Trematopygus | BRITISH ICHNEUMONS. 175 

mesopleurae punctate and shining; metanotum not smooth, areola and 
petiolar area confluent and strongly carinate, basal area subquadrate, cos- 
tulae strong. Scutellum black. Abdomen oblong-ovate, black with the 
second and third segments red, usually discally or mainly black; basal 
segment gradually explanate throughout and not half as long again as 
the breadth of its aciculate apex, strongly sulcate and bicarinate to centre 
of postpetiole ; terebra reflexed, not exserted. Legs fulvous and not 
slender with coxae, base of trochanters, hind tarsi, apices of their femora 
and apical third of their pure white tibiae, black; hind calcaria, and @ 
anterior coxae and trochanters entirely, stramineous. Wings ample and 
hyaline, radix and tegulae stramineous, stigma pale piceous and some- 
what broad; areolet small and petiolate, with outer nervure curved; 
nervellus slightly antefurcal, intercepted at its lower third. Length, 
43—73 mm. 
This species must be much rarer on the Continent than in Britain, for 
it was not adequately described nor the ¢ known till Pfankuch examined 
the type 9 in 1906 and he says that the species noticed under this name 
by Kriechbaumer (Ent. Nachr. 1897, p. 186) is distinct. 
It is only recorded from Breslau, France and Prussia, where Brischke 
bred it in 1878 from larvae of ematus aethiops. Stephens took this 
species and Desvignes correctly named his own four examples; Marshall 
found it at Nunton in Wilts, Bugbrooke in Northants, Cornworthy in 
Devon and Botusfleming in Cornwall; it occurred to Bridgman at Earl- 
ham, near Norwich, in July, and to Parfitt by sweeping among grass and 
clover in May in Devon. I possess it from Blackheath in June, 1899 
(Beaumont), captured at Brockenhurst on znd June, 1910 (Lyle); Scotton 
Common in Lincs. (Thornley), Felden in Herts (Piffard), Benacre Broad 
in Suffolk at the end of August, 1900 (Tuck), and have found it at the 
beginning of June by sweeping in Wicken Fen in Cambs., in July in 
Beaufort Park near Hastings, early in August in a Lyndhurst greenhouse 
and in the middle of September at Foxhall near Ipswich on the flowers of 
Angelica sylvestris in marshes.
