5^ BRITISH ICHNEUMONS. {Acanthocryfytus. 



This species occurs throughout Europe, extending to northern Africa, 

 and is not very uncommon in Britain. Stephens records both sexes as 

 uncommon about London, in June, and the male in July ; Tuck has taken 

 it at Tostock, in Suffolk, in early September; and I found it on the flowers 

 oi Afige/ica sylvestris at Harkstead, in the same county, on the first of the 

 same month, 1903. It has been bred from Depressaria heracleana and 

 D. depressella (cf. Entom. 1882, p. 276). Dr. Capron found it at Shere, 

 in Surrey; and Chitty in September, 1890, at Oflfchurch Bury, near 

 Leamington.

Head black, with the internal orbits rufescent. Antennae compressed 

 and slightly incrassate towards their obtuse apices, half the length of the 

 body ; joints eight to twelve white and the two basal flagellar red. Thorax 

 with mesonotum red ; metathorax finely coriaceous, with incomplete areae ; 

 lateral costae extending from near the circular spiracles to the slender and 

 acute apophyses ; areola sub-pentagonal, apically trisinuate ; costulae and 

 apex of basal area wanting ; petiolar area discreted. Scutellum red. 

 Abdomen glabrous and nitidulous ; black, with two basal segments red, 

 the second bearing an infuscate fascia ; fifth to seventh white-margined ; 

 basal segment laterally nearly straight, dorsally smooth, with inconspicuous 

 spiracles ; terebra about half length of abdomen. Legs normal and black ; 

 tarsi, anterior and base of hind tibiae, and apices of anterior femora, red. 

 Wings clouded ; radix testaceous, tegulae red. Length, 6 mm. 



There is no clue to the true position of this female, whose clypeus is 

 not described. Gravenhorst placed it in his genus Cryptus, because it was 

 similar in conformation and facies to C. minuiorius^ whence it was removed 

 by Taschenberg on account of its stouter legs and antennae. The red 

 thorax and stout apophyses recall certain species of Rhembobius, but the 

 petiolar area is not described as quadrituberculate, nor do we know the 

 shape of the basal area. It agrees in the costation of the metathorax 

 very well with Microcryptus Spinolae, near which I had placed it, till 

 Schmiedeknecht, in 1905, treated it as a mere variety o{ flagitator, but 

 its incompletely areated thorax, slender and acute apophyses, apically 

 trisinuate and basally confluent areola, obsolete costulae, the coloration 

 of the legs, the black third and darkly fasciated second segment so abun- 

 dantly distinguish it that I tentatively place it under that species for the 

 sake of convenience only, since we know it as indigenous solely from 

 Stephens' unreliable record : " Near London, rarely in June ".J

Head black, with mouth, face and the frontal orbits to the vertex, red. 

 Antennae black, with the five basal joints, except the upper side of the 

 scape, red ; the eighth to the eleventh white. Thorax red, with the pro- 

 notum, a pectoral mark and the scutellar region, black. Scutellum red.
