A large, robust species. Head black ; that of $ small, with palpi, man- 

 dibles, clypeus and face pale flavous ; the apical margin of clypeus slightly 

 dei)ressed and emarginate. Antennae black ; $ white -banded, with the 

 first joint thrice longer than broad, and the eighth quadrate ; of $ with 

 scape flavous beneath, the fifth and following joints of flagellum carinate. 

 Thorax broader than- head, black ; that of $, with the pronotum, and a 

 callosity before the radix flavous ; metathorax bidendate, with five upper 

 areae, of which the areola is coarsely rugose, sub-quadrate, with apex 

 emarginate ; that of $ transverse and broadly rounded at the base. Scu- 

 tellum obtuse, strongly convex, stramineous. Abdomen black ; of $ stout 

 and broad, with segments, two three, often also apex of first and part of 

 fourth, red, five to seven broadly, and four rarely narrowly, white-marked ; 

 of c^ lanceolate, with segments two to four, apex of first, and sometimes 

 part of five, flavous, or tw^o to four red-yellow, dorsally black-marked, seven 

 with a longitudinal white line, the third transverse and the incisures rufes- 

 cent ; post-petiole aciculate or somewhat rugose, gastrocaeli rather large 

 and deep ; the intervening space sub-rugose. Legs flavous, trochanters 

 and co.xae in part, ? with the femora and apex of hind tibiae, $ usually 

 with apex of hind femora and tibiae, infuscate or black. Wings slightly 

 clouded ; stigma fulvous, tegulae whitish or flavous. Length, 20-22 mm. 



One $, which I took upon Angelica sylvestris, at Barnby Broad, in 

 Suffolk, at the end of August, 1898, has the posterior coxae only narrowly 

 black within, and all the femora, tibiae and tarsi entirely flavous. 



Stephens says the females are rather common around London, about 

 Hertford, &c., but that he had only seen one male, which was taken in 

 a Hertford garden, at the end of May ; Hope found the female at Netley, 

 and Forster says it is rare, in hedges, in England. Bignell has bred it, in 

 June, from Triphaena fimbria ; and Thouless has taken the female at 

 Mousehold Heath, in Norfolk (this specimen, labelled September 5th, 

 1883, is in the Bridgman collection, with another from Chatteris, 1882) ; 

 in the British Museum is an example labelled " Bantham, August " ; it is 

 also recorded from Essex. 



The forewing is figured in " Knowledge " V. p. 245 ; Thomson appears 

 to be in error in ascribing /. grossorius to Linnaeus. It has a wide distri- 

 bution throughout northern and central Europe, extending to Russia, and 

 is found among undergrowth in w^oods and gardens.
