5A REVISION OF THE DICOPINZ—SMITH. 
vergent, giving the insect a plump, more bombycid habitus, emphasized 
by the more broadly pectinated male antenne. The wings are rusty 
red brown or carneous gray, and powdery, so as to make them appear 
thinly sealed. 
Although I know autoptically all save one of the species in this series 
(viridescens W1k.), I have not given the sexual characters, partly because 
I have not had sufficient material of some species, and partly also be- 
cause the characters in the forms examined are so simple as to be of 
little or no value in the separation of the species. In all there is a 
simple oblong harpe, near the center of which there is a small, corneous 
beak-like clasper. 
None of the species are really common, and of those of which I have 
dates of capture all make their appearance very early in the season— 
a fact that may explain their rarity because they have disappeared 
when collecting usually begins. Mr. Grote makes the statement that 
they hibernate in the Chrysalis state.

In this genus the thorax is square, the patagie rather sharply de- 
fined, the primaries with the apices more marked. The character of 
the frontal vestiture has been already noted. 
Three species, grotei, muralis, and thaxterianus are referable here, 
Grotei is a dark, blackish gray Species, with squammose or roughly 
clothed wings, the markings indefinite, the reniform usually white and 
contrasting, the s. t. space concolorous in all the Specimens I have 
seen. 
This species was first described as a Valeria by Mr. Morrison, a 
genus of which Ihave seen no American Species as yet. I ealled at- 
tention to the erroneous reference in my Synopsis of noctuid genera, 
and Mr. Grote suggested the term Copivaleria for the species, distin- 
guishing it by the longer, more pointed, wings from Dicopis. The dif. 
ference however does not exist, and I can find no safe points for dis- 
tinguishing the genus. 
Muralis is smaller, varying from a rather light ash to dark black- 
ish gray, never as deep as in the preceding. The maculation is always 
traceable, and sometimes sharply defined. The reniform is large, bet- 
ter defined, and not so contrasting as in grotei. The s. t. space is 
usually more or less white, prominently interrupted in the submedian 
interspace by a black streak, which is often connected through the 
median space with the prominent basal dash. 
Thaxterianus is the smallest of the Species, in type of maculation like 
muralis, but quite evenly brown to the t. p. line, beyond which the ter-
