SATYIUDM. 
male, and only sometimes in the female ; all the spots are much 
about the same size, hut the foremost two are approximated. 
Hind wings unicolorous dark brown, without any markings. 
Under side : Fore wings the same as above, but the spots are 
somewhat smaller, and there is some slight greyish coloration near 
the apex and along the hind margin ; hind wings greyish brown, 
with a broad central brown band dentated in outline ; there are no 
white markings. The marginal fringes are dirty white, spotted 
with dark brown. PI. LXIV., 3. 
Time of Appeakance. — July. 
Habitat. — Marshy places in Lapland, in Umea, Tornea, &c., 
flying over the flowers of Euhus chamcemonis (Wallengren). 
Lakva. — Unknown.

Chakactees. — Larva unknown in all hut two species. Scudder 
figures and describes the various states of (E. Semidea; in this 
case it is fusiform, with the anal extremity scarcely if at all forked, 
and has conspicuous dorsal and lateral stripes of a dark green 
colour. The larva of (E. Semidea is described by Scudder as 
feeding on lichens ; that of (E. Bore is believed by Sandberg to 
feed on grasses. 
Pupa (of GE. Semidea ). — Compact and rounded, with the head 
obtuse and regularly rounded ; abdomen cylindrical, tapering very 
regularly and rather rapidly to the apex, which is blunt ; ventral 
surface somewhat flattened. Mode of pupation not properly 
ascertained ; but probably the pupa lies upon the ground and in 
crevices of rocks, and is not suspended. 
Imago. — Anteume rather short, with a gradually formed club. 
Eyes naked. Wings medium size, with the nervures of the fore 
wings very little dilated at the base. Discoidal cell of fore wings 
closed ; the colour of the wings is brown, lighter than the general 
colour of the last genus, and they usually have a submarginal band 
of a still lighter colour containing black spots, which are often 
ocellated. The hind wings beneath are sprinkled with white and
