Several localities. May and June. Likes to repose on Eriogonum, and is only to be found where some species of this genus is abundant. Probably the caterpillar feeds on the flower of this plant. This species is a very fine analogue of the L. Daphnis of Europe.

Alæ ♂ ris et ♀ næ superne fuscæ, a radice ultra medium pruina cærulea obtectæ, limbo tessellato. Alæ ♀ næ vitta marginali pallide fulvescenti instructæ.
Alæ subtus cinereæ, anticæ puncto duplici radicali, linea discoidali serieque punctorum necnon lunulis marginalibus instructæ; posticæ macula alba pro linea discoidali signatæ vittaque alba quæ occupat spatium inter seriem punctorum et lunulas marginales.
I possess a pair of this Lycæna, through the kindness of our celebrated entomologist, Mr. Lorquin, who caught the species in the higher Sierra Nevada.
8. L. Icarioides, Boisd.
May and June, Marin County.
9. L. Dædalus, Behr.
Icarioidi similis sed subtus, quæ puncta in Icarioide sunt rotundissima, in Dædalo sunt transverse producta, lineaque discoidalis alarum posticarum, quæ in Icarioide deest et pro qua macula alba subtriquetra militat, hac in specie linea transversa distinctissime nigra vindicatur.
The three specimens in my collection, I received through the kindness of Mr. Chas. Hoffman, of the Geological Survey, who collected them in the Alpine regions around the head waters of the Tuolumne River.
