GENUS CASTNIA AND SOME ALLIED GROUPS. 189 



nigricante lateribus segmentisque 5 apicalibus subtus fulvis ; tborace subtus albido 

 vario ; antennis albidis. Long. corp. unc. If. Expans. alar, antic, unc. 4^. 

 Sab. Amazonia. In Mus. Hopeiano Oxonise (olim Saunders). 



This species is closely allied to C. cycna, but bas tbe fore wings less rounded ; tbe 

 arrangement of tbe cell and brancbes of tbe postcostal vein agrees witb tbat of 

 C. cycna. 



60. (5) Castkia ecttadoria. (Plate XXXII. fig. 6.) Alis anticis oblongo-ovatis apice 

 rotundatis ; e basi ultra medium obscure lutescentibus, apice lato fusco ; cellula 

 basali fusco marginata, macula media rotunda subcostali, striga obscura media, 

 alteraque majore marginis interni fuscis; alis posticis obscure fulvis nebula magna 

 ex angulo anali versus medium alas extensa fimbria que fuscis ; corpore fusco ; collari, 

 fascia media transversa thoracis, lateribusque abdominis lutescenti-albidis ; antennis 

 lutescentibus : alis subtus magis rufescenti-fulvis, apice fusco, posticis stria tenui 

 transversa subbasali fusca. Long. corp. unc. lj. Expans. alar, antic, unc. 3^. 



Sab. Ecuador. In Mus. Hopeiano Oxonise (olim Saunders). 



Tbis species so closely resembles C. truxilla in general form and appearance tbat it 

 might easily be considered to be a variety of that species ; but the arrangement of the 

 veins proves them to be totally different, there being a very distinct elongate-ovate cell 

 in C. ecuadoria, formed at the base of the branches of the postcostal vein, the 2nd, 3rd, 

 4th, 5th, and 5*th being emitted at nearly equal distances apart at the extremity of the 

 ceU (Plate XXVIII. fig. 10). 



61. (6) Castnia zagkr^a. " Ailes superieures noires avecune bande longitudinale fauve, 

 sinuee, un peu irreguliere, coupee par les nervures partant du milieu de la base et 

 se prolongeant vers le bord posterieur ; outre cela, il y a sur le milieu de la c6te un 

 petit trait, et au-dessous de celui-ci une tache iin peu triangulaire de la meme 

 couleur, divisee par les nervures, l'extremite posterieure offre deux rangees paralleles 

 de taches blanches lavees de jaune ; mais la premiere rangee ne descend pas au-dela 

 du milieu de l'aile." Expans. alar, antic, unc. 4|.

Sab. Panama. In Mus. Eelder. 



This is the Heterocerous coiinterpart of Papilio zagrceus, which is itself the counterpart 

 of one of the Heliconian butterflies. 



Nearly allied to C. cratina, Westw., but with the fulvous markings of the fore wings 

 and the black markings of the hind wings much less developed in size. Eore wings 

 black, with a longitudinal fulvous vitta of irregular width, extending from the base of 

 the wing along its middle, rather defiexed and narrowed at its extremity ; considerably 

 beyond the middle of the wing an oblique cuneated patch of the same colour arises at 

 the middle of the costa, followed by a row of six suboval spots, the lowest of which ranges 

 with the extremity of the central bar ; beyond these is a submarginal row of nine white
