C. oeaipus, a very rare, iiisignificant-looking species, splits up into two local races: oedipus Stick, oedi-pm. 

 .(J: forewing above "n-liitish, costal margin slightly darkened with grey-brown, broadly in the cell, distally 

 more narrowly and before the fork of the last subcostal veins running out into a point. The veins in the 

 anterior median area finety dusted with brown. A slight bluish tinge below the cell. The light band be- 

 liind the cell indistinctly defined prosimally, anteriorly strengthened by a nearly saffron-yellow patch. The 

 distal area fairly uniform black-brown, the band near the margin of the wing only quite faintly indicated. The 

 basal area of the hindwmg grey-blue to about the end of the cell, obliquely bordered posteriorly, this part as 

 well as the hindmargiiial area nearly to the anal angle with blue reflections. Distal margin strongly undu- 

 late. 2 larger, costal area clouded with deeper brown, the bluish tinge below the cell somewhat increased, t 

 the light transverse band behind the cell broader and more distinct, the veins very strongly dusted with 

 brown, the spots in the anterior part of the dark brown distal area distinct, the light band before the distal 

 margin better expressed, undulate, slightly dentate. The blue basal area of the hindwing more truncate, 

 with a silky grey-blue gloss, at an oblique angle of light iridescent, the iridescence, however, not extend- 

 ing so far towards the hinder angle as hi the ^. nocturna Stich. is a subordinate form, in the ^ of which noduma. 

 the forewing is almost uniformly darkened with smoke-brown as far as a somewhat lighter transverse stripe 

 beyond the cell, the blue gloss restricted to the proximal part of the terminal area. The blue basal area of 

 the hindwing somewhat reduced. Forewing of the $ with stronger and more extended blue gloss and duller 

 but more distinct dentate band near the distal margui. Ground-colour in general even darker brown. Transi- 

 tions occur to the tj'pe-form. Colombia. — • fruhstorferi Stick. (64 c) is in the ^ somewhat smaller on an fmhstorferi. 

 average than the preeeeding; forewing somewhat more rounded, costal area lighter brownish, transparent, 

 but broader and entirely filling up the end of the cell. The confused figures in the cell beneath distinctly ■ 

 visible above, the light transverse band behmd the cell better defined, the bluish dusting below the cell 

 somewhat more copious and extended to the inner boundary of the transverse band, which shows tlnrough 

 from the underside. The band before the distal margin likeAvise somewhat better expressed. Hindwing uniformly 

 rounded, distal margin only quite weakly undulate. The blue basal area viewed from above with a silky 

 gloss, in an oblique light -with blue reflections for about the same extent as in typical oedipus. Under surface 

 with the posterior eye-spot relatively larger. Costal area of the forewing in the $ likewise darkened as far 

 as the Light median band, strongty transparent, the blue suffusion behind the cell more distinct, also extended 

 on to the anterior part of the cell, but there weaker. The band behind the cell anteriorly strongly dentate, 

 posteriorly feebly curved, the spots in the costal part of the distal area very distinct, the band before the distal 

 margin almost whitish yellow, its boundary strongly dentate, the distal margin itself pale ochre-brown. The 

 blue basal area of the hindwing reaches distally to beyond the end of the cell; viewed from above strongly , 

 glossy, in an oblique light with bright blue reflection. Distal margin of the hindwing likewise very little undu- 

 late and somewhat more copiously dusted with grey-white. Under surface as in the (J, except that the dark- 

 shaded band in the middle of the forewing is prolonged to the submedian and the two undulate or dentate 

 bands in the distal area of the hindwing are very sharply expressed. Honduras, probably also in other parts 

 of Central America. 



^^ C. olleus is a protean species which seems to be distributed from the Andes to Mexico, south- 



wards reaching Bolivia, but on the Atlantic side apparently not extending beyond Venezuela. Six or seven 

 known races, some of which are not very sharply differentiated. — oileus Fldr., the name-type, came from oileus. 

 Venezuela. Forewing in the ^ almost brownish grey, posteriorly somewhat lighter, markings of the under 

 surface showing through. The band before the distal margin washed-out, but always remaining visible. The 

 rest of the marginal area distaUy pale black-brown, the dark spots in the apical area distinct, the light band 

 basally more or less distmctly projecting along the veins; the blue gloss below the cell weak, often only 

 perceptible in an oblique light. 5 larger, wmgs smoke-brown to the narrow transverse band, basal part to 

 near the costa and to the posterior part of the cell slightly suffused with bluish, rather strongly glossy, the rest 

 as in the ^, but with the band before the distal margin more distinct. Under surface with moderately wi- 

 dened whitish band behind the cell of the forewing. Hindwing with distinctly developed dentate band in the 

 distal part. The submarginal lines on the underside of the forewing in both (^ and $ shortly and regu- 

 larly dentate. Venezuela. — ■ scamander Bdv. has the apex somewhat produced. Costal area darkened as far scamander. 

 as the median, the anal area relieved with wliitish grey; only at the base a faint blue gloss. Transverse 

 band as a rule rather broad, anteriorly narrower, bone-white, quite faintly tinged with yellow. Markings of 

 the under surface showing through above. $ larger, wings more rounded, transverse band widened, especially 

 beneath, its bovmdary-line curved distad. Anal area as far as the transverse band somewhat darker and more 

 copiously shot with blue. Distal margin of the hindwing somewhat less undulate, the proximal area viewed 

 from above somewhat more distinct but paler blue-grey. On the under surface the undulate band behind the cell 

 of the hindwing especially sharply expressed, with metallic black-blue gloss. In both sexes the lines near the 

 distal margin on the underside of the forewing less regular and more shallowly curved than in the tjrpical sub- 

 species. Central America (Costa Rica, Panama [?], Mexico [?], Guatemala [?]). — ■philademus Stgr., from i\ie pMlademus.

 zuela, but is darker, hindwing above more strongly shot with greenish blue. ^ under surface with deep brown
