A dull, closely punctate and mainly red female, with elongate lerebra. 

 Head black and not narrowed behind the eyes; face centrally subelevated 

 longitudinally, finely and not very closely punctate with sparse pilosity ; 

 frons and vertex not uneven, distinctly and somewhat clos(;ly punctate 

 with short grey hairs and no central canaliculation ; palpi dull stramine- 

 ous, clypeus badious. Antennae shorter than the body, black, pilose, 

 filiform throughout with the joints not elongate ; flagellar joints cylindri- 

 cal and not apically clavate, second and third subequa! and one-fourth 

 shorter than the basal. Thorax gibbulous, discally deplanate ; prothorax 

 black and shining with sparse white hairs ; the dull, closely punctate and 

 shortly pilose mesonotum and mesopleurae, with sometimes a mark on 

 the metapleurae, red or castaneous ; notauli distinct and subconfluent dis- 

 cally ; metathorax strongly and rugosely punctate and elongately pilose 

 with very faint traces of the areola basally; petiolar region smoother, 

 spiracles small and quite circular. Scutellum and postscutellum dull, 

 closely punctate, red or castaneous, with a basal black dot before the 

 former. Abdomen closely and subconfluently punctate with short white 

 pubescence throughout, as broad as and double length ui the thorax, 

 slightly constricted towards base and apex ; basal segment black, not 

 longer than broad, laterally margined and scabrously pimctate, basally 

 excavate and carinate to centre, apical margin centrally elevated and red ; 

 segments apically smoother but not elevated, castaneous with their ex- 

 treme apices black and their bases centralis' infuscate, the anus entirely 

 red ; terebra exactly as long as the body, black, thinly pilose, transacicu- 

 late with red spicula. Legs fulvous with the anterior trochanters stramin- 

 eous ; posterior tarsi, and sometimes also the hind tibiae externally and 

 basally, infuscate ; claws small, black, simple and not basally lobate ; 

 hind onychii hardly thrice the length of the penultimate joint. ^^'ings 

 hyaline w^ith the stigma entirely pale testaceous, radius infuscate, radix 

 and tegulae whitish ; areolet irregular and subsessile ; nervellus intercept- 

 ing exactly in the centre. Length, 6 — 9 mm. 



Gravenhorst says it is similar in conformation to P. ruboia/or, but more 

 slender with the terebra longer ; it is certainly very like P. pomorum, 

 though larger with the antennae and terebra longer, and the areola not 

 glabrous. 



Marshall followed Desvignes' synonomy of P. i^ariigia with this species 

 and it is very probably correct, although Schmiedeknecht queries its 

 identity with P. ctnopithaus, Costa, w hich appears to differ solely in its 

 appendiculate and longer tarsal claws. This species was introduced as 

 British by Desvignes (Ll.ALAL 1868, p. 174) on the strength of specimens 

 now in the British Museum, reared by Barrett from Toririx buoliana. 

 Ratzburg bred his species from the same host, as well as from Toririx 

 Nordliugcria7ia and T. Mtilsaniiana ; and (iiraud (Ann. Soc. Fr. 1877, 

 p. 410) instances Graplioliiha iripiinciana, Rtiinia Bnoliaiia, Cynips icrri- 

 coia and a species oi Audricus. With us it is recorded from the Lands 

 End district, by Marquand; as bred on ist November from Rctinia trsi- 

 natia and captured at Clearbrook, in Devon, by Bignell ; Adkin bred two 

 females from Reiinia pinivorana, Zell., at Forres (Proc. S. Lond. Soc.
