Head black, a little narrowed behind the eyes, of $ with piceous pubes- 

 cence; cheeks immaculate; mouth parts ferrugineous, frontal orbits fiavous 

 or red ; $ with palpi, mandibular mark, clypeus, face except rarely its 

 centre, and sometimes a line at the external orbits, flavous ; mandibles 

 bidentate and somewhat slender. Antennae slender, setaceous, black ; of 

 ? white-banded, of $ with scape flavous beneath. Thorax black with 

 lines before and beneath radix flavous ; areola sub-quadrate, costulae 

 obsolete ; apophyses small but distinct. Scutellum flavous, rarely black 

 in $ . Abdomen elongate-oval, black ; segments two and three flavous 

 or fulvous and generally apically black, or with only the basal margin 

 flavidous or red ; six and seven fulvous-margined ; second to fourth ven- 

 tral segments of S plicate, ultimate not spinate ; post-petiole aciculate ; 

 gastrocaeli and thyridii small, sub-obsolete. Legs somewhat slender, black; 

 tibiae, except apices of posterior, flavous ; tarsi usually fulvous ; anterior 

 and often the hind legs of ^ flavidous. Wings a little clouded, stigma 

 fulvous. Length, 12-17 t^^- 



The ? may be known by its sub-triangular head and slender antennae, 

 of which the second flagellar joint is longer than broad ; the (J has the 

 genital valvulae dorsally pale ; and in both sexes the metathoracic spines 

 are small but distinct, the coxal areae obviously discreted and the meta- 

 pleurae sub-rugosely striate. 



This is one of our most variable species, especially in the colour of its 

 scutellum, legs, and abdomen, which last varies from entirely black to 

 fulvous or flavidous with the basal segment only black. Four of these 

 varieties have been described as distinct species : that with the second 

 and third segments red, more or less apically black, the fourth to sixth 

 black with the seventh fulvous, was named A. spoliator, by Wesmael, 

 followed by Marshall ; that with the basal segment only entirely black, 

 two flavous patches on the prothorax, metanotum, and occasionally also 

 on the mesonotum, constituted /. ochraceus and /. laeius of Tischbein ; 

 that with the central segments flavous, apically black, is /. erythropygus^ 

 Grav. ; and the male with these segments red-yellow, margined with 

 brown, and having the hind femora for the most part flavous and the 

 anus rosy, is his /. defensorius. 



A very abundant species throughout Europe, it has rarely been bred 

 and is only known to prey upon Smerintkus ocellatus, Acherontia Alropos 

 and CucuUia verbasci in Britain, where Beaumont has recently raised it
