320 EHOPALOCEEA. 



Hab. Panama, Chiriqui (Bibbe), Bugaba (Champion), Veraguas (Arce). — South 

 Amekica, Venezuela to South Brazil. 



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

 Netrocoryne cwcutiens of Herrich-Schaffer, having compared it with the type in his 

 possession. With it he sends a specimen named Eudamus doriscus, Hew., which we 

 have no hesitation in pronouncing a female of W. ccecutiens. Hewitson's title has slight 

 priority, and must be employed. It has for its basis his own excellent figure in the 

 ' Genera of Diurnal Lepidoptera,' where, however, it is wrongly named Myscelus 

 sebaldus (Cramer). It is possible that Felder's Eudamus poreius, from the Eio Negro, 

 refers to the same insect, but we do not feel sufficiently confident on this point to use 

 his name. Should, however, it prove to be the same, which is the opinion of Plotz 6 , 

 the species will stand as Dyscophellus porcius (Feld.). 



Dyscophellus doriscus has not yet been found in our country beyond the State of 

 Panama, but it enjoys a wide range on the southern continent. 



The genitalia of the male have a long tegumen with a single terminal blunt point, 

 the harpes are simple lobes with rounded slightly serrate ends, the ventral edge is 

 slightly concave near the end. (See Tab. LXXVIII. fig. 18.)

Mr. Watson separated this genus, making Papilio phocus, Cramer, as the type, and 

 associated with it five other species, all of them belonging to the South-American con- 

 tinent. To these we now add two others. Five species occur within our limits, of 

 which N. phocus and N. ccepio range as far north as Guatemala. 



Nascus differs from Dyscophellus in having the outer margin of the primaries longer 

 than the inner margin ; the lower and middle discocellulars of the primaries are sub- 

 equal and in a straight line, which lies obliquely to the axis of the wing ; the recurrent 

 nervule starts from the third median segment before the end of the cell. There is no 

 trace of a radial to the secondaries.
