136 BRITISH ICHNEUMONS. [Schizopyga. 



only very sliglitly narrowed towards the base. Abdomen subcylindrical, 

 as broad as and a little longer than head and thorax ; first segment a 

 little contracted basally, longer than broad, with obsolete carinae, black 

 but in 9 ^vith more or less of the sides and disc rufescent ; second seg- 

 ment impressed; second to fifth segments subparallel-sided, quadrate and 

 red with the apical margins of the second and usually third, together 

 with the anus, black ; terebra subexserted and reflexed. Legs stout and 

 red; posterior femora of 9 and often ^ apically, the dull white liind 

 tibiae at apex and before the base, black ; posterior coxae basally or 

 nearly entirely and, excepting the base of their joints, tarsi black ; (J 

 with the trochanters entirely, and the anterior coxae apically, flavous. 

 Wings a little clouded ; stigma and 9 tegulae black ; radix and J tegulae 

 white ; first recurrent strong and intercepted a little above the centre. 

 Length, 6 mm. 



The abdomen of the J varies considerably in colour : the type form 

 has the third to fifth segments with the apical margin black ; Graven- 

 horst's var. i has the fifth entirely black, and in his varr. 2 and 3 the 

 whole abdomen is black. 



The 9 is said to be similar in size and outline to S. podagrica, the $ 

 to Polysphmcta varipes, but it is rather more slender than either of these 

 species. 



The above synonymy is entered by the Rev. T. A. Marshall in his copy 

 of the " Ichn. Europ." and is certainly correct ; it is partly referred to (in 

 Trans. Ent. Soc. 1886, p. 373) by Bridgman. 



Panzer took this species uncommonly among Aphides ; Hope sent a 

 black-bodied male (still in his collection) to Grav. from Netley ; Stephens 

 records it from Darenth, in June. On the Continent it is said to occur 

 on oaks, in August and September. Bridgman says it is not uncommon 

 in Norfolk and I possess a female taken there at Horning Ferry, in the 

 middle of September, by Bedwell ; Bignell records it from Bickleigh at 

 the end of July, and Capron took one female at Shere. It has once or 

 twice occurred to me by sweeping willows and reeds by the Lark River at 

 Barton Mills, Sufi'olk, in the middle of June and in late September. The 

 only record of its parasitism is given by Bignell in Buckler's " Larvae," 

 but 1 must own myself sceptical of its accuracy ; he says Adkin raised it 

 from Hdiothis dipsacca. There is a specimen, taken at Plumstead in the 

 middle of September, in Marshall's collection, in the British Museum. 



3. minuta, Gvav. 

 Schizopyga minuta, Gr. I.E. iii. 131, ? . 



Head with the palpi pale stramineous. Abdomen linear-cylindrical, 

 narrower and twice longer than the head and thorax, with the 

 apical margins of the segments subelevated and the second to 

 fifth obscurely infuscate at the base ; terebra as long as the apical 

 dorsal segment, with the valvulae compressed. Legs fulvous with 

 all the coxae and the posterior trochanters black ; posterior tarsi, with 

 the apices of their tibiae and of their femora, nigrescent ; hind tibiae and 

 base of their first tarsal joint stramineous, \\ith a mark before the base of 

 the former nigrescent. Wings clouded ; tegulae black, stigma piceous 

 and radix stramineous. Length slightly over 2 lines (5 mm.). 



This female appears to differ very little from S. podagrica, excepting in 

 its dark posterior trochanters, badious abdomen and somewhat smaller
