EUDAMUS. 285 



Dr. Staudinger has kindly lent us his type of Eudamus calenus, Mabille, and we find 

 that it agrees accurately with our series of E. octomaculatus. 



The male genitalia have a rather long tegumen cleft at the end, but without lateral 

 lobes ; the scaphium is well developed and turned downwards ; on the harpagones 

 there is a concave depression towards the end of the dorsal edge, finely serrate and 

 ending in a blunt point directed slightly upwards. (See Tab. LXXV. fig. 23.) 



11. E. alcipheon section. A large white patch on the middle of the secondaries 



beneath. 



24. Eudamus alciphron, sp. n. (Tab. LXXV. figg. 24, 25.) 



E. octomaculatce similis, sed posticarum cauda longiore et subtus plaga magna discali extrorsum late fusco 

 marginata alba distinguenda. 



Hab. Mexico, Eincon in Guerrero (H. H. Smith), Coatepec in Vera Cruz (Schaus). 



We have but a single specimen of this species, apparently a female, which differs 

 obviously from E. octomaculata, the large white spot on the secondaries beneath 

 rendering it very distinct. A second in the collection of Mr. Schaus precisely 

 resembles the type. 



B. A pencil of hair at the base of the submedian nervure of the primaries of the male 

 beneath, the costa of the secondaries being strongly arched at the base ; or a pencil 

 of hair between the median and submedian nervures of the secondaries above near 

 the base. (Polythrix, Wats.) 



d. A pencil of hair at the base of the submedian nervure of the primaries of the male 



beneath. (Polythrix.) 



25. Eudamus metallescens. (Tab. lxxv. figg. 27, 28, 29 6 .) 



Eudamus metallescens, Mab. Le Nat. x. p. 108, f. 2 (1888) \ 



Alia murinis ad basin viridi lavatis ; anticis maculis quatuor medianis, una subquadrata in cellula, una utrinque 

 rami mediani secundi et una obsoleta infra eas ochracea hyalinis punctis quatuor costalibus ad apicem : 

 subtus anticis maculis ut supra, area interna albida, area supra venam submedianam cirrosa, costse basi et 

 posticis plerumque aureo-viridibus ; posticis linea margini externo subparallela flavo-albida ; capite et 

 corpore plerumque cum palpis viridibus ; plica costali obvia. 



Hab. Panama, Chiriqui (Trbtsch, in mus. Staudinger), San Miguel, Pearl Islands 

 (Champion). — Amazons Valley 1 . 



Our specimen agrees with one lent us by Dr. Staudinger, which has been named by 

 Mons. Mabille, doubtless from the type which came from Maues in the Amazons 

 Valley 1 . Our example, however, is small, and when perfect would have possessed 

 longer tails ; these unfortunately are now broken. It possesses the peculiar tuft of 

 hairs which is attached to the underside of the primaries between the median and
