lighter form, more common in Ariz., was (li_scribecl liy Mr Grote, Can. 

 Ent. Vol. XV, p. 27, and called /'. simpliciaria. iMr. Grote's T. ohlen- 

 larii (which must be T. oLhntaia) is close in appearance, but the cross 

 lines are much wider apart, the antennae of the (j^ are simple and the 

 palpi verv much less prominent. 1 have both his types b("fore me for

5. Tetracis cavillaria sp. nov. E.xpands 41 mm. Head, bdy and wings of 

 a dull lighl ochreous fawn color. The outer pari of ihe wings with the color a little 

 more decided, and over all a faint flesh colored flush. Lines faini, the t.a. nearly 

 straight, the I. p. nearer median than usual, present on both win,'s, dull fawn. 

 Another line beyond, faint, reaching from costa half way across fore wing. Beneath 

 as ab:)ve, soaiewhat lighter. Antenn;^ in ^ rather shorter and pectinations more 

 lengthy than usual. Fore wings slightly, hind wings very slightly angulated. I t^.

6. Tetracis morsicaria sp. nov. Expands 37 mm. Head, thorax and ab- 

 domen light ochreous, lines dark fawn edged t.a. line inwardly, t.p. line outwardly 

 with white. T.a. line straight, reaching twice as far out on costa as on inner margm. 

 T.p. line oblique, starting from costa just within apex. Hing wings very light ochre- 

 ous outwardly, nearly white inwardly. Beneath lighter than above, t.p. line alone 

 indistinctly evident. Margins of fore wings not falcate, but waved, fringes red. 



I 9- Te.Kas. Coll. Hulst. Very like in appearance to T.paral- 

 Itliaria var. siinpIuMria^ but the fore wings are much more extended, 

 both lines, especially the outer, more oblique. The outer margin of the 

 fore wing is much less falcate and angulated, and the margin itself is 

 wavy and edged with reddish. 



7. Tetracis trianguliferaria Pack. var. notataria var. nov. 



This variety differs from the type form in having just within the 

 posterior angle of the fore wings a dark brown spot, reaching from the 

 inner border to vein 4. It is undoubtedly a part of a band corresponding 

 with that of 7! coloradaria Grt. and Rob., but not connected with the 

 outer costal spot. 



8. Tetracis edwardsata Sp. nov. Expands 35 mm. Head, antennae, thorax 

 and abdomen cream white. Fore wings a light yellow ochre, crossed with a dark 

 tawny band which is edged on both sides with white shading into the ground color. 

 The band is broad at costa embracing one-third of the wing and reaching nearly to 

 apex, then narrowing runs with nearly parallel sides first outwardly, then inwardly, 

 and finally widens rapidly to inner margin. The outer margin of the wing is slightly 

 darker than the ground color. Hind wings very light in color, a little clouded out- 

 wardly, without band, and very slightly angulated at the middle. Fore wings angu- 

 lated, and slightly falcate. Beneath very light cinereous, satiny, unicolorous.
