HESPERIDI: TIIANAOS JUVEXALIS. 1477 



patch beliiiul the black tuft outside of the anteiiiiiie. Palpi firay, from a nearly e(|ual 

 miiigling of dirty white mid brown scales, the latter longer and often more abundant 

 than the other, especially toward the tip, and accompanied by blackish hairs, which 

 are more frequent along the onter anterior edge; the palpi are always darker above 

 than beneath, and the terminal joint darkest of all and uniform, seldom with any 

 intermingling of pale scales. Antennae very dark brown, sometimes almost black, 

 witli a slight purplish gloss, the tips of the joints on the apical half of the stiilk with 

 faint and narrow pale ainiulations above, distinct, white and broader below, especially 

 anteriorly, and extending over the whole stalk ; posteriorly the anunlations are a little 

 duller, are tinged with nacreous, which extends over most of each joint, increasingly 

 so toward the club, and there forms a continuous, very pale buff or silvery white 

 streak; club beneath naked and dark castaneous next the white portion, but else- 

 where obfuscated, often blackish. Tongue blackish fuscous, becoming luteous at tip. 



Thorax covered with nearly uniform dark brown SQales, below slightly paler than 

 above, and occasion.ally tinged with imrplish. Legs gray brown, flecked with paler 

 scales beneath and within, even on the tarsi; the tibiae, especially the longer pairs, 

 darker above and tinged with purple; under surface of tarsi naked .ind reddish 

 luteous. Spurs gray brown, the apex reddish, black-tipped : spines reddish luteous; 

 claws dull reddish at base, dusky on apical half ; pad blackish. 



Above fore icings dark grayish brown, tending to pale gray brown, especially in the 

 $ , which is always paler than the male, and in a lesser degree to the outer half of the 

 wing of the $ . The whole wing in both sexes pretty uniformly and sparsely flecked 

 with whitish or very pale lilaceous, elongated scales and hairs, which give it a slightly 

 hoary appearance ; they are more abundant on the apical than the basal half of the 

 wing, and are absent from the dark spots of the wing, but sometimes accentuate these 

 by clustering around their edges. The wing is marked with blackish, blackish brown, 

 and dark brown and vitreo-silvery spots. The last arecoraposed of asinglespot in the 

 cell and a transverse series in the middle of the outer half of the wing ; the cellular 

 spot is round, usually of about the same size as the average of the others, seldom 

 larger and often reduced to a mere dot or a transverse streak ; it is situated in the 

 upper half of the cell, between the bases of the first and second superior subcostal 

 nervules, and is accompanied, very rarely in the $, usually in the $ , by a similar 

 smaller spot in the lower half of the cell, sometimes only semi-vitreous; the series in 

 the outer half of the wing, the spots of which are almost invariably larger in the ? 

 than in the <? , and only half of which are constant, consists : first, of an upper series 

 of four quadrate, usually elongate spots, one in each succeeding interspace below the 

 second superior subcostal nervule, the uppermost occasionally reduced to a dot or even, 

 very rarely, obsolete, the next, usually the longest, extending outward beyond the 

 others, the lowest almost always square, — the whole depending at about a right angle 

 from the middle of the outer two-fifths of the costal margin; second, of another 

 series of four spots, half in the median, half in the medio-submediau interspaces, both 

 of the latter almost always obsolete in the $ , the lower of them often absent in the $ ; 

 when all are present, they form a slightly curving row, opening outward, the lower 

 three in a nearly straight series parallel to the outer border, the outer border of the 

 lowest spot striking the middle of the outer half of the submedian nervure, the outer 

 limit of the uppermost spot in the centre of its interspace ; the lower of the median 

 spots is very rarely obsolete and only in the $ ; these spots are usually triangular and 

 nearly equiangular, the apex outward, or. especially in the $ , are sublunate, and in 

 both sexes are seldom smaller than the subcostal series. In the 2 the lower and occa- 

 sionally the upper of the two interspaces which intervene between these two series of 

 spots is occupied by a small spot or dot, never approaching the others in size, and 

 which connects the two sets into an arcuate series. The basal half of the wing is filled 

 with many not very large, inconspicuous, dark, cloudy, only occasionally blacki.sh 

 spots; they most frequently occur along an intra-mesial line from the cellular spot 

 — which is often edged with blackish, especially on the inner side — to the middle of the 

 basal two-thirds of the submedian nervure, and also midway between this and the
