GENUS CASTNIA AND SOME ALLIED GROUPS. 189 



nigricante lateribus segmentisqiie 5 apicalibus subtus fulvis ; tborace subtus albido 

 Tario ; antennis albidis. Long. eorp. unc. 1|-. Expans. alar. antic. unc. 4<\. 

 Sab. Amazonia. In Mus. Hopeiano Osonise (olim Scmnders). 



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

 arrangement of the cell and branches of the postcostal vein agrees with that of 

 C. cycna, 



60. (5) Castnia ecuadoria. (Plate XXXII. fig. 6.) Alis anticis oblongo-ovatis apice 

 rotuudatis ; e basi ultra medium obscure lutesceutibus, 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 anaU versus medium alte extensa fimbriaque fuscis ; corpore fusco ; coUari, 

 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. Ij. Expans. alar. antic. unc. 3f. 



Hab. Ecuador. In Mus. Hopeiano Oxonias (oUm /S^awit^ijrs). 



This species so closely resembles C. trimlla in general form and appearance that it 

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

 veins proves them to be totaUy difi^erent, there being a very distinct elongate-ovate ceU 

 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 nearlyequal distances apart at the extremity of the 

 ceU (Plate XXYIII. fig. 10). 



61. (6) Castnia zagk^a. " Ailes superieures noires avec une bande longitudinale fauve, 

 sinuee, un peu irreguUere, coupee par les nervures partant du miUeu de la base et 

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

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

 couleur, divisee par les nervures, rextremite posterieure oflfre deux rangees paraUeles 

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

 du miUeu de Taile." Expans. alar. antic. unc. 4j.

Sab. Panama. In Mus. Eelder. 



This is the Heterocerous counterpart of Papilio zagrmis, which is itself the counterpart 

 of one of the HeUconian butterflies. 



Nearly aUied 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 

 therwing along its middle, rather deflexed and narrowed at its extremity ; considerably 

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

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

 withthe extremity ofthe central bar ; beyond these is a submargiual row of jiine white
