630 EUSELASIA. By Dr. A. Seitz. 



a smaller spot in the middle of the hindwing, and a third one before the anal angle of the hindwing. Central 

 America and Colombia. 

 haJuieli. E. hahncH Stgr. (= hahneli Mengel) (122 f) from the Upper Amazon, to the south as far as Bolivia 



(Coll. Fassl) and South Brazil, has beneath almost exactly the same marldngs as argentea, but bone-yellow 

 instead of silvery; above the base of the forewing and the whole hindwing of a bright red, except the costal 

 margin and the upper distal margin. The $ is above more yellowish-red and at the hindmng only the costal 

 margin is blackish-brown. Near Rio de Janeiro rare; maybe more common in the north. 

 jorduenna. E. corduenna Hew. (122 f, g). Above black, the basal part of the forewings and the anal part of the 



hindwings of a magnificent blue reflection. Beneath silvery yellowish-grey with a dark border and 3 transverse 

 stripes the proximal one of which runs differently, according to the finding-places, sometimes in a straight 

 line, sometimes curved, forming a pointed or an obtuse hook on the hindwing. From Central x\merica through 

 Colombia, Ecuador and Peru as far as Bolivia and Central Brazil. Not rare. 



alcmena. E. alcmena Drc. Forewing dark brown, the palest at the apex of the forewings. Under surface light 



tan-coloured, both Agings in the middle traversed by a narrow orange band ; between the latter and the border 

 a faint, brown undulate line; hindwing mth a submarginal row of small black spots the fifth of which is the 

 largest. Smaller than the following species. Ecuador. Unknown to me in natme. 

 uriies. E. Ufites Hew. (122 a). Above blacldsh-brown with a very faint blue gloss, beneath yellowish silvery- 



grey with only one transverse line being slightly curved. There is quite a number of equally coloured Euselasia 

 ' being distinguished only by the com'se of this transverse line. The course of this line of the under sm'face has, 

 already since Hewitson, been considered a characteristic mark of the species, but in coi'duenna, eugeon, thucy- 

 dides etc. being quite distinct species we may notice that this line itself does not even characterize the sub- 

 species. The forms being above brown, beneath silvery may, therefore, belong to few species distinguished 

 by the shape of the wings, the shading of the silvery area etc. 



eusepus. E. cuscpus Heiv. (122 a) is like iirites, but above without a blue gloss; the line of the under surface 



is on the hinch^ing farther away from the border, and before the anal angle, one partr of this line (unfortunately 

 missed in the figirre) is pushed forward towards the border. I have specimens before me from Pozuzo (Peru), 

 in which this projecting part of the line is yet connected with the other links of the line, thus forming an inden- 

 tation being convex towards the border. This may be of a very different extent, the most in South Brazil and 

 Bolivia, the least in Peru where we already notice transitions to urites from the Amazon, sometimes with quite 

 a faint blue reflection; there the line of the under surface mostly runs continuous. etfsejaMS always has a sUvery- 



eumenes. white forehead. — eumenes Heiv. Here the under surface-line is not pushed forward before the anal-fold, but 

 in typical specimens still somewhat interrupted before the anal fold. On the whole, ewnienes has somewhat 

 more pointed wings; from the Amazon. — Om' figure shows a very similar form, somewhat larger, the under 

 surface-line uninterrupted, the under surface itself of a purer silvery colour, without a yelloAvish tinge; nume- 

 rous equal specimens from Monte Tolima, captured by Fassl, and in the Paris Museum. The $ is beneath 

 exactly like the ^, whereas the $ of eusepus is beneath lustreless greyish-brown; I call the form which may 

 eupatra. be a distinct species, eupatra subsp. nov. (122 a as eumenes). — In cataleuca FIdr. from Mexico the postmedian 



ca a euca. ^^^g j^ absent altogether and the under surface exhibits a very light silvery area without any markings. 



maiuta. E. matuta Schs. (142 c) described from Costa Rica, from where it is before me from Orosi, 1200 m. 



Above the black forewings have a yellowish-red, small discal spot, the hind^vings a brownish-red lustre. Under 

 surface silvery \^'hite ^^'ith a straight dark postmediarr line arid some small black dots before the border of the 

 hindwing. 



betiina. E. bettina Hew. (122 a). Above dark brown with a scarcely noticeable light-bluish lustre; beneath 



yellowish grey, of a bronze gloss, before the middle of the border of the hindwing a small dark dot. From Cen- 

 tral America to Ecuador. Locally common. 

 candaria. E. candaria Drc. (142 c). Lilve the preceding species, but beneath golden yellow, lustreless. The 



small dot before the middle of the border of the hindwmg is larger and some more finer ones are before the 

 border of the anal part. Colombia, not rare; often in the ,,Bogota"-consignments. 



pheiina. E. phelina Drc. Larger than eumenes. Upper surface one-colomred light brown, under sinface of 



a pure white. The forewing is, from the costal margin to the inner margin, traversed by 5 narrow, pale brown 

 bands; the distal margin is bro-wm. Hindwing traversed by 3 brown bands not reaching as far as below the 

 cell; close at the distal margm, in the centre, there stands a large black spot and a small one nearer to 

 the anal angle; the space between the two spots is yellow. A submarginal, undulate brown band traverses the 

 wing from the apex to the anal angle. From Maracaibo (Venezuela). 

 cumedia. E. eumedia Heic. (= ophias H.-ScJidff.) (122 d). Above quite blackish-brown, without any gloss 



and reflection. Beneath the transverse line is red, as well as the border of the hindwing, in ^^'hich we notice 

 black, white-edged dots. From Colombia to Peru, not common. Typical specimens from Colombia have a 

 very dentate border of the hindwing; in the much smaller Peru-specimens the latter is rounded, the costa
