226 BRITISH ICHNEUMONS. 



gastrocaeli, the more broadly-margined segments, the croceous legs, and 

 more profusely pale-marked head and thorax. 



Here again we meet with the marvellous powers of concise description 

 possessed by Haliday. In a very few words he describes at an early date 

 a species which, I think, can be nothing but that here conjoined with it. 

 Though the types are probably still extant in the Dublin Museum of 

 Science and Art, the Director informs me he cannot indicate them, since 

 no labels are affixed, and it reflects the more credit on the author that 

 types are not necessary to the synonymy of his species. I am indebted 

 to Rev. T. A. Marshall for calling my attention to the similarity between 

 Haliday's and Wesmael's descriptions. 



Observers have naturally hesitated to record their captures on the au- 

 thority of Haliday's short description, and we consequently find only the 

 original mention of this species in Britain, " Ireland, on a willow, in 

 September" ; I took several of both sexes upon Salix repens, \SiX. fusca, in 

 Tuddenham Fen, at the end of August, and there is, I believe, a specimen 

 in the British Museum labelled " F. Bond ; I. of Wight." On the Con- 

 tinent, F. leucogrammiis has been found in Sweden, Holstein, Hungary and 

 Russia, but has not yet been bred. 



6. variegatus, Wesm. 



Platylabtis variegaftis,\^^e?,m. Nouv. M6m. Ac. Brux. 1844, p. 156, $ ; cf. Bui. Ac. 

 Brux. 1853, p. 322; Holmgr. Ichn. Suec. ii. 310; Thorns. O. E. xix. 2107 ; Berth.

Head black, strongly narrowed behind the eyes ; cheeks sub-buccate ; 

 frons alutaceously punctulate, centrally obsoletely canaliculate ; angles of 

 the convex, closely and distinctly punctate clypeus somewhat obtuse ; $ 

 with facial and frontal orbits flavous. Antennae slender, white-banded in 

 both sexes ; scape of $ occasionally rufescent beneath. Thorax dull, 

 black ; pronotum, callosities before and beneath radix, and two dots in the 

 petiolar area, stramineous ; areola transverse ; costulae sub-entire ; coxal 

 areae distinctly discreted ; apophyses somewhat long and acute ; spiracles 

 elongate. Scutellum and post-scutellum flavidous. Abdomen black, with 

 all the segments apically white-margined and the seventh entirely white ; 

 post-petiole rugose, apically rectangular ; gastrocaeli large and deep, with 

 the intervening space narrower than the centre of post-petiole and often 

 striate ; remaining segments smoother ; terebra hardly exserted ; $, geni- 

 talia stout. Legs red ; coxae, trochanters, hind tarsi, apices of their some- 

 what arcuate tibiae, and sometimes of their femora, black. Wings hyaline, 

 stigma testaceo-piceous ; areolet deltoid, sub-coalesced above. Length, 

 9-10 mm. 



On the Continent this species appears to be of somewhat rare occur- 

 rence, being found only in Belgium and Sweden. It was first recorded 

 from Britain in Marshall's 1870 catalogue, but I know of no records.
