NOTES ON CRAM BUS. 



BY A. R. GROTE. 



Crainbus sericbiellus Zeller. 



I am indebted to Professor Fernald for specimens of this species from 

 Maine. It appears in two forms ; one in which the thorax and fore wings 

 are pure satiny white, which, from Prof Zeller's description and a speci- 

 men sent him for identification, is the typical sej'icmellus ; the other, in 

 which the white is somewhat faded, having a sHght yellowish or fuscous 

 cast. This latter. Professor Fernald informs me, corresponds to Clemens' 

 type of inornatellus, a name which I have referred as a synonym in my 

 preliminary J.ist. It may be retained as a varietal name ; I do not think 

 it can be specifically distinct ; in some undoubted sericinellus the thorax 

 is a little soiled. 



Crainbus minimellus Robinson. 



I have identified this species from a specimen in my collection from 

 Massachusetts. It has very pointed fore wings, and the little species 

 seems to me related to the Leachellus group. 



Crainbus undatus Grote. 



This species belongs to the ejisiccatus group ; it is smaller than 

 exsiccatus, pale brown, the primaries washed with whitish, and having two 

 dotted transverse lines, angulated on the disc, continuous and very distinct, 

 not drawn in submedially. Fringes brown, with a silky or metaUic shade. 

 A fine series of terminal brown dots. Hind wings pale gray, with a faint 

 subterminal line, discontinued inferiorly, visible also beneath. We have 

 two Californian species, anceps and undatus, and two Eastern species, 

 exsiccatus and laciniellus, which are allied in having the fore wings crossed 

 by two brownish angulated uneven lines more or less continuous and 

 diftering in expression in each species. 



Crambus occidentalis Grote. 



Mr. Hy. Edwards considers this a distinct species and not a variety 

 of Leachellus. It differs by the prominent notch of the white stripe on its 

 lower edge at the middle, and by the dark shades accompanying the 

 stripe below. It is collected about San Francisco. What 1 regard as the
