known on the Continent. They much resemble each other in 
outward appearance, but are easily separated by the forms of the 
anal appendices of the males. 
1. Apatania vestita, Kolenati. 
(Pl. 1V. fig. 9, neuration and palpi; PI. XI. fig. 18, app.) 
Apatania vestita, Kol. Gen. et Spec. Trichop. pt. 1, p. 76, 1

Antenne, head and thorax black; the head and prothorax with 
greyish pubescence. Anterior wings pale greyish-fuscous, thickly 
clothed with short brownish-grey pubescence, rather darker at the 
pterostigma ; a pale spot at the thyridium and another on the costa 
just before the pterostigma; veins fuscous ; discoidal cell concave 
on its superior margin ; first apical cell narrow at the base ; second 
and fourth of nearly equal breadth throughout, truncated at the 
base; third much longer than the second, base slightly narrower, 
two-sided; fifth very acute, scarcely reaching the anastomosis ; 
sixth extending further than all the others, two-sided at the base ; 
the others short and broad. Posterior wings subhyaline, with fine 
greyish pubescence and long grey cilia. Legs with the thighs 
fuscous, testaceous towards the knees; tibiae and tarsi testaceous, 
with fuscous spines; terminal tarsal joints somewhat fuscous. 
Abdomen blackish with reddish-brown lateral lines; the three 
terminal segments fringed with long hairs; app. sup. apparently 
absent; app. intermed. fine, slightly curved, hairy, united at the 
base into a broad plate, yellow; between and above the app. 
intermed. is a long fine needle-shaped yellow spine, exceeding 
them in length, and directed slightly downwards; app. inf. very 
long, bisarticulate, curved strongly upwards, the joints of nearly 
equal length ; first joint stout, rather dilated towards the truncated 
extremity, fuscous and fringed with long fuscous hairs, second 
joint obtuse at the apex, which has a slight downward curve, 
yellowish at the base, fuscous at the apex, the whole very thickly 
clothed with short fuscous hairs; upper penis-sheaths broad, 
approximating, yellow at the base, fuscous towards the obliquely 
truncated apex; penis not so long as the upper sheaths, yellow, 
the apex split; beneath the penis lie two very small needle-shaped 
fuscous lower sheaths. 
An old specimen is in Mr. Newman’s Collection. I possess 
examples from the Lake District, and in June last captured it in 
abundance on the shores of Loch Rannoch. I found females of 
an Apatania at Arundel which may belong to this species, but
