Pimpla.] BRITISH ICHNEUMONS. 91 



The only hitherto known specimens are five females recorded by 

 Tschek from Austria, which he says measured 8.75-1 1 mm. in length. 

 I have drawn the above description from two females and one male ; the 

 male was bred by Watcrston at Edinburgh in the middle of June, 1899, 

 from a chrysalis of Melanippc flucluata and is in my collection ; one female 

 was captured by Elliott at Birnam on ist August, 1901, and the second 

 was bred by Bankes at Ashford in Kent, early in July, 1901, from a larA'a of 

 Mompha [Laverna) coniurhatdla, Hb. and had apparently itself, spun a white 

 papyraceous cocoon inside a leaf, which contained but the merest debris, 

 probably of tlie host, from which the imago had emerged through an almost 

 square, small hole near one extremity. This species has not been noticed 

 in Britain before, and would appear to be, as in central Europe, rare with 

 us, though from the above localities it must be wide spread. There is a 

 single female in the British Museum, with no name (referred to by me. 

 Trans. Ent. Soc. 1907, p. 45), which I have little hesitation in ascribing to 

 this species, though it is certainly atypical ; it is labelled " Ichneumon 

 oi Lixiis angustatus, Fairlight, Aug. 31st; F.Smith." This is the only 

 known parasite of Z. algiriis, Linn.
