214 BRITISH ICHNEUMONS. \_AniIasta 



Bridg. -Fitch differentiate this species from the rest of the broad genus 

 Limneria by the characters : — Abdomen red with petiole alone black ; 

 scape immaculate beneath ; hind femora red ; tibiae rufcscent and not 

 infuscaie towards their base ; front and hind coxae black ; terebra about 

 as long as basal segment, not very short. 



It was originally bred by Bignell from living larvae of Boinbyx querais ; 

 and the cocoon is described as oval, black, and granulated on the outside. 

 In his "Note on Limneria riifa, Bridg." (Entom. 1883, p. 6q), Bignell 

 says that to breed L. rufa "it is necessary to obtain the larvae of Bomhyx 

 querciis this month (INIarch) ; for this reason, the ichneumon larva leaves 

 its victim before it moults for the fourth time. When it does leave it, it 

 forms an oval, black, rough cocoon under the unfortunate caterpillar on 

 the inside of which it had been feeding. The writer obtained the first 

 infested larva when at Torquay on 14th March, and bred the parasite on 

 5th April, 1882." The only specimen I can ascribe with any degree of 

 certainty to this species is a male of but 8 mm., which agrees with the 

 description in every way except that the tibiae are not white-marked ; it 

 was bred from an unknown host on 21st May, 1902, by Cross in the New 

 Forest ; the cocoon from which it emerged is black, but with a white 

 central girdle.

Black with the abdomen more or less narrowly red in the centre and 

 terebra very slightly exserted ; femora fulvous ; coxae and trochanters 

 whitish, with only the hind coxae black to beyond their centre ; tibiae 

 and tarsi flavidous, hind ones stramineous with the former apically and 

 obsoletely before their base, and apices of the tarsal joints, infuscate ; 

 antennae pilose; metathoracic carinae subobsolete; areolet oblique and 

 apex of discoidal cell strongly acute below ; ventral plica whitish ; scape 

 and pedicellus testaceous beneath. Length, 5-6 mm. 



The very pale ventral plica, coxae and underside of antennal base are 

 distinctive. 



I retain Holmgren's name for this species, since Thomson thought 

 Gravenhorst's male distinct ; but if, as he supposes, it be referable to 

 Ulesicampa, no reason stands for a new name in the present genus. 



A female was first taken at Tarna in southern Lapland on 28th July 

 by Boheman and at Yddinge in Sweden by Thomson ; in France by 

 Gaulle and twice during August in Belgium by Tosquinet ; Chapman 

 has sent me a male he has bred from Fumca sp. at Locarna in Ajjril, 

 1900, differing in no particular from the female ; but Brischke's Konigs- 

 berg male with pale orbits seems very different. This species is \ery 

 uncommon with us ; Bridgman introduced a female with entirely red 

 third segment (Trans. Ent. Soc. 1881, p. 160), bred by Barrett from 

 British Ebidea slachydalis, but neither he nor Bignell captured it. I 

 possess two pairs, bred by Bignell in Devon on i8th August, 1884, 

 from Gracillaria syringe/la; captured on 29th July, 1900, at Tostock by 

 Tuck ; at Much Markle in Hereford by Yerbury at the end of May, 

 1902 ; and swept by myself on 22nd August in Tuddenham Fen.
