outlined in black-brown, whereas in the type form it is absent; the shape and 
position of the orbicular very variable, in general large, obliquely oval, with 
rather ragged edges; the course of the ordinary lines as in the type form. Ex- 
panse 45-49 mm.

We consider this a Western race of the well known Eastern 
species; we have made three or four slides of the ¢ genitalia of each 
species and note the following slight distinctions; in the Western form 
the apex of the uncus is distinctly more spatulate than in lignicolora; 
the gnathium (scaphium) is much reduced, being short and semiquad- 
rate, whereas in lignicolora it is long and pointed; the apical lobe of 
the valves or claspers is smaller and slightly differently shaped in the 
western form and there are several slighter points of detail which can 
be better seen than described. Smith’s figure (Proc. U. S. Nat. Mus, 
XIII, Pl. XXXVII, Fig. 29) gives a general idea of the shape of the 
clasper and harpe. The species was figured in Vol. II, No. 1 of our 
Contributions. 
We have before us another form from Vancouver Is. which 
shows distinctions in both coloration and @ genitalia sufficient in our 
opinion to warrant it being considered a good species. The ¢ clasp- 
ers are much broader at the base than in either lignicolora or atriclava; 
the uncus apex is as in atriclava, but the gnathium much as in ligni- 
colora; the lateral portions of the tegumen are broader and the apical 
portion of same, bearing the hair pencil, much less sharply pointed ; 
we propose the following name: 
PARASTICHTIS PURPURISSATA Sp. Nov. 
Primaries deep purple-brown, washed in subterminal area, in @ slightly, 
in @ more strongly, with whitish, much as in auranticolor Grt. Mark- 
ings as in atriclava. Expanse 45-48 mm. 
Hazirat. Duncan, Vance. Is., B. C. (Hanham) 3 6, 3 9. Types, Coll.

The species is easily recognized by its deep purple brown color; it 
appears to be rarer than atriclava, of which we have numerous speci- 
mens besides the types; breeding will be necessary to prove the exact 
relation of these two forms; it was also figured in Vol. II, No. 1 of the 
Contributions.
