truncate ; ? with internal orbits ferrugineous ; ^ with palpi, sides of

 fulvous towards the base, at least beneath ; of ? white-banded with the 

 sixth flagellar joint quadrate. Thorax black with a flavous line beneath 

 the radix ; ^ also has the pronotum and sometimes a line before the 

 radix, flavous ; areola sub-quadrate, of S transverse ; coslulae obsolete ; 

 apophyses very minute. Scutellum stramineous. Abdomen acuminate- 

 oval, at least in S ', black, with the second and third segments, except 

 their incisures, red; fourth to seventh apically white-margined ; post-petiole 

 aciculate ; gastrocaeli small; ventral segments two and three alone plicate, 

 the ultimate of ^ elongately acuminate ; genital valvulae black. Legs

 tibiae and tarsi, black. Wings a little clouded ; of <? flavescent with pale 

 tegulae; stigma red; areolet pentagonal, strongly narrowed above. Length, 

 1 2-16 mm. 



At once known from the last five species by its centrally red abdomen. 



This is a very widely distributed species throughout Europe, and it has 

 been bred from Agrotis segetuin and Triphaeua pronuha. Parfitt found 

 it upon umbelliferous flowers, on the borders of woods, during July, in 

 Devonshire ; it is also recorded by Bridgman, from Norfolk, by Bairstow, 

 from Goole, in 1879, and by Stephens as scarce, near London, in June, and 

 in the British Museum is an example under this name labelled " Suffolk." 

 I have seen a fine male, captured by Luff, at St. Ouen Bay, in Jersey, early 

 in August ; the female hibernates and is to be met with in September and 

 late in August, when I have found it upon flowers of cultivated carrot, at 

 Tuddenham St, Mary, in Suff'olk.
