6 BRITISH ICHNEUMONS. {Coelocryptus. 



lower tooth the larger; genal costa continuous; $ face immaculate. 

 Flagellum of $ centrally incrassate. Mesonotum sparsely and strongly 

 punctate ; epicncmia entire and reaching wings ; metathorax hardly areated, 

 basal area indicated ; s|)iracles somewhat large, oval. IJasal segment with 

 no dorsal carinae. Apical margin of the hardly spinulose hind tibiae trun- 

 cately dilated and externally orbiculate ; anterior obviously spinulose. 

 Lower angle of the discoidal cell neither acute nor further from the base 

 than the centre of the areolet, its external fenestra entire. Size not small. 

 Ashmead (Proc. U. S. Museum, 1900, p. 185) sinks this genus as 

 synonymous with Schenkia, Forst. (Verh. pr. Rheinl. 1868, p. 184), but I 

 do not find that the latter's definition justifies this conclusion ; moreover, 

 Thomson gives C. rufinits as the only exponent of this genus, relegating 

 C. graminicola, Grav., indicated as typical of Schrankia by Ashmead, to 

 Microcryplus, and adds that " Troligen ar Foersters Colocnema identiskt 

 med detta sliigte " ( Coelocryptus).

Head narrower than thorax, shining black ; clypeus transverse, coarsely 

 punctate, apically truncate and sub-reflexed ; palpi pale ; mandibles of ? 

 basally badious, of c? centrally flavous ; $ with epistoma not prominent, 

 with a rosy mark on either side. Antennae of $ attenuate and black with 

 scape rufescent beneath, of 9 infuscate, centrally incrassate, with the 

 eleven basal joints ferrugineous. Thorax sub-convex ; epomiae and notauli 

 short; mesonotum and metathorax sparsely pubescent, the latter short and 

 shining, of $ exareolated with the pleural costa entire, of ^ with the 

 quadrate areola, the discreted petiolar and basal area, complete; meso- 

 sternum short, laterally sparsely punctate and shining, its sulci somewhat 

 deeply impressed and not reaching the centre. Scutellum black and 

 somewhat convex. Abdomen hardly narrower in $ than thorax, shining 

 and obsoletely punctate, of $ sericeous ; testaceous-red, with segments 

 five to seven and perhaps the base of the first black, the anal two in the ? 

 retractile and bearing a whitish membrane ; basal segment glabrous and 

 nitidulous, elongate and slightly curved ; post-petiole gradually dilated 

 apically, hardly margined laterally, with no dorsal carinae though centrally 

 foveolate ; ventral fold prominent and the infuscate terebra hardly half the 

 length of the abdomen. Legs somewhat stout, red ; coxae, trochanters, 

 and the hind femora, black. Wings somewhat narrow and clouded ; radix 

 stramineous, stigma and tegulae fulvous. Length, 8-10 mm. 



In size and conformation, particularly of the wings, it closely resembles 

 G. cofigruens, from which the immaculate scutellum and the absence of 

 the pale flagellar band will at once distinguish it. 



Gravenhorst records the male from Netley in Shropshire and Stephens 

 from near London in June. Dr. Capron has more recently taken it at 

 Shere, in Surrey ; but it does not appear to have been noticed elsewhere 

 in Britain, nor to have been bred.^
