(from H.-S.) 
Time of Appeaeance. — June. 
Habitat. — Mountains in Candia. This remarkable insular 
species has as yet only been found in the above island, receiving 
its name from the Psiloriti Mountains (the ancient range of 
Mount Ida), on which it occurs at a considerable elevation. It 
seems to me possible that it is a local variety of some other form, 
perhaps of L. Astrarche.
