236 BRITISH ICHNEUMONS. | Caloglyptus 


6 also with whole face and clypeus stramineous. Antennae of 2 much 
shorter than body, subfiliform with the flagellum basally red and centrally 
white-banded, of ¢ black and attenuate with apical joints discreted and 
setiferous. Thorax dull black and deplanate; mesonotum of 9 often 
with two red vittae; metanotum scabrous with complete areae, petiolar 
area short and areola very narrow, parallel-sided. Scutellum and post- 
scutellum of Q usually rosy apically. Abdomen red, strongly petiolate, 
of Q with 5th segment to apex, or also petiole, alone black, ot ¢ with 
3rd and apex of znd and base of 4th alone red; basal segment elon- 
gately and strongly bicarinate, with subcentral spiracles and, like the 
second distinctly granulate. Legs not stout, red with the @, and rarely 
hind 9, coxae black; hind femora either at extreme apex, or except 
their base, nigrescent ; hind tarsi fulvous. Wings hyaline, with radix and 
tegulae stramineous, latter piceous in @; stigma piceous, basally paler ; 
areolet wanting or traceable. Length, 6—8 mm. 
This description is drawn from eight @ 9 and one g (all that are 
known as British), of which two of the former and the right wing alone 
of the latter bear areolet. ‘Thomson distinguishes this species from the 
rest of its genus by the lack of vertical excavation and areolet, the dis- 
tinct notauli and apically verticillate-pilose ¢ flagellum, later pointing 
out that the short vertex is angulated behind the eyes, pleurae coriaceous 
with polished speculum, antennae of ? short and at most with 25 joints, 
the upper wings not long with basal nervure antefurcal and not curved 
above, radius apically straight, nervellus oblique below centre. 
Ranges through Norway, Sweden, Germany, Belgium and France. 
Stephens found a female near London in June or July, possessed another 
from Donovan’s collection and a third is in Desvignes’. It was intro- 
duced as new to Britain by Bridgman under Holmgren’s name (Tr. Ent. 
Soc. 1887, p. 369), which he had already thought synonymous with JZ. 
antilope (loc. cit. 1882, p. 155), on the strength of examples of both sexes, 
recorded by Capron from the vicinity of Shere in Surrey (Entom. 1880, 
p- 87); these are the specimens here described.
