The Swedish species of this genus are L. scarodactylm, L te, 
dactylus, L. microdactylus, L. osteodaotylus, and Z. Irachydactylu, 
own British species are also five, namely, L. Lienigianu., L. ter 
dactylns, L. mierodactylus, L. osteodactylus, and L. brachydJl 
Ihere is no reason why scarodactylm, tl>e larva of which feeds on 
blossoms of meracium umlellatum and H. horeale in August 
September should not be met with in our country. The moth app 
m J uJy It IS larger than mierodactylus, nearly equal to osteodaci 
m size but not so yellow ; the spots are browner than in microdacU 
and the lower one is not exactly at the fissure, but rather belo. 
the most striking diiference, however, is in the dark grey fringe in 
upper wings of scarodactylus, contrasted with the pale brown frii 
m mierodactylus.

The Scandinavian species of this genus are only two, namel 
Actpttlus tetradactylus and A. pentadactylus. The larva of tetradactyl 
13 said to feed on Thymus serpyllum, in May and June. In Britai 
we fortunately have several more of this genus, viz., A. galactodactyh 
A^ spilodactylus, A. ballodactylus, A. tetradactylus, and A. pentadactylu 
Paludum certainly does not belong to it, the much longer palpi andtt 
shghtly thickened tibiae would be quite enough to distinguish i 
Ihe only insect known to me in this group as likely to pass in ou 
cabinets undetected is xanthodactylus, which might be overlooked as 
variety of haliodactylus. It may -be known by its having a spot on th 
inner margin of the anterior wing, opposite the one on the oute 
margin, as well as a spot at the fissure.
