slender, and has the first segment of the abdomen longer and 
narrower, etc. 
Octonarius, Ratz.* 
Also a shining species, having the first abdominal segment 
almost smooth with only a few scattered punctures, and half as 
long again as its apical width; the second segment has two 
impressed lines enclosing a subtriangular, subcarinated space, 
which is also almost smooth. 
I have seen a specimen from Bridgeman’s collection named 
by Marshall (see ‘ '‘'rans. Entom. Soc.,’ 1885, p. 210), and have 
also examined a brood in Marshall’s collection in the British 
Museum. On July 11th, 1911, I obtained fifteen (eleven males 
and four females) from a larva of Notodonta ziczac. . 
Cocoons white with a very faint lemon-coloured tinge, 
constructed in an irregular cluster. 
Jugosus, sp. NOV. 
Black ; palpi pale; belly at base fusco-testaceous; cox black or 
blackish; fore femora testaceous with the base dark, middle dark 
with the apex testaceous, hind entirely dark, or dark above and below 
with a medial testaceous stripe at sides, or occasionally almost 
entirely testaceous; fore tibize testaceous, middle and hind tibiz 
testaceous with the apex dark; fore and middle tarsi testaceous, 
hind tarsi fuscous. Wings hyaline, stigma fuscous. Antenne of 
female as long as the body, of male rather longer. Mesothorax 
finely punctulate; scutellum and metathorax almost smooth, the 
latter with a medial longitudinal depression. First segment of the 
abdomen punctulate, truncate, twice as long as medial breadth, with 
subparallel sides (rather broader in the female than in the male), 
second as long as third, with two converging impressed lines ending 
midway in irregular fovee; other segments smooth and shining. 
Hind cox smooth and shining; spurs of hind tibie rather shorter 
than half the metatarsus. Terebra very slightly exserted. 
Length 23-3 mm., expands 7 mm. 
Occasionally the first two abdominal segments are margined at 
ine sides with testaceous, and the belly at the base is also of that 
colour. 
Described from seven males and two females. Somewhat 
close to glomeratus, though the smooth metathorax easily dis- 
tinguishes it from that species. From immumnis it differs, among 
other things, in having the first segment of the abdomen much 
longer in comparison to its breadth. 
The cocoon is very pale lemon colour, but soon fades; for 
this reason it is often quite white in cabinet specimens, also in 
cases where it has been exposed to damp through the winter it 
becomes almost brownish. Round the capital extremity of the 
cocoon is a raised ridge which appears.to guide the insect when
