 fluent fenestrae and superficial gastrocaeli. But it cannot be united with 

 the riatylabi, since the hind tibiae are not curved and arc, like the front 

 ones, spinulose."

Head dull black ; face a little prominent, short, and roughly punctate ; 

 two vertical dots, and sometimes others at the external orbits, white. An- 

 tennae black, somewhat compresso-dilated ; scape strongly pilose ; of ? 

 white-banded with the tenth flagellar joint quadrate. Thorax somewhat 

 shining, black, of ? rarely with a line beneath the radix white ; meta- 

 thoracic areae sub-obsolete ; apophyses distinct but short. Scutellum, at 

 least apically, flavous ; post-scutellum of $ also sometimes pale. Abdomen 

 black ; of $ somewhat nitidulous with segments two, three, sides of four, 

 and sometimes apex of the first, red ; of $ entirely black with the three 

 basal segments finely rugose and dull ; post-petiole finely rugose and dull 

 throughout. Legs black, with the front tibiae in part and tarsi of $ , all 

 the femora, tibiae and, except the hind ones, tarsi of $ , red. Wings with 

 stigma piceous ; areolet deltoid, the sides strongly converging or coalesced 

 above; tegulaepiceous, of (^sometimes flavous-marked. Length, 13-15 mm. 



This species, which is common on the Continent, where the female is 

 known to hibernate, is undoubtedly widely distributed in Britain, and 

 nearly all the local lists include it. It has been bred from Hadena adiista, 

 Abrostola Iripiasia, and, in south Devon, from Taeniocampa slabilis, in the 

 middle of August ; there are records of its occurrence in south Whales ; 

 near London, in June and July ; Bickleigh, in Devon, in September ; 

 Land's End; not uncommonly in Norfolk; Essex; and at Hastings, 

 where it has been several times captured by Mr. AV. W. Esam. Adams 

 has taken it in his fly-trap, at Lyndhurst, Hants., in the middle of August ; 

 Thornley, at South Leverton and Cadney, in September; and Tuck, both 

 sexes, near Bury St. Edmunds.
