Butler (1868) described Euptychia perfuscata and subsequently 
(1869) synonymized it to argante. We have not seen his speci- 
mens (which should be in the British Museum), nor any specimen 
definitely determinable under any of these names. The most recent 
discussion of argulus is by Weymer (1907, p. 202). The leading 
North American authority on Euptychia and its allies, L. D. Miller, 
advises us {in litt.) that he does not know the species, but from 
Cramer’s description and figure would place it near Y phthimoiches 
grimon. The partial synonymy of argante — argulus is thus: 
Papilio argante Cramer 1779 ( nec Papilio argante Fabricius 1775), De 
Uitland'sch. Kapell. 3: 19, pi. 204; type locality Surinam; type not 
investigated. 
% Papilio canthus ( nec Linnaeus 1767): Fabricius 1781 (partim), Spec. 
Ins. 2: 64 ( arganthe in synonymy) ; 1787, Mant. Ins. 2: 31; 1793, Ent. 
Syst. 3(1): 157. 
Satyrus argulus Godart 1821, Encyl. Meth. 9: 463, 488; type locality 
Surinam; type never existed (replacement name for argante ). 
? Euptychia perfuscata Butler 1868, Cat. Satyridae Br. Mus. : 18; type 
locality Para, Brazil; type probably in British Museum, not investigated. 
? Euptychia argante: Butler 1869, Cat. Diurn. Lep. Fabr. Br. Mus. 13. 
Cantheus , which is the unknown animal Fabricius confounded first 
with canthus and then with argante , usually appears in the synonymy 
of eurydice — canthus, but its only proper claim there is its mis- 
taken use in synonymy by Morris (i860). We have removed 
cantheus Godart from the synonymies of the other entities and 
regard it as a nomen dubium , presumably a species of Euptychia 
sens. lat. Its synonymy is: 
+ Papilio canthus ( nec Linnaeus 1767): Fabricius 1775 (partim), Syst. Ent.: 
486; 1781, Spec. Ins. 2: 64; 1787, Mant. Ins. 2: 31; 1793, Ent. Syst. 
3(1): 157. 
Satyrus cantheus Godart 1821, Encyl. Meth. 9: 465, 493; type locality 
“l’Amerique septentrionale” ; type not investigated, probably never 
existed. 
Godart’s description of cantheus erroneously cites Fabricius, 
“Species Insectorum” for “Mantissa Insectorum.” The name is 
misspelled “cautheus” in the heading on page 465. 
Taxonomic History: other names. — Gosse (1841) attributes the 
name Hipparchia transmontana to Say, but it does not appear in 
any extant work by that author. It usually appears in the synonymy 
of eurydice attributed to Gosse 1840. Apparently Gosse believed it 
was described elsewhere, since his “description” (1840, p. 247) is
