12. EuEIDES ZORCAON, tlOV. Sp. 



Male. Upper surface : fore wings black ; four transverse bands, of which the 

 apical is composed of four oblong spots ; the second crosses the cell near its 

 extremity, and consists of two dashes above the cell, an irregular nairow one 

 within it, and a long, gradually tapered stripe below it. Both these bands are 

 entirely dull ochraceous ; the third rises from the base, follows the first median 

 veinlet to its middle, up to which point it is orange tawny, is then suddenly 

 turned above this nervule, and runs nearly to the outer margin ; this latter 

 portion is ochraceous, and is much compressed near its lower extremity ; the 

 fourth is orange tawny, and occupies the length of the inner margin below the 

 subniedian vein. 



The hind wings are black, with a broad central orange tawny belt, through 

 the middle of which passes a black band, sometimes united with the outer 

 border towards the apex, and usually narrowed towards the abdominal mar- 

 gin ; there is a row of indistinct spots on the outer margin, especially promi- 

 nent near the anal angle. 



Under surface; disposition of fore wings' markings remains the same, but 

 they are much reduced, with a consequent increase of the black and blackish- 

 brown areas ; the costa has a short basal stripe of orange tawny, and there 

 are three or four small white apical spots. 



Secondaries chiefly as on the upper side ; there is an additional transverse 

 stripe, ochraceous, running from the base nearly to the outer angle, and marked 

 on its under side at its origin with a white point; two rows of well-defined 

 white points on the outer margin, of which the interior, numbering fourteen, 

 are the largest; the outer row contains fifteen. Expanse 3 3J inches. 



Ilab. Mexico (near Vera Cruz); Coll. W. H. Edwards. Honduras, Guate- 

 mala; Coll. Tryon Reakirt. 



As' may be seen from the foregoing description, this pretty species bears 

 considerable resemblance to Eueides Cleobxa, Huba. 1 find, however, from the- 

 examination of a large number of specimens of both, that their differences are 

 always constant, and such as warrant tbe creation of a separate name for the 

 designation of this form, which, although doubtless a local race of the Cleobsea, 

 has become perfectly segregated from the older type ; I have seen no interme- 

 diate varieties. 



13. ACR/EA ORIZAVA, HOV. Sp. 



Upper surface glossy bluish-black; primaries with a large transverse yellow 

 spot, divided by the median vein and its branches into five parts. 



Beneath pale ochreous, with the nerves, and streaks between them black ; a 

 very large central yellow patch on the fore wings, crossed only by black veins ; 

 base of the fore wing black, that of the secondaries more yellowish. Expanse 

 2-25 2-50 inches. Body and antennae black. 



Hab. Mexico. Coll. Tryon Reakirt. 



Closely allied to the A. leucomelas, Bates, of Guatemala, of which it may be 

 regarded as a more northern modification. It differs chiefly, but constantly, 

 in size and number of the yellowish spots of the primaries. 



14. Agratjlis huascdma, nov. sp. 



Upper surface bright orange-brown; markings of primaries as in .4. Juno, 

 but much narrower, more clearly defined, and always deep black. Second- 

 aries with a broad terminal border, containing a series of orange-brown lunules. 



Underneath, the markings present no perceptible difference from those of 

 Juno, but the shades are darker, the silver spots more clearly defined, and the 

 base of the fore wings much more reddish than in that species. Expanse 2:50 

 to 2-*75 inches. 



The outer margin of the primaries is not so deeply sinuate, nor are the in T 

 dentations of the secondaries so prominent as in Juno.
