Melit.^a Arachne, n. sp. 



Female. Expands 1.6 inch. Upper side fulvous inclining to 

 ochrey yellow, crossed by common black lines; hind margin edged by 

 a crenated line on which rests a series of large spots, of paler shade 

 than the ground color, edged above by a second crenated line ; on 

 primaries, these spots are somewhat indistinct; crossing the disks are 

 two heavy, tortuous lines, enclosing with the black nervures, pale spots ; 

 on arc of primaries a subovate spot enclosed by black; in cell a wavy 

 line and two near base; secondaries have the base and abdominal 

 margin black ; in the upper part of cell a deep falvous sinus. 



Under side of primaries yellow fulvous; the margins edged by a 

 crenated line on which is a complete series of large white crescent spots, 

 edged anteriorly by black, beyond these a row of indistinct whitish patches 

 followed by a double curved line of black spots and faint lines indica- 

 ting the spots and marks in the cell above. 



Secondaries have also a marginal line and a series of large yellow 

 crescents, above which is an ochrey band and a second of whitish, the 

 latter broad, edged on both sides by broken black lines, and enclosing 

 in the middle at either extremity parts of a third similar line ; beyond 

 this another band of ochrey yellow which projects a broad dentation 

 into the next or third white band; this latter is heavily edged onboth 

 sides by black, and is followed by the third band of yellow; next base 

 a white patch. 



Palpi ochrey yellow ; antennae brown above^ yellow beneath; club 

 black, tip ochrey.

This species is closely allied to M. minufa, Edwards, of Avhich a 

 single male was described in Proc. Acad. Nat. Sci. Phila., 1861, and I 

 am not certain that it may not prove to be the female of that species. 

 Unfortunately the original specimen is not in this country nor accessi- 

 ble. I preserved a coarsely executed lithograph of it, from which the 

 female above described differs somewhat, but perhaps not materially. 



This, or these two species differ from any other North American 

 Melitseas with which I am acquainted, and belong to the group of 

 which Cinxia (^Eiiropeaii) is the type.
