194 BRITISH ICHNEUMONS. lAtigiiia 



from Nunton in Wilts (Marshall), Rei^fate (W. Saunders), and Lyndliursl 

 in May and June (Adams); Chapman bred a female on loth June from 

 Psyi/ic intcnnediella, found at Bournemouth on Erica; and Brisclike 

 describes the cocoon as "cylindrisch, schwarz oder braun, weiss bespon- 

 nen." It cannot be generally common, for 1 took only nine examples, 

 on A7igelica, Heracleum, Chaerophyllum and luHuiculum flowers, between 

 1895 and 1904 in Cambridge and Suffolk, where Tuck has several times 

 met with it near Bury. What then was my surprise at finding it in the 

 utmost profusion on the windows of Monk Soham House when 1 first 

 came here in 1904! It has occurred annually since that time, I pinned 

 over eighty specimens and then tired ; the male occurs from 23rd May 

 to loth September, though not at all in July, and it is fully three-quarters 

 rarer than the female, which has been taken from 14th May to i ith Octo- 

 ber, is rarest in July, and upon two occasions 1 have noted it on 27th 

 December; it not infrequently flies to lamps, always about 9 p.m.; I 

 suspect it of preying upon Endrosis fencsirella, the common clothes moth.

Campoplcx lateralis, Gr. I.E. iii. 467, ? . Liutncria lateralis, Bridg. -Filch, 

 Entom. 1885, p. 106, ? . Aiigitia lateralis, Thorns. O.E. xi. 1157. ? . 



A black species with red legs, exactly like the last two in structure, in 

 the regularly triaiigularareolet emitting recurrent nervure from its centre, 

 the entirely pale anterior trochanters, narrow head and pale underside of 

 the scape. Length, 5 mm. J 9 • 



The female differs from the two preceding in having the terebra only 

 one-third in place of half the length of the abdomen, which bears a very 

 much more definite lateral mark on the third and rarely also on the 

 second segment, its stigma is somewhat narrower, but it is recognised at 

 once by the unicolorous fulvous hind tibiae with no black markings. 

 The male has not hitherto been known, and was doubtless mixed with 

 other species ; it is the commoner sex in Britain and agrees in every way 

 with those of the two last species, excepting in its strong abdominal 

 marks and unicolorous hind tibiae and femora. 



Very little seems to be known of this species, which is recorded only 

 from Silesia and Piedmont ((iravenhorst) and Esperod in Sweden (Thom- 

 son). Desvignes included it in his 1856 British catalogue, but our only 

 record is by Bignell "captured at Cornwood, 21 May; Bickleigh, 19 

 June," in south Devon. It is not very rare with us and 1 possess a score 

 of specimens, found at Reigate by Saunders, Felden by Piffard, I'udden- 

 ham Fen in August by Elliott, Tostock by Tuck ; Chapelizod, Dublin, 

 on loth May bv Stanley Kemp; and bred by Chapman from Fuiiica casta 

 at Lugano. It' has occurred to me in the Isle of Wight at Ryde, in Essex 

 at Gosfield, in Norfolk I took the typical male in Wroxham Broad on 

 14th June, 1 90 1, with others in Surlingham marsh; and in Suffolk it is 

 found on reeds at Covehithe, carrot flower at Monks Soham, in Tudden- 

 ham Fen, Henstead marsh, Beccles, Mildenhall and in August sitting 

 on grass stems at Brandon, always in very marshy spots.
