292 BRITISH ICHNEUMONS. [ Polyblastus 
teeth of equal length. Antennae stout and two-thirds length of body, 
with flagellum centrally white-banded and scape piceous beneath. 
Thorax with notauli obsolete ; metanotum shining, with areola subquad- 
rate and apically a little explanate. Scutellum large, subpyramidal and 
apically truncate. Abdomen stout and black, hardly longer than head 
and thorax, with all the segments testaceous-margined ; basal segment 
rugulose, curved, strongly bicarinate nearly to its apex and but very 
slightly constricted basally, with spiracles obsolete and a little ante- 
central; second segment rugulose and transversely impressed, the follow- 
ing smooth and shining; venter rufescent; terebra stout, straight and 
distinctly a little exserted. Legs short and stout, the anterior with hind 
coxae and trochanters testaceous; remainder of hind legs piceous; 
tarsal claws stout and pectinate. Wings subhyaline with nervures 
nigrescent, radix and tegulae clear testaceous, stigma basally pale ; 
areolet subpetiolate and somewhat regularly triangular. Length, 10 mm. 
The short legs and stout abdomen lend it much the appearance of 
Erromenus. 
This entirely distinct species, described from Lower Austria by Dr. 
Giraud who took but a single female at Prater near Vienna in the middle 
of September, is recorded by Rev. T. A. Marshall (E.M.M. 1897, p. 150) 
from Botusfleming in Cornwall, “I find it here occasionally in hedges; 
it varies much in size; no @ has yet occurred.” There are two specimens 
thence in his collection in the British Museum. In his own copy of the 
1872 Catalogue, which I possess, he has doubtless correctly entered it as 
synonymous with P. grossus, which Brischke took at K®6nigsberg, thus 
linking up the above records.

terior legs fulvous, with the coxae at least basally black; hind legs black; 
with apices of coxae and of trochanters stramineous, tibiae testaceous

stigma and radius infuscate piceous, radix and tegulae stramineous; areo- 
let wanting. Length, 5 mm. 
?. Somewhat shining, finely punctate and black with the mouth and 
two apical facial marks flavous, abdomen centrally and the anterior legs 
red. Clypeus slightly deplanate before its apex; antennae shorter than

black, flavous beneath. Metathorax semiglobose with distinct upper areae. 
Scutellum not pyramidal. Basal segment margined, subrugose, basally a 
little convex, gradually dilated towards its deplanate apex, with distinct

Brischke says the colouration of the @ legs is variable,
