Morsea ealifornica dumicola' new subspecies (Plate XIl, figs. 3, 7 and 

 13; XIII, fig. 3). 



This more eastern race differs from typical Morsea ealifornica 

 in both sexes in the proportionately narrower, but more regularly 

 rounded, basal outline of the eye, in the less projecting fastigium, 

 in the more clavate distal section of the antennae, which in the 

 two forms are of about equal length, in the more robust and less 

 slender limbs and in the more abbreviate caudal tarsi; in the 

 female sex in addition, in the shorter and broader fastigium. par-
