INTRODUCTORY PAPERS ON ICHNEUMONIDiE. 101 



a. Antennae of female white-marked towards the base; supero-medial 

 area of metathorax wider than long. - 1. leucocera, S Ymes. 



h. Antennae not white-marked ; supero-medial area not shorter than 

 wide. ------- 2. cruentata, 3 lines. 



The species of this genus, so like Limneria, are easily distin- 

 guished by the eyes being rather densely clothed with short stiff 

 pubescence. C.Jiavipes, Brischke, is added to the British list at 

 Trans. Ent. Soc. Lond., 1882, p. 149. C. cruentata has been 

 bred by Mr. Bignell from Anisopteryx cescularia. Brischke bred 

 his C. elachistce from an Elachista, which mined the leaves of 

 Phleum pratense.

This genus is easily distinguished by the horn- or tooth-like 

 termination of the clypeus. Holmgren describes seven species 

 in his ' Monographia ' ; Tschek includes ten and S. ebeninus, Gr. 

 in his 'Die Osterreichischen Sagaritis-arten ' (Verb. z.-b. Gesell. 

 Wien, xxi., pp. 45-53). We are convinced there are several 

 species mixed up in S. zonata and S. latrator. Gravenhorst says 

 the aculeus of latrator (which he describes as one -fourth the
