HESPKRIDl: IIESPERIA CENTAUREAE. 1543 



Imago (15 : "i). Head covered above with pale greenish yellow ami brownish hairs, 

 the former more abiinilant on the hinder, the latter on the front half ; beneath very 

 pale straw yellow, with a narrow belt of the same encircling the eye, brighter in coftr 

 above and interrupted at tlie antennae, and again a little way behind them; tnft of 

 hairs ontside the antennae l)lack. Palpi white, very faintly tinged witli bluish yellow, 

 pretty profusely supplied, excoptingoii the sides, with long, delicate, black hairs, which 

 increase somewhat in abuntlance toward the tip, but there are as abundant below as 

 above; apical joint tjlackish l)rown, heavily supplied with yellowish beneath. Antennae 

 black or blackish brown, not so dark on the clul) and often tinged with yellowish 

 brown, all the joints, including tliose of the club, interrupted with white on the basal 

 third to half above ; beneath wholly yellowish nacreous, deepest in color on the club, 

 where it extends to the tip; apical half of the anterior portion of the club and the 

 whole of tlie terminal joint naked and dark castaueoiis. 



Thorax covered above witli pale, dull greenish brown hairs; beneath with pale 

 greenish yellow hairs, mingled with black ones on the coxae; iu front dirty white; 

 femora and tibiae l)lackish brown, very heavily tlecked with silvery white and nacreous 

 scales, the former fringed with long white hairs with a few intermingled black ones ; 

 hind tibiae of male with a spi'eading pencil of hairs longer than the tibiae, attached to 

 the inner side of the base; hind coxae with a pair of parallel, backward directed, ap- 

 parently cylindrical processes, as long as the tibiae and clothed with a mat of short 

 hairs; tarsi luteo-castaneous. heavily flecked aljove and on sides with white scales, 

 but mostly supplanted above, especially on the apical joints with brown. Spurs white 

 tipped with dark reddish; spines reddish luteous ; claws reddish. 



Wings above very dark gray brown, with a barely perceptible olivaceous tinge, 

 spotted with white. Fore tcin/js profusely furnished at the base with pretty long, 

 longitudinally directed, pale greenish gray hairs, which are also found very sparingly 

 on all other parts of the wing, decreasing in abundance toward the outer border; the 

 cell is marked at its extreme tip by a short, transverse line, and is crossed in the middle 

 of its outer two-fifths by a rather narrow, usually bent or arcuate bar, opening outward ; 

 above the latter is a short longitudinal dash in the interspace between the first and 

 second superior subcostal nervules and often a second above the upper of these ner- 

 vules ; a small spot, usually divided longitudinally in two, is found in the middle of the 

 basal three-fourths of the medio-subraedian interspace; near the middle of the outer 

 half of the wing is a narrow, very tortuous, transverse series of nine subequal spots; 

 it is composed of three portions : the upper consists of three rounded spots, gener- 

 ally longer than broad, depending at right angles from a point a little beyond the 

 middle of the outer half of the costal margin, separated from each other by the fourth 

 and llfth superior subcostal nervules; the middle series is a diagonal, nearly straight 

 but slightly curving series of more distant spots, of which the second from above is 

 smaller than the others and which lie in the succeeding interspaces, terminating at the 

 lowest median nervule. in the direction of a line drawn from the outer margin in the 

 middle of the upper of the two interspaces beyond tlie cell to the middle of the basal 

 two-thirds of the inner margin ; the lower series is parallel to the middle one and con- 

 sists of two spots, generally a little smaller than those directly above, in the raedio- 

 Bubmedian interspace, midway between the inner spots of sume interspace and the 

 outer border; the outer half of the costal edge is alternately and equally marked with 

 white and blackish, the former forming four dashes, of which the second before the 

 apex is directly above the extra-mesial series of spots; the outer border is sometimes 

 Indistinctly edged with black. Fringe whitish, interrupted conspicuously, but not very 

 broadly, at all the nervure tips with the color of the wing, often expanding a 

 little apically. Ilind icings more or less deeply marked with two arcuate series of 

 often obsolescent, always blurred, whitisii spots, the broader crossing the wing just 

 before the middle and scarcely discoverable on the lower half of the wing, the other 

 of a breadth similar to the extra-mesial series of the fore wing, midway between the 

 first and the outer border, approaching the latter slightly where it terminates below at 

 the submedian nervure; outer margin seldom edged with blackish; fringe as in fore 

 ■wings, but without any fau-liko expansion of the dark interruptions.
