PLATYPTILUS. 3 



Hind wings and cilia rather pale brownish fuscous. 

 The legs rather shining brownish grey ; the third 



pair armed, as in C. festaliella, with moderately 



long spurs of the same colour. 



Expanse 9 millims. 



The small, green, and slightly hairy larvae were 

 found feeding (April 16th), in Northern Oregon, on 

 a species of Orthocarpus, and again, on another 

 species of the same plant, at the end of June, near 

 Eureka, in Humboldt County, California. Three 

 specimens bred from the former emerged at the 

 beginning of May, and one specimen from the latter 

 on the 10th of July. 



The larva appeared to draw together the slender 

 leaves at the terminal shoots of the food-plant, and 

 constructed a white open network cocoon, in which 

 the pupa was distinctly visible.
