Omorga'] BRITISH ICHNEUMONS. 157 



body, witli scape pale beneath. Thorax with mesopleurae finely punctate 

 below and speculum glittering; nietathoracic costae very prominent, with 

 lateral areae subdiscreted; areola pentagonal, about as long as broad and 

 parallel-sided. Abdomen black with extreme apex of second segment 

 distinctly but narrowly red, and ventral plica stramineous ; postpetiole 

 longer than broad, laterally slightl}' rounded in 9 and nearly straight in (J, 

 longer and broader than petiole ; second segment nearly a third longer 

 than broad, and remainder transverse ; terebra somewhat longer than a 

 third of the abdomen. Anterior legs red with femoral basi' and coxae 

 except sometimes apically black, and trochanters partly infuscate ; J 

 with anterior coxae flavous-marked beneath ; hind legs black with apices 

 of coxae and rarely most of femora red, their tibiae centrally and some- 

 times at extreme base ferrugineous, as also is base of their tarsi. Wings 

 with stigma infuscate-testaceous and somewhat narrow, radix and tegulae 

 stramineous ; areolet petiolate, emitting recurrent nervure beyond its 

 centre; nervellus antelurcal and slightly geniculate far below its centre. 

 Length, about 5 mm. 



This species has been nowhere noticed since first described. 



"Bred by Mr. W. H. B. Fletcher from 7)ychtns aurana from Sleyning, 

 and Psyche intirmcdicUa, and also from either Hysipelcs rubcrata or Grapho- 

 lilha campoliliana from Stornoway." — Bridg. I.e.

Head with the vertex short, narrow and subtriangular ; clypeiis convex 

 with its lateral fo\eae, the peristomium and mandibles small. Antennae 

 with flagellum sometimes incrassate. Thorax subcylindrical ; nietathor- 

 acic areola elongate, emitting costulae before its centre. Abdomen with

 Thorns. O.E. xi. 1887, 1135. 



Head anteriorly subtriangular, vertex short and narrow, eyes large ; lateral clypeal foveae some- 

 what distinct; mandibles and peristoniiinn small. Antennae of ? with flagellum white-banded 

 above. Thorax elongate, with mesopleurae longitudinally rugose and speculum somewhat dull; 

 metanotum with areae, the areola transverse with stout costulae. .abdominal petiole elongate and 

 slender, with no lateral sulci; postpetiole suboval ; second segment elongate with spiracles beyond 

 its centre ; terebra not exserted. Legs somewhat slender with fine and inequal calcaria, small 

 unguiculi and claws. Wings with areolet large, broad and petiolate, emitting the subvertical recur- 

 rent nervure with its punctiform fenestra before centre ; apex of discoidal cell broader than its base, 

 and a little longer than the brachial cell ; nervellus obliipie and not or hardly geniculate. 



Schmiedeknecht says the females of this genus are "easily recognised by the white-banded 

 antennae ; in this they remind one of the genus Cyvuidusa. In the males the white-band is wanting ; 

 they may be known by the large areolet and by the position of the recurrent nervure ; thus they have 

 a certain resemblance to many species of S(i^rtrr7is." Only two, probably synonymous, species are 

 known.

 Callidora albovincta, Thorns. O.E. xi. 1136, S ? . 



Body finely rugose, dull, somewhat densely whitish pubescent. Black ; palpi, labrum and mandi- 

 bles except teeth pale yellow. Flagellum in ? with a broad white ring on inner side. Wings 

 slightly clouded, stigma brownish, tegulae yellowish white. Anterior legs rufescent, trochanters and 

 coxae paler, latter basally blackish ; the hind legs have the coxae and base of trochanters black, 

 femora rufescent, sometimes the extreme apex, very rarely also the base infuscate ; tibiae red- 

 yellow, basally and apically infuscate ; tarsi dark brown The incisure between segments two and 

 three usually brown-red. Ventral fold pale yellow. Length, 6 — 7mm. 



I copy Schm.'s description of this species, which I do not know and of which he takes both sexes 

 inTliuringia; it seems quite unknown elsi'where since it was first found by Prof. Wahlberg very 

 rarely in Hahusia, Sweden. Our claim to it rests entirely upon the Kev. T. A. Marshall's record of a 

 female (Ent. Ann. 1874, p. 143) " F"rom the Dee-side marshes, Braemar. The antennae are semi- 

 annulated with white." This specimen is now in the British Museum and I find it to be nothing 

 but an ordinary female of CvmorfKsn leucocera (q.v. ante).
