298 BRITISH ICHNEUMONS. [ Polyblastus 
from Brundall by Bridgman; I have it from Surrey (Capron) and Tostock 
in Suffolk (Tuck). It is by no means common, though I took several at 
Peterborough by the Nene in June, 1908, and have swept it during the 
same month in Tuddenham Fen, at Claydon on 14th September, and 
taken it on carrot flowers at Eye and those of Heracleum at Rishangles in 
Suffolk, late in August. The four specimens named Zryphon ( Tremato- 
pygus) procurator by Stephens in Mus. Brit., upon which that name has 
hitherto figured in our lists, are referable to the present species.

Somewhat shining and black with the mouth, abdomen except basally, 
and most of the legs, red. Clypeus red, subconvex and apically rounded. 
Antennae somewhat shorter than the body, infuscate and at least in g 
rufescent beneath. Metathorax with three distinct areae. Scutellum dis- 
cally deplanate, laterally margined to its centre, and not pyramidal. Basal 
segment black, somewhat short, finely rugose and dilated towards its 
apex, with carinae extending to its centre; remainder of abdomen en- 
tirely red. Legs normal, red with (form typ.) coxae and trochanters 
except apices of latter, intermediate femora externally towards their base, 
and the hind ones broadly in the centre, black or (var. propinguus) the 
posterior coxae partly, hind trochanters dotted with, and their femora 
entirely, with hind tarsi and apices of their tibiae, black. Areolet irregu- 
larly petiolate or subsessile; radial nervure slightly curved apically ; 
nervellus intercepted below its centre. Length, 4—6 mm. 
It appears of little use attempting to regard Z7yphon propinquus, as dis- 
tinct from Z7ryphon pratensis, Gray. Gravenhorst in erecting it thought 
them so similar that he queried both as varieties of Weleges proditor ; and 
Pfankuch, examining the types in 1906, tells us that Z. propinguus differs 
from Z. pratensis only in having the antennae basally dull flavidous in 
place of entirely piceous, segments two to seven in place of two to four 
testaceous with the remainder pale-margined, the coxae testaceous, black- 
marked in place of entirely black, the femora slightly paler apically, and 
the hind tarsi with base and apex of their tibiae darker; he only instances 
one at all reliable point of distinction in the greater facial prominence of 
P. pratensis. ‘Thomson differentiated P. pratensis by its basally black 
anterior femora, exactly as those of P. propinqguus are described by Pfan- 
kuch; and P. propinquus by its “ pleura concinne punctata,” while Holm- 
gren gives both as “ pleuris nitidis, parse et remote punctatis.” Specimens 
of the former from Scotland, named by Bridgman, agree ad amussim with 
specimens of the latter, named by Capron, in my collection, excepting in 
femoral colouration; the hind tibiae are often apically nigrescent with 
entirely pale tarsi. Thomson distinguished both under the subgeneric 
name Z7ichocalymmus on account solely of their densely tomentose cly- 
peal foveae. I have seen Stephens’ single ¢ 7Z. obscurus in the National 
Collection.
