Cratocrypius.] BRITISH ICHNEUMONS. IJ 



black. Abdomen black, with the apical margins of the two basal segments 

 often castaneous ; of ? oblong-ovate, of S narrower than the thorax and 

 fusiform ; first segment of ? gradually strongly dilated towards the apex, 

 and the seventh with a white membrane ; terebra straight and distinctly 

 shorter than the abdomen. Legs red ; all the coxae and trochanters of 

 the (?, but only the front coxae occasionally of the 9, black; all the 

 femora red and somewhat stout. Wings a little clouded; radix dull 

 white ; tegulae of S white, of ? black ; areolet broad and parallel-sided, 

 emitting the recurrent nervure from its centre. Length, 6 mm. 



The male sometimes has the scape beneath, and the trochanters, white ; 

 it is very like that of C. stomaticits, but the areolet is longer and exactly 

 quadrate, besides the mesopectoral conformation. 



Found in June, near London (Stephens) ; Brundall, Heigham osier 

 carr, and taken at Lynn by Mr. Atmore (Bridgman) ; Acomb Wood, near 

 York, and bred from Emphytus ductus (Wilson); Essex (Harwood); 

 Wellington College, Berkshire, in April (Hamm). I have recorded the 

 male of this species from Barnby Broad, in Suffolk (E.M.M. 1899, p. 209), 

 under the name Cryptus erythropus, querying at that time the certainly 

 incorrect synonymy with Cryplus lugu/>ris, Grav. ; it was taken upon the 

 flowers of Angelica sylvestris in a very marshy spot towards the end of 

 August, and about the same time I swept a second male in a marshy 

 meadow at Henstead, in Suffolk. I have not again met with it, which 

 circumstances, added to Bridgman's localities, lead me to think it is a fen 

 insect. Dalglish has given me the female from Bigmopton, in Scotland, 

 taken early in May ; Piffard, from Felden, in Herts. ; and Tuck a male 

 from Benacre Broad, on the Suffolk coast.

Head with clypeus distinctly discreted and apically truncate ; face 

 somewhat coarsely punctate in ? , more finely in $ ; frons centrally im- 

 pressed, strongly and somewhat closely punctate with the interstices 

 reticulate ; $ with clypeus and the internal orbits flavous. Antennae of ? 

 normal, centrally white-banded ; basal flagellar joint twice longer than 

 broad and longer than the second, the sixth quadrate. Thorax immacu- 

 late ; mesonotum closely and finely punctate, with the notauli more distinct 

 in $ ; metathorax finely rugose-punctate, with the apical transverse costa 

 laterally distinct and the sides of the ill-defined areola weakly indicated ; 

 spiracles ovate. Scutellum black, shining and somewhat sparsely punctate. 

 Abdomen smooth, shining and immaculate ; of 9 ovate, with the basal 

 segment gradually dilated throughout and the second transverse, of c^ with 

 basal segment slender and hardly apically broader than the petiole, its 

 spiracles minute ; the three following segments elongate with the fifth 

 transverse; terebra three-cjuarters of the length of the abdomen. Legs 

 somewhat slender, black ; the hind tarsi piceous and centrally white ; 

 apices of the front femora and, in 9 , of their tibiae and tarsi, red ; c^ with 

 anterior tibiae and tarsi fulvous, with base of the hind tibiae and femora 

 red. Wings with tegulae dull stramineous. Length, 6-9 mm,
