PAEADEOS.— DEEPHALTS. 349 



In the catalogue of the Hewitson collection E. oriander is sunk as a synonym of 

 E. formosus, but the two insects seem fairly separable by the characters given above. 

 The difference between them is not sexual, as we have before us males and females of 

 both forms. 



P. oriander is included in this work on the evidence of a specimen in the British 

 Museum said to have come from Honduras. The type was obtained by Bates during 

 his journey to the Amazons, and we have one of his specimens from Para, where 

 Mr. Herbert Smith also found it. Others in our collection are from Maranham. 



DREPHALYS. 

 Drephalys, Watson, P. 7, S. 1893, p. 34. 



Closely allied to Paradros, but may be distinguished by the rather shorter terminal 

 joint to the palpi, the more abruptly curved antennae, and by the greater production of 

 the secondaries. A distinct costal fold to the primaries in the male. 



Mr. Watson established this genus for Eudamus helixus, Hew., and compared its 

 characters with those of Typhedanus. There can be no doubt that Drephalys should 

 be placed next Paradros, and the only question that arises is whether these two genera 

 ought not to be merged into one. On the whole we think it best to keep them separate 

 on the grounds stated above. 



1. Drephalys helixus. (Tab. LXXXI. figg. 22, 23, 24 e .) 



Eudamus helixus, Hew. Ann. & Mag. N. H. 1877, xx. p. 320 \ 

 Drephalys helixus, Wats. P. Z. S. 1893, p. 34 2 . 



Alis saturate fuscis ; anticis ad basin viridi-fulvo radiatis, area? costalis dimidio basali fulvo, macula ad medium 

 marginis interni albida, maculis duabus semihyalinis, una cellulari, altera infra earn et duabus ultra eas, 

 punctis duobus subapicalibus quoque semibyalinis ; posticis fasciis duabus transversis maculosis fulvis, una 

 per eellulam, altera discali : subtus rufescenti-fuscis ; anticis medialiter nigricantibus, maculis sicut in pagina 

 superiore ea ad medium marginis interni majore et albicantiore ; posticis lilacino suffusis, area costali 

 glauco atomata, fascia mediana lata arcuata alba, nee costam neque marginem internum attingente, et 

 margine iriterno ipso pro dimidio distali albis : antennis nigris ; palpis albidis, segmento terminali nigro ; 

 corpore subtus et pedibus ocbraceis. 



Hab. Panama, Calobre {Arce), Lion Hill (M'Leannan). 



Hewitson described this species from a specimen from an unknown source. The 

 only other examples we have seen were all sent us either by Arce or M'Leannan from 

 the State of Panama. 



There is no difference between the sexes, except that the male possesses a costal fold 

 to the primaries. 



The male genitalia have a cleft tegumen; the scapbium is well developed; the 

 harpes are truncate, and from the middle of the terminal edge a short lobe arises.
