiniatus Valisnicri and a species of Crvptocampus, and it does not 

 appear to have been since noticed. I possess a couple of males, described 

 above, captured by the Rev. T. A. Marshall at Botustleming near Hatt in 

 Cornwall and bred on i8th August, 1903, by Tonge from an unknown 

 Surrey host; and I captured a female at Alildenhall on 25th September, 

 1907, by sweeping reeds in a marsh. 



TRANOSEMA, Thomson. 



Thorns. O.E. xi. 1887, 1137. 



Head short with the lateral clypeal foveae small. Thorax gibbulo- 

 cylindrical, with mesopleural speculum shining or dull ; metathorax 

 smooth or rugosely punctate, with distinct costulae. Abdomen fusiform 

 and black ; petiole narrower and a little longer than the subquadrate 

 postpetiole, with its lateral sulci and the latter's lateral scrobes distinct ; 

 second segment not longer than broad, with spiracles before its centre ; 

 terebra stout and exserted, at least as long as basal segment. Legs 

 normal and red, basally black ; not white-marked. Wings with the 

 areolet distinct and irregular ; nervellus oblicjue and hardly geniculate. 



By no means a distinct genus, though it can only be confused with 

 Oniorga among those with oblique nervellus, and therefrom it is recognised 

 by the possession of distinct lateral petiolar sulci and scrobes, subparalli-1- 

 sided postpetiole, not elongate second segment with spiracles before its 

 ct'Utrt' and the tibiae noi white-marked.
