82 BRITISH ICHNEUMONS. {Pimpla. 



smooth, shining, black with the second sometimes basally infuscate ; 

 terebra black and a little shorter than the body (abdomen 7 mm., terebra 

 nearly 8 mm. — Tasch.), with the valvulae setigerous. Legs normal, 

 flavous-red; tibiae apically and before the base subinfuscate, with the hind 

 ones dull fulvescent beneath and centrally as well as at the base whitish 

 above ; hind coxae red, their tarsi infuscate with the joints basally 

 whitish ; onychii double length of the penultimate joint, claws basally 

 lobate. ^^'ings at least basally tlavescent ; stigma stramineous ; radix and 

 tegulae whitish ; areolet irregular, subsessile ; radial nervure slightly 

 curved towards the apex ; nervellus intercepting very slightly below the 

 centre. Length, \\ — 10^ mm. 



Gravenhorst says this female is intermediate in conformation between 

 P. rohorator and P. didyfiia ; Holmgren gives two \'arieties, one with the 

 coxae infuscate and the hind tarsi mainly testaceous and the other with 

 the hind legs entirely red. 



This species appears to me to be sufficiently distinct from P. nuciim, 

 Ratz., in its uneven, strongly punctate abdomen, the elevated and distinctly 

 nitidulous apices of the segments and in the always more or less flaves- 

 scent wings. 



It is very closely allied to P. punctivtuiris, from which the distinctly 

 bicarinate metanotum will distinguish both sexes and the emarginate 

 femora the $ ; to my new P. gallicola, which differs in the wanting cari- 

 nae of the postpetiole ; and the more I study each author who mentions 

 "/*. calohata, Grav.," the more am 1 convinced that it is a most compound 

 species, including under a single name very numerous quite distinct forms 

 of Hartig's genus Scambus. No doubt can remain that Schmiedeknecht 

 was in error in here including P. puncthentris, whose $ has simple front 

 femora; and most probably P. buoUanae^plauata, brunnt'a,cingulata, cingu- 

 latella and, perhaps, P. lojigivcntris would prove to be perfectly good and 

 distinct species if the types could but be compared infer se. For my own 

 part, I consider P. calo'bata to be a small species of five-and-a-half to seven 

 millimetres, with the abdominal tubercles and segmental apices somewhat 

 distinctlv elevated, the terebra at least three-quarters the length of the 

 abdomen, the basal segment laterally almost glabrous with the central 

 carinae extending far beyond its centre, the metathorax bicarinate and 

 the (5 front femora distinctly emarginate. 



No authentic details of this much confused species are recorded ; it has 

 long stood in our catalogues, but it has not hitherto been at all under- 

 stood in Britain, as is evidenced by the number of hosts given by Bridg- 

 man for P. punctiventris and in the Entom. for P. nuciim ; probably all 

 the latter are referable to the present species. The only published record 

 I can find is that of Parlitt, who professes to have found it in Devonshire 

 in June and July ; his specimens are in the Llxeter Museum. It has 

 occurred to me infrequently and at long intervals : I beat a male irom 

 pine in Bentley Woods early in May, 1895 ; Tuck sent me a female from 

 Aldeburgh in September, 1899 ; I took it at Southwold in July, 1901 ; 

 another at the same time at Gosfield in Essex, in 1902 ; two in Tudden- 

 ham Fen, early in June ; and one by sweeping after dark, in Herringswell 

 Fen, in August, 1905. I possess examples taken from the Deal sandhills 

 by Sladen, at St. Issey in Cornwell by Davies, at Nunton in Wilts and 

 the Isle of Wight by Marshall, at Shere by Capron, at Cadney in Lines, by 

 Thomley, and at Crookston in Scotland in June, by Dalglish. That the 

 male and female are correctly associated I have abundant proof from 

 Banks, who has given me both sexes (referred to at Ichn. Brit. ii. 134)
