Wings above, in the male, deep emerald -green, with a rich golden refulgence, spreading over the 

 surface to a deep black border, which is narrow and regularly defined in the^re wings, broader 

 and indented in the hinder wings ; in the female black, the greenish golden lustre being limited, 

 in the fore-wings to a medial patch extending to the base, and in the hinder to a triangular 

 spot occupying the basal areolet: underneath brown, in some individuals inclining to gray ; for^ 

 wings, with a series of three successively larger dark brown spots in the medial area surrounded 

 with pearly shining rings, the first near the base being smallest, the exterior one on the disk 

 constituting a short broad band bordered with white undulated marginal lines ; the contiguous 

 portion of the anal area marked with two oblong tapering obliquely diverging spots of the 

 same colour ; behind the disk follows a broad dark-brown complete fascia, broken in the 

 middle, with white undulated edges, and finally, parallel with the margin, a more obscure band 

 with paler grayish undulations ; hinder tvings with six or seven oval or irregularly round dark 

 brown spots, narrowly edged with gray, disposed in two successive interrupted rows near the 

 base ; next, a more prominent transverse band, of the same colour, simple and broad in the costal 

 area, subdivided into two parallel branches, in the medial and anal area ; behind this an obsolete 

 band parallel with the margin, faintly undulated with gray, and succeeded in the anal region by 

 three deep black oblong lunular spots, arranged in regular succession close to the margin, the 

 interior one being somewhat larger and marked with an intensely black subocellate spot, the 

 whole being confined along the inner edge by a waving emerald green band richly covered with 

 irrorations of a golden lustre. The body above agrees in colour with the adjoining portion of 

 the wings, and underneath is covered with a light gray down. The antennts are brown to the 

 middle and ferruginous towards the extremity. The intermediate tail is slender, tipt with gray, 

 and the lateral tails are very minute. 



Cramer gives a distinct figure of the male of this species. Our collection contains one male and two 

 female specimens ; by these materials I have been enabled to point out clearly the difference between 

 Eumolphus and Helus, and to remove the doubt, expressed by the authors of the Encyclopedie, regarding 

 their distinctness as species.
