18 BRITISH ICHNEUMONS. | Chorinaeus 

apices of their trochanters alone flavous, the intermediate legs are black 
with the trochanters, femoral apices, tarsi and tibiae pale, and the hind 
tibiae are nigrescent with their base alone pale. It is, too, a much more 
strongly nitidulous insect with the 9 abdomen apically subtruncate, 
having the fifth and not the fourth segment the broadest. 
Nevertheless the records are much mixed and many doubtless refer to 
the last species. 
It has been noted in Lapland, Sweden, Germany, and France. In 
Britain | consider it rare ; Netley in Shropshire, taken by Hope (Graven- 
horst); June, near London (Stephens) ; common in Norfolk and bred by 
W. Fletcher from Aupaectla angustana (Bridgman); near Carlisle in July 
(Routledge) ; swept towards the end of May, 1907, at Foxhall in Suftolk 
(Chitty); Box Hill early in June, 1906 (Newbery); Hastings in early 
June, 1907 (Butterfield). I took a female by sweeping at Matley Bog in 
the New Forest, in the middle of June, 1907. Bignell says (Trans. 
Devon. Ass. 1898, p. 499) that he has bred it on roth February from 
(doubtless forced) Depressaria heracleana and taken it at Bickleigh Woods 
at the end of June and the beginning of August. Marshall found it at 
Bishops Teignton, Govilon, Nunton, Botusfleming, Cornworthy; and 
Pascoe in the New Forest in September. 
3. flavipes, Bridg. 
Chorinaeus flavipes, Bridg. Trans. Ent. Soc. 1881, p. 165, ¢. C. brevicalcar, 
Thoms. Deut. Ent. Zeit. 1887, p. 201, 3 ?. 
A black species with all the tibiae entirely stramineous, the flagellum 
ferrugineous and lower basal nervure strongly postfurcal. Length, 6 mm. 
Very similar to C. cris/afor in size and conformation, but the thorax is 
more nitidulous and sparsely punctate, the antennae are entirely fer- 
rugineous, the basal nervure is not continuous through the median, the 
more coarsely punctate abdomen is never red banded and has stouter 
carinae, the hind femora are black with their extreme apices alone 
rufescent, the metanotal apophyses are stronger, the calcaria obviously 
shorter and the apical is longer than the second hind tarsal joint. 
No doubt can, I think, remain respecting the above synonymy, not 
previously noted. 
Thomson found this species in southern Sweden, and Bridgman a 
single individual near Norwich in August, 1878; subsequently (Trans. 
Norf. Soc. 1893, p. 628) he says, “I took a single specimen on Mouse- 
hold in August, 1872,” but the latter year must be a misprint. It is 
probably much mixed with the preceding ; I have three examples of each 
sex in Capron’s collection from Shere in Surrey, and a Q which was 
“bred on May 31st, 1903, from Salebria_ formosa, Haw., at Ashford in 
Kent; E. R. Bankes.” Harwood found a couple at Colchester in 1904. 
4. longicornis, Thoms. 
Chorinaeus longicornis, Thoms. Deut. Ent. Zeit. 1887, p. 201, ¢ ?. 
A black species with the legs except basally red, the @ antennae dis- 
tinctly longer than half the body and those of the @ hardly shorter than 
the whole insect, Length, 7 mm.
