718 PANDEMOS; STALACHTIS. By Dr. A. Seitz. 



cosMis. D. costalis Bat. Above greyish-brown, the forewings with 3 dark streaks in the cell and some ii-regular 



blackish markings; towards the border the colouring turns reddish. Hindwing with 6 dark lines, the 4th of 

 which is bent and interrupted. Under surface bluish-grey, the marking similar to that above. Teffe. 



95. Genus: Paiidenios. 



This genus, the 3 hitherto known species of which must yet be regarded as not fully ascertained with 

 respect to their homogeneousness, comprises only large and rare animals. One species, godmannii, is presumably 

 — anatomically it is not known — well attachable to the Tharops dealt with last; but I do not know the 9 which 

 may look quite differently and may approximate an Euryhia. The two other species are entirely unlike this 

 species as well as among each other. Head stout with large eyes and a medium-broad, flat forehead, palpi pro- 

 jecting but not very long, with a thin terminal stylus, wings differently shaped in each species, in the ^ of one 

 species with black scent-spots. 



godmannii. P. godtnannii Deiv. (128 k as godmani). Forewings similar to those of the $ of the preceding species, 



but the white costal diffuse spot extends as a small curved band almost to the anal angle and the ground-colour 

 is more red-brown than dark brown. The blue of the hindwing, which in Tharops superba is mostly covered 

 by black in the distal part, covers here the whole wing except the yellowish-brown inner-marginal stripe. Un- 

 doubtedly very rare. The figure according to the specimen in Godm.an's collection. Mexico. 



pasiphae. P, pasiphae Cr. (= arcos Cr., ormenus Hbn., perigone Godt.) (128 k). (J with a less falciform, but still 



pointed apex. Here also the forewing is dusted with a dull violettish blue except the blackish apical part. Where 

 the forewing and hindwing cover each other, there stands a black scent-spot. $ dull white with a bread dark 

 margin of the forewing, of the exterior of a Pieris orseis (18 f). (J (J from Guiana have a blacker upper surface, 

 those from the Rio Madeira a very bright blue one, and in 9$ from Colombia (Villavicencio) the border of the 

 forewing has but quite a faint dark shade. Guiana to Colombia, Amazon and Peru. 



palaeste. P. palaeste Hew. (128 k). (J above blackish-brown, the distal part of the hindwings with bluish-grey, 



salvafor. sometimes greenish-lustrous longitudinal spots. Colombia. — In the form from Costa Rica, saJvator Stick., 



the bluish-grey radiate spots extend towards the base as far as beyond the centre of the hindwing, and before 



the anal angle of the forewing is a red semi-band. The $ is not described. 



96. Genus: ^talachtis Hbn. 



The Stalachtis are distributed from Central America to Paraguay and are almost all common animals. 

 They are butterflies of more than medium size varying little in the shape, of a massive, in the 9? clumsy struc- 

 ture. Head long, but not very broad; eyes large, palpi long, especially in the $, the end distinctly bent down. 

 Antennae thick, filiform, at the end a scarcely noticeable thickened club. Thorax and abdomen strong, in the 

 $ clumsy and so heavy that a flight like that of Heterocera or Danaidi is produced thereby. Legs stout and 

 strong. Wings broad with a rounded border, shaped like the wings of Actinote or Ithoniiini. In the veins the 

 uncommonly long cell of the forewing is worth mentioning; the cell seems to some degree still more prolonged 

 by the posterior discocellular reaching the 3 rd radial only far beyond the rising of the upper median vein, 

 which is also the case on the hindwing. The construction of the veins thereby makes a somewhat tugged impres- 

 sion, as if the wing had been stretched into a shape dissimilar to its original one, by secondary influences. This 

 influence might be explainable by the effect of models (Acraeini, Ithomiini) which have influenced all the 

 Stalachtis known without any exception. The larvae are very differently represented; the actual shape is presu- 

 mably that of a compact, cylindrical body with small fine spines across the dorsum and at the sides ; the pupa is 

 fastened to the cremaster similarly to that of Hades noctida, of an oblong shape slightly strangulated behind 

 the thorax, yellowish — or bluish — white with longitudinal rows of black spots {St. calliope). The butterflies 

 are common; they fly in day-time in the sunshine, in a slow flight similar to that of their models, and drink 

 from flowers; in this occupation they are so daring that they may be taken away by the hand if care is used. 

 On being touched, they feign to be dead by folding up their wings above the back, bending the antennae under 

 the body and folding their legs together; in this state they may be cautiously placed on the ground, like a 

 captm'ed Goneptery.v rhanini, without fear of their flying off immediately. Otherwise the animals rest beneath 

 leaves with their wings kept flatly roof-shaped, the abdomen hanging down curved like a sabre. 



phleyia. S. phlcgia Cr. (143 c). Black, body and wings covered with white dots, the base of the wings of a 



pMcgclonia. bright red-brown. Guiana, to the south as far as Para. — phlegetonia Perty (= phlegia Hbn.) (143 c) is the 



southern form flying in Central Brazil, Paraguay, and Bolivia; here there is yet a red-brown, irregular band 



irion. between the basal brown and the border, as it is only sometimes indicated beneath in typical phlegia. — irion
