Spilocryptus\ BRITISH ICHNEUMONS. 283 



tarsi, which are red in G. ornafi/s, mainly white and, unlike .S". cimbici<;, no 

 white band at the base of the tibiae. The discovery of the $ has been 

 overlooked on the Continent ; I possess one of the original specimens of 

 this sex from Dr. Capron's collection. 



This species was added to the British fauna by Brids^man (loc. cif.), on 

 the strength of specimens of both se.xes bred in Norfolk by Laddiman. 

 The Continental authors appear to be in some doubt concerning its sys- 

 tematic position, and record it only from the vicinity of Dresden. I 

 possess two females taken by Miss Chawner and myself in the New Forest 

 in August, which differ from the above description in having the tibiae 

 broadly white basally, with the basal half of the first joint and extreme 

 bases of the following joints of the black tarsi concolorous. 



GAMBRUS, Fofster. 



Forst. Verb. z.-b. Ges. 1S68, p. 188 ; Thorns. O. E. xxi. 2374. 



Head and mesonotum dull and entirely black in both sexes ; clypeus 

 very often apically produced or spinose. Metathoracic spiracles circular. 

 Abdomen with anus white-marked ; petiolar spiracles only just behind 

 centre ; post-petiole of S usually margined laterally. Tibiae with no basal 

 white band ; tarsal claws stout, not large, and shorter than second joint. 

 Areolet large and parallel-sided ; nervelet wanting ; nervellus intercepted 

 in its centre. 



Thomson's three new species should, probably, also occur with us, 

 though the sixth one of the European fauna is alpine and, with C. leuco- 

 proctus, Gray., doubtfully referred to this genus, cannot be looked for here.

Head immaculate ; epistoma not prominent. Antennae of $ with fla- 

 gellum centrally white-banded and basally rufescent, with its first joint 

 four times longer than broad. Thorax with pronotum anteriorly red- 

 marked in $, white in $\ metathorax convex, hardly rugose, with both 

 transverse coslae present, parallel and very fine ; apophyses somewhat 

 distinct. Scutellum, and sometimes in $ post-scutellum, white. Abdomen 

 red, of $ linear, of $ somewhat broad, with segments two to four dull, 

 very finely and closely punctate ; fifth and sixth segments black and the 

 anus dorsally white ; basal segment laterally hardly explanate, carinate, of 

 i sub-linear, of $ a little dilated apically, flat and glabrous, with the 

 spiracles hardly projecting ; terebra about half the length of the abdomen. 

 Legs red ; hind ones with apices of the femora and tibiae nigrescent ; 9 

 with front tibiae stramineous, inflated and basally constricted ; $ with 

 coxae and hind tarsi black. Wings somewhat clouded ; areolet penta- 

 gonal ; radix dark stramineous ; tegulae red or black, of $ white. Length, 

 5-8 mm. 



From G. ornatus this species differs in its shorter head, slightly con- 

 vergent areolet ; the white $ scutellum, red pronotal mark and front
