988 THE ENTOMOLOGIST. 
examples I possess being two ancient specimens which were 
given to me some years ago. Fortunately I have been able to 
inspect a fine series of nine in Morley’s collection, and three in 
that of Col. Nurse. With one possible exception all the speci- 
mens I have examined have the costal cell rather shorter than the 
median, and the recurrent nervure rejected by a distance which 
is equal to or rather less than the length of the first abscissa 
of the radius (fig. 4). Wings yellowish hyaline. The upper 
surface of the abdomen is generally, though not always, fuscous. 
The cocoon I have not seen, and the only description I know 
of is that of Fitch (Entom. xiv. 143), who tells us that it is thin, 
smooth, and white. 
Among Morley’s insects are two females bred by Cockayne 
from larvee of T’eniocampa populeti taken in Berkshire. 
Z.ifumator, sp. nov. (Fig. 2.) 
Thorax, abdomen, and legs, including the hind tarsi, rufo- 
testaceous ; claws black, and also a black dot above the radices. 
Palpi pale testaceous; mandibles fuscous at the tips; antenne 
testaceous, annulated, darker towards the apices, longer than the 
body in both sexes. Metathorax marked with a rather elaborate 
raised pattern, which, though often not so symmetrical as in the 
case figured (fig. 5) (taken from a specimen in my collection, No. 530), 
is always present in a more or less perfect condition. Wings dull 
hyaline, apical half somewhat infumated, costal cell as long as or 
slightly longer than the median. Costa, nervures, and stigma 
fuscous, recurrent nervure rejected by a distance which is greater than 
the length of the first abscissa of the radius. Radial areolet of the 
hind wings not geminated by a transverse nervure. Abdomen smooth, 
terebra not surpassing the anus. Length, 9-11 mm., expands 
17-22 mm. 
Described from thirteen males and eleven females. 
Approaches Z. testaceator in size, but differs therefrom in 
having the terebra concealed, infumated wings, and a shorter 
first abscissa of the radius, &c.; from Z. chloropthalma it differs 
in size and also in the infumated wings, &c. 
Larva dirty cream colour, showing under magnification irre- 
gular white speckles on the last six or seven segments, attenuate 
towards the head, parts of the mouth not or scarcely outlined. 
The cocoon is thick, white, somewhat rough but not woolly, 
attenuated similarly at both extremities, and 103 to 18 mm. in 
length ; when exposed to damp it turns a brownish colour (fig. 9). 
Very many times bred from larve of Boarmia repandata 
between May 4th and June Ist, from which host Major Robert- 
son has also bred it at Chandler’s Ford. The parasite larva 
leaves its host when the latter is full-fed and has retired below 
the ground for pupation, and there spins its cocoon.
