HESPERIDI: THANAOS LUCILIUS. 1459 



Antennae blackish brown, very minutely flecked with whitish at the base of the joints 

 on the apical half of the stalk above ; and below distinctly marked with snowy white 

 at the base of all the joints, posteriorly extending upon the club, where it forms a 

 long field growing dirty yellowish toward the tip, the division of the joints faintly 

 marked with dusky; the anterior surface of the club naked and deep castaneous, 

 sometimes deeply infuscated above; the apical joint luteo-castaueous. Tongue 

 blackish fuscous, becoming castaneous apically, and at extreme tip changing to 

 luteous. 



Thorax covered above with blackish brown hairs and scales tinged with purplish ; 

 beneath with dark, slightly olivaceous, brown hairs, often ashy. Legs dark purplish 

 brown, darkest on upper surface of femora and tibiae, the sides of femora and under 

 surface of tibiae often tinged more or less conspicuously with silvery gray or dirty 

 yellow, nearly always with some shade paler than the upper surface, the inner sides 

 of the tarsi, especially toward the base of the joints, and the under surface toward the 

 base cinereous. Spurs dark brown, sometimes flecked with gray next the leg, reddish 

 tipped ; spines bright reddish luteous. Claws the same, dusky edged and tipped. Pad 

 dusky or blackish. 



Wings above. Fore toings dark grayish or cinereous brown, a very little darker in the 

 ^ than in the ? , heavily marked with black or blackish blotches and bands. The cell- 

 ular vitreous spot just beneath the base of the second superior subcostal nervule is seldom 

 present in the (J and often absent from the $ ; in the latter only is it ever as large 

 as the other spots ; these form a bent or curving broken series composed of subcostal 

 and median spots, none being ever present in the interspaces beyond the cell; the 

 subcostal spots are placed in succeeding interspaces below the second superior sub- 

 costal nervule in a nearly or quite straight line running from the costal margin, 

 scarcely within a point midway between the tip of the costal fold of the $ and the 

 tip of the wing, to the middle or just below the middle of the outer margin ; they are 

 four in number, although all but the second from above may become obsolete and 

 they are always minute, especially in the <? ; occasionally both and very often the 

 lower of the median spots are absent, especially in the (J ; the upper is placed just 

 before the middle of the upper median interspace, and the lower, when present, is 

 almost invariably farther from the border than the upper but not more so than in T. 

 persius. The basal half of the wing above the lower median nervule and the basal third 

 or two-fifths below it is heavily clouded with black, more or less blotched iu the lower 

 half of the wing with dark cinereous ; the outer limit of this field is more distinctly marked 

 in the ? than in the ^ and, starting from the tip of the costal nervure, is at nearly right 

 angles to the costal border, as far as the lower median nervule, below it arcuate, open- 

 ing outward. Beyond, the decided cinereous tint of the wing is more manifest, often 

 tinged to a very slight degree, especially In the ? , with purple; in the upper half of 

 the wing and sometimes toward the outer border (especially in the ? ) the gray tint is 

 more distinct than within the lower half of the extra-mesial band ; especially is this the 

 case between the cellular, ochreous spot and the outer series of similar markings, 

 where the whole roundish space from close to the costal edge to the bottom of the 

 cell is occupied by a distinct gray flecking, forming, generally, with the darker mark- 

 ings bordering it, a more conspicuous contrast than occurs elsewhere on the wing; in 

 the upper half it is often powdered slightly with whitish or lilaceous scales ; the extra- 

 mesial band is sometimes narrow, sometimes moderately broad, in the former case com- 

 posed of rounded triangles, in the latter of lanceolate dashes, pointed outward; it is of 

 uniform width, generally regularly arcuate, occasionally bent near the bottom of the 

 submedian area and encloses at its edge above, in its middle or the middle of its inner 

 half below, the subcostal and median vitreous spots ; the spots of the band are nar- 

 rowly bordered externally with pale cinereous markings, often flecked, at least in the 

 upper half of the wing, with hoary scales, which sometimes extend over the whole 

 outer border excepting the submarginal spots ; the latter are dusky, roundish, often 

 lunulate below, usually at least partially confluent, increasing slightly in size and 

 scarcely receding from the outer border in passing downward ; they are generally fol-
