of which projects above the upper radial vein to the margin; on the hindwing there are before the fine black 

 marginal line small dark spots on the ends of the veins. Beneath the hindwing shows a rather broad black 

 marginal band which is interrupted by white below the upper radial vein; near the base there are yet some 

 dark diffuse spots. Mexico to Colombia and Brazil. — maimon Plotz (178 e) is probably a small, above entirely maimon. 

 white form of it from Guiana. 



H. macaira Beak. (= oceanus Ediv., locutia Hew.) (178 e) is smaller, above the same, beneath the macaira. 

 hindwing is smoked brownish except the anal part, the marginal band is not interrupted and distally extending 

 in a coppery brown, the basal spots are larger. Arizona to Panama. — f. jason Ehrm. i.s a pale, thinly jason. 

 scaled form from Veneziiela with beneath extinct basal markings, of a slender structure. 



H. cnemus G. <£• S. (178 e) is above much more intensely marked with broad blackLsh-brown cnemu-i. 

 margmal bands; in the broad apex of the forewing there are 4 or 5 small, narrow, white subapical .spots. Beneath 

 almost like nivella, but the apical part of the forewing is more broadly marked black, whereas the marginal 

 band of the hindwing is feebler. Only from Mexico. 



H. laviana Hew. (= leca 5<?>'.) (178 e) is mostly rather large with a faintly stunted, broadly blackened Javiana. 

 apex of the wing, with subapical, apical and marginal white spots. Beneath in the apex of the forewing 2 larger, 

 olive-brown spots. Hindwing more or less extensively dusted olive yellowish-grey, with a broad, dark, basal 

 transverse band which in the cell returns to the base in an acute angle, and a broadly darkened marginal part 

 proxmiallj' bordered by an almost straight, darker, inside white line extending from the costal angle to the 

 anal angle. The development of the marking, however, is very variable. Mexico to Argentina, everywhere 

 very common. — f. ericetorum Bsd. (178f) is a very light form from California. ericetorum. 



H. sublinea Schs. is unknown to me, but it apparently approximates laviana very much; distinguished suhlinea. 

 by a black cell-end streak and white fringes speckled with black, as well as more distinctly black veins in the 

 apical half also beneath. Hindwing of a purer white with a broad olive-grey marginal part, a dark apical 

 spot and a darker marginal band below the lower radial vein; the broad, proximal olive-grey band extends 

 from the costal margin to the lower median vein. Expanse of wings : 33 mm. Described from Mexico (Orizaba). 



H. purgia Schs. must be likewise similar to laviana (178 e); above marked just like it, but below the purgia. 

 lower radial vein there appears a larger, white marginal spot. Fringes dark grey. On the hindwing the veins 

 are partly black, beside a black marginal line and black marginal lunae there is a subterminal line interrupted 

 between the radial veins; base, and proximal margin of the hindwing dusted black. Fringes of hindwings white 

 speckled with black. Beneath marked light reddish-grej , forewing with a black cell-end streak ; hindwing 

 yellowish-white with black veins, a broader and darker subterminal band; the proximal band as in laviana, 

 the inner-marginal area remains broadly white, unmarked. Expanse of wings: 30 mm. Castro (Parana). 



H. pastor Fldr. (= omrina Btk.) (178 f). I consider to be a distinct species; smaller than laviana, pastor. 

 without traces of a stunted apex of the wing ; owing to the more distinctly marked veins the dark marginal 

 area looks striped. Marginal part of the hindwing more intensely marked. Beneath of a purer white, markings 

 in the marginal part likewise more radiately arranged and with a decidedly yellowish-green tint; basal band 

 feebler, in the middle interrupted. Guiana to Brazil. — In Bolivia there occurs a still much more intensely 

 marked form which I denominate intensa form. nov. (178 f). Above particularly on the hindwing in the costal intensa. 

 half there appears a postdiscal band angularly projecting distally and being also present beneath; the subbasal 

 band is deep olive-brown and complete. — f. pampina Ploiz (178 f) from Buenos Ayres, in contrast with it, is panipiHa 

 much lighter, above much more extensively white, and beneath on the hindwing only the basal band is rudi- 

 ment arily noticed. 



H. leucola Hew. ( 178 f ). I dare not decide whether this is a distinct species or only an intensely marked leucola. 

 form of petrus (178 d) from which it is not discernible above, whilst beneath the hindwing is of a more mtense 

 yellow colour with prominently black veins and internerval stripes, without any dark antemarginal spots. From 

 Minas Geraes. 



H. concinnata Mab. seems to be allied to laviana (178 e); distal margin of wings more intensely marked concinnafa. 

 black with small, white submarginal and very small marginal spots which are absent between the median veins. 

 On the hindwing beneath the upper part of the basal band is absent. Described from Rio Grande do Sul. 



H. figara Btlr. Wings above white, forewing at the base, costal margin, apes and distal margin brown; figam. 

 an apical, white oblique line is parted into 5 dots by the veins crossing it. Hindwing at the proximal and distal 

 margins brown, veins (except the base of the costa) black, fringes white speckled with brown. Body brown, head 

 and prothorax spotted white. Wings beneath white, veins in the distal half black; apex between the veins 

 white. Otherwise as above, but lighter. Body white. 1.6 inch. Exact patria not stated. 



61. Genus: Tliaiiaos Bsd. 



Rather closely allied to the preceding genus; the basal palpal joints are clad with long haii-, the conical 

 terminal joint is bent forward. Costal fold very strongly developed. Hindwing in the basal quarter of its costal
