68 BRITISH ICHNEUMONS. [Pimpla. 



basally. Wings flavescent with stigma fulvous or flavidous ; radix and 

 tegulae fla\ous ; areolet transverse, not broad, with the outer nervure 

 mainly pellucid ; ner\'ellus subopposite and intercepting in or only very 

 slightlv below the centre. Length, q-ii mm. 



That the above $ is synonymous with lluronia laevigola I can hardl\' 

 credit, since the metathoracic spiracles of that species are described as 

 oval ; in any case it is very closely allied. Bridgman's descri])tion has 

 hitherto been overlooked on the Continent, where the ^ is still unknown. 

 He savs that "it would almost apj)ear that the J is a TInronia and the 9 ^ 

 Pimpla, thus uniting the two genera. I thought at one time it might be a 

 \ariety of Theronia, but such is not the case. Mr. E. A. Fitch kindly sent 

 me a Thenmia from Kaltenbach's collection, and they are very different: in 

 the hind wing of Thenmia the transverse anal nervure is placed behind the 

 brachial fork, and divided distinctly above the middle, whilst the ^ and 

 9 of P. dihita have it opposite the brachial fork and divided almost in 

 the middle or a trifle below." Schmiedeknecht says that (iravenhorst 

 described the present species among his varieties of P. giamincllae, but this 

 can hardly be the case since all of them have the sixth segment black. 



Bridgman first took it in 1877, introduced it as British in 1879, and says 

 in June he took two or three females at Bmndall, near Norwich, and within 

 three or four vards of the same spot the above described males ; I possess 

 a specimen of each sex given by him to Dr. Capron. Ratzeburg origin- 

 ally bred it from Tortrix lesinana in Germany and in Britain Barrett has 

 bred it from Pyrameis cardui (Entom. 1880, p. 68 et 1881, p. 141). It is 

 certainly a ver}- rare species wdth us and I have seen, besides the above, 

 but two females, which were beaten from yew trees in a fir wood at Bent- 

 lev on 20th ^larch, 1903, bv Mr. Ernest Elliott and myself; I had worked 

 the same wood for ten vears and never seen it before.

A slender and badious species, with large abdomen and dilated tarsi. 

 Head black, short, transverse, finely ])unctate, shining and not narrowed 

 behind the internallv deeplv emarginate eyes ; frons unequally impressed, 

 clypeus subdepressed and apically truncate ; palpi stramineous or testa- 

 ceous, face in both sexes immaculate. Antennae filiform, longer than 

 half the body, pale ferrugineous with the apices of the flagellar joints and 

 whole scape black ; scaj)e externally deeply excised. Thorax stout, gib- 

 bous with the metathorax fuhidous ; pleurae punctulate ; metanotum with 

 the areola distinct though apicallv incomplete, and spiracles circular. 

 .Scutellum black with the postscutellum fuhidous. Abdomen as broad as 

 and double length of the thorax, of 9 subcylindrical or oblong-fusiform 

 and a little constricted towards base and apex, of J subparallel -sided ; 

 fulvous with the segments apically elevated ; second to fifth laterally trans- 

 versely impressed, uneven and coarsely punctate ; basal segment distinctly 

 carinate, of J not double length of breadth ; terebra black, one quarter 

 length of abdomen with the \'alvulae shortly pilose. Legs normal, fulvous 

 with the posterior tarsi apically black, their claws distinctly dentate 

 basallv, and the apical tarsal joint in both sexes fully four times longer
