A large testaceous species witli no black markings, very like the O. 

 lu/ius group but with the radius bisinuate (first deflexed, then reflexed) 

 below the linear stigma and above a glabrous area, nervelet wanting, 

 nervellus antefurcal and intercepted far below its centre, head posteriorly 

 buccate, scutelluni strongly carinate to apex on either side, the meta- 

 thorax strongly transcostate and declived from basal transcarina, and the 

 postpetiole nodose. Antennae about length of body, of ^ 66- and of 9 

 63-jointed. Length, 23-30 mm. 



I consider Gaulle quite correct in confirming Brischke's queried syn- 

 onymy of Ratzeburg's species here; Vollenhoven's figure shows the radius 

 slighth' less sinuate than in the type, not an uncommon British form, but 

 I fail lo liiul in anv the minute corneous dot introduced in his plate of 

 1870. A single 9 was originally bred by Graflf from a cocoon of (7^j/rfl- 

 paclia liiiicsfris and later Brischke raised it from larvae of the same moth. 



This species is conmion neither here nor upon the Continent. Ger- 

 manv, Piedmont and a female bred from larva of BoinbvA- /n/o/it {Griiv^; 

 Sweden, a single pair of only six lines in length (Holmgr.); France 

 (Gaulle); Belgium in June, July and August (Tosquinct) ; Branuelas in 

 Julv, 1906, by Dr. Chapman (in coll. Morley); Jerusalem (Schm.). I find 

 no localised records, and the single example in Bridgman's collection has 

 strongly flavescent wings. It a|)pears vc^-v rare and most of my specimens 

 were bred; but two, taken at Bonhill by .Malloch and at Glenmallon in 

 iJ<97 bv Dalglish, seem to have been taken in the field. Waterston 

 raised a female of the maximum size from Hoiiibvx ijutirus in Scotland on 

 17th lime, 1899, the cocoon of its host is 30 mm. in length and its own, 

 placed somewhat oblquely within it in order to leave room for the empty 

 host-larva skin which is pushed to the inner extremity, is 25 nun. in 

 length ; Peachell raised a female from the same host at Weymouth on 

 20th March, 1901 (probably "forced"); South gave me a male from 

 0(i(iiH's/is po/atoiia near London in 1902; and Clutten sent me a pair from 

 Barmouth Bomby~\ callunac in 1906. 



Abroad it is recorded from Chaerocampa ilpenor and a species of Maciv- 

 glossa ((iaulle), Bovihyx hifolii, catax, rubi\ a'cria and i]uiicus (Giraud, 

 Ann. Soc. Fr. 1877, etc.), /A (jucrcus var. spartii (Bellier de la Chavignerie) 

 and Lasiocompa IrcmuUfoIia, Hbn., (Mocsary). Taschi'nberg must have 

 mixed this with one (^f the North American species in recording it (Zeits. 

 Ges. Xat. 1875, p. +30) from Sainia caivpia ; and Marrach's observation 

 of two specimens emerging from a single ])upa of the small Taeuitnowpa 

 gothica (doubly (jueried by Ikidg. -Fitch, Kntom. 188+) is absurd, for it 

 never emertres from its host's c/irysa/is at all.
