however, satisfy myself that the above are the correct names of these 

 pretty httle creatures. 



In Dr. Capron's collection are both sexes of an insect named Diadromus 

 ienax, Wesm. (Nouv. Mem. Ac. Brux. 1844, p. 210) ; but there are no data 

 to indicate their British origin. They agree very well with the descriptions 

 of that species— the ? of which Thomson says does not possess tricoloured ■ 

 antennae — excepting that the coxae are entirely red and the S pedicellus 

 is not unusually dilated. 



From the same source I possess a 6 and $ named Miseius oculafiis, 

 Wesm., which species should certainly occur in Britain, since it is recorded 

 from all the adjacent countries. The ^ referred to may be correctly 

 named, and appears to belong to Wesmael's var. i. (Tentamen, p. 213), 

 but the clypeus is not in a condition to admit of close examination of its 

 apical central tooth, which feature at once distinguishes this genus with 

 its single species from the remainder of the Phaeogenides. The 5 is a 

 Phaeogenes with no relation to Misetus ; it is probably referable to P. 

 muricifer, Holmgr. Ichn. Suec. iii. 440, closely allied in coxal structure to 

 P. ophthalmicus, but with the basal segment black. No data are affixed 

 and the specimens' origin unknown. 



Ichneumon eryihrocerus, Gr. (Mem. Ac. Sc. Torin. 1820, no. 102 ; I. E. 

 i. 610, excl. var.) is indicated in Marshall's MS. notes, without query, as 

 taking precedence to Oiorhinus pallipalpis, and the description appears to 

 leave but little doubt as to the correctness of the synonymy, in spite of 

 Wesmael's remarque critique (Mem. couron. Ac. Belg. 1859, p. 76). 



'■'■ Ischnidinm (formerly Ischnogaster) alhibucca \sic\, Kriechb." Ent. 

 Nachr. 1890, p. 153, is also indicated Qoc. ciL) as having been ascertained 

 to be British, though apparently only previously known from Bavaria. 

 The genus (which should be called JVofose/nus, Forst. Verb. pr. Rheinl. 

 1868, p. 194, according to Ashmead's synonymy) contains but this species, 

 and may be distinguished from the remainder of the Phaeogenides, among 

 which it is allied to Ischfius, in its hardly convex scutellum, linear and 

 sub-acute abdomen, complete areolet and metathoracic areae. 



Among the Irish Ichneumonidae recorded by me in E.M.M. 1902, p. 54, 

 Col. Yerbury sent what I am of opinion is Colpognathus arniafus, Thorns. ; 

 it was omitted from the list, however, because I was not satisfied as to the 

 presence of the coxal tubercles, in which it differs from the remainder of 

 the genus. It was unfortunately damaged in re-examination, and the 

 abdomen lost ; one hind coxa, however, remains, and this certainly appears 

 to bear a globose apical tubercle, but the antennae are distinctly bicoloured 

 and not tricoloured as described in the great Opusc. Ent. xv. 1636.
