Microcryptus?^ BRITISH ICHNEUMONS. 3I 



ones with apices of trochanters, extreme base and apex of femora, and the 

 basal tiiird of the tibiae, with the calcaria, fulvous-red ; the two central 

 joints of the hind tarsi white and the tibiae somewhat spinulose. Wings 

 sub-flavescent ; tegulae piceous, radix flavous ; discoidal cell externally 

 obtuse below ; nervellus intercepting the slightly antefurcal recurrent 

 nervure below its centre. Length, 8-10 mm. 



This male is said to be very closely allied to M. perspicillatfli- and arro- 

 gans ; from the former it differs in the black anus and from the latter, of 

 which it is perhaps no more than a variety (allied to var. l>, Thoms.), in 

 the immaculate orbits. 



? . Head only slightly narrowed posteriorly, immaculate. Antennae 

 filiform and only very slightly incrassate apically, with the basal flagellar 

 joints discreted and the central four or five white. Mesothorax with some- 

 what long and fine pilosity, notauli distinct and the central depression 

 broad and shallow ; propleurae longitudinally strigose, mesopleurae 

 rugosely punctate ; metathoracic areae as in J , with the petiolar large 

 and hexagonal with obliciue marginal striation and strong apophyses. 

 Abdomen oval and somewhat deplanate, with the second, third and apex 

 of the first segments red ; basal segment parallel-sided to its centre and 

 thence explanate to apex ; post-petiole strongly canaliculate, bicarinate 

 and apically explanate laterally ; seventh with apex white and terebra one- 

 third length of body. Legs black, with anterior femora (except base of 

 front femora), tibiae and tarsi, and sometimes base of hind tibiae, red. 

 Wings with stigma piceous. 



Kriechbaumer, who recognized neither his own former species nor 

 Bridgman's as the male of his iM. a?-matus, says it is probably most 

 closely allied to M. arrogans, from which it differs specifically in the 

 colour of the anterior legs and the white-marked anus, though the obtusely 

 triangular or sub-acute apophyses are its most distinguishing feature. 



Bridgman described this species from males taken at Mousehold Heath, 

 near Norwich, early in October, 1881. The female is described from 

 Corfu and, perhaps, also Piedmont ; it is synonymized by Schmiedeknecht, 

 but has never yet been recorded in Britain. 1 possess males captured by 

 Dr. Capron, at Shere, in Surrey, and a single female, captured in July at 

 Huntingfield, by Chitty.
