ruddy shading on both sides of the median wliitish area is very bright 

 pinkish whereas in those specimens of pluviata which show a ruddy 

 tinge the color is dull and more generally suffused over the entire 

 wing surface. The time of flight would appear to be somewhat 

 earlier ; the Catskill Mt. specimens were captured in late May whereas 

 pluvxata, which is common in the same locality, judging by a long 

 series before us from the Pearsall Collection, is at the height of its 

 flight in mid-June, continuing into July. Finally the Uncus of per- 

 fracta examined under the binocular shows a narrow neck of the 

 frigidata type with the forks distinctly divergent, whilst in plmiata 

 the neck is more of the cacnilata type showing scarcely any contraction, 

 with the lateral edges forming almost a straight line from apex of 

 forks to base of neck. These differences may or may not prove 

 specific when more material can be examined and life histories studied 

 but for the present no great harm is done by treating the two forms as 

 distinct species. 



We have two specimens from Vancouver Island, B. C. which 

 seem best treated as a race of this species and for which we propose 

 the name exasperata ; they are slightly smaller than typical pcrfracta 

 (28 mm.) and are more sharply marked, the cross-lines being heavy 

 and distinct; the whole of the primaries is evenly suffused with a 

 ruddy color giving the form a great similarity to californiata Pack, 

 from which it may at once be separated by the shape of the Uncus 

 (PI. VIII, Fig. 6) which is very similar to that of perfracta. the forks 

 being rather chunkier and somewhat shorter and the neck slightly 

 thicker. Our types are 2 i's, the one from Departure Bay, Vane. 

 Is. B. C. (July 13), the other from Wellington, B. C. (June 23) both 

 originally collected by Rev. G. W. Taylor. 



Hydriomena marinata sp. nov. (PI. VI, Fig. 6). 



Palpi moderate ; primaries olive-green whh a very faint ruddy tinge ; sub- 

 basal line black, in general oblique with a slight incurve in the submedian fold and 

 a faint angle at times on median vein ; band 2 broad, 

 irregular, bordered on each side by the green ground 

 color ; line 3 fine, dark, irregularly oblique ; median 

 area greenish, more or less dark shaded around cell 

 with a fine dark discal streak narrowed consider- 

 ably at inner margin; line 4 oblique at costa. angled 

 inwardly opposite cell followed by a strong outward 

 bulge, after which it is irregularly scalloped and 

 aia inwardly oblique to inner margin : outer area uni- 



colorous olivaceous crossed by the usual broad dark 

 subterminal band which is connected with apex of wing by a dark streak; dark
