Omorga] BRITISH ICHNEUMONS. 147 



O. Faunus is one of the commonest species of the genus on the Conti- 

 nent ; Gravenhorst's single female was from Heldstedt at the end of July ; 

 not very frequent in central and southern Sweden (Holmgr.) ; bred from 

 Tortrix pupa in Prussia (l^risch.) ; from Plochcuusa paupdhi in France 

 (Gaulle) ; and found in Belgium during June and July (Tosq.). In 

 Britain it has only been bred from Plutdla pornctella by Elisha (Entom. 

 1883, p. 66); captured at Bickleigh in Devon at the end of August and 

 very commonly in Norfolk. 



The above hosts alone are known and the only bred specimens I 

 possess were raised by Chapman from their own cylindrical black 

 cocoons with central white girdle, the whole covered with a white spun 

 down, 5 mm. in length, out of Dcprcssaria fhapsiella at Taormina in Sicily, 

 during 1905. The perfect insect is, however, abundant in Britain, and 

 I have it from Dover (Elliott), Dorking (Butler), West Runton in 

 Norfolk (Wainwright), Guisbrough in Yorks (Roebuck), Coolmore in 

 Donegal (Johnson), Kilmore in Ireland (Beaumont); Copthorne, Green- 

 ings and "Shere in Surrey, Tostock, Bury St. Edmunds, Felden, Bristol, 

 etc. It occurs throughout the late summer from early July to 27th Sep- 

 tember, when the female rarely comes to light after dark about 7.30 p.m.; 

 it is found by sweeping and on country house windows, but by far the 

 greater number is to be seen upon the flowers ot fennel, angelica, Hera- 

 cleum and more rarely on those of thistles [Cnictis palustris) and white- 

 thorn, sometimes in quite high winds on the top of coast clifts. I have 

 taken a hundred at ShankHn in Isle of Wight, Lymington, Lyndhurst, 

 Brockenhurst, Rhinefields and Hurst Hill in the New Forest, Hunting- 

 field in Kent, Oxshott in Surrey, Kirtling in Camb., Ringstead in Norfolk 

 and all over Suffolk.

Black with the femora and tibiae red, and the posterior femora basally 

 black ; scape pale beneath. Head with the palpi and centre of mandibles 

 testaceous. Thorax with mesopleurae not very closely, though obviously, 

 punctate ; metathorax subexcavate, with strong costae. Abdomen with 

 only the ventral plica dull llavidous ; postpetiole convex and laterally 

 rounded ; second segment hardly longer than broad ; terebra a little 

 longer than half abdomen. Eegs red with coxae, trochanters and base of 

 posterior femora black ; Iiind tibiae apically and their tarsi infuscate. 

 Wings sliglitly clouded, with the stigma piceous llavoiis and tegulae 

 whitish. Length, onini. 



Very similar to (). Phuiiiis and only to be dislinguislu-d by the basally 

 black hind femora, and black anterior coxae and trochanters oi both 

 sexes. 



Gravenhorsl knew a single female from Piedmont, and Thomson both 

 sexes from (Gothland; 1 find no further Continental mention of it. This 

 species was recorded as new to Britain by Bridgman (Entom. 1H84, p. 70) 

 on the strength of a breeding from PJp/iippip/iora xctihihiim by l'"letcher ot 

 Worthing; and it was subsequentiv conlirtned as indigenous by its breeil- 

 ing by the same lepidopterist from l\itopiria fuhana and its capture by 

 Almore at Kings Lynn in Norfolk. Half-a-dozen specimens in my
