season. One form of tin- rainless period in January, being somewhat faded heneath, and specimens with moic 

 pronounced markings, of the rainy months (June, July), ^'enezuela. — fumida Bth. is beaten in size by Irn/iiin. iumiiln. 

 the narrower hingitudina! band of tiie forewings being moi'e acutely angled, too. From Eastei-n Peru. — wil- /'■ilhc/iiiiiui. 

 helmina Fmhst. Smaller than inniiin DM. and Hen\ from \'enezuela, above darker, the ochreous longitudinal 

 band more strangulated on both the surfaces, considerably narrowei-. Under surface: forewing with larger' 

 white spots. Hindwing with much narrow er' \\ hite maculae. Oblic[ue liarid of the forewing darker-, nu)r e narrdw ly 

 confined. Hindwing in the subanal region lighter-, mcjre spotted in yellow. Bolivia. Clasping organs of the 

 habitus of A. tifuht. entirely different fr-om the groups of .4. isis and .4. erotiti. YnWe remarkably short with 

 2 or 'i exterior teeth, but without any ventr-al orres. Clunii-iila high, narr-ow . Uncus plain. Poirrt of penis rrot 

 shai'ply bent upwai-ds. but nearly straight. 



A. irma irrhal)its Per-u and Bolivia as irnia Fndi.sl. (lOSc). UpjH'r- surface similar- to horm.-i Btlr. arrd inmi. 

 irminn Dhl., the ochreous oblicpie band, however-. j)roximally more wiflening arrd the distal spot at the anterior- 

 median nearly isolated. Under surface: band of the forewing steeper than in horens. Hiridwirrg more roundish, 

 with 3 whitish-violet median tr-ansverse bands, the outer one of which projects the furthest into the wing-t-entre. 

 wma thereby approximates irminn Dhl. fr-onr w!ri(-h it is, however, immediately distirrguishable by the subdued 

 colours of the bands being, besides, also narrower. Peru: Pozuzzo, reachirrg an altitude of 2000 m near Cara- 

 baya. — nadja Fruhst. Ochreous band of the forewings more extensive than in irma. Hindwirrg pierced by a nadja. 

 magnificent black submarginal band appearing orrly obsolete in specimens from Peru. Under surface: yellowish 

 oblic[ue band of the forewings broader, lighter, all the bands of the hirrflwings being also rnor-e violet and broader- 

 Bolivia. — Genitals considerably differentiated from those of A. iiiiihiu. \'alve entirely more slerrder-, without 

 any spines, but with very long bristle^. Point of penis curved. 



A. boreas. An Andine species and distributed, from Colombia to Bolivia, riporr 4 ar-eal forms: espe- 

 cially beneath most variable in the extent of purple or violet parts with metallic lustre. — tizona Fldr. (108 d) thona. 

 has two distinct small yellow preapic-al s])f)ts on the forewings. Fassl found the V on the Ujiper Rio Xegt-o. 

 the ur\der surface of which is more fallow, the yellow area of the forewings broader, likewise paler-. — tizo- I'Ltonhlrx. 

 nides Fmhst. (lOSd) beats tizona in size: with roundish hirrdwings and indistinct reddish-brown apical spots, 

 very broad and distally only faintly dentate subapical band of the forewings. Under surface of hindwings 

 traversed by a narrow brown postrnedian band. West Colombia and Cundinamarca. — opheltes sub-sp. nov. ophrllrx. 

 was recently again discovered in Pananra from where Godman had figured it already as A. tizona. Band of the 

 forewings above distally only unnoticeably dentate. Under surface with broader brown postdiscal band than 

 tizonides and reduced transcellular stripes. — verenda .subsp. nov. (108 c) differs from tizona by darkened and verciida. 

 proximally deeper incised oblique band of the forewings. The under surface exhibits a narrower transverse 

 band of the forewings and more whitish edging of the hindwings. Peru, common, preferring altitudes of 1500 

 to 2000 m. — boreas Btlr. equals .4. irma (108 c) in size; under surface lacking the violet hue, the oblique horra.-.: 

 band of the forewings sharply set off, paler than in verenda. Bolivia, also on the Upper Rio Negro. 



A. ximena Fldr. The most imposing species of the group with ochreous area on the forewings, which .rhufiia. 

 expands similarly as in .4. mesentina (108 e) and from which three subapical maculae extend in the shape of 

 a band as far as to the costal margin. Under surface resembling that of tizona Fldr. but without the 

 transverse band running through, which is leplaced by two rows of roundish light spots. Peru: Pozuzzo, 

 rrot i-are. 



A, salmoneus irduxbits Central America from Guatemala, and Colombia. We nuxy separate 2 geo- 

 graphically split branches. — emilia Fruhst. (108 e), a smaller form with more imposing grej'ish-violct bands ciniHa. 

 than salmoneus (108 e) exhibits. Guatemala to the Cauca Valley. — salmoneus Btlr. { 108 e), a more magnificent .•<almoticiis. 

 race with more streak-like bands orr the under- sur-face. Eastern Colombia also fr-om ( 'undinamar-ca in the Tring 

 Museum. 



A. colada Fldr.. an extremely rare species of whii-h orrly the type is krrown and which I was err- ciitadd. 

 abled to examine thanks to the obligingness of the officials in the Tring-Museum. Upjrer- surface about 

 similar to that of ■■ialrnoneus {\()9, e), while the under surface approaches more boreas Btlr. and still more .4. 

 irma Fruhst. (108 c). Bogota (Colombia). 



A. saundersi, the most luxuriant species of the series with lir-ownish-yellow bands. The under surface 

 is most imposing with its magrrificent r-eflections of silvery brightness reminding us of Argynnis adippe and 

 being unparalleled among the Adelpha. According to Weeks there is said to be a local race in Colombia with 

 white drops on the under surface instead of those of metallic lustre. — saundersi Hew. is described from Ecuador .saumlrryi. 

 and also found in Colombian districts, where Fas.si. took single specimens near Pacho at an altitude of 2200 m. 

 — leutha siibsp. nov. stays smaller than helepecki (108d) arrd has a lighter yellow under surface, verj' mu(-h IckIIki. 

 reduced reddish-brown longitudinal bands and obsolete silver-spots of the anal part of the hindwings, Peru, 

 Cushi from 1820 m. Type in the Tring-Museum. — helepecki Weeks (108 d) is only lying before us from Bolivia, hrlrpn-ki. 

 The $ was collected by Fassl near Coroico, It differs from the J only by a more pr-onounced black spotting 

 on the under surface of the hirrdwings.
