2. Lepisesia clarkiae Bdv. Quite common in the valley in early June, 

 1903, feeding at the flowers of Brodiaea, Rhododendron and Asclepias. 

 The insect (which flies shortly before noon until late afternoon) is 

 evidently in full season in May, but flies in March in Marin County. 

 Specimens from the latter place are much more difficult to capture than 

 the Shasta specimens, which average smaller in size and are of a 

 greener color. The eggs are laid upon the leaves of Clarkia, Godctia 

 and Epilobium sp. The larva, which has no anal horn, is pale greenish 

 in the first three instars and brownish in the last, being darkest on
