172 BRITISH ICHNEUMONS. \_Meloborts 



Holmgren says it occurs in marshy places on the banks of lakes and 

 rivers throuj^^hout Sweden, but it does not seem to have been recorded 

 elsewhere. Tiie only mention of it in Britain is the exhibition of an 

 example from Woking (Meeting Ent. Soc. 7th Sept. 1881), where it was 

 found on ist August. I possess but iour males and two females, all 

 swept in the most marshy spots on the Norfolk and Suftblk coast, upon 

 reeds growing in brackish water at Southwold thrice, at Holme on Statice 

 limoninvi, investigating a salt-marsh plant at Aldeburgh, and once in 

 Barn by Broad near Lowestoft during June, July and August. 



6. ischnocera, Thorns. 

 Meloboris isclinoceni, Thorns. O.E. xi. 1151, J ? . 



Black with the abdomen centrally and the legs red, with all the coxae 

 and the hind trochanters black ; seventh segment of 9 subincised and 

 terebra nearly half length of abdomen. Length, 5 mm. 



The antennae are black, with flagellum filiform and slender, calcaria 

 small, areolet broad, cheeks subbuccate, pleurae hardly punctulate, all 

 the coxae and hind trochanters black, abdomen with the third segment 

 entirely, the second except its base and part of the fourth, red. 



It was described from Lund and is not uncommon on the Continent, 

 where (Jaulie has found it in France and Tosquinet during June and July 

 in Belgium. It was, therefore, likely to occur with us and Capron cor- 

 rectly named several females and a male in his Surrey collection ; I took 

 an analogous male by sweeping in Tuddenham Fen in June, 1908, and 

 in the middle of the following August found another on marram grass on 

 the Lowestoft denes in northern Suffolk. 



7. crassicornis, Grav. 



Campoplex crassicornis, Gr. I.E. iii. 565, ? ; Boie, Weigm. Arch. 1836, <? ? . 

 Linmcria crassicornis, Holmgr. Sv. Ak. Handl. 1858, p. 67, ? ; Marsh. Ent. Ann. 

 1874, p. 143, c? ; Brisch. Schr. Nat. Ges. Danz. 1880, p. 163; Bridg. -Fitch, Entom. 

 1885, p. 206, J ¥. Meloboris crassicornis, Thorns. O.E. xi. 1151, c? 2. 



A black species with the centre of the abdomen broadly and the legs 

 red ; all the coxae and the hind trochanters black with hind tarsi apically 

 infuscate, mesopleurae somewhat closely punctate and areolet small ; 

 mandibles black or ferrugineous ; antennae hardly longer than half body, 

 terebra nearly half length of abdomen, and calcaria somewhat elongate. 

 Length, 5-10 mm. 



At once known by the entirely black coxae and stout antennae. 



Hope sent this species from Netley to Gravenhorst, who knew it from 

 Germany, France and Hungary, and it is not rare in Sweden ; Brischke 

 bred it in Prussia from Hadaia siiffuriincula ; he is said by Dalla Torre to 

 have also raised it from Ncmahis Vallisnurii ; and Gaulle gives Nonagria 

 /j;^/((?<' as another host. There are few British records; Marshall found 

 it on the banks of the canal near Leicester (Ent. Ann. 1874, p. 143) and 

 Bignell at Bickleigh during May and August. Both sexes are recorded, 

 probably erroneously, from Oxj'plilus iciurii (Proc. S. Lond. Ent. Soc. 

 1896, p. 86); but its more probable hosts are such noctuae as Leucania 

 lithargyria, whence Parfitt bred it (Entom. 1881, p. 140); and to which 

 Bridgman, who took it at Earlham near Norwich, adds (Trans. Norf. Soc. 

 1894, p. 620) Plusia inicrrogalionis and Grapholilha campoliana.
