HEMILEUCA NORBA Druce. 

 Plate LII, fig. 10. 



Imago. — Two $ . Head rather narrow, the front triangular, narrowing almost to a point 

 in front, rust-red. Palpi not distinguishable from the front. Thorax clothed with rosy and 

 gray hairs, the latter predominating, but red at the base of the second pair of wings. 



Fore wings very short and broad, more so than in olivise or any other species seen by me; 

 outer edge not oblique; wings of both pairs of a uniform peculiar pearly pale mouse-gray hue 

 and semitranslucent, thinner than in olivise. Veins ocher yellow and very distinct; costa of 

 fore wings also ocher-yellow ; the fringe concolorous with the wings. Fore wings crossed by 

 two distinct white lines of equal width and parallel, the inner (basal) running close to or touching 

 the discal spot, which is a very faint pale line, less distinct than in olivise, and much less so 

 than in tricolor; extradiscal line a little nearer the outer edge of the wing than to the discal 

 line; it begins on the inner edge nearer the inner angle of the wing than in olivise, and does 

 not end on the costa so near the apex as in tricolor. Hind wings with a single whitish extra- 

 discal line, nearly obsolete in one s ; it runs parallel with the outer edge of the wing. 



Under side of fore wings roseate on the inner two-thirds, the costa and outer edge being 

 ocherous, the roseate hue extends out between the veins toward the outer edge of the wing. 

 The linear discal mark is repeated beneath. In one s the wings beneath are less roseate and 

 the under side of the hind wings is nearly as above. 



Abdomen rust reddish above, beneath carmine red, with pale gray hairs on the side. 

 It is a very distinct species, and may be recognized by its pearly gray color and the two 

 distinct white parellel lines on the fore wings. 

 Expanse of fore wings, <? 48-53 mm. 

 Length of fore wing, S 24-26 mm. 

 Breadth of fore wing, j 14-15 mm. 

 Length of hind wing, i 20-22 mm. 

 Breadth of hind wing, S 15-16 mm. 

 [Described by Druce from a male collected at Amecameca, State of Morelos, Mexico.] 



HEMILEUCA MINETTE Dyar. 

 Plate LXII, fig. 12. 



[Front of head ocher, sides and behind crimson, thorax gray, abdomen dark red. Fore 

 wing dark gray, the veins and costa dark ocher, fringe and inner margin pale; lines somewhat 

 approximate, whitish, distinct, approximately parallel to outer margin, the outer wavy crenu- 

 late; discal mark a large, white, diffused patch, bare of scales centrally. Hind wing gray, a 

 whitish ray through the cell, a broad, distinct, outer whitish band; fringe pale, veins lined 

 with dark ocher. Beneath the ocher markings are broadened, but the lines of fore wing nearly 

 obsolete. Discal mark and submarginal band of hind wing distinct; base of fore wing shaded 

 with crimson. Expanse 40 mm. 



One male, Mexico, without definite locality (Schaus collection), probably from near Mexico 

 City. 



Type. — No. 12931, United States National Museum. 



This species, together with the norba and rubridorsa, may prove to be varieties of one species. 

 All apparently come from the high Mexican plateau in the vicinity of Mexico City. A large 

 series of specimens is needed to decide the matter. — Dyar, t. c] 



HEMILEUCA MANIA Druce. 



[Euleucophxus mania Druce, Biol. Cent.-Am., Lep. Het., II, 420, 1897. 



Described from Orizaba, Mexico. I have specimens from this place (Schaus collection) 

 and from Motzorongo (R. Miiller), both localities in the State of Vera Cruz, in the hot, moist
