British Braconidce. 71 



the posterior areas more rugulose ; abdomen 3' narrow, lanceolate ; 

 of the 2 , elongate ; 1st segment $ half as long again as its apical 

 width, of the J somewhat longer, subattenuated towards the base, 

 elevated in the middle, depressed at the sides, longitudinally 

 striolated, or in the middle almost smooth, the following segments 

 entirely so ; wings nearly hyaline, radius originating somewhat 

 behmd the middle of the fuscous stigma. The colours of the 5 

 are variable, but the varieties above indicated are much rarer than 

 the typical form. 



Very rare in England, but formerly taken by Curtis, 

 and a ? by me in a hedge near Abergavenny. Wesmael 

 had only a single example from Liege. Eeinhard's de- 

 scription is from 7 males and 21 females collected in 

 different parts of Germany. Parasitic on the Continent 

 on Buprestis Berolinensis, Fab., and Astynomus cecliUs, L. 

 Brischke saw six issue, on May 23rd, from a hole in 

 timber made by Astynomus. This longicorn is not yet 

 extinct in Scotland, and the Doryctes may be expected to 

 occur in the Black Wood of Eannoch.
