EUEIDES. By Dr. A. Seitz. 



spot. It flies in Peru in company of the similarly coloured Hel. melpomene as well as of some Actinote and Pie- 

 felderi. rids which resemble it. — A transition from the last described form to canides is felderi Stick., which closely 

 resembles E. pluto, but still retains the red rays. None of these forms are scarce, but not easy to recognize among 

 the numerous Heliconius flying about; indeed it is only after one has learned to distinguish the Eneides 

 from Heliconius by the slo^ver motion of the wings, that one may hope to capture larger numbers of them. 



deolaea. E. cleobaea //6«.-(?. received its name from its close resemblance to certain species of L^/corea, although 



Lycorea cleobaea itself possibly was not its model. Forewing brown-yellow, intersected by black longitudinal 



zoreaon. stripes. The type is found in Cuba and Porto-Rico. — zorcaon Beak., ranging through Central America as 



far north as Mexico, differs but little, in having the black ajiical markings of the forewing increased, in 



consequence of which the bands, which are somewhat lighter and in the $ rather pale yellow, are broken 



adusta. up into several more or less separate spots. — adusta Stick. (SO g) is an inconstant intermediate form, from 



Chiriqui and Honduras; hindwings with the band dissolved into a series of spots. Not scarce. 



E. isabella resembles somewhat the preceding species, but the longitudinal striation of the wings is 



less regular. The forewings have the apical half more profusely marked with black, often black throughout ; 



on the hindwings the median band is as a rule broken up. All the forms shade quite imperceptibly into one 



another so that the names given them have but little vaJue. We figure here all the distinct forms, taken 



for the most part from the original types. As a rule the difference in coloxir is only due to the fact that in 



isalella. the several localities they ha.ve followed different models. The name-type isabella Cr. (80 d) occurs in the 



eastern portion of South America from Guayana to Central Brazil, according to reports as far as Bahia (where 



I found, however, only E. dianassa). Before the black apex an isabel-coloured oblique band similar to that 



we find in much worn or faded specimens of dianassa; but it differs from dianassa in having the large 



white or sulphur-yellow subapical spot replaced by a row of 3 — 4 small, pale coloured, isolated spots. In 



dtssohda. typical isabella the hindwings have the median band uninterrupted, whereas in dissoluta Stick. (80 f), from Peru 



arquata. and Bolivia, this is dissolved into isolated spots. — An intermediate form is arquata Stick. (80 g), having the 



median band also divided into spots which, however, are still touching one another; on the forewings the yel- 



imitans. low subapical spots larger. Colombia and Panama. — imitans form. nov. (80 f ) approaches dissoluta, but the 



huhneri. sulphur-yellow oblique band is absent, being replaced by the ground-colour. — In htibneri Men. (80 f ) the obli- 



dynasies. que band is dissected into 3 spots separated by black; from Colombia. — dynastes Fldr. from Venezuela 



pelludda. has the band loosely connected, in the $ yellow-ochreous, similar to that of pellucida Sriika (80f) from western 



South America, distinguished from the others by having the median band reduced to a row of small oval spots. 



seitzi. • — Very similar is seitzi <S7;c/i. (80 f), from Colombia and Ecuador. Upper surface only marked with tAvo colours, 



vegeUssima. the oblique band as well as the apical spots being replaced by the ground-colour, whereas in vegetissima 



Stick, the sulphur-yellow band and apical spots stand out clearly upon the deeper ground-colour. From Ecua- 



hippolinus. dor. — hippolinus Btlr. (80 e) from Peru resembles seitzi, but has the a.pex of the forewing entirely black, 



mar(7a)*/eTO. without any spots. — The same is the case in margaritifera (S^ic/;. (80 e), which has, however, the median band 



personata. of the hindwing broken up into oval black spots. — personata Stick. (80 e) resembles the latter, but has on the 



forewing the black colouring so much increased that it not only covers the entire ajiical area, but spreads to the 



Irunnea. middle of the wing where it confluesces with the black spot at the apex of the cell. Peru. — brunnea Stick. 



(80 e) is again like personata, but has on the forewing the black apical area interrupted by a chain of spots mar- 



spoliata. ked like the ground-colour. Likewise from Peru. — ab. spoliata Stick, from the Cauca Valley is based upon a $ 



in which the black markings are so much increased that on tlie forewing the ground-colour is almost completely 



obscured, and on the hindwing interrupted by an unbroken, heavy median band, isabella is, whereever it occurs, 



very common. 



dianassa. E. dianassa Hbn. (80 d). Very much like the preceding; the forewing with a generally sulphur- 



yellow oblique band which in worn specimens fades to dull ochreous. At the apex a snowy-white, obliquely 

 oval spot, occasionally tinged with yellow or dusted with black and followed (before the very apex) bj' a few 

 white dots faintly shining through from underneath. Typical dianassa exactly copy Hel. narcaea (72 a) with which 

 they associate. At Santos where the latter has the costal streak of the hindwings dusted with red, that band 

 decolorala. is also in dianassa generally tinged with ochreous, and decolorata Stick. (SO d) which accompanies the similarly 

 coloured narcaea f . satis, lacks on the hindwing the pale yellow band altogether. In the company of dianassa 

 we find, besides H. narcaea, a great number of similarly marked butterflies, such as Protogonius drurii, Melinaea 

 etkra (33 d), Meckanitis lysimnia (34 b) and nessaea (34 b), Ceratinia euryanassa (35 b) etc., all of which occur in
