294 BRITISH ICHNEUMONS. \Aritranis. 



slender and piceous, with tlie basal flagellar joints apically sub-nodulose 

 and the strongly excised scape bright red. Tiiorax brick-red, with meso- 

 pleurae and sternum, the scutellar region and whole metathorax, except 

 two dots in the basal lateral areae, black ; mesonotum finely scabrous 

 and villose, with notauli extending to the deplanate disc ; metathorax 

 obsoletely reticulate, with distinct pubescence and the petiolar area longi- 

 tudinally rugose ; apical costa straight and entire, basal centrally inflexed 

 towards the base before which it diverges to form the basal area ; areola 

 elongate and laterally indeterminate ; spiracles small and circular. Scu- 

 tellum red and obsoletely punctulate. Abdomen elongate and laterally 

 only slightly curved ; brick-red, with extreme base of petiole piceous and 

 the three apical segments narrowly margined with clear stramineous ; basal 

 segment gradually explanate and evenly punctulate throughout, laterally 

 bordered and dorsally carinate ; the three following segments punctulate, 

 apically sub-callose and shining ; terebra about half the length of the 

 abdomen, piceous, with spicula sanguineous. Legs red, with tibiae 

 stramineous ; front tibiae strongly inflated, hind ones apically and before 

 the sub-incrassate centre piceous ; onychii normal, infuscate. Wings 

 somewhat narrow and slightly clouded ; stigma piceous, basally paler ; 

 radix and tegulae white ; areolet with inner nervure oblique and the outer 

 totally wanting, fenestrae broadly discreted ; nervellus post-furcal and 

 intercepted far below its centre. 9 . Length, ^\ mm. 



The incomplete areolet allies this species to Hemiteles, but its elongate 

 form, incrassate tibiae, acuminately dentate clypeus and tomentose thorax 

 all point to a Cryptid position and agree with this genus in which it 

 appears, however, somewhat incongruous on account of its normal onychii 

 and abnormal areolet. 



I possess but one female, which was captured by Mr. Bignell at Oreston 

 Quarry in Devonshire, on ist August, 1884. Since writing the above I 

 have seen a second female of this species in Marshall's collection (in Brit. 

 Mus.) ; it was taken at Corn worthy, near Totnes, in Devonshire, and is 

 labelled ^^ defediviis, Bridg.," which name was never published.

Head narrowed behind the eyes, very finely and closely punctate, black 

 with close white pubescence ; face more strongly and confluently punctate, 

 slightly prominent centrally, of $ with epistoma and facial orbits broadly 

 white ; clypeus discreted, sub-glabrous, apically produced, of $ entirely 

 and of $ sometimes centrally white ; mandibles stout with equal teeth ; 

 palpi infuscate, of <? basally white. Antennae slender, filiform, apically 

 obtuse ; of $ sometimes with three central joints obsoletely white above.^ 

 Thorax sub-cylindrical, of ? deep red, with prothorax, scutellar region, 

 and usually the mesosternum and areola black, of $ black, with more or

 may not be white-banded.
