Wash., at an altitude of 6,000 feet. After a somewhat prolonged 

 search ten larvae and one pupa were collected, the latter being the 

 first found. 



The larva is distinctly a leaf roller, not invading the umbels as is 

 done so commonly by members of Agonopierix and Depressaria. The 

 pupa was found in an umbel, but there was no sign of feeding having 

 taken place, and I do not think it is the usual habit for pupation to 

 occur there. It seems more likely that pupation generally occurs 

 about the base of the plant in debris. This larva is one of the most 

 active in the group, being easily disturbed and very difficult to capture. 



Pupa : Normal for group : "Wing, antenna, and leg sheaths bright 

 green. Abdominal segments green heavily suffused with reddish pur- 

 ple dorsally. On the second day the color begins to deepen; the 

 sheaths become a duller and darker green and the abdominals a light 

 reddish brown. The color gradually becomes darker until the pupa 

 is almost black. 



The pupal period is lS-14 days. 



This species is very close to the European cilieUa and was identified 

 as such by Walsingham. The American rosaciUeJla has a much more 

 slanting termen and appears to be a more narrow-winged species than 

 cilieUa. The genitalia of the male of rosaciliella show a truncated 

 anellus, while in cilieUa the anellus is concave. The harpes of the 

 former species are less pointed and broader than those of the latter. 



The abdomen of the type is lost, but I do not hesitate to place the 

 reared series under this name. 



AGONOPTERIX ROSACILIELLA ECHINOPANICIS, new variety 



Similar to typical rosoxiilieUa but may be distinguished from it by 

 the generally lighter color and less suffused and less smoky appear- 

 ance. The black scaling is sparser and more sharply contrasted. 



The male and female genitalia are the same as those of typical 

 ros(wiliella.
