— stilbos Stich. (134d) is the representative of the species from Coloiiihia, in wliich tlie proximal metallic sfiiims. 

 line is broader also on the forewiiifr and, on the hindwiiiEr. so bioad that it is jiartly confluent with the distal 

 one. — On compositae common. 



Ch. panurga Stkh. has an under surface similar to that of nnius. hut it is considerably larger and pimuriia. 

 has only 1 silvery line and white fringes; the upper surface is blackish-grey with a. blue lustre, similar to 

 hermodoid. I do not find the ]iati'ia being stated. 



Ch. lypera Bat., from the Ujtper Amazon, has already the size of the following form and also its hnid-ii. 

 dark brf)wn upper surface: the black discal spots are partly confluent to a median line, the reddish distal 

 marginal band is defined by a silvery line, traversed by a row of riots. Ujiper Amazon; very closely allied 

 to chaonitis (134 d). 



Ch. chaonitis Hew. ( 134 d). Very similar to the preceding species, but instead of the black line formed <h,i„iiiii.^. 

 of fine streaks, a sinuous nebulous band runs through the centre of the wings. From Guiana to Bolivia. 



Ch. chelonis Heir, stands in the middle between chaonUis and efijessa. The distal silvery line is ab- <'licl<,)iU. 

 sent altogether or it is exhibited only in single, small silvery scales, the proximal line being also duller. 

 Also the colouring forms the intermediary between that of rhaovili.s and epijesm. being in specimens from 

 the lowlands (Rio de Janeiro) yet I'ather violcttish-brown. in those fiom the highlands moie dark brown. 

 Apparently very rare; specimens like those figured by Hewitson are not known to me at all. but oidy such 

 forming transitions to 



Ch. epijessa Pvittw. (= calicene Hen-., calinice Stich.) (134 b, as chelonia) from the summit of the r))iir.^<<((. 

 ('orcovado and from the Organ Mountains; here, however, the ground-colour tuins entirely fox-coloured, 

 the silvery lines are entirely extinct beneath, while above they are so only here and there, the black dots 

 in the marginal band are finer, but owing to the lighter ground-colour more jDrominent than in typical che- 

 lonis. Moreover both forms, exhibiting probably differences of the habitats ( ? elevation), are very closely 

 allied to each other, Init the ^ of chelonis has broader forewings. — As a smaller, darker form from the south 

 (Espiritu Santo) charis Hen\ may be considered, in which the proximal silvery line is sometimes fairly well rhari.^. 

 preserved, but sometimes also hardly recognizable. This is probably also the place where azora Godt. belongs, iizara. 

 which is unknown to me, although I collected numerous Charis to be inscited here in its patria South Bi'Hizil ; 

 it may be oidy a subracc of Charis charis. 



Ch. velutina G. and S. (134 c) has the shape of chelonis. but a darker, almost black colouring which, rrluiiiui. 

 in the (^. shows beneath a bluish tinge. Recognizable by the proximal metallic line being irregular, several 

 times interrupted. Central America to Colombia. — iris litgr. belongs hereto, according to the description, iri.'<. 

 though nothing is mentioned regarding the course of the proxmial silvery line; it is denoted to be ,,the 

 most closely allied to cleonns or znnui'\ iris is unknown to me; from the Chiriqui. 



Ch. cadytis Heu\ (134 c, as cadytes). Easily recognizable by the ])roximal silvery line being shaded (ndi/tl^:. 

 orange-yellow above at the costa. South Brazil, Paraguay. — acroxailtha Stich. (134d), likewise from South iiini.nnil/ia. 

 Brazil, is said to have ,, transformed the red submarginal stripe of the forewing to an ochreous-yellow, oblong 

 subapical spot"; but as the author declares not to be able himself to tell whether our figui'e represents one 

 or the other form, the name is probably better to be abolished. 



The I'ollovvins species, mostly t'l'diu .\'<irtli Aiiit'rica, deviate from ( liose enumerated so far in several details (tiemis 

 Calephcli.t dr. and l{(ih.): tliey have somewliat more ntituse forewings. but iii-arly always distinefly the silvei'v lines of (lie 

 f'hari.i-!^peciefi.

 3 or 4 arcuate rows. United States, more to the east and rare. 



Ch. nemesis Edtr. is presumably only the western representative of the preceding, from more arid "i^f^.s;.*. 

 di.stricts of Arizona and South California, considerably smaller (only as large as caenen.^): across the middle 

 of the wings above runs a dark, angular shade, more distinct than in borealis. 



Ch. australis Edw. (= guadeloupc Sireck.) (134 b) is likewise very closely allied to the jJicceding. but mi.-^ini/i.-.: 

 it has darker markings than nemesis; the brown median band is more prominent, the wings are without the 

 white dots of the fringes exhibited in nemesis. Mexico, Texas. — costnricola Stgr. exactly corresponds with 

 australis. as it flies in some places of Mexico (Misantla). — fulmen Stich.. like the jireceding from Costa Rica, iiiliiiin. 

 is uid^nown to me; it is said to have the form of iris, but a black l)ati(l acioss the middle of the wings 

 and speckled fringes. Under surface light rusty brown. 



Ch. caeneus L. (= pumila Bsd., virginiensis Gray) (134 c). The name is assigned to a somewhat du- (■(icnru.t. 

 bious species of Linne, as which, however, the Ijutterfly belonging here was generally considered, although 

 the name was several times misspelled as caeiiins, cenea. cerieus, cerea etc. Fresh sj)ecitnens exhibit the brown, 

 black-spotted upper surface finely sticwn with isolated blue, somewhat metallic, small silvery .scales being
