Platagrotis pressa Git.

ic # * * The middle and hind tibiic are spinosc. The antenna? sim- 

 ple, scaled above, and setose beneath, not brushlike in the male. Tiie 

 color is a dusky gvny, and the species shows an aflinity with J'J. lierlmla 

 Iprasina] by the primaries being more or less shaded with green, 

 principally from the base outwardly over the renifonu, and along the 

 submedian interspace. Orbicular large, round, oblique, black ringed, 

 with pale center and au internal anuulus ; the discal space around the 

 spot and before the reniform is more or less noticeably filled in with 

 black, lleniform also pale, with fainter internal ringlets, black ringed, 

 well sized. The transverse lines are obsoletely geminate, filled in with 

 white and this filling in rather strikes tl»e eye and seems to be char- 

 acteristic. The clavilorm is large, its upper black edge appears as a 

 black arcuate line below the median vein, its lower edge is indistinct. 

 The subterminal line is more or less obviously preceded by black 

 shade dashes, usually determinate in pairs on submedian fold, between 

 veins 4 and and again subcostally; a dentate black terminal line 

 defines the uneven margin of the wing; fringes gniy. Bind wings 

 very pale, shaded with fuscous terminally, with an irregular faint 

 median fuscous line and black terminal linear edging; fringes whitish. 

 Beneath very pale, snbirrorate and shaded with fuscous, with a com- 

 mon line and discal marks. Palpi with the terminal joint white, the 

 second black on the sides. Head whitish; thorax mixed with black. 

 Abdomen weak, untufted." 



Exi)ands 34-30""".; 1.30-1.44 inches. 



Habitat. — Canada, Northern, Eastern and Western States. This 

 species, though widely distributed, is not common, single specimens 

 only being received. The differences separating it from spcciosa have 

 been already pointed out; the smaller size and paler color are the most 

 obvious features. 



Platagrotis trabalis Git. 

 1877. Grt., Cuu. Eut.. ix, l'.)8, Aijrotis. 



"Whitish gray, with large stigmata and bright bro^\n contrasting 

 subterminal space. A basal black dash, a second above it on the cell, 

 before the orbicular, which latter is near the t. a. line, inaugurated 

 above it on costa by two black lines rather wide apart, with white in- 

 cluded space. Below the t. a. line is twice waved to internal margin. 

 Basal space whitish; basal line indicated. Sub-basal space dark gray.
