664 SYRMATIA; ZEOXIA. By Dr. A. Seitz. 



alcyoneus. attain an enormous size, though perhaps not in every year; I denominate these large specimens alcyoneus ab. 



polyplaga. nov. (132 b). These have again another modified form polyplaga form. nov. (132 b) in which the spots of the 

 forewing are enlarged, the orange of the hindwing. however, divided into 2 or 3 spots. This form is before 

 me from the Coll. Baxg-H.-vas without the patria being stated; the forewing also exhibits above the anal 

 angle a third orange spot which is unfortunately somewhat indistinct in the figure. 

 mona. B, iTiona Wic. (132 b). Like meJanops, but also the hindwing has an orange band at the distal mar- 



gin, extending from the little tail to the anal angle. In this species the orange likewise varies in extent at 

 every habitat. In typical specimens it does not only run from the costa of the forewing to the distal mar- 

 gin, but it follows it lip as far as to the anal angle. The specimen I figure deviates already by the orange 

 band not running continuously as far as to the anal angle, but a disjoined spot standing isolated at the 

 anal angle. — If this spot is also absent and another reduction of the bands takes place, we have ab. 

 moneia. moneta Sfich. before us. A specimen from Huancabamba lacks all the orange on the forewing. I must 

 remark here again that all the specimens I captiured at one place, were always exactly corresponding, but 

 that alreadj' at the next finding-place small deviations were noticeable. ■ — South Brazil, not rare, but very 

 local and apparently never leaving their flying-place. 



7iHirghwia. B. marginata sp. nov. (132 b), brownish black Avith an orange-red collar. The apical margin of the 



forewing and the whole distal margin of the hindwing, including the xiphoid, honey-yellow. Bahia. The ani- 

 mal is decidedly influenced in its colours by a form of the Lymnas aZerea-group or its model, alena itself was taken 

 onlj' somewhat to the south of it, near Rio de Janeiro, but it is only necessary to look at the animals in 

 order to conclude that both must occur together, and were not j^et taken at the same place only owing to 

 their great rareness. 



33. Genus: ^yrmatia Hhn. 



In this genus the hindwing is still more monstrous than in Barbicornis ; the costal margin of it is greatly 

 shortened, whereas the anal part of the hindwing accompanies the tail-appendage for a longer distance. All 

 the forms probablj^ belong only to one species exhibiting a special character at most of the habitats; but it 

 may be out of the cjuestion that more than one form occurs at the same finding-place. The butterflies are wide- 

 spread, flying in day-time in the sunshine at open spaces in the woods, with so great a resemblance with 

 certain H ijt)ienoptera and Diptera that I always captured them only when I was on the special look-out for 

 such insects; but never when I was exclusively hunting for butterflies. They seem to be local, but by no 

 means rare. They mostly choose their resting-place on the tips of the highest branches of high bushes or 

 small trees. I have never found them on flowers. 

 dorilas. S. dofilas Or. (= asteris Gray) (132 b). Forewing with a red small basal stripe and an oval white 



discal spot which differs somewhat at every habitat. Stichel presumes that the 2 has a white basal streak 

 at the forewing, which, however, does not match my Santos- $$. ^ and 2 probably resemble each other, 

 though differing according to the locality, as is the case in nearly all the American Erycinidae. — The form 

 nyx. without the small red basal band was denoted as nyx Hhn. ■ — In lamia Bates the small basal band is white 

 lamia, g^^^j continued across the hindwing: in astraea Stgr. (132b) it is red on the forewing, light-yellow on the 

 aethiops. hindwing; — aethiops Stgr. (132 b) is entirely black, also the white discal spot of the forewing being absent. 

 ■ — • A very peculiar form lies before me from the Coll. Fassl from Villavicencio (Colombia). The ^ exhibits 

 the basal spot of the forewing entirely black A^ithout the little band; in the disk there is a white oval, about 

 as in typical dorilas. The hindwing is entirely black; in the $, however, it exhibits such a broad, ehtireh- 

 white band that the whole anterior half of the wing appears white except the extreme base being narrow- 

 black. — The range is stated to be South America from the northern coast as far as South Brazil; but 

 with W. ScHAtrs I saw a specimen from Costa Rica (forma aethiops). 



34. Genus: Zeonia Swns. 



By the long-stretched shape of the hindwing being even prolonged by the tail-appendage it resembles 

 the preceding of which it reminds us also bj' the restless, almost w^hizzing flap of its wings. The resemblance 

 with insects of other classes (especially Hymenoptera) already mentioned in Syrmatia is even increased in 

 zeonia by the hyaline wings. Bodj- somewhat more stretched than in Syrmatia. otherwise the structure al- 

 ready ajiproximates the next genus, but with considerably shorter palpi being hardly visible above and pro- 

 jecting in the Diorina sometimes in the shape of a nose. The butterflies occur singly and very localty, but 

 most of them are not very rare. 

 nmn:nn. Z. amazon Sndrs. (130 g). This amazon-species of w-hich we figure a very large $ is in itself one of 



the largest of the genus. It is characterized h\ the whole anal half of the hindwings being black, the anal 

 lobe itself, however, broad vermilion; the tails are relativelv short.
