It is not necessary to apologize for making known fragments of the insect fauna of the seabeach of Pacific North America. This fauna commands attention. Among its several aspects are (1) it is linear, extending several thousand kilometers from north to south, but being only a few hundred meters wide, (2) its species are all confined within the seabeach limits, and (3) it is a threatened fauna particularly in southern California where the habitat is being rapidly altered by man for purposes of industry, housing and recreation. P~eservation of specimens from this fauna and recording of observations on its ecology at this time seems of paramount importance. Description of the larva and ecological notes on Phalerh rotundata LeConte have been made (Moore, 1975), but no opportunity to attempt to rear specimens presented itself at that time. Since then, pupae have become available and are described below.
