Beutenmiller in 1897 (Bull. Am. Mus. N. Hist. IX, 210) from 
information regarding Walker’s types received from Sir Geo. Hamp- 
son gives the following synonymy for plagiata Wlk. 
plagiata Wlk. 
atomaria Wilk. 
clintonit G. & R. 
Dyar’s list of N. Am. Lepidoptera (Bull. 52, U. S. N. M. p. 260, 
1892) adopts the following synonymy: 
achatina A. & S. 
parallela G. & R. 
var. tephra Hbn. 
obliquata G. & R. 
var. cinnamomea G. & R. 
leucophaea A. & S. 
var. basiflava Pack. 
var. atrivenosa Palin. 
var. manto Stkr. 
plagiata Wlk. 
atomaria WIk. 
clintonti G. & R. 
This arrangement stood without further alterations until I911 
when Dyar (Proc. Ent. Soc. Wash. XIII, 16) published a very useful 
paper on the species under this genus, dividing them into two groups, 
according as the larvae were known to feed on pine or deciduous trees ; 
he made no complete attempt at synonymy, but emphasized the fact 
that there were probably more good species present in N. America 
than had been recognized in his List of 1902. 
Our own studies of the group lead us to concur with this last state- 
ment of Dyar, and we are further of the opinion that several of the 
older species have been misidentified up to the present time, and that 
others must be omitted altogether from our list. In this latter cate- 
gory we include tephra Hbn. (Samml. Ex. Schm. I, Pl. 178) and 
plagiata Wik. (1855 Cat. Brit. Mus. IV, 799). The figure of tephra 
is totally unlike any N. American species we have ever seen, the differ- 
ence being especially marked in the secondaries of the ¢, which show 
in the figure a distinct waved black postmedian line followed by a dark 
terminal shade, and strongly checkered fringes, features unknown to 
us in N. Am. species of Olene. Either the figure must be regarded as 
very poor, or else the specimens must be taken to be non-American. 
We prefer the latter alternative as in the first case an absolute identifi- 
cation is impossible and far too much scope is given to the imagination
