POTAMANAX. 393 



2. Potamanax melicertes, sp. n. (Tab. LXXXVI. fig. 4.) 



P. pammeni affinis, sed fascia alarum communi alba usque ad costam anticarum extendente, contra in posticis 

 marginem internum haud approximante. 



Hab. Panama, Chiriqui (Trotsch, in mus. Staudinger). 



Dr. Staudinger has lent us a specimen of this species under the name Leucochitonea 

 unifasciata, Feld. ; but it differs from that insect by the absence of the spots in the 

 apex of the primaries, and the rufous-orange inner edge to the white band on the 

 same wings. From P. pammenes it differs as noted above. 



3. Potamanax caliadne, sp. n. (Tab. LXXXVI. figg. 5, 6.) 



Alis nigricantibus ; anticis fascia mediana venis nigris octopartita alba, maculis duabus, una rami mediani 

 primi utrinque et margine interno ad medium indistincte aurantiacis, area discali fusco maculato, 

 punctis submarginalibus quoque fusco- albidis ; posticis plaga magna mediana alba costam attingente, sed 

 angulo anali baud approximante : subtus fuscis, fascia communi lata alba, maculis submarginalibus albis ; 

 anticis area apicali pallide fusco variegata, posticis ad basin glaucescentibus ; palpis subtus griseo-albidis. 



Hab. Costa Rica, Cache (Sogers). 



We have only one specimen of this species, which was captured at Cache in Costa 

 Rica by Mr. H. Rogers. The species is allied to P. thestia and P. latrea : from the 

 former (taking Hewitson's " male" as the type) it differs in having the dark portions 

 of the primaries more distinctly variegated, and the white patch of the secondaries 

 much larger, as well as in other minor points ; and from the latter it differs in the more 

 definite band of the primaries and its white colour, the patch of the secondaries being 

 much wider and confined to the inner area of the wing, not approaching the inner 

 margin. 



4. Potamanax latrea. 



Leucochitonea latrea, Hew. Ex. Butt., Leucochitonea, ii. f. 14 \ 



Alis fusco-nigricantibus, fascia communi mediana albicante in anticis fuscescentiore et venis octopartita, area 

 discali indistincte pallide fusco variegata, punctis submarginalibus indistincte fuscis, in posticis integra a 

 costa usque ad marginem internum extendente : subtus fuscis, fascia communi multo latiore in posticis 

 albicantiore et fere integra ; posticis ad basin glaucescentibus. 



Hab. Nicaragua (Mus. Brit. 1 ). 



The single specimen in the Hewitson collection in the British Museum is the only 

 one we have seen. 



5. Potamanax xantholeuce. (Tab. LXXXVI. fig. 7.) 



Ephyriades xantholeuce, Mab. Le Nat. x. p. 242, f. 5 (1888) l . 



Alis brunneis, fascia irregulari communi obscure aurautiaca, in anticis venis quadripartita sed costam baud 

 attingente, in posticis integra costam attingente sed margine interno remota, area discali indistincte nubi- 

 losa : subtus ut supra, fascia communi multo latiore, in anticis integra costam attingente, posticis ad basin 

 et ad marginem internum glaucescentibus. ._
