34 [July. 
far as at present observed, it only occurs on one closely-sheltered 
bank, although its food {Lohis corniculatus) grows everywhere on 
the hill. The larva feeds at night on the flowers of the Lotus, pre- 
ferring them to the leaves, though it will eat the latter in confine- 
ment. On the Continent it is understood to feed exclusively on 
lichens, frequenting the roofs of houses and churches. Lichens of 
various sorts abound at Howth, but the larv89 do not appear to 
eat it. 
How this South European insect obtained a settlement on one point 
of the Irish Coast, and in no other part of the British Islands, is a 
curious problem in Natural History. The extreme sensitiveness of the 
larvse to cold, the slightest frost (in confinement) proving fatal, gives 
the idea of an insect not thoroughly acclimatized ; and it does not seem 
improbable that it has been introduced in the larva state among moss 
or lichen by some of the smugglers for which this part of the coast was 
formerly notorious, and for whose repression a numerous coast-guard 
is still maintained, as the entomologist who attempts to use a lantern on 
the cliffs of Howth will soon find to his cost. The moth appears early 
in August ; it flies for about half-an-hour at dusk, and again in the 
morning dawn. The males may be attracted abundantly by a bred 
female, and both sexes come freely to sugar.
