The Swedish species of this genus are L. scarodactylus, L. tephra- 

 dactylus, L. microdactylus, L. osteodactylus, and L. br achy dactylus. Our 

 own British species are also five, namely, L. Lienigianus, L. tephra- 

 dactylus, L. microdactylies, L. osteodactylus, and L. brachydactylus. 

 There is no reason why scarodactylus, the larva of which feeds on the 

 blossoms of Hieracium umbellatum and H. boreale in August and 

 September, should not be met with in our country. The moth appears 

 in July. It is larger than microdactylus, nearly equal to osteodactylus 

 in size, but not so yellow ; the spots are browner than in microdactylus, 

 and the lower one is not exactly at the fissure, but rather below it; 

 the most striking difference, however, is in the dark grey fringe in the 

 upper wings of scarodactylus, contrasted with the pale brown fringes 

 in microdactylies. 



9 Aciptiltjs (Hiibner). 



Antennae finely ciliated, with the basal joint thickened. Forehead obtuse, the 

 feathers forming no conical eminence. Palpi rather shorter than the head, slender, 

 pointed, the last joint bending downwards. All the tibise slender, and not thickened, 

 the spines of the posterior tibia? unequal. Anterior wings cleft almost to the 

 middle of their length, the segments of all the wings slender, linear, and evidently 

 without angles. Inner margin not toothed, the 3rd segment of the posterior wings 

 without black scales in the fringe. Anterior wings flat, with the margins only 

 very slightly deflexed. Veins of the anterior wings five in number, simple ; the 

 1st to the 3rd arising from the base and running to the posterior segment, the 4th 

 and 5th also springing from the base and going to the anterior segment. The 1st, 

 2nd and 5th veins more slender than the others. The veins of the posterior wings 

 are four ; the 1st from the base into the first segment, the 2nd from the base into 

 the middle segment, and the 3rd and 4th from the base into the third segment. 

 The 3rd and 4th veins are more slender ; the 2nd sometimes sends off a very fine 

 branch towards the first fissure. Cells of the wings, none. 



The Scandinavian species of this genus are only two, namely, 

 Aciptilus tetradactylus and A. pentadactylus. The larva of tetradactylus 

 is said to feed on Thymus serpyllum, in May and June. In Britain, 

 we fortunately have several more of this genus, viz., A. galactodactylus, 

 A. spilodactylus, A. baliodactylus, A. tetradactylus, and A. pentadactylus. 

 J?aludum certainly does not belong to it, the much longer palpi and the 

 slightly thickened tibise would be quite enough to distinguish it. 

 The only insect known to me in this group as likely to pass in our 

 cabinets undetected is xanthodactylus , which might be overlooked as a 

 variety of baliodactylus. It may be known by its having a spot on the 

 inner margin of the anterior wing, opposite the one on the outer 

 margin, as well as a spot at the fissure.
