P„hl. -w. III. 1917. DTORINA. By Dr. A. Seitz. fifir, 



Z. timandra Sndrs. (130 g) is somewhat snip^ller; the hindwiiigs, however, are narrower, espeeially liDiamlrii. 

 in the anal part, the anal lobe itself is broad black, but above it is a small vermilion i>anfl under which 

 there are mostly small white dots. Central and South Brazil; Rio de Janeiro, larc. 



Z. licursis F. (= Xanthippe Grmj, morissei Blrh.) (130g as lycursis) likewise from .South Brazil (Rio lir,n:<iis. 

 Grande do Sul). Recognizable by the red in the small anal band being broken up into two small separate apjjo- 

 site spots of a variable size. 



Z. sylphina Bat. (13()g). An imposing form with broad bands, the small anal band being detached ^uliihhui. 

 from the inner margin of the hindwing. the latter itself, however, as far as the base of the wing hemochiome 

 (= typical sylphina) or yellowish-red (ab terpsichore Stick.). Ecuador, Peru, Bolivia. — In a ,,subsp.". gratiosa l<riisiri,i„r. 

 Stirh.. likewise occurring in Ecuador, but unknown to me, the I'ed anal spots are said to be ,,very large" and !/''"'"'■'"'• 

 of a ,, violet lustre". 



Z. helicoilides Swufi. (= heliconoides Sndrs.) has exactly the size, shape and black bands of sylph itui: hdicoiiiiJpR. 

 but the red of the small band of the hindwing wliicli is broad and ananlarl\ broken does not continue cowards 

 the base. Swainson, according tho whose figure I describe the species, states ,, Brazil" as its patria, but no 

 special locality. 



Z. faunus F. (octavius F.. chorineus Cr.) (13()g). This finely banded species is easily recognized by fainiun. 

 the red anal hjbe whicli is only outside delicately bordered in blacl-' being ch'awn out into a red apex. This does 

 not occur in any other species. Guiana, Amazon Venezuela and the Isle of Trinidad. — bogota Sndrs. is some- hai/nin. 

 what more strongly banded and margined in black, and the hindwing broader black. Colombia and Central 

 America. — Also in the faiorxs-formx the red may turn into dark yellow, as probably in all the Zeoniar, such 

 specimens are orchestris Stirh. on-hrsiri^. 



Z. batesii Sndrs. (130g). This little species is immediatelv recognizable by the hyaline area of the /)»/<■.<;;. 

 hindwing not being once nun-e divided by a black band, as in all the other Zeonia. From the middle Amazon 

 (Itaituba, Obidos, Rjo Tapajoz). lare. 



3'). Genus : Dioriiia Mor. 



Very much like the preceding genus, recognizable by the greatly ])rojecting paini; in some 2? they 

 are longer than the head. The shape of the wings resemliles very much the ijreceding genus, particularly the 

 long anal margin of the hinthvings resembles Zeonia, as well as the swoid-like tail-appendage. But the surface of 

 the wings is no more hyaline, but black with a bright blue reflection in the qq and some $9- t)nly 2 or 3 

 species are known, but they vary greatly. The imagines visit wet stones and places in the road in the mor- 

 ning, sometimes they are also seen playing round the tops of bushes in the sunshine. Their range extends 

 from Mexico to South Brazil a)id Bolivia, often being rather common at their hibitats. 



D. arcius L. (= butes L., licarsis F.. rhetus Cr., ciamei'i Sicns.) {I30f. misprinted into ancins). This arrin-'i. 

 butterfly occurs in three forms in its range extending from Mexico to South Brazil and Bolivia: a northern one, 

 thia Mor. (130f), being distributed all over Mexico and Central America, with very fine hyolijie bands and //">/. 

 a bright blue gloss of the upper surface. In especially dry and hot localities the bands are narrowed so 

 much that they almost disappear; they have changed into fine lines which make the animal appear f[uite dif- 

 ferent. This form seems to me to agree with castigatus Stich. (130 f); it is apjjarently confined to small districts castif/atus. 

 of Mexico and Panama; the figured specimen originates from the mountains to the north of Agapulco. — 

 The second form is the southern one, being distributed from Bolivia, Peiu and Brazil to the north as far 

 as the Amazon: it is huanus Sndrs. (130 f), recognizable by its smaller size, a duller blue reflection being huami.'i. 

 confined almost entirely to the parts of the tail, and by a somewhat undulate distal hyaline band, the proxi- 

 mal one being broader. — The third form is the typical arcins inhabiting the rest of the range, particularly 

 Guiana and the adjoining parts of North Brazil; it is still smaller, with broad bands, the j' \\ith very thin 

 and long, strongly bent tail^. Sti- triCL founds a new subspecies, aniycus, u))on a q from Santa Catharina with a fnni/cii.-<. 

 shortened tail-appendage (..abiiost in the shape of dyscnii''). 



D. dysonii Sndrs. (130 e). Above of a magnificently lustrous blue; in the j the bands of the wings di/.-^onii. 

 are only seen shining through the blue, showing through from beneath ; in typical dysonii less, but more in those 

 occuriing in the south of the range, Peru and Bolivia, and (according to Stichel) again in Panama. — psecas /'• 

 Sndrs. (oklros Fruhst.) (130e). The $ is beneath almost exactly like the cj, but of somewhat duller colours. 

 Above ic has also the marking of the cJ, but instead of the deep blackish blue colouring of the patches between 

 the transverse bands we notice a dull dark gre_\ with a ver\ faint bluish leaden-grey lustre, the tran.sverse bands 

 themselves being dirty whitish-grey. The butterflies are common at their habitats and often gather in num- 

 bers in the morning at drinking-places. The species is easily distinguishable from ■periander to which it is 

 not dissimilar, by the more distinct bands of th«^ upper surface and by the more complete, continuous, small 

 red anal band of the hindwino;.
