Porizon] BRITISH ICHNEUMONS. 33 



The J is very like P. harptirus, but the petiole is shorter, the lueta- 

 thorax much more finely punctate and the petiolar area shorter. 



Occurs from Lapland to France. Ratzeburg tells us that Bouch6 bred 

 a female in Germany, which he considered to belong to this species, from 

 Cvnips Quoxiis folii ( Dryophanta fuUi ; D.sciitcllaris, Entom. 1880, p. 257); 

 it is found in Belgium during July and August. Very uncommon with 

 us, and I can find no records published; 1 possess four females and a 

 male from Surrey : Shere (Capron), Abinger Hammer at the end of 

 August, igoo (Butler), and Reigate in July, 1872 (Saunders); to which 

 county I should have considered it nearly restricted with us were it not 

 that Col. Yerbury has given me a single female, taken by him on 17th July, 

 1904, at Nairn in Scotland.

Head finely and sparsely punctate, somewhat nitidulous, little narrowed 

 posteriorly with vertex narrow and posteriorly subemarginate ; frons of 9 

 shining and of ^ somewhat dull; eyes elongate and not very prominent; 

 temples and the rather short cheeks smooth and shining; clypeus deplan- 

 ate and nitidulous, its apex together with palpi and centre of mandibles 

 rufescent. Antennae slender and basally ferrugineous; flagellum filiform 

 with distinctly discreted joints, of which the basal is almost longer than 

 scape. Thorax cylindrical and stouter in (^ ; mesonotum dull and finely 

 pubescent with notauli apically visible ; melalhorax rugosely punctate, 

 rougher in (J ; basal area elongate and rectangular, petiolar area entire. 

 Scutellum laterally margined. Abdomen usually rufescent or ferrugineous 

 from second segment, anus generally infuscate or very rarely the abdomen 

 is nearly entirely black above ; of 9 elongate fusiform and subcompressed, 

 of J strongly compressed ; basal segment linear with postpetiole of ^ 

 twice as long as apically broad, of 9 only half as long again; second 

 segment twice longer than broad, with thyridii elongate ; apical segments 

 discally incised; terebra slender reflexed and shorter than first segment. 

 Legs somewhat stout and red with coxae infuscate or black ; hind tibiae 

 longer than their metatarsi, and their femora often infuscate. Wings 

 slightly clouded and a little narrow; stigma nigrescent and of normal 

 size ; tegulae flavidous or rufescent ; radius apically straight. Length, 

 4-7 mm. 



This is the commonest species of Porizon in Europe and extends pretty 

 well over the whole Continent. It does not, however, appear to have been 

 there bred since Ratz. {/of. ci/.) recorded it from the galls of Rhodihs rosac 

 in Germany; considering the numbers ot Orthvpdma luliolator that have 

 been raised from these bedeguar galls both here and abroad, it is remark- 

 able that we, like Schm., have failed to raise this species. Lastingham in 

 Yorks. (Marshall), Eaton near Norwich (Bridgman), Bolt Head in Devon 

 at the end of June (Bignell). In my experience this is an abundant 

 species throughout eastern and southern England, occurring in profusion
