bracket-shaped ma,rkings a.re not only considerably enlarged but also proximally bordered by a conspicuous 

 bro'wn band. — hyacinthus Btlr. (67 a) inhabits Honduras, where, however, it is by no means common. Easy hyacintlms. 

 to separate from moniezmna by its larger size and more pointed forewing, hyacinthus is further noteworthy for 

 the lighter and more glossy blue on both wings. The black distal border as a rule smooth at its proximal edge; 

 yet examples also occur with the distal border even more strongly dentate proximally than in montezuma. 

 Clasping-organs descriped in the diagnosis of the species, crispitaenia Fruhst. is a ^-form of hyacinthus crispHaenia.

 oldest name, we include here the polymorphic series of individuals which inhabit Costa Rica, the Volcan de 

 CMriqui and the state of Panama. We figure at 67 a the prevailing form from Costa Rica, which is labelled 

 hydorina Btlr. in the British ]Museum and is characterized by having the basal half of both wings mostly dark hydorhia. 

 brown, marinita Btlr. designates examples with the blue median band of the hindwing reduced, or occasionally mariniia.

 proximal half of both -ndngs, and limpida itself is based on an aberrant intermediate form. According to Godman 

 and Salvt^v, however, one might similarly erect a further series of names, as no two specimens are alike. At any 

 rat«, narcissus with its predominantly dark or violet-blue base leads over to peleides Koll., the commonest peleides. 

 Morpho of Colombia, which is wanting in no consignment from there. The AA'hite dotting of the submarginal 

 area of peleides is simpler than in the northern races, the distal border always narrow, deep black, rarely dentate 

 proximally and even then only indistinctly. The light blue of the vipper surface uniform, only mth inappreciably 

 darker, slightlj- violet reflections over the basal part. $ wdth two rows of white submarginal dots on the forewing, 

 of which the proximal also are rounded, not elongate as in limpida. Under surface of the (J (J, as already men- 

 tioned above, deepest in colour, almost black-brown with grey-white anteterminal lines. According to Fassl 

 peleides only occurs in Western Colombia, from Bogota to the Pacific coast, whilst achilles is only found to the 

 east, and the two species seem to be separated from one another. — Egg of the size of that of achilles, hemispheri- 

 cal, with a shght basal depression, greenish yellow, dully transparent, surface rough, not glossy. — cortone subsp. nov. cortone. 

 differs from normal peleides in its smaller size and in having the blue gloss much lighter, particularly distally, 

 and the black distal border of both mngs more extended. The under surface is characterized by its almost 

 entirely white subterminal lines, the light bronze-green gloss of the proximal bordering of the ocelli and the light 

 yellow rings which surroimd them. Moreover the vermilion lunulate spots of the hindwing stand out more 

 distinctly and might even be described as being as broad again as in peleides. Colombia. — maculata Rch. macidata. 

 seems to be the most southern local form yet discovered. It may be easily known by the whitish blue upper sur- 

 face, relativeh' narrow border and especially the lighter underside, with broader grey-white band bordering the 

 ocelli, the paler submarginal lunules and the widened anteterminal patches. Ecuador. — corydon Guen. is the corydon. 

 most eastern offshoot of the collective species and was described from Venezuela as long ago as 1859, but is 

 still always rare in collections. ^ smaller, hindwing more broadly margined with black. Under surface with the 

 bands even paler than in maculata, oceUi quite small, similar to those of pudicis Fruhst. Transverse bands in 

 the cell of the forewing still broader than in maculata. The $ is not yet known. According to Dr. Hahnel 

 corydon is fond of feeding on fallen fruit and in particvdar cannot resist sugar-cane which has been split open 

 and spread out on forest-paths, though it is often only worn specimens that visit the bait. — peleus Rob. (69 b) peleus. 

 is an interesting, well differentiated form either belonging to the rainy season or to the mountains ; it some^vhat 

 corresponds to narcissus Stgr. from Panama (Chiriqui), with the basal part of both wings darker blue, shot 

 with intensive, nearly violet reflections. The black marginal area of both wings narrower, not widened 

 apically, thus running parallel on the forewing with the distal margin. Under surface about as in insular is 

 Fruhst. from Trinidad, without the whitish shade proximally to the row of ocelli. The band accompanying the 

 ocelli not white, but greenish as in corydon, not interrupted in the median part, but joined to a projecting 

 nose-shaped mark. Venezuela, co-type in coll. Frtjhstorfer. — insularis subsp. nov. A well defined island insularis. 

 race; ^ above .shoAAing more resemblance to peleides cortone Fruhst. than to the neighbouring Venezuelan 

 race, the black distal border of the wings, particularly of the hindwing, considerably narrower, without sub- 

 marginal bordering of small red spots. ? above very similar to the (J of corydon, but with broader black border 

 to both wings. The transcellular region about as in peleides $, but deeper violet-blue. Between the costal 

 and the lower median are placed five white interneursi dots, which are larger than in peleides $ and more suggest 

 those of hyacinthus Btlr. The distinct proximal (second) submarginal row of dots of peleides is wanting. Hind- 

 wing with quite small reddish patches. The blue area deeper blue than in peleides, with brilliant violet reflection; 

 under surface considerably darker than in corydon, resembling that of cortone. The foreground of the ocelli 

 densely dusted with greenish, the whitish and light browii parts of the median area of both wings, which charac- 

 terize rjyrydon, are absent. According to Kaye common on Trinidad; both sexes collected by A. H. Fassl 

 at the Maracas Fall. From the Sierra Nevada Godman and Salvin record a peleides form, which perhaps con- 

 nects corydon, GvAn. with peleides Koll.
