 Goniurus stylites, Plata, Bull. Soc. Imp. Mosc. lv. No. 3, p. 5 (1880) 3 . 



Alis murino-brunneis ; anticis fascia mediana tripartita costam haud attingente, macula discali ultra earn 

 angusta et punctis quatuor subapicalibus in linea obliqua positis navo-hyalinis ; posticis penicillo fusco, 

 ciliis albidis : subtus anticis fere ut in E. unclulato, area interna ochraceo-albida ; posticis fasciis duabus 

 irregularibus fuscis notatis ad costam convergentibus, maculis duabus basalibus ad costam, inter fascias 

 purpureo-fuscis albido atomatis ; plica costali nulla. 



Hah. Panama, Chiriqui (Bible, in mus. Staudinger). — Colombia (apud Mabille & 

 Vuillot) ; Amazons Valley ; Brazil (apud Plotz). 



We retain this name of Herrich-SchafTer's for a Chiriqui specimen in Dr. Stau- 

 dinger's collection, which has been kindly lent to us for examination. M. Mabille, 

 having no doubt compared it with the type, has named it as a subvariety of E. stylites, 

 a species he deems, in his work above quoted, somewhat variable in its markings. 

 Plotz is the only writer who refers to the tuft of hairs on the hind wings above ; but 

 he does not mention their colour, which is of importance in discriminating these closely- 

 allied forms. The Chiriqui specimen has this tuft brown, like the rest of the upper 

 surface of the wings, as in E. undulatus. Others have it tawny. 



GONIUBUS. 



Goniurus, Hiibner, Verz. bek. Schm. p. 104 (1816) ; Watson, P. Z. S. 1893, p. 20. 



Mr. Watson keeps this genus separate from Eudamus, but its distinctness is open to 

 question. The neuration of G. coelus, the type of Goniurus, is almost exactly like that 

 of E. proteus, the type of Eudamus. The third median segment is rather longer in the 

 former, but this is of little importance ; the antennae, palpi, and legs being alike in both 

 forms. There remains only the shape of the secondaries, which are not tailed to the 

 same extent in G. coelus as in E. proteus ; but this, again, is a variable character within 

 the limits of the former species. 



G. coelus is the only species of Goniurus according to Mr. Watson ; but as G. talus 

 agrees in every structural feature (including, to a great extent, the male genitalia) with 

 G. coelus, we remove it from Epargyreus and place it here.

Alis murinis ad basin cum corpore toto viridi lavatis ; anticis maculis quatuor fascia transversa formantibus, 

 macula ultra eas et punctis quatuor costalibus ad apicem in linea perobliqua positis ochraceo-hyalinis : 

 subtus pallidioribus viridi vix lavatis ; anticis ut supra, posticis purpureo tinctis et linea discali a vena 

 costali ad venam submedianam extensa nivea, ciliis pallide fuscis ; plica costali obvia. 



£ mari similis, sed plica costali nulla.
