prominence, the inner angle of which is slightly produced : this projection forms the 

 outer edge of the dorsal fissure. 



4. Eudamus albimargo. 



Thymele albimargo, Mab. Bull. Soc. Ent. Fr. 1875, p. ccxiii 1 . 

 Goniurus albimargo, Mab. & Vuill. Nov. Lep. p. 37, t. 5. f. 2 (1891) \ 



E. dorysso persimilis, sed margine posticarum albo multo angustiore, limbo suo interno baud irregulari, color© 

 fusco alarum ad basin caudse intrante. 



Hab. Guatemala, Yzabal, Polochic Valley (F. D. G. & 0. 8.) ; Panama {fide 

 Mabille l ), Chiriqui, Veraguas (Arce).— South America, from Colombia to Brazil x 2 ; 

 Jamaica. 



This species was separated from E. doryssus in 1875 by Mons. Mabille, his descrip- 

 tion being based upon a specimen stated, with doubt, to have come from Panama. In 

 their illustrated work the species is ascribed to Brazil. According to our determina- 

 tion both places are within the range of the species, which extends sparingly from 

 Guatemala to Brazil, and we possess specimens from a few localities scattered over this 

 wide area. 



The differences between E. albimargo and E. doryssus are slight but fairly constant, 

 and the two forms, for the present at least, had best be kept separate. 



5. Eudamus chales, sp. n. (Tab. LXXV. figg. 2, 3.) 



E. dorysso proximus, sed alisanticis fere immaculatis, puncto costali ad apicem byalino tantum notatis, posticis 

 fere ut in E. dorysso : subtus (margine posticarum externo albo excepto) immaculatis fuliginoso-nigris. 



Hab. Mexico, Acapulco (H. H. Smith). 



We have two male specimens of this species, which, though allied to E. doryssus, 

 differ in having immaculate primaries, the median diaphanous band being wholly 

 absent, and the subapical spots near the costa reduced to one or two obsolete points. 

 In the interior outline of the white margin of the secondaries, E. chales resembles 

 E. doryssus rather than E. albimargo ; the tail is much shorter though pure white. 



6. Eudamus nigricauda. 



Goniurus nigricauda, Mab. 



Ali a murinis, anticis fascia transversa angusta fere ut in E. albimargine, punctis quinque subapicalibus in linea 

 recta positis ; posticis immaculatis, cauda concolore, ciliis a margine externo medio ad angulum apicalem 

 albido : subtus ut supra, posticis saturatioribus fasciis valde indistinctis nigris notatis, margine externo 

 ad angulum apicalem cum ciliis attingente albis, ciliis ad caudam et angulum analem omnino fuscis ; plica 

 costali obvia. 



2 mari eimilis, plica costali nulla.
