624 EUSELASiA. By Dr. A. Sfim. 



part of the margin orange. The $ has instead of the blue spot a white discal.spot. Probably very widely distri- 

 buted like the preceding species, though very rare; from Guiana along the Amazon to Pebas. 

 eucritus. E. eucntus. By this a number of butterflies are presumably combined varymg m every habitat. 



Colombian ,^,^ have above a beautiful violet lustre covering the basal half of the forewings and the distal half 

 of the hmdwings. On the under surface, the proximal stripe at the anal fold of the hindwing bends round once 

 more and runs towards the costal margin near the base, so that the hindwing receives one more transverse 

 stripe. The describer himself already figured as ^J and $ specimens from different habitats which do not belong 

 together. Specimens from the Rio Negro in East Colombia exhibit next the base of the wings, instead of the 

 inner stripe being bent back, a large round jet-black spot and above a magnificent blue reflection; we 



catapoecila. denominate this form catapoecila form, nov., because it has quite a strange appearance thereby, being also 

 larger than all the other forms. Beside the specimens from Colombia there are also such from Santarem (Ama- 

 zon) before us. The other forms can remain nameless. 

 gelon. E. gelon Stoll ((J = sabinus Stoll, tenage Hbn.) (121 b). cj of a deep blackish brown with a vermilion 



wedge-shaped streak at the inner margin of the hindwing. $ lighter with a yellowish-red anal part of the hind- 

 wing. Under surface greyish-brown {^) or yellow ($) with three yellow marginal stripes. Very variable; the 

 red stripe in the ^ may be broader or narrower, it may reach the base or the distal margin or not, it is mostly 

 smaller than in our figured specimen (from Surinam). In i$^ from Cayenne the red apex of the hindwing is 

 bordered in black. In the $ the red spot on the upper surface of the hindwing varies greatly and may in some 

 places be covered with black. On the under sm-face the yolk-coloured spot before the middle of the distal 

 margin of the hindwing may be bordered by black or not, the habitats of the different forms may be situated 

 quite close to each other. Guiana, not common. 

 zena. E. zena Hew. (121 a). ^ above with a large red spot of the forewing and a very small spot of the 



hindwing. Beneath blackish-grey, before the distal margin 2 white stripes. $ above lighter brown, the red 

 spot of the forewing transverse-oval, the spot of the hindwing larger and reaching the distal margin. On the 

 Amazon River, near Iquitos, less rare than the preceding species, though very local. 

 erythraea. E. erythraea Hew. ($ = coccinella Bat.) (121 a). ^ distinguishable from the (J of zena by the larger 



hemochrome-spot ozi the upper surface of the hindwing, and particularly by the under sm-face exhibitiiig 3 light 

 (instead of 2 white) stripes before the margin. Moreover very variable, at the single habitats exactly equal. 

 Forewing sometimes with a broad, sometimes with a narrow, black border; the spot of the hindwing some- 

 times proximally indented, sometimes also, in the (J, reaching the border. $ similar to that of zena, forewing 

 more intensely red, nearly as much as in the cj. Colombia and Amazon, Iquitos, Tunantins. Rather rare. 

 eutaea. E. eutaea Hew. (121 b). The ^ lying before me from the Paris Museum from Nouveau-Chantier 



(French Guiana) resembles entirely the figured $, but the red is more fiery and extends in the forewang as far 

 as to the inner margin, in the hmdwing almost to the base. Under siu-face of both sexes nearly exactly like 

 in a small gelon, though the costa of the forewing is black. Certainly, like most of the allies, very widely 

 lindana. distributed (Guiana and Amazon), but verj^ rare. — lindana MscJil. is surely only a $ of eutaea from another 

 habitat (Surinam), in which the black costal stripe on the under surface of the forewing is absent, so that 

 the under surface resembles altogether that of the $ of gelon and erythraea. 

 euriteus. E. euritcus Cr. (= euritaeus Hew.) (121 b). Under sm'face alike in (J and $, whitish with a loam- 



yellow base of the wings and 3 brown parallel stripes. Above the (J is black, the forewing with a blue arcuate 

 spot from the base to the anal angle, the hindwing with a blue distal spot. $ brown with a yellow distal spot 

 in the anal part, being differently shaped at each finding-place, as well as the stripes of the under surface 

 gration. in the (J and $. — As gration form. nov. (121 c) we denominate a form from the Amazon with a broad 

 blue oblique band of the forewing and an orange-yellow ground-colour of the under surface; in the $ the orange- 

 cMrilis. yellow spot of the hindwing is above considerably narrower. — - In charilis Bates, likewise from the Amazon, 

 the latter is absent altogether, and in the ^ the blue of the upper surface is spread more across the surface 



calligmm- of the wings. — ■ calligramma Bates. Here the (J has white-speckled fringes of the hindwing, the $ is above 

 '"*■ light-brown; both sexes are beneath more strongly and densely striped; one stripe runs along the costa of the 

 forewing and the imier margin of the hindwing. From Ega ; known to me only from Botes' description. Not rare. 

 eutychus. E. eutychus Hew. (= orfita Cr. pt.) (121 c). ^ above black with a faint violet lustre of the centre of 



the forewing and a marginal band of the hindwing with a bright violet reflection; $ earthy brown with dia- 

 phanous stripes of the under surface and a stout dot before the middle of the border of the hindwing. Beneath 

 3 or 4 parallel stripes across both wings and before the middle of the border of the hindwing a large black 

 eye-spot with a blue reflection. Rather common and very variable, especially as regards the intensity and 

 position of the blue reflection, and the thickness of the stripes on the under surface. More than 100 specimens 

 fcrrugo. are lying before me, 50 are in the Tring Museum. — ferrugo Bat. from Teffe (where, however, also typical 

 eutychus fly) exhibits the two outer transverse stripes of the under surface flown together to a very thick band; 



dyrrh'ichius. — • in dyrrhachlus form. nov. (121 c, d) they are more divergent towards the inner margin of the hindwing. At 

 the same time, this form exhibits a very bright hyacinth-blue reflection in the inner-marginal region on the 

 under surface of the hindwmg, which is hkewise well developed in eutychus from Teffe, being paler and more 

 clithra. purple-violet in Colombians and missing altogether in Bolivians. — clithra Bates (121 d) shows the brown 

 stripes of the hindwings narrowed cuneiformly towards the inner margin, the space between there white with 

 a magnificent hyacinth-blue reflection. Tj^pical specimens are found on the Lower Amazon (Santarem, Para); 

 specimens from the Upper Amazon approximate dyrrhachius from Guiana, and intermediate forms originate 

 from Rio Jurna. Not rare.
