276 BIA. By G. Wbyjiee. 



(ricordaius. P. tricordatus Hew. (Corades t.). Forewing with 2 fine points in the anterior part of the distal margin, 



its posterior part obtusely dentate; anterior part of the hindwing also obtusely dentate, only the 3 median 

 veins having long points, that of the first median projecting furthest. Above broAvn, distally lighter, the 

 margins dark brown, forewing with white costal spot, hindwing with a submarginal row of black spots. 

 Forewing beneath red-broA\ti, striated with light yellow, the forewing at apex and the hindwing dark brown 

 with white striation. The latter Avith several Avhite spots, black margin and black submarginal band. From 

 Mapiri and the Illimani, Bolivia. 

 callipolis. P. callipolis Hew. (Corades c.) (60 d). The teeth of the distal margin are not so pointed as in tricordatus. 



Above brown with dark margin. Forewing with a lighter brown submarginal band, proximally bordered 

 by a dark brown dentate stripe, similar to that shoAvn in the figure of the under surface in the middle 

 of the forewing. From Bolivia (Illimani). For callipolis Stgr. cf. supra, p. 275, under C. dytnantis. 

 anforfas. P. anfortas Thienie is larger than callipolis, the teeth of the hindwing longer. The ground-colour 



of the upper surface is cedar-wood brown. Basal area and distal margin of both wings dark brown. Beyond 

 the middle of the wing is placed a row of dark brown spots, on the forewing elongate, on the hindwing round. 

 In addition on the forewing 2 elongate spots in the cell and 2 round ones before the apex. Forewing beneath 

 brown with silvery brown submarginal macular band, its proximal edge dentate. Hindwing beneath with 

 brown discal band, before this a silvery half-band and distally a partly silvery, partly brown-dusted submarginal 

 band. From Cuzco in Peru. Rare. 



58. Genus: ISia Hiibn. 



An isolated genus, possessing various peculiarities. Palpus moderately long, thinly haired, the ter- 

 minal joint thin and pointed. Eyes naked. Forewing with the costal and distal margins rounded. Hindwuag 

 produced at the inner angle into a point which projects far posteriorly and is placed on the first median vein. 

 In the forewing the costal vein is strongly inflated at the base, the median and submedian less swollen. 

 The cell of the forewing is longer at its posterior than at its anterior margin. On the hindwing there are two 

 hair- tufts (scent-organs) m the (J3^. One is placed in the inner-margmal fold and is composed of ochre-yellow 

 hairs about 3 mm. in length, which may be erect and diverging or again convergent. The other, at the anterior 

 margin of the cell, consists of short, erect, dark brown scales, which are partly covered by long, smoothly appressed, 

 lighter brown and yellowish grey hairs. Inhabits Surinam and the whole Amazon region as far as Peru. 

 adorion. B. actorioti L. (60 e). The bright iridescent blue spot at the inner margin of the forewing in the c^cj 



varies in size, in single examples from the Upper Amazon it occupies almost the whole distal margin, in others 

 it is very small or entirely disappeare. In the $ on the other hand the whole basal half of the forewing 

 nearly to the costal margin is bright iridescent blue. Under surface red-brown, densely covered almost 

 all over with fine light brown or yellowish brown undulate lines. Below the apex of the forewing 

 close to the distal margin is placed a small black ocellus with blue pupil. From Cayenne, Para and the 

 decaerulea. whole Amazon region. The form decaerulea Stgr. i. I. (60 e) shows no trace of blue reflection, on the other 

 atalanttt. hand the brownish yellow band is somewhat broader. It occui-s among the type-form. — atalanta Rebel (60 e), 

 on the contrary, has on the hindwing a very bright dark blue reflection, occupying nearly all the posterior 

 half of the wing. The forewing is without reflection and the brownish yellow band is very narrow. The 

 under surface as in actorion. Peru.

theodori. P."l*S2. Ailtirrhaea theodori Friihst. is a form of philaretes only described in the female, in which, 



mstead of the 4t blue spots Avhich philaretes $ has on the upperside of the hmdwing, only 2 are present, and these 

 are pale grey. The under surface is exactly as in philaretes. From the Upper Waupes (North Brazil). — A.

P. 183. Sinarisia adoptiva Weym. The $ of this species has been found by Fassl likeAvise in the 

 Colombian West Cordilleras, in the Rio Aguaca Valley, at 2000 m. It is but little larger than the <$, but, like 

 the $9 of Ant. geryon and geryonides, has broader wings, so that the apex of the hindwing is obtusely rectan- 

 gular. The point of the tail directed more distall3^ The ground-colour is somewhat lighter brown, the eye- 

 spots of the forewing are larger, have thicker Avhite pupils andre.i;f. bordered by obscure red-brown rings. 

 At the costal margin there is further a fourth, small, pupilled ocellus. The under surface is red-brown with 

 a broad band, striated Avith dark broAvn, across the middle of both Avings. In the distal area 4 white dots on the 

 forewmg and one on the hindAAing.
