AMERICAN LEPIDOPTERA, 333 



the ground color less sharp, the bands almost obsolete, faintly showing from above 

 and strongly marked only on inner edge near apex from costa to vein 6. Legs 

 smoky yellow. 



Brooklyn, N. Y. From Miss Helen Jackson, its discoverer, for 

 whom it is named. 



The type is a 9 , not in the best condition, and is so far as I know 

 unique. It was taken on a window, being attracted to light in the 

 thickly built up part of Brooklyn. I am suspicious that it may be 

 an accidental importation from the Tropics. It has some resemblance 

 to D. ahydata Guen. 



D. decorata n. sp.— Expands 35 mm. Palpi, front and antennae dark ocher 

 fuscous; thorax dark gray. Abdomen fuscous ocher, darker dorsally, becoming 

 black on posterior part of each segment: fore wings bright, clear, very light gray, 

 more or less overlaid with fuscous striations. the light color clearer on middle 

 space and just beyond outer lines; basal line black, geminate, strong posteriorly ; 

 middle line black at costa. a shading across wing: outer line heavy, black, gemi- 

 nate, angled in opposite directions, and so more broadly separated below costa; 

 marginal line black, broken ; hind wings fuscous gray, two indistinct outer fus- 

 cous lines, more definite at inner margin ; marginal line broken, black ; all wings 

 with lengthened black discal spots : hind wings slightly angulate at vein 4. 



Platte Canon, Colorado, from Dr. Barnes. 



D. rectifaNCia n. sp.— Expands 35 mm. Palpi and front fuscous gray ; 

 antennfe white, ringed with black; summit and thorax dull white, with a few 

 blackish scales. Wings broad, dull white, slightly fuscous tinged, granular ; outer 

 line alone evident, fine dark fuscous, angled subcostally on fore wings, then 

 straight across wing, parallel with margin, straight and faintly showing on hind 

 wing; margins with faint intervenular black points; beneath as above, more 

 glistening, lines wanting, discal spots of fore wings evident, black. 



Washington, from Prof. Riley, taken by Mr. Koebele. The single 

 specimen is a 9 • 



D. crsisSHta n. sp.— Expands 31 mm. Palpi ocher fuscous, front dark fus- 

 cous; thorax fuscous gray with a bluish tinge. Abdomen and all wings even 

 light fuscous, rather evenly peppered with dark fuscous scales, slightly thicker 

 on outer margin ; outer line very faintly suggested ; beneath same color, slightly 

 more broken. 



Colorado, from Prof. Gillette ; one female only. 



D. subalbaria n". sp.— Of the size and appearance of Deilinia erythemaria 

 Guen. under which name it is probably in collections. The fore wings are not so 

 rounded, have a more pointed apex, and are hardly so broad, but the reseml)lance 

 is very decided. The wings are a dull white, with scattered dark specks, and the 

 fore wings with an ochreous tinge on the anterior portion, especially towards 

 base; along costa. especially basally, the dark atoms are thicker; below as above. 

 The species is easily distinguished from Deilmia erythremaria by the antennpp of 

 the % , as the pectinations are short and clavate : also the subcostal fovea at base 

 of hind wings below is wanting. 

 Colorado.
