L/ssofio/,7.] BRITISH ICHXEUMONS. 225 



seded Holmgren's name because Z, {Cryptopimpla) errahinda, Grav. was 

 previously described, and in no way to erect a new species. 



This species may be known by its small size, gently curved basal seg- 

 ment which is not or very indistinctly canaliculate, its red hind coxae and 

 trochanters, short and almost parallel-sided basal segment, elongate terebra 

 and pale $ face. 



It is much the commonest of the Segmentator-^xow^ in Britain, though 

 not introduced till 1884, when Bennett found it about Guestling, near 

 Hastings (Trans. Ent. Soc. 1884, p. 433.) I possess females taken at 

 Whitby in the middle of August by Beaumont, Felden in Herts by Piffard, 

 Shere in Surrey by Capron, Lyndhurst in the middle of August by Adams, 

 the New Forest by ]Miss Chawner ; and have m\self taken both sexes in 

 the middle of August in my father's greenhouse at Ryde in the Isle of 

 Wight, males at Oxshott in the middle of julv on Heracleum flowers and 

 one female as late as 27th September, 1902, on ragwort flowers in the 

 Bentley ^^'oods, near Ipswich. Bridgman records it from Brundall, near 

 Norwich.

 except sometimes in 9 ; 6 ^^ith a small line beneath the radix also pale 

 stramineous ; pleurae punctate and the longitudinal costae of the areola 

 sometimes fine and in part evanescent. Scutellum black. Abdomen 

 with the basal .segment of 9 a little longer than the hind coxae ; three 

 basal segments alutaceously punctate ; second to fourth of ^ apical ly 

 and in 9 sometimes testaceous-margined ; terebra as long as the body. 

 Legs rufescent with the hind tarsi and in J apices of their tibiae, their 

 coxae above or nearly entirely and the anterior coxae of 9 iii P'lrt,
