Bred by Mr. G. C. Bignell, April 20th, 1882, from 

 half-grown larvae of Tceniocampa instahilis. 



This insect may he said to belong as much to Casinaria 

 as to Limneria, being without metathoracic arese, and the 

 inner orbits scarcely emarginate ; ])ut the aculeus is 

 longer than in any Casinaria I can find described. The 

 cocoon is chocolate, with central whity-brown zone. 



Limneria rufa, n. s. 

 Abdomine pedibusque, maxima ex parte rufis. 



Head transverse, narrow behind the eyes ; antennae 

 rather more than two-thirds the length of the body ; 

 eyes rather deeply emarginate against the antennae ; fore- 

 head without keel or groove. Thorax slightly longer than 

 high, rather coarsely punctured ; parapsides slightly 

 defined ; the depression behind the anterior margin of 

 the mesopleura bounded by a fine distinct line ; meso- 

 pleura with scattered punctures ; interstices reticulate ; 

 scutellum keeled only at the base ; supero-medial area of 

 metathorax distinct, transverse, open behind ; lateral 

 areae divided ; postero-medial almost flat, with indistinct 

 concavity ; spiracles oval. Abdomen compressed ; post- 

 petiole about twice as wide as the petiole, rather longer 

 than wide ; petiole a trifle longer than the post-petiole ; 

 the abdomen hardly compressed. Areolet with a short 

 petiole ; recurrent nervure received just beyond the 

 middle ; transverse anal not divided ; transverse dis- 

 coidal divided below the middle ; aculeus of female 

 hardly exserted. 



Black ; palpi yellow. Legs red ; coxae, trochanters, 

 apex of front tarsi, middle and hind tarsi, fuscous ; hind 

 tibiae more or less fuscous-red ; extreme base of all the 

 tibiae with a minute white spot above in the male, obsolete 

 in the female ; tegulae white ; nervures and stigma 

 black. Abdomen red ; petiole brown ; sides of petiole 

 and 2nd segment slightly fuscous ; anterior half of 

 venter fuscous. Long., male and female, 9 mm. 



Bred by Mr. G. C. Bignell from Bombi/x quercus. The 

 Ichneumon larvae emerged from the living caterpillars. 

 The cocoon is oval, black, and granulated on the out- 

 side.
