52 THE ENTOMOLOGIST. 
parthenogenesis occurs the same as with some species of 
gallflies. 
The imago is only from four to five millemetres long, and 
expands to one centimetre. The whole body is shining 
black. The head is broad and but slightly projecting, and, 
together with the thorax, is covered with very fine, silky 
pubescence. The eyes are widely separated; they are of an 
elliptical shape and moderately projecting, and are of a 
bronzy tint. The antenne are black; they are as long as the 
abdomen, and are entirely similar in form to those of other 
species of Nematus,—for example, Vallator. The external 
angles of the prothorax towards the insertion of the wings, 
and the tegule, are of a reddish white. The anterior legs, 
from just above the knee, are of the same tint, which becomes 
somewhat darker towards the tarsi; the intermediate and 
posterior legs are also reddish at the knee, but the femora 
and tarsi are of a faded gray; all the apophyses and the tips 
of the coxe are likewise of the same reddish tint. There is 
nothing remarkable about the transparent, more or less 
iridescent, wings; the nervures are of a faded earthy black, 
with the exception of the larger nervures at the insertion of 
the wing, where they are of a sordid white. 
List of the Best Insects taken at Whittlesford during the 
past Season. By A. THURNALL, Esq. 
Cheerocampa porcellus.—Several flying on sweet-william 
flowers, and the larve on Galium. This species seems to be 
much more common here than C. Elpenor. 
Sesia ichneumoniformis.—Three flying in sunshine; one 
depositing its eggs at the roots of birds’-foot trefoil. 
Liparis chrysorrhcea.—t\ found a “nest” of the larve on 
whitethorn, from which ] bred a large number of insects. I 
have never taken it here before. 
Ennomos fuscantaria.—Two pupe and two larve; all 
spun up on the leaves of ash. They hatched in due time, 
two males and two females. 
Geometra papilionaria.—Three specimens flying in woods. 
Corycia taminata.—F our specimens flying in woods. 
Scotosia certata.—One flying over barberry flowers.
