bracket-shaped markings are not only considerably enlarged but also proxinially bordered by a conspicuous 

 brown band. — hyacinthus Btlr. (67 a) inhabits Honduras, where, however, it is by no means common. Easy hycuinthHs. 

 to separate from montezuma 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 proxinially than in montezuma. 

 Clasping-organs descriped in the diagnosis of the species, crispitaenia Fruhst. is a $-form of hyacinthwicrispilaenia. 

 margined with brown-black almost to the middle of the wings, with large white median patches, running 

 out into a fine point distally. — pudicis Fruhst. is the local race from Nicaragua; much smaller the.n examples pudicis.

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

 Chiriciui and the state of Panama. We figure at 67 a the prevailing form from Costa Rica, \\-hich is labelled 

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

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

 proximal half of both wings, and limpida itself is based on an aberrant intermediate form. According to Godjiax 

 and Salvin, however, one might similarly erect a further series of names, as no two specimens a.re a,like. At any 

 rate, narcissus with its predominantly dark or violet-blue base leads over to peleides KolL, the commonest pclcidcs. 

 Morpho of Colombia, which is ^^anting in no consignment from there. The ^\'hite dotting of the submarginal 

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

 proxinially and even then only indistinctly. The light blue of the upper surface uniform, only with inappreciably 

 darker, slightly violet reflections over the basal part. $ with 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. hemispheii- 

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

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

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

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

 yellow rings which surround 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 Bch. macidaia. 

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

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

 ocelli, the paler submarginal lumiles 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 alwaj's rare in collections. ^ smaller, hindwing more broadly margined with black. Under surface with the 

 bands even paler than in maculata, ocelli 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. Accorduig to Dr. Hahxel 

 corydon is fond of feeding on fallen fruit and in particular 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 Bob. (69 b) peleus. 

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

 corresponds to narcissus Stgr. from Panama (Chiricpii), 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 rumiing parallel on tlie forewing with the distal margin. Under surface about as in insidaris 

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

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

 nose-sha^ied mark. Venezuela, co-type in coll. Frtjhstorfer. — insularis subsp. nov. A well defined island i7isularis. 

 race; o above showing 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. 5 above very similar to the o of cofrydon, 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 w hite interneural dots; which are larger than in peleides $ and more suggest 

 those of hyacinthus Btlr. The distinct j^roximal (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 brown parts of the median area of both wings, w Inch charac- 

 terize corydon, are absent. Accoi'ding to I-LwE common on Trinidad; both sexes collected by A. H. Fas.sl 

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

 nects corydon Guen. with peleides Koll.
