Euphilotes bernardino Coastal seg. - Undescribed blue on Eriogonum cinereum.

• Ken D. mentions two populations of undescribed Silvery Blues: one on the So. Sierra west slope, and the other SE of the Sierras.
• Gordon Pratt has discussed Euphilotes enoptes complex butterflies from the Big Bear region, inc. a multiple-brooded entity at Baldwin Lake on E. kennedyi and a rare Arrastre Creek blue on E. davidsonii that doesn't fly most years.
• According to John Emmel, the Arrowhead Blue I found north of Big Bear is Glaucopsyche piasus nr. sagittigera. It uses Lupinus andersonii as larval host.
Icaricia saepiolus aureolus and Philotes sonorensis extinctus are extinct.
