THREE NEW ICHNEUMONS. 265 
and intermediate coxe fuscous, more or less pale at the apex, 
and the hinder ones black. 
Fifteen males and nine females bred by Mr. Weston from 
galls, 1878—9. 
Cecidonomus gallicola, n. sp. 
Length 4—6 mill., female. Black; legs red, coxe and tro- 
chanters black, apex of hind tibie and tarsi sometimes fuscous. 
Head and thorax finely alutaceous, first three segments finely 
alutaceo-punctated, rather more coarsely marked than the thorax, 
the remaining segment glabrous; areze of metathorax not so 
distinct as in the former species, and in form an irregular hexagon, 
broader than long, narrower in front than behind in the female, 
more regular, about as broad as long in the male; wings with no 
areolet, transverse anal nervure divided in or just below the 
centre ;- antenne about two-thirds the length of the body; aculeus 
a little longer than the abdomen. Male like the female, but has 
the front and intermediate coxe fuscous at the base, the hinder 
entirely so; trochanters red, except the base of the hinder ones. 
The finer sculpture, shining apex of the abdomen (and dark 
coxe and trochanters in the female), readily distinguish this species. 
Two males and four females bred by Mr. Weston from galls, 
1878—9. I have taken three males at Norwich. 
Cecidonomus ? rufus, n. sp. 
Length 4—5 mill., female. Black; 2nd and base of 38rd 
segment of abdomen and legs red, the apex of intermediate and 
posterior tibiz and tarsi more or less fuscous. 
Head and thorax finely alutaceous ; abdomen densely and finely 
punctured on the 1st segment running into each other; antenne 
about two-thirds the length of the body. Wings without areolet, 
transverse anal nervure broken below the centre; arez of meta- 
thorax distinct, supero-medial varies from a blunt-ended pentagon 
to a blunt-ended hexagon, about as broad as long, the lower side 
areee being shorter than upper ones; aculeus as long as the 
abdomen and distinctly curved downwards. 
Two females bred by Mr. Weston from galls in 1878, and one 
in 1879. I have also taken two females near Norwich. 
Erratum.—Page 261, under Leprporrersa. Heusimene fimbriana, Catoptria 
Juliana, should come after C. argyrana in the previous line, among the species 
bred by Mr. Weston.
