Schizopvga^] BRITISH ICHNEUMONS. 137 



size; no one appears to have mentioned it since 1829, and Taschenberg 

 makes no reference to the type, when looking through Gravenhorst's 

 collection in 1863. 



This species was originally taken at Breslau, in May, and has not been 

 found on the Continent since 1829 ; it was introduced as British by Mar- 

 shall, in his 1870 Catalogus, but I know of no exact records nor does it 

 appear to have been bred. There are, however, two specimens standing 

 under this name in IMarshall's collection in the British Museum, both 

 taken at Groveley Wood, near Salisbury, which look like small and imma- 

 ture S. podagriai, with the metathorax and abdomen piceous, the legs also 

 somewhat paler and less stout, and a total length of 5 mm. 



COLPOMERIA, Holmgren. 

 Holmgr. Ofv. 1859, p. 126 ; Sv. Ak. Handl. 1860, n. 10, p. 44. 



Head smooth and transverse ; clypeus imperfectly discreted, somewhat 

 convex and apically rounded ; mandibles narrow. Antennae slender, 

 short and attenuate. Thorax longer than high ; notauli very distinct 

 w'ith a transverse crista on either side in front ; metathorax a little 

 higher than long with the areola narrow and no apophyses. Scu- 

 tellum normal. Abdomen narrow and smooth ; basal segment nearly 

 parallel-sided, longer than broad and discally bicarinate ; the second and 

 third obliquely impressed anteriorly with a short and distinctly determi- 

 nate rhomboidal space ; terebra short, slender and hardly as long as the 

 basal segment. Legs slender, with the anterior femora subincrassate, 

 subexcised or strongly sinuate from its centre to apex ; anterior tibiae 

 basal ly curved or subarcuate; apical tarsal joint subdilated, its claws large 

 and in 9 basally lobed. Wings with the submarginal nervure very short 

 and no areolet ; nervellus intercepted and antefurcal. 



Holmgren points out that the structure of the front femora will distin- 

 guish this genus from all other Pimplinae ; it is not now quite as he left 

 it, however : he based it entirely upon the femoral conformation and 

 included in it Gravenhorst's Ephialtes inanis, now considered, on account 

 of its complete areolet to be a true Pimpla. Thomson says (O. E. 758) 

 that this genus differs from Polysphincta in the femoral modification and 

 in the mesonotal cristae ; but later [Jib. cit. xii. 1251) he includes it in that 

 genus, considering the distinctions insufficient to warrant generic rank. 

 It appears to me extremely probable that the present genus is synonymous 

 with Scatnbus, Htg. (Jahresb. 1838, p. 267), which is not tabulated by Ash- 

 mead (Proc. U.S. Mus, 1900, p. 152), or differs from it only in the absence 

 of the areolet.

 Head small and narrower than the thorax ; palpi and mouth pale strami- 

 neous. Antennae infuscate-black, a little longer than half the body ; pale
