segment reddish-brown, with a yellowish line in the 

 middle ; beneath, the yellow margins are broader, and 

 there is also a sub-lateral yellow line. In the $ the 

 penultimate segment is truncated, the sides very oblique 

 and excavated ; beneath, on each side of the ventral 

 fissure is inserted a long and narrow piece, greenish- 

 yellow, ending in an intensely black anvil-shaped 

 crotchet, the arms being produced and curved, but in 

 opposite directions ; the penis is very long, obtuse, oval, 

 deeply canaliculated beneath, yellow, the side-margins 

 thickened, and intensely black ; at its extreme base, in- 

 ternally, are two short testaceous crotchets, turned out- 

 wards, and curved ; terminal segment above small, the mar- 

 gins rounded and finely fringed, yellow. In the ? the 

 last ventral segment is broad, strongly rounded, yellow. 



Legs yellow ; intermediate and posterior femora with 

 an indistinct broad fuscous ring before the apex. 



Wings long and narrow, the costal margin slightly 

 rounded to the junction of the sub-costa; pterostigma 

 narrow, pale yellowish brown, with one transverse vein- 

 let, the inner edge placed near the middle of the penta- 

 gonal areole below it, the outer edge extending- far beyond 

 that areole ; the Jirst apical vein is simple, curved, and 

 starts out of the base of the outer margin of the ptero- 

 stigma (PL IX. fig. 2, indicated at a); suh-costa ending 

 before the pterostigma ; 7-8 costal veinlets ; three dis- 

 coidal areoles ; second apical vein (counting the simple 

 vein proceeding from the pterostigma as the first) tri- or 

 quadri-furcate, third simple, fourth, fifth, and sixth once 

 forked ; neuration blackish, the costa at the base, the first 

 one or two costal veinlets, and the radius for the greater 

 part of its length, yellowish. 



Expanse of wings, $ , 8-9 lines; ? , 9-11 lines. 



I have seen but one living specimen of this insect, sent 

 to me by Mr. Barrett of Haslemere. It occurs chiefly in 

 the south of England, but Mr. Hislop has sent me an ex- 

 ample taken in Morayshire in the north-east of Scotland, 

 which scarcely difiers from southern individuals. It may 

 be recognized by the extent of the red markings on the 

 head, by the position of the pterostigma with respect to 

 the cellule below it, and especially by the first apical vein 

 being simple, and starting directly from the pterostigma. 

 The only other species which constantly possesses this 

 character is B. bcetica, Rambur, which is to be separated 

 by the shorter and broader head, &c. ; but this must not
