170 BRITISH ICHNEUMONS. [Mehhoris 



2. stagnalis, Holmgr. 



Canipoplex stagnalis, Holmgr. Sv. Ak. Handl. 1854, p. 34, cf ?. Meloboris 

 stagnalis, Holmgr. lib. cif. 1858, p. 101; Thoms. O.E. xi. 1149, <? ? . 



A black species with the legs and abdomen bright red, the basal seg- 

 ment and part of hind coxae black ; abdomen strongly convex with 

 petiole and second segment short ; antennae longer than half body with 

 flagellum very slender and underside of scape red ; brachial cell short 

 and externally subrectangular below; thyridii large, seventh segment of 

 9 excised, j \\'ith anal valvulae large. Length, 5-7 mm. 



A small species with the petiole short, postpetiole transversely sub- 

 quadrate ; radius equally curved in both abscissae and emitted beyond 

 centre of the flavous stigma, areolet regular and emitting the recurrent 

 from its centre ; hind coxae basally black, cheeks short and not buccate, 

 and the 9 face apically constricted. 



I have no doubt that this is the Limneria hydropota recorded from 

 Brundall in July by Bridgman, though that species may also occur with 

 us and is at once known by the irregular areolet emitting the recurrent 

 nervure far beyond its centre. I have three females, captured at (kiild- 

 ford by Butler, by Capron at Shere and by myself in the middle of June, 

 1 90 1, by sweeping rank herbage in Rockland Broad, Norfolk. Abroad I 

 can find no records outside SAveden, where Holmgren found it to be 

 infrequent. 



3. inculcator, Grav. 



Ichneumon Sagittarius, Miill, Prodr. 1776, 159 (?). Canipoplex inculcator, 

 Gr. I.E. iii. 55;i; Blanch. Hist. Nat. Ins. 1840,324,?. Limneria pahidicola, 

 Holmgr. Sv. Ak. Handl. 1858, p. 88 ; Bridg. -Fitch, Entom. 1885, p. 205, i ?. 

 Meloboris inculcator, Thoms. O.E. xi. 1150, cT ? . Var. Canipoplex insidiator, 

 Gr. I.E. iii. 562, i ? . 



Black with the abdomen except basally and legs red ; terebra not 

 extending beyond anus; anterior coxae red ; face parallel-sided; apex of 

 brachial cell acute below; antennae but little longer than half body, with 

 Hagellum attenuate; thyridii obsolete and the ^ anal valvulae normal. 

 Length, 6-7 mm. 



This species, as I understand it, has much the facies of Phohocampa, 

 though with the vertex much broader, the nervellus vertical and hind 

 tibiae not white. I find Dr. Capron has placed a pair under the name 

 Limneria insidiator in his collection, which differ in little but their infus- 

 cate anus ; this name has not been revived since given to two central 

 European insects by Gravenhorst in 1829 and the present synonymy 

 appears correct as far as one can judge from his description. 



LifUfieria pahidicola was known as British to Marshall in 1870; it is 

 recorded from Felthorpe in Norfolk during June by Bridgman, who does 

 not appear to have known L. insidiator, though Bignell on the contrary 

 gives the latter alone as occurring at Plym Bridge and Bickleigh in 

 August. I have typical females from Bolt Head (Marshall), Shere 

 (Capron), Wicken Fen in Cambs and Bentley Woods near Ipswich in 

 June, and on Hcracletini flowers near Milton in Hants at the end of July ; 

 both sexes of the var. insidiator occurred on marsh plants with the typical 

 form at Wicken and the Bentley Woods, as well as at Barton Mills,
