MORPHO. By H. Prtthstorfer. 355 



Avliere STArDisGEK, following Kiebv's Catalogue, had placed it. Hewitson's characterization "Upper surface 

 brilliant silvery blue, changing to pinli and distally to brilliant ultramarine blue, purple near the broMn distal 

 margin, which bears lunules as Avell as ej'e-spots, the latter only showing through faintly from beneath, habitus 

 nearest to aJiaxibia, but ^^•ith the colour of Morplio porfis {cytlieris)" is very apt. So is the extension of the 

 diagnosis in the description of the under surface, which is called "rufous or lilac-white clouded with rufous- 

 brown". The red-brown ceil bears in the middle a M'hit« (said to be silvery-white) band. Forewdng with four, 

 lrind^Ting with six ocelli; black-ringed ^^ith white piipils and standing in an unequal silver-white band. I have 

 a 5 before me from the fine William Morton collection in Lausanne; it shows small white, distally pointed 

 postdiscal and light vinous submarginal spots. The transcellular spot of the forewing in contrast to didius 

 short, narrow, only consisting of t^^o component parts. — alexandrowna Druce is probably the cJ to alexandra, alexan- 

 unless it belongs to a subordinate geographical race. (J greenish blue with light spot before the apex, below ^'''O'""^- 

 which are placed three faint blue-Miiite patches. Under surface dark chocolate-brown with grey scales near the 

 distal border. Ocelli three times as large as in menelmis. The type of alexandroivna is in the British Museum. 

 A o in coll. Frltistoefer from Pozuzo agrees Mith the description. — How far a further race from Peru, 

 assarpai Bob., can be kept associated \^ith alexandra-alexandrowna can only be proved by a comparison of the assarpai. 

 t^'pes. Three oo ^^ my collection from Pozuzo agree with Rober's description; they approach didius Hpffr. 

 in the somewhat lighter blue of the upper surface, and the basal area of the hindwing is less extended and more 

 sparsely scaled ^vith grey-green than in the o ^^ith dark blue upper surface, which I have referred provisionally 

 to alexandroicna. The clasping-organs of assarpai Bob. are about intermediate between those of the secondary 

 genitaha of J/, menelwus L. and J/, didius Hopffr. Valve somewhat larger and more markedly rounded than that 

 of menelaus. Uncus apparently somewhat longer, the thumb-like lateral projections decidedly larger, both in 

 their horizontal and vertical measurements. Uncus on the other hand more slender than that of didius, the 

 lateral lamellae less robust and the valve not so fully rounded. 



M. didius Hpffr. approximates to amatlionte Deyr. from Colombia in certain respects, particularly in its didius. 

 very broadly white-banded $, and the two species also agree in the lighter under surface. But the red instead 

 of yeUow bordering of the ocelli on the under surface establishes its connection with M. menelaus, though it 

 differs from the latter in the strildngly light basal area on the underside of the hindwing and the brilliant 

 silver-white decorations, and not least in the peculiar light blue opalescent reflections on the upperside of 

 both ^\ings. Morphologicgilly it differs less markedly from menelaus than in the scheme of colouring and mark- 

 ings, didius can, however, in general be separated from menelaus by the broader valve, almost fully rounded 

 distaUy and more regularly and delicately dentate than, in menelaus. Uncus with the lateral thumb-shaped 

 processes considerably widened, q above characterized by the already mentioned opalescent reflection, pecu- 

 liar to this species, somewhat suggesting M. octaviae, but at the same time brilliantly glossy as in aniathonte. 

 Distal border of both wings very narrowly black. Under surface of the forewing with three or four light vinous- 

 ringed ocelli. Hindwing with an apical eye-spot between the radials and two intramedian eye-spots, to which 

 is further added a smaUer accessory ocellus in the submedian interspace. Forewing with broad silver band and 

 greenish silver transcellular area. Hindwing with a silvery bronzy ornamental band proximally to the ocelli and 

 three detached wedge-spots of the same colour in the subbasal area. The distal region of both wings pow^dered 

 ^vith white or purple on a yellowish ground. Peru: Chanchamayo; probably also Bolivia. Judging from the 

 §2 in coll. SxArDrxGER those from Huayabamba have the most prominent white median band on the upperside 

 of the forewing, while those from Cuzco agree with the typical form from Chanchamayo. As the $$ from 

 Huayabamba also bear the most extended silver-white band on the hindwing beneath, they may be separated argentiferm. 

 as argentiferus subsp. nov. 



Addenda to the Morphids. 

 M. amphitrion p. 336. I have examples before me fromi Marcapata and Cuzco, Peru, with violet reflections on 

 the upper surface, azurita /orm. nov. asuriia. 



31. entropius p. 339. In coll. Staudinger there are ^^ from Pernambuco, above glittering mother-of-pearl colour, 

 beneath with more marked, more strongly white-pupilled ocelli. 



>I. argentlnus p. 340. There are (J^ from Uruguay in the Berlin Museum. 



Under M. patroclus p. 343 a form should be mentioned, macrophthalmus subsp. nov., from Bio San Juan, with gigantic macroph- 

 ocelU on the underside of the hindwing, bounded by a bright glossy greenish band. Type from Colombia in coll. Staudinger. thahnus. 

 microphthalmus suhsp. nov. is a further local race from Colombia. Type likewise in the Berlin Museum, with very small ocelli niicroph- 

 bordered by an indistinct whitish band. The submarginal stripes of both wings a peculiar grey with rosy tinge. thahnus. 



31. deidamia p. 347. praenestina subsp. nov. from Venezuela, from the Atahapo Yarita, discovered by Vraz. Above 'praenestina. 

 darker than 7ie/-»iion«, recalling neo/jtoerwiw, thus differing frora de'itZajniafl"6n. and erica i^ritfei., which have a violet base. Upper 

 surface of the forewing almost without white subapical patches; in this again more approaching the Surinam race. 



31. zephyritis p. 349. ? at the British Museum; above yellow-green, the apex of the forewing broadly black, the hind- 

 wing with sonae orange .spots and two black subterminal bands. 



31. aurora p. 349. 2 in coll. Ada>i and Fruhstorfbr; has on both wings a black-grey distal border, divided by yellow- 

 ish lunules and jjroximally bordered by larger grey-white patches. 



31. helena p. 3.51. From the Tarapoto come smaller cJcJ with reduced yellow median band, which moreover are copiously 

 du-sted with blue. Under .surface darker than in the name-type — chrysides subsp. nov. chrysides. 



31. cypris p. 3.51. chrysonicus subsp. nov. has a narrower median area on the forewing and more pronounced submar- chrysonicus. 

 ginal band on the hindwing than cypris from Colombia. Venezuela, collected by Vraz. Type in the Berlin Museum. 



31. melach«ilus p. 353. ?? occur with a remarkable flesh-coloured submarginal tinge on the underside of the hindwing. 

 From Sao Paulo, Amazons.
