86 BRITISH ICHNEUMONS. [Phygadeuon. 



of their tibiae infuscate. Wings somewhat clouded ; radix and tegulae 

 white ; radial nervure emitted nearly from the centre of the dull testaceous 

 stigma ; areolet very small, s[)urious nervure wanting, nervellus antefurcal. 

 Length, 2-3 mm. 



The entire petiolar area and small, acute apoi)hyses will render this 

 small species sufficiently distinct. 



It occurs in August throughout the northern half of Europe, and was 

 introduced as British by Bridgman, who found it at Earlham, near Norwich 

 (if. Entom. 1S80, p. 53). I possess examples captured by Ca|)ron, at 

 Shere, and by Wilson Saunders, at Greenings in Surrey, in June, 187 1. It 

 is probably overlooked, or mixed with Heiiiiieles, on account of its small 

 size. 



15. brachyurus, Thorns. 



Phygadeuon hrachyurits, Thorns. O. E. x. 955, i 9 . 



Black ; eyes glabrous ; antennae entirely black. Thorax with the 

 petiolar area discreted and narrow; apophyses wanting. Abdomen centrally 

 red ; basal segment twice length of the terebra, dull and alutaceous, with 

 the spiracles only just behind its centre ; second segment very finely and 

 alutaceously punctate basally. Legs red ; femora not slender. Nervellus 

 opposite. Length, 2-3 mm. 



This species is closely allied to the last-described, but it is stouter, with 

 the areolet larger, the vertex broader, the terebra and basal segment 

 shorter, post-petiole broader, and the conformation of the petiolar area 

 is very distinctive. 



Bridgman sent both sexes of this species for identification to Professor 

 Thomson (cf. Trans. Ent. Soc. 1886, p. 339) from Shere in Surrey and 

 Eaton near Norwich ; he also records it from Earlham, in Norfolk ; and 

 Bignell has found it, early in September, at Crabtree in Devon. I have 

 examples captured by Col. Yerbury, at Woolhope, in Hereford, early in 

 June ; and by Wilson Saunders, at Greenings ; but it has only occurred 

 to me in August, on the Suffolk coast, at Southwold ; and both sexes in 

 the Blythburgh salt marshes, at the roots of reeds. On the Continent it 

 has only been noticed in Sweden.

Head very broad, a little broader than the thorax, not narrowed ver-
