 septem aureis, una ad cellulse finem, sex in serie transversa ultra earn, margine interno ferrugineo ; 

 # oculorum ambitu rufo ; abdomine subtus flavo ; ciliis posticarum alterne fuscis et albis. 

 $ ignota. 



Hab. Costa Eica, Irazu (Rogers l ). 



This fine species was described by Salvin and myself twenty years ago from a single 

 male example from Costa Rica, and it still remains unique. We know nothing closely 

 allied to T. aurifer, and place the insect in Thracides with some reserve. The primaries 

 have a steely lustre on their distal half, a character we omitted to note in the original 

 description, this peculiarity being also shown in the two species of the genus Cceliades, 

 to which, however, the present insect is not very nearly allied. 



d'. Primaries not branded in the male *. 

 c". Primaries with hyaline or flavo-hyaline spots, the secondaries immaculate above. 



9. Thracides polles, sp. n. (Tab. cv. figg. 29, 30, $ .) 



$ . Alis fuscis, maculis tribus in linea obliqua, una ad venam submedianam, secunda inter ramos medianos 

 pnmum et secundum maxima et externe valde angulata, tertia ultra earn, una elongata in cellula, 

 punctisque duobus aut tribus in linea obliqua subapicalibus, flavo-hyalinis : subtus anticis ut supra, sed 

 palhdionbus, area mediana obscuriore, angulum analem versus litura magna flavescente ; posticis (margine 

 costali excepto) griseis, maculis tribus indistinctis discalibus albidis ; capite et corpore subtus griseis. 



Hab. Nicakagua, Chontales (Belt); Panama, Chiriqui (coll. Staudinger), Bugaba 

 (Champion). — Brazil. 



We have seen five specimens of this species, all females, three being from within 

 our limits. It is easily separable from most of its allies by the grey underside of the 

 secondaries. In one of Dr. Staudinger's Brazilian examples the spots on the primaries 

 are'much reduced in size, those near the apex and the one in the cell being absent. 

 In the absence of the male, we refer this insect to Thracides with some hesitation.

Hab. Panama, Volcan de Chiriqui (Champion), Chiriqui 2 . — Colombia K 



Dr. Butler's type of this species, a male, is in our collection, and we have a female 

 of it from Chiriqui, whence Mabille's specimen of Proteides laurens was obtained. 



* The male of T. polles is unknown.
