CECKOPTEKUS.— EHABDOIDES. 331 



ences, that we can detect, are the rather more compact transverse band of the primaries 

 and the absence of any green tint to the head and thorax. When we compare the sexual 

 organs of the male profound differences are revealed. The lower portion of the harpes 

 in the present species is very much produced and bent upwards nearly to a semicircle ; 

 the upper portion is also produced, but is straight, terminating in a blunt end. (See 

 Tab. LXXX. fig. 7.) 



Our type specimen is from Panama, and is the one dissected ; our other specimens 

 are placed with it on the faith of external characters, but we are doubtful if anything 

 short of actual dissection can prove their position. 



EHABDOIDES. 



Rhabdoides, Scudder, Butt. E. U. S. iii. p. 1854 (1889) ; Wats. P. Z. S. 1893, p. 34. 



Mr. Scudder separated this genus for Eudamus cellus of Boisduval and Leconte, a 

 well-known North-American species, which ranges throughout the uplands of Mexico. 

 With it we associate Myscelus epigona of Herrich-Schaffer, as the male of that species 

 is destitute of a costal fold to the primaries ; it agrees, too, in neuration, but the male 

 genitalia are like those of Achalarus lycidas. 



Compared with Achalarus the discocellulars of the primaries are rather less oblique 

 to the axis of the wing, and the recurrent nervule starts from a point a little beyond 

 the middle of the third median segment instead of at the end of it. The primaries of 

 the male have no costal fold as in Achalarus. The secondaries, though slightly 

 produced at the anal angle, have no tail or distinct projection, nor have they any trace 

 of a radial, nor of a tuft of hair on the upperside of those wings, or from the proximal 

 end of the hind tibiae ; the second median branch starts before the end of the cell.
