t. p. line opposite the cell ami niwil angle. Tin- orhieulnr is elongate, pointed, 

 slightly (lefinefl ; the reniforin is a dusky, lunate spot. 



The type locality is Sierra Nevada, California, and the species is rare; most 

 of those standing under that name in collections being erroneously determined. 

 There arc none in my collection. 



The larva- is said to feed on poplar. 



Acronycta frigida Sm. 



Similar to felina in general type of maeulation, but decidedly blue gray in 

 ground, with all the mnculation represented more clearly and cleanly marked. 

 The t. n. line is at least indicated and the t. p. line is obvious throughout. The 

 basal black streak is obvious and there is a line of black scales in continuance, 

 joining it to the black streak crossing the t. )). line, which latter streak continues 

 across the terminal space to margin above anal angle. The black dasli crossing 

 the t. p. line op])Osite the c<'ll is ei|ually distinct, and both orbicular and reniforin 

 are well marked. 



The type localities arc Truckee and Sii-rra Nevada, California, and the 

 species seems to be rare. The larvii- is said to feed on willow. 



Acronycta cyanescens Ilamps. 



Resembles frii;i({a so closely that I had considered it identical. It is, how- 

 ever, much more |)owdery and obscure, the markings diffuse and ill-defined, the 

 •laggers crossing the t. p. line less obvious, the orbicular wanting. I am inclined 

 to consider the latter character variable, and ([uite expect that well marked 

 examples will have this mark at least traceable. 



The type locality is \'ancoiiviT, and my own single exainpli- is from \'ietoria. 

 British Columbia; but I have little doubt that the species will !«• found to extend 

 down the coast, and into California along the mountain ranges. 



Acronycta pacifica Sni. 



Rather a sni;iller and more fully marked species than the three just preceding. 

 The ground color is pale, but the surface is densely black powderi'd and the veins 

 are black marked, so that the insect has a strigate appearance, which is especially 

 marked beyond the t. p. line. The basal streak terminates at the t. a. line and has 

 an obvious ti-ndency to fork, as jn the more eastern Cindrrclla. Both dagger marks 

 crossing the t. p. line are obvious but no conspicuous, and both orbicular and 

 reniforni are present. 



The type locality is Sierra Nevada. California, and besidi-s the types I know 

 of no other examples nt present. 



Acronycta mansueta Sm. 

 This is a smaller, broader-winged species than any of the preceding, the 

 ground color of a smooth, even, pale blue gray. .-Ml the ordinary lines and marks 

 are obvious, but not contrasting, the distinctive feature being the broad, blackish 

 sh.ading along the inner margin. This extends from base to outer margin, but is 

 broken before the t. p. line. It is quite similar to falcula in general type of
