Lenirth of body, 0.40; of fore wing, 0.55 inch. Length of Californian 

 example also 0.55 inch, but the wing is narrower. 



The distribution of this species in the Old World is thus given by Stau- 

 dinger: Saxony and mountainous parts of Silesia; Alps; Austria; Switzer- 

 land; Piedmont; England; Iceland; Lapland; Finland; and Livonia. 



Larva. — " The Lev. Joseph Greene has reared this moth from the egg, 

 which was hatched in June. The young caterpillars fed on groundsel during 

 the autumn; they grew very slowly; before winter they left off eating alto- 

 gether, but in early spring again ate the groundsel, and were full-fed before 

 the end of March. The caterpillar, when full-fed, is an inch in length; the 

 ground-color dull green or brown, but very variable ; the segments pink or 

 flesh-colored; the body is slightly sprinkled with black dots, with two very 

 distinct blotches on the sixth and seventh segments, the latter being the 

 largest. It spins up in moss, and turns to a brown chrysalis." — Newman's 

 British Moths, 168.

."> $ and 3 9. — Allied closely to O.munitaria in the form of the wings, 

 and in its style of coloration. The wings are almost subfalcate, and the 

 antennae, which are pectinated to the tip, arc more strongly pectinated than 

 in O. munitaria, the branches being as long as the head is broad on the vertex.
