150 BRITISH ICHNEUMONS. \_Omorga 



Brischke, and has not again been found on the Continent. It was first 

 taken with us by Dr, Capron at Shere and sent to Bridgman, but is not 

 now in the former's collection, Bignell subsequently found it on ist 

 August at Oreston Quarry in Devon, and de la Garde has given me a 9 

 he took in July, 1895, at Devonport.

Black with the postpetiole subcircular, the anterior legs nearly entirely 

 red, the hind ones white and black marked. Head large, buccate and 

 not posteriorly constricted, with mandibles except apically and palpi 

 whitish. Antennae with the scape rarely whitish beneath. IMetathor- 

 acic areae distinct, with areola not transverse, and lateral areae discreted. 

 Abdomen black with only ventral plica stramineous ; basal segment 

 somewhat shorter than coxae and trochanters, with postpetiole convex 

 and laterally rounded ; second segment a third longer than its apical 

 breadth ; terebra half length of abdomen. Legs with anterior femora 

 and tibiae rufescent ; hind legs and base of intermediate femora black ; 

 anterior trochanters, hind trochanterelli, with centre and extreme base of 

 hind tibiae, white ; metatarsus basally pale. Wings with stigma piceous 

 and tegulae stramineous. Length, 4-5 mm. 



A small species known by the front femora entirely, the intermediate 

 except a basal black mark and their tibiae, fulvous; coxae black; anterior 

 trochanters, hind trochanterelli with a basal band and centre broadly of 

 their tibiae white ; terebra half length of abdomen and the second seg- 

 ment not short. 



Lapland and Sweden in July and August (Holmgr.), Prussia (Brisch.), 

 Austria (Tschek), Belgium in July and August (Tosq.); bred in France 

 from Tischeria complamlla (Ciaulle), and by Dr. Kreichbaumer from Psyche 

 (Aptero7ia) Helix, Sieb. (Thomson). The only record I can find is 

 "Captured at Yelverton, 4th August" (Bignell, 1898, p. 492). It is a 

 very distinct species in its black abdomen and hind femora, with their 

 centrally dead white, not at all flavidous, hind tibiae and is locally very 

 abundant with us. 1 have a hundred and fifty specimens. It is a spring 

 and autumn species in my experience, occurring from April to 19th fune, 

 and from 9th August to 23rd September; at first it is to be beaten from 

 thick spruce hedges, where perhaps it hibernates, and later found on 

 umbelliferous flowers and by promiscuous sweeping ; 1 possess it from 

 Chatham in April, ICS92 (Garde), Irvine INIoor near Glasgow (Ualglish), 

 Finborough Park and Bungay (Tuck), Shere (Capron), and Lyndhurst 

 (Adams). I have found it in Suffolk at Burgh Castle, Bentley Woods, 

 Tuddenham Fen, P'lveden, on the banks of the Orwell at Ipswich in 

 1897, and abundantly on fennel flowers at vYlderton and reeds about 

 Southwold ; elsewhere at Mablethorpe and Market Kasen in Lines., 

 Matley Bog in the New Forest and Clare Island on the west of Ireland. 

 Bankes has bred one batch containing nine of both sexes between 13th 

 and 28th June from Colcopliora pyrrhulipcnndla^ Fisch., and another batch 

 of about fifty, along w ith Pezomachi of both sexes and some small Pimpla
