British Braconidcc. 117 



Somewhat variable. Prothorax usually testaceous, the neck 

 blackish, seldom entirely pale ; sometimes black at the sides, and 

 margined above with rufous. Disk of the mesothorax from black 

 passing into piceous and testaceous ; scutellum, pleurae, and pectus 

 rufo-testaceous. Metathorax black, but with a more or less rufous 

 triangular patch above the hind coxae, sometimes overspreading 

 the whole disk except the middle. Segment 2 paler than the 

 pleurae ; the following segments seldom concolorous, usually more 

 or less blackened, especially in the $ . Belly rufo-testaceous or 

 piceous, in various shades. Head rather narrower than the thorax ; 

 face flat, quadrate ; clypeus convex. Antennas ? as long as the 

 body, subsetaceous, 33 — 35-jointed ; of the $ much longer, also 

 subsetaceous, 35-jointed; entirely fuscous, or the 2 basal joints in 

 the $ and more in the $ are testaceous underneath. Farrow of 

 the mesopleurae shining, smooth, finely crenulate at the base. 

 Metathorax not very convex, finely reticulato-rugose, with a medial 

 carina. First abdominal segment regularly striolated, more than 

 \ of the abdomen in length, gradually widened from the post- 

 medial tubercles to the apex, which is 3 times broader than the 

 base ; tracheal grooves comparatively minute. The stigma is 

 sometimes infuscated on its inner margin, and rarely altogether of 

 a darker colour; the recurrent nervure is usually interstitial, but 

 sometimes deviates slightly to one side or the other. 



Described from seven females, four males. Common. 

 In Fitch's collection are a $ ? bred by him and Bignell 

 from Tceniocampa stabilis, View. Bignell and Hellins 

 bred it from Scopelosoma satellitia, L. ; and Bignell 

 others from Noctua triangulum, Hufn., Calymnia trape- 

 zius, L., and Ocneria dispar, L. ; the last-mentioned 

 larva was from Switzerland. Cocoon pensile, exactly 

 like that of pulchricornis and ictericus, only larger.
