154 BRITISH ICHNEUMONS. {Omorga 



and somewhat narrow postpetiole. I took an interesting pair on marram 

 grass by the sea at Hohne in Norfolk on igth August, 1906, which difler 

 from the typical form in their more nitidulous and subfusiform abdomen 

 with apices of its central segments rufescent, in their much better defined 

 and subparallel-sided metanotal areola, extremely obsolete alar areolet, 

 shorter scapal pilosity and small size of only \\ mm.; I propose to term 

 this form var. psatiwiae, nov. 



This species occurs in Italy and Germany in May and June, the female 

 is infrequent in southern Sweden ; it has been noted from Austria ; Schm. 

 says it preys upon Giapholitha ocellana and Giraud in 1877 upon Thal- 

 pochares rosina, probably in France whence Gaulle records it, as does 

 Tosquinet in June and July in Belgium. It has long been known as 

 British and was bred (Entom. 1883, p. 66) from Hyponomeuta phimheUa 

 and Cokophora onostncUa by Elisha; it is very common in Norfolk and 

 has been raised by Fletcher and Atmore from Gelechia instabUella, nota- 

 ttl/a and proximclla, from Phoxopteryx laetaiia, Grapholitha miiiutayia 

 and Lapronia quadj'ipumteUa (Bridg.), to which Bignell adds Butalis 

 gra?idipt'ji7iis on 15th May in Devon. It is very frequently bred by lepi- 

 dopterists, but is by no means common on the wing : Dorking in August 

 (Butler), Oxshott in July (Beaumont), Shere (Capron), Co. Armagh 

 (Johnson); I have met with it at Wroxham and Ranworth Broads in 

 Norfolk, Wilverley in the New Forest and at Parkhurst Forest in I.W., 

 during June; but only in the Reydon Marshes, by sweeping meadow- 

 grass at Bramford and flying at ChaerophvUum temuhim flower at Belstead 

 from 4th June to 6th July, in Suffolk. A female was bred on 26th August 

 from Vanessa Atalanta at Hanwell (Montgomery) ; several bred from 

 Surrey Pychid cases in the middle of June and of September (Sich and 

 Tonge); bred at Romsey in Hants on 8th March, 1884, from Agroiis 

 porphyrea (Buckell); several of both sexes bred from their own very pale, 

 unicolorous stramineous, fluffy, cylindrical cocoons of 5 mm., out of 

 forced Penthina dimidiana at Medge Hall near Doncaster between 14th 

 and 20th February, 1901, and captured there at Ashby on 30th May, 

 1900 (Dr. Cassal); both sexes bred in the Isle of Purbeck on 4th July 

 from Sericoris hifasciana. Haw. {cf. Ichn. Brit. iii. loi); a dozen between 

 nth and 17th August, raised in Isle of Portland from Luffia lapidella, 

 Goeze; and a male bred, along with several Apanfelcs, out of Gekchia 

 salicornuie, Hrng., from Yarmouth in I.W., between 4th and end of 

 August, 1896 (Bankes) ; Mr. H. J. Charbonnier has also sent me a male 

 from Bristol, which he belie\ed had emerged from Sesia tipuliformis, but 

 this seems somewhat uncertain.
