A single German pair ((}rav.), very rare in the middle of luly in Sweden 

 (Holmgr.), bred from Tortrix buoliana by Hartig (lahresb. p. 268) and by 

 Bernuth, as well as from Tinea fcwillaticella fGc/ec/iia dodecclla) by Reissig 

 (Ichn. d. Forst. iii. go), Denmark (Thoms.), Austria (Kirch.) and Belgium 

 during July and August (Tosquinet). It has also been bred on the Con- 

 tinent by Brischke from larvae of a Hypoftometiia — specified as H. awir- 

 jtiellus by Gaulle — and in France from Nothris rcrhascello ((liraud, Ann. 

 Soc. Fr. 1877, p. 403). In Britain it is recorded from Yarmouth in Nor- 

 folk and bred from Cochylis zephyrana and Eupaai/iii atricapilana (Bridg- 

 man) ; captured at Plym Bridge in Devon about the middle of )uly 

 (Bignell); bred from — ? Toiiiix in — Cynips A'o//(in ^a\h (Kntom. 1880, 

 p. 256). I possess but a single pair, bred from Galanthia or Ihitalis 

 varu'/la, Steph., between 15th and 21st June, 189b, by E. R. Bankes, in 

 the Isle of Purbeck in Dorset.

 with the anterior ochraceous ; hind coxae and trochanters black, apically flavidous : their femora 

 ferrugineous or in ? black, wiih apices of the tibiae flavidous, the latter at both extremities an<i 

 apices of iheir tarsi piceous. Wings entirely hyaline, with nervures and stigma infuscate. Length,

Curtis says of it "with the moths {Orthotatnia iRetiiiia) Huoliana) I reared two parasites, one is 

 a /'"!A'!<f.s and the other is a tine species of the family Ichneumonidae. It is allied to Gravenhorst's 

 Creiiiiistus coHy/Hois "- left in the present genus by Thomson and bred from Kctinia Huoliana by 

 Giraud -" but as it does not agree with any of his species I shall describe it." Three males, and as 

 many females, hatched during the fourth week of July, after the moths had ceased to appear.
