116 BRITISH ICHNEUMONS. [Pinipla. 



is entirely immaculate ; the mesonotum has sometimes only two red discal 



vittae, as dcscribi'd by Thomson; the sciitellum is occasionally black; and 

 Erischke draws attention to a form of both sexes with entirely black 

 thorax, and the posterior tibiae of the ^ not pale at their base. 



This species, which has hitherto been mixed in Britain with P.ociilatoria 

 and is not recorded hence, is said to occur unconunonly in Sweden and 

 Germany, rarely in Belgium in August, and Brischke tells us he has bred 

 it from Gastiflpacha nmstria in Prussia. ' With us it is certainly commonest 

 in September, when Tuck has sent me three females from Tostock and 

 Finborough Park, in Suffolk, and Butler another from Abinger Hammer, 

 near Dorking; the former has met with a male at Tostock in June and I 

 took an example of the same sex at Horning Ferry, in the Norfolk Broads 

 on the 15th of that month in 1901 ; a second at Finningham in Suffolk on 

 3rd, 1903 ; as well as a female in Wicken Village, in Cambs., at the same 

 time of 3'ear, all by sweeping. Beaumont took it at Malvern at the end 

 of August, 1898.

A slender black species with white inner orbits, scutellum and hind 

 tibiae. Head narrowed behind the large and subprominent eyes ; face 

 subglabrous and narrower than the smooth and shining frons ; palpi, 

 clypeus, in ^ face and in both sexes the internal orbits to the vertex, 

 pale stramineous ; clypeus apically depressed and slightly emarginate. 

 Antennae filiform, much longer than half the body and not apically 

 attenuate, rufescent beneath and in ^ basally paler. Thorax black with 

 only humeral lines and others beneath the radices pale stramineous ; 

 mesonotum strongly nitidulous, extremely finely punctate with fine grey 

 pilosity ; mesosternum in type form more or less broadly red; metathorax 

 sparsely and not very deeply punctate and pilose with weak and parallel 

 lateral areolar costae ; spiracles circular. Scutellum black with its apex, 

 and the po.stscutellum, pale stramineous. Abdomen parallel-sided, slender 

 and cylindrical, somewhat strongly punctate, black throughout ; basal 

 segment hardly longer than broad with its basal excavation alone carinate ; 

 segments apically smooth and distinctly tuberculate laterally ; terebra 

 slender and somewhat shorter than half the abdomen. Legs normal and 

 not stout, red with the anterior of the ^ pale stramineous and coxae of 

 both sexes rarely badious ; hind tibiae white with their apices and a band 

 before the base ferrugineous-nigrescent, their tarsi black with the joints 

 basally white ; 9 with the hind trochanters often infuscate, their tarsal 

 claws very small and basally lobate with the apical joint double length of 

 the penultimate. Wings normal, hyaline, with the stigma jjiceous and 

 and tegulae pale stramineous ; areolet subtriangular and hardly sessile 

 with its outer nervure pellucid at base and apex ; radial nervure externally 

 straight though a little sinuate before the inflexed apex ; nervellus not 

 very strongly postfurcal, intercepting a very little above the centre,
