674 XINTAS; MESENOPSIS. By Dr. A. Seitz. 



/cs.sc. E. Jesse Btlr. (142 g). Here the subapical band of the forewing is broken up into 5 diffuse spots 



and the disc of the wings of a shining violet-blue tinge, traversed by the thick black veins. Beneath the 

 colouring of the wings between the veins is lighter than above, whitish-blue: northern parts of South Ame- 



(icnianis. rica ; Brazil. ■ — aeniacus Hew. (128 c) shows the upper surface of the wings particularly below the costa and 



from the direction of the border dusted with a sooty grey from Bolivia, but there are alsmost typical jesse 



before me also from Bolivia. .f • 



l\ncnri.<<. E. linearis G. and .S'. has almost exactly the size and forewings of the following sericina (128 b), 



])ut the hindwing is without the black margin; from Colombia. 



scriciiui. E. sericina Bar. (128 b) differs entirely from the preceding specie? by the hyaline places being combined 



here to 2 fenestrae: an oblique band before the apex, a longitudinal stripe from the base of the forewing, 

 and a discal wedge in the hindwing. Tliereby a general appearance is produced which is shown by many 

 Heterocera flying in the same district; I mention Mimogyrta panipa (Vol. VI., t. 12 k), Carostatia sajjphira, 

 flaviventris (Vol. VI., t. 22 c), Euagm splendida (Vol. VI., t. 23 h), Agyrta chena (Vol. VI., t. 23 k), Ag. 

 dux, micilia, auxo (Vol. VI., t. 24 a), to a cercain degree even the large Agyrtidia uranophila (Vol. VI., t. 17 a). 

 In this species (like in the model Euagra (splendida) not only the palpi, but also the vertex and hindhead 

 are red-yellow. 



lilhfmiia. E. lithosina Bat. (12Sb). Forewing more stretched, hindwing smaller and in the anal part pointed; 



colouring similar to that of the preceding species, but the hyaline brightening occupies almost the whole 



disc of the wing. Hindhead reddish-jellow. Sometimes there is some red-yellow beneath in the anal angle 



/rmlki. of the forewing; Amazon, Pebas. It imitates small Arctiids, Lmtron, Tithraitstes . — fenella Sm. has clearer 



vitreous spots and, above all, a broader subapical band of the forewing, otherwise similar; from Ecuador. 



ceJina. E. cclina Bat. (142 h). Smaller than the preceding, the hyaline fenestrae not tinged in blue, but 



only faintly darkened by smoky-grey at the margins, the small subapical band white, shaped like in lithosina. 



From the Upper Amazon. This species has no orange-yellow in the forewing and a dark hindhead. ■ — E. 



ai'olia. aeolia Bat. from Guiana and North Brazil has the small band cut trough before the apex by black veins, 



and the black veins in the hyaline disc of the wing are considerably thicker. ,-. v 



imiriii. In addition we mention here (according to Stichbl) the entirely red, black-margined E. inaria Ww., 



described as Lynmas, and which Stichel had formerly himself placed to Xenandra. From the Amazon. — ■ 



isahcUac. isabellae E. Sh. (128 d) is a form from the Araguaya River with almost quite uniform black margins of 

 the wings. It differs from inaria by the latter having another black ray on the submedian of the fore- 

 wing. Apparently very rare. 



hiiirif/ln. E. inariella Strd. from Costa Rica resembles Euselasia chrysippe (121 f), but above it has 3 small 



light spots before the apex and beneath a black border of the hindwing. 



49. Genus : Xiiiias Hew. 



This genus is closely allied to the hyaline Esthemopsis, but the two last subcostal veins bifurcate 

 sooner before the apex of the hindwing. For the rest the species entirely resemble Estk. lithosina. 

 cyiiosema. X, cynosema Hew. (142 h). Wings of a faint violet lustre, hyaline; in the black apical part of the 



hyntndtn. forewing a white, oval oblique band, in the blackish inner margin an orange stripe. Bolivia. — In hyalodis 

 tSiich. (142 f) from Ecuador the small prea])ical band of the forewing is ^^'idened to a large white oval. It 

 imates small lihomiinae. 

 criMdta. X. cristella Sm. from Ecuador is like cynosema. but the orange embedding in the black inner-mar- 



ginal stripe is reduced, similarly as in hyalodis; but the oblique band of the forewing is not widened. The 

 head is yellow (by which it differs from Esthemopsis iithosina). 



50. Genus: Meseiiopsis G. and S. 



This genus belongs yet entirely to the mimetic genera of the Lymnas-gvow^. In the shape it ap- 

 proximates the Xinias and Esthemopsis to which it is undeniably closely allied, but owing to the selection 

 of other models its outer appearance greatly deviates from the former. On the upper surface the black 

 and yellow colouring of the Jo.sia-species from the large group of the Arctiidae is predominant. The fore- 

 wings are long, the hindwings small with a pointed anal part. The cell of the forewing is nearly twice as 

 long as that of the hindwing. The butterflies are mostly rare, i. e. difficult to discover, from the great number 

 of the Josia flying with them; according to Fassl, there is a remarkable difference between the model 

 and copy in the imitating Erycinidae being more timid and flying off sooner than the Josia. serving as their 



model. ,'■ Vu ,."•-!» '" 



l:rya.ris. M. bryaxis Hew. (128a). Wings with an orange-yellow disc and broad black margins. Central Ame- 



innhtiwrhin- rica. In the J the orange colour is deeper, in the $ lighter. Rare, ■ — melanochlora G. and <S'. (128 a). Here 



''"• the ora]ige is more in the shape of stripes, running from the base of the wings to the middle of the border. 



(!entral America to Bolivia. Rare; the model in Colombia is Josia fulva (Fas.sl), in Costa Rica Jo.iia ligata.
