always paler than the hiiiflwing, nearly always complete, as the last spot hnt one (between the two median 

 veins) is seldom entirely absent; the basal area is mostly well developed, but in the 9 often reduced; in the 

 latter case cell-stripe and cell-spot always remain very distinct; the upperside of the hindwing is always 

 brownisli orange. Beneatli the hindwing from the base to the apex of the cell and a postmedian cos- 

 tal patch are coloured like the proximal area of the forewing, the disc is washed-out brown and the 

 angled median band, which passes I'ound the apex of the cell and in thnlia and its allies is commonly strongly 

 developed, is only indicated and sometimes entirely absent, the distal margin is slightly darkened. According 

 to the colouring of the upper surface we differentiate: f. holochroa form, nov., discal band of the forewing holnchroa 

 scarcely paler orange than the hindwing; f. ochrolaenia form. nov.. discal band pale yellow, proximal Sivca, oehrottn 

 orange; f. anteas Dhl., discal band and proximal area ]iale yellow, hindwing orange. These colour-forms are anteas. 

 not local. .4. anteas is distributed from Guatemala to Colombia and eastwards to East Venezuela; there are also 

 2 examples before me from the island of Tobago. A. H. Fassl, who has bred anteas from the larva, has pre- 

 sented to the Tring Museum a blown larva and some pupa-cases. The larva is black above except for the 

 spines, the latter light at the base wth the exception of those on the prothorax, each spine on a dark 

 spot surrounded by a light circle, each segment with 2 or 3 light transverse lines, the thoracic segments 

 in this example so pressed together that tlieir markings cannot be seen; the bristles on the spines white, those 

 at and near the tips dark; the length of the spines is more than twice the distance between two spines on 

 the same segment. Pupa-cases chalk-white, anal end black, the black spines of the abdomen about as long 

 as the distance between two spines (on the same segment), the pattern of the abdomen consists of longitudi- 

 nal streaks, namely a subdorsal, a lateral, and a strong ventral double row; in addition to these 10 longi- 

 tudinal lines (in 5 pairs) the abdomen bears only some very small and not numerous spots. Larva and pupa 

 are quite different to those described on p. 371 (from limbafa). — In the Cordillera of Merida (Venezuela) 

 flies a form which will possibly prove to be a local race of anteas and which I therefore add here provision- 

 ally: f. straminosa form, nov., the light parts of the upper surface entirely pale yellow, the hindwing distally !<tramino>-a. 

 sometimes more or less extended brownish orange, the stripes of the proximal area of the forewing reduced 

 in breadth, occasionally for the most part suppressed, the black stripes of the hindwing on the whole stronger 

 than in anteas. Under surface paler yellowish grey than in anteas, the hindwing less" brown and the angular 

 median line on the whole more distinct. 



A. thalia L. (83 c). Underside of the hindwing usually without row of bristles in the cell. Wings tlmlht. 

 duller-coloured than in anteas f. ochrotaenia. which resembles thnlia, the veins dividing the basal area of the 

 forewing always broadly black, the black stripes on the upperside of the hindwing more stronglj' 

 developed, the discal ones all extending nearly to the cell, the cell-stripe strongly developed. The underside 

 of the hindwing on the whole darker than in fflw^eas, especially in the $. The discal band of the forewing always 

 interrupted, the last spot but one being absent or quite small. A ^ from Paramaribo is distinguished by 

 its colouring: ab. idiograplia ab. nov., on the upper surface the basal area very much reduced, the postmedian idiograptia. 

 spot of the cell scarcely indicated, hindwing brown-black, a cell-sti-ipe divided by a black longitudinal 

 streak, a discal band 4 to 5 mm. in breadth composed of stripes and a long, diffuse line in the abdominal 

 area, extending to the base, dirty orange. Beneath as above, but the basal area of the foreiving and the mark- 

 ings of the hindwing paler, the band of the hindwing posteriorly still more strongly suffused with black than 

 above. — Surinam and British Guiana. The larva is described and figured by Stoll as cinnamon-brown. 

 ^\■^th black lateral stripes and cinnamon-brown head. Pupa white, marked much as in A. anteas. 



A. cedestes. cj and $ without or (J with row of bristles in the cell on the luiderside of the hind- 

 wing. On an average larger than anteas and thalia; markings of the fore\\'ing pale straw-yellow; hind\\'ing with 

 the exception of the base commonly tinged with orange, the lower angle of the cell long-produced, so that 

 the base of the upper median vein is placed much more distally than the upper angle of the cell, above usually 

 entirely without blackish median band, under surface as in aniens shaded with blackish in the distal half, 

 especially near the lower angle of the cell, the median band indicated, but not sharply defined. Ecuador. 

 — suspecta suhsp. nov. ,^$: the basal area strongly suffused with black, washed out, the cell-spot, however, ^d-iyiccfa. 

 purer pale yellow. In western Ecuador; Paramba and Chirabo; in the type from Paramba (^) the hind\nng 

 without bristles in the cell on the underside and the disc above brownish orange. — cedestes Jord. (83 a), cedestes. 

 (J?: the basal area well developed, the postcellular stripe in particular sharply defined and broad. South-East 

 Ecuador: Zamora. 



A. terpsinoe. The largest species of the thalia group, except for stunted specimens. Wings broad, 

 especially the hindwing; on the underside of the hindwing the cell always without row of bristles and the 

 light costal patch sharply defined and more distal than in the preceding forms. Peru and Bolivia. The races 

 of terpsinoe. cede-^^tes, thalia and anteas replace one another geographically and are possibly forms of a single 

 species. — terpsinoe Fldr. ,^ : on the whole somewhat paler than crassinia (82 g), especially the basal area ierimnoc.

 Wings very broad, the discal band of the forewing mostly white, more rarely yellowish, its penultimate spot 

 seldom indicated ; the black stripes of the hindwing as a rule very short. Basal area of the forewing and the
