 bordered by red. Cluiana to the Amazon.

 duller blackish-brown, the hindwings exhibit in the proximal-marginal half towards the margin a large, lilac- 

 blue spot, in the anal lobe a small red spot. Beneath exactly as hesperitis (157 i), only of a somewhat more 

 lustrous, olive-yellowish tinge. Nicaragua, Colombia.

 steel-blue, with narrcnv blackish-brown margins. Beneath slightly lighter blackish-brown, the postdiscal line 

 on the hindwing more iiregularly broken, the submarginal lines nuicli nearer to the margin, the small anal 

 spots bordered by deep rcfl-brown. Guiana to South Peru. 



Th. vesper Drc. (158 a) is above deep metallic blue with rather broad black margins and behind the risi„r. 

 cell of the foiewing a black spot being connected with the costal margin; in some specimens the cell itself is 

 also black. Beneath very similarly marked to thama. but the ground-colour is a light ashy grey; on the hindwings 

 the postdiscal line is more angularly broken, not with such pointed angles as thcie; the anal spots are lighter 

 orange. Peru and Bolivia. 



Th. zurkvitzi Schs. may yet be appended here. Above quite brown with a red anal spot of the hindwing .mrkii/rji. 

 and a white marginal line analwards. Beneath lighter brown with a blackish marginal line: the postdiscal line 

 on the forewing is reddish-brown, distally black, then white-bordered, beneath the lower median vein displaced 

 inward, on the hindwings proximally brighter and broader red, running as in hesperitis (157 i); the submarginal 

 lunae darker brownish, on the hindwing.s bordered by whitish; the anal spots large, red; also above the spot 

 of the tail some red. Expanse of wings: 25 mm. Sao Paulo. 



93. Centoripa- Group. 



Th. centoripa Hew. (= hahneli Styr.) (158 a) looks above almo.st like xeneta (157 k), but the hindwings nuioriixi. 

 are more extensively blue. Beneath similarly blackish-brown, but very peculiarly marked: the postdiscal line 

 on the hindwing placed Cjuite into the centre, beginning at the costal margin with a large black spot and con- 

 taining the light discal streak in the middle of it; the W at the proximal angle distally bordered by white; the 

 anal spots in the darkened distal margin are black. Colombia, Peru, Amazon. 



94. Cecrops-tiroup (Calyeopl-i Seudd.). 



Th. cecrops F. (= poeas Hbn., beon Godf.) (158 b) is the northern representative of a difficultly cccrop.i. 

 separable group of small species of which a very great number is described that are surely partly coincident 

 as synonyms. The present species is either above ciuite dark-brown, or on the forewings towards the base and 

 on the hindwings in the inner-marginal half suffused with blue, in the $ more intensely. The hindwings exhibit 

 towards the proximal angle a fine black marginal line being proximally bordered by blue-white, and a small 

 red anal spot. The under surface is light-brown, the costal base of the forewing orange; both wings exhibit 

 fine, double, orange-red discal streaks, on the hindwings more distinct, both with broad, orange-red discal bands 

 on the forewings almost straight as far as the lower median vein, on the hindwings straight as far as the lower 

 radial vein, then broken and forming a W at the proximal angle, distally finely tinged in black, then white. 

 Distally follows the subterminal formed of blackish crescents, between the lower radial and the lower median 

 vein more intensely black, placed nearer to the postdiscal line, distally filled up with 2 orange crescents which 

 exhibit towards the margin high black triangular spots; then follows analwards a black spot densely strewn 

 with blue-white; the anal lobe itself is above bordered first by white, then by orange; a fine black marginal 

 line, proximally tinged in white. Everywhere common in the Southern States, West Virginia, Kentucky and 

 Indiana. — beon CV. (= isobeon Bflr.. bactra Heir., caulonia He.ir., vibulena Hew., bellera Hew., jeneirica Fldr.) ham. 

 (158 b) is distributed in the whole of Central and South America to South East Brazil and mostly common. 

 This form is above deeper blackish-bro«n, the hindwings in the ,^ more extensively and more metallic l>lue 

 in a rather variable extent; in the ^ tlic blue is mostly duller and lighter and is to be found also on the basal 

 inner-marginal half of the forewing. The ground-colour beneath is generally darker brown, the postdi.scal lines 

 very much narrower red and much deeper, almost scarlet-red, the black filling up of the t^o red spots of the 

 tail is much more reduced and does not reach as far as the marginal line, the space between them and the 

 anal spot is not so extensive and not so blue, but more strewn \\\i\\ greyish-white. 



Th. amplia Hew. ( 158 b) is above very similar, the blue is paiticularly in the '^' sonrewhat more whitish, amjilia. 

 not so ultraniarine-l)lue: beneath darker brown, on the forewings the proximal orange bordering of the po.st- 

 discal line is absent, on the hindwings the orange margiiuil lunae are proximally bright ochreous yellow or
