British Braconidat. 233 



The smallest species ; some German specimens, accord- 

 ing to Paitlie, being only | lin. long. It most resembles 

 dolens, but differs both from that and tristis in the colour 

 of the wings, which are very slightly tinted, and by 

 Haliday described as pale ferruginous. The decolorous 

 line which crosses the wing is hardly perceptible. The 

 sides of segments 1—2 are narrowly dull testaceous. 



Euthe possessed 20 males and 36 females, taken 

 between May and June in the neighbourhood of Berlin ; 

 Haliday only one ? , and he says that it is very rare in 

 the north of Ireland. I captured formerly about a dozen 

 in Leicestershire ; more recently a male near Aberga- 

 venny, and two females in Northamptonshire. Fitch 

 has bred a ? at Maldon from an undetermined larva ; 

 in Bridgman's collection are four males and six females 

 reared by Norgate from Trichiosoma hetideti, Kl. ; these 

 are a trifle larger than other specimens. Bred by Dor- 

 ville from Diantha'cia capsincola, Hiib., one ? and four 

 cocoons on a card. The cocoons are indistinguishable 

 from those of tristis, Nees. According to Brischke bred 

 from EiqntJiecia succenturiata, L., and exiguata, Hiib. ; 

 but as he says the cocoons are like those of M. tiiherculi- 

 fera, Wesm., there is probably some error.
