494 CAT A GRAMMA. By J. Robee. 



wings. Beneath it resembles mionina (101 B c), from whicli it differs, however, not only by the shape and posi- 

 tion of tlie yellow band of the forewings, but also by the distal light band not being yellow but glos.sy blue. 

 mcna. C. mena Stgr. from the Chanchamayo (Peru) is but little larger than mionina, but has a larger broad 



ochre-yellow band of the forewings which is placed more in the length of the wings and which starts close 

 at the costal margin and terminates shortly before the distal margin near the angle; the blue .spot on the 

 hindwings is much larger. On the under surface of the hindwings the 5 blue spots are larger and prolonged. 



discoidalis. C. dlscoidalis Guen. The translated description runs thus: Small. Oval, broad orange-coloured spot. 



Oblong blue spot of the hindwings beginning from the base. Under surface with only 4 not pupillcd dots before 

 the central band and 3 at the anal angle. Broad yellow lines, the first posteriorly united with the 2nd and 

 3rd; the latter rises again close on the yonder side of the first dot. Colombia. 



parificn. C. pacifica Bates (= bugaba >Stgr.) (101 B d) from Central America is the smallest specie.s of this 



genus. The .steel-blue reflection of the hindwings is of varying extension, and beneath the black markings vary 

 a great deal. 



aajiiia. C, aegina Fldr. (101 Be) from Ecuador, Colombia and Bolivia has broader yellow bands, but jjlaced 



in the same way as in lyca. The $ has a more compact shape and the blue spot on the hindwings is smaller 

 sahnnis. and divided by the black veins. — salamis Fl<h\ is the form from Rio Negro and from Peru with a broader 

 yellow band and diminished blue spot of the hindwings. 



(hiliina. C. dulima Guen. This species has been described in the following way: very nearly allied to zelphanta 



from which it differs only by the following : Subapical .spot with white and violet margins on glossy ground. 

 Hindwings beneath decidedly light lilac with very light siskin-yellow base and central part, the latter strongly 

 mixed with lilac. Central .spots smaller, more distant from each other and with finer black margins. The black 

 subterminal line is undulate, or rather consisting of crescents and encircles metallic sky-blue scales. Peru. — 

 The author lays stress upon the possibility of the coincidence of dulima with zelphanta or hystaspes. 



zclphaiila. With C. zelphanta Hew. (101 B d) from the Upper Amazon we commence the series of redbanded species. 



In this species is, beside the greatest part of the hindwings, also the basal part of the forewings of a faint 

 blue gloss. 



Iiydii.-ipcs. C. hydaspes Drury (= lyrophila Hbn., hcsperia Perty) (101 Bd) from Southern Brazil and Para- 



guay is a neat and frequent species. Red band of the forewings narrow, glos,sy .spot of the hindwings large. 

 The $ does not differ from the ^. 



hn-acJilus. C. hcracUtus F. from Brazil is denoted by A. G. Butler as nearly allied to hydaspes (= hyrophile), 



without mentioning any difference. 



hij-flaptcs. C. hystaptes F., coming as stated from Brazil and Bolivia, has been described as follows. ,, Wings 



blackish-brown, witii blue gloss, hindwings beneath yellow, with black ring-lines and 3 blue dots." Presumably 

 the animal is an aberration of hydaspes, or the author may have had a normal hydaspes before him and 

 may have forgotten to mention the red band of the forewings in the description. 



koliiiiia. C. kolyma Hew. (101 B d, e) and pasithea Hew. (101 B e) from the Upper Amazon look very diffe- 



pasithm. rej^tiy above, but are still forms of only one species, since all the transitions are noticed. 



felderi. C. felderi Hew. from the Upper Amazon differs from cajetani Guen. (= audofleda Thieme) (101 B e) 



cajeiani. fj.Qj^j Peru by the yellow band of the foreM'ings and a greater extension of the blue gloss in the hindwing. 



codoinaii- C. codomannus is divided into a greater number of local — or temporal forms, codomannus F. 



""■'*• (= sinamara Hew.) (101 B e, f) from Brazil lies before us from Eastern Colombia (Medina, 500 m), from the 



(isfatre. Collection Fassl. This form hardly differs above from astarte Cr. (101 B f ) from Bolivia, but the red bands 



of the under surface of the forewings are broader in astarte. The $ has a brick-red basal half of the fore- 



antillena. wings. — The form atltillena Kaye (101 Be) from Trinidad is .somewhat smaller, has narrower red bands of 



mUilaris. the forewings and a broader red band of the hindwings. — militaris Stgr. from Venezuela has a violet 



reflection of the upper surface, the ai^ical spot is absent and the red ))and of the hindwings is reduced to a little 



miles, stripe at the costal margin. — miles Bates from the Upper Amazon has very much enlarged red bands of 



sditna. the upper surface which are sometimes confluent on the forewings. — selitna G%ien. (= cynosura Hew. pt.) 



from Minas-Geraes is a smaller form showing only narrow red bands of the upper surface and preijonderantly 



stratiotes. yellow colouring of the under-surface of the hindwings. — stratiotes Fldr. is the form from Ecuador. 



exceU'wr. C. excelsior Hew. (101 B f) from the Upper Amazon has a magnificent deep-blue reflection and a 



yellow transverse band of the forewings. The $ has only the shining blue .spot at the inner angle of the hind- 



excehUs'i- wings, but no reflection. — excelsissima Stgr. (101 B f ) from the Upper Amazon (Sao Paulo de 01iven9a) has 



michacU ^ S^^'^'^y "^^^'^ upper surface with a red band of the forewings which is reduced in michaeli Stgr. from Manicore 



pasiazza. oji the Rio Madeira to a short basal .stripe. — pastazza Stgr. (101 B f) from Ecuador and Peru (Chanchamayo)
