by a fulvous lunule ; the lower half of the inner line is bordered interiorly by 

 a narrow black line, and the enclosed spaces and outer margin below the 

 upper tail are filled with black patches ; there are four white lines, two from 

 the costa, one from the base, and one from the inner margin, all converging 

 towards and uniting above the fulvous lune ; the first and last are edged pos- 

 teriorly by a narrow black line, and the third and fourth are broadly inter- 

 rupted by the submedian vein. Expanse 1*5 inches. 



Body above glossed with greenish blue, beneath brownish ; antennae black 

 with white annulations. 



Hab. " Mexico (near Vera Cruz)." Win. H. Edwards. 



32. Nisoniades Me.ticanus, nov. sp. 



Upper side brownish black, a submarginal row of pale brownish spots on 

 both wings ; on the primaries an interior tortuous row of nine spots, of 

 which the first five are pure white and well defined, the others are sometimes 

 obsolete ; a white discal spot. 



Underneath paler, glossed with purple at the base of the primaries ; their 

 apex and the secondaries shining olivaceous brown ; a row of five white spots 

 runs from the costa of the primaries, and a white discal spot ; the veins of the 

 secondaries are prominently outlined in dark velvety brown ; expanse 1 inch. 

 Fringe brown. 



Body and antenna? as in N. Catullus. 



Hab. " Mexico (near Vera Cruz)." W. H. Edwards. 



A neotropical representative of our own Catullus. There are, in my col- 

 lection, several new and allied South American forms, which replace this 

 species upon the Amazons, and further southward ; they will be described 

 hereafter. 



33. Pykgus montivagus, nov. sp. 



Upper side dark olive brown ; primaries a marginal row of minute white 

 spots, sometimes obsolete, followed by a submarginal series of larger ones ; an 

 irregular transverse, maculate band, composed thus : three oblong dashes 

 from the costa, preceded by a small dot, then three rounded or subquadrate 

 and smaller spots, and following, two large subquadrate patches, the last 

 usually presenting a brown indentation on the outer side ; a large quadrangu- 

 lar discal spot, between which and the third, fourth and fifth of the transverse 

 band are a small dot, and two narrow streaks ; above the discal spot are one 

 or two small dashes, and below it two conical spots; the outer half of the 

 co-ta has four or five linear spaces upon it. 



Hind wings with a marginal and submarginal row of rounded spots, and a 

 mesial baud of five or six oblong bars ; all the markings of the upper surface 

 are white. Fringe white, cut with black at the end of the nervures. 



Under surface primaries have the markings of the upper side, repeated and 

 enlarged ; ground color pale olive brown. 



Secondaries pale olive brown, lighter towards the base ; a curved black 

 line on the projecting shoulder, terminating in an enlarged knob; two trans- 

 verse white maculate bands ; one near the base of three spots, edged pos- 

 teriorly with brown lines, the other is mesial, of irregular outline, and 

 bordered with black lines on both sides ; a submarginal and a marginal 

 series of white lunes, surmounted by darker lines ; abdominal area white, 

 with a dark maiginal line and projecting shadow at the anal angle. Ex- 

 panse 1-20 inches.

Most probably an alpine modification of the common Pi/rgus oileus. 



34. Pyrgus macaira, nov. sp. 



Male. Upper surface pearly- white, apex of primaries strewn with dark 

 brown atoms, with indistinct traces of an interior submarginal line ; base of
