Description of Papilio Electryon. 

 By O. W. BARRETT, Tacubaya, Mexico. 

 Being unable to find a recorded description of the female of 

 P. electryon G. &S., I herewith submit the following : 



P. electryon G. & S. 9- Wings more dusky and primaries less pro- 

 duced at apex than in ^; primaries above with apical band composed of 

 eight isolated yellowish spots, bent near middle of outer margin at an angle 

 of no degrees, and continued to posterior angle; sub-parallel to apical 

 row is a discal row of seven obscure olivaceous patches ; no trace of 

 common yellow band of ^ : secondaries with submarginal row of seven 

 flat, thick, rufous lunules, the two nearest apical angle reduced to yel- 

 lowish patches and the one at anal angle a round spot ; the discal row of 

 six glaucous patches of same position as in (J but more distinct ; inside the 

 glaucous row and well beyond the end of the cell a band of seven rufous 

 lunules extends from the costa to inner margin, the lunules being ap- 

 pressed, or U-shaped, and separated by the black veins, those near 

 anal angle being thickened, whereas the one at the costa is a curved dash 

 suffused with buff scales. Primaries beneath with two rows of spots as 

 above ; the apex paler ; the luteous dash on the costa as in <$ ; and the 

 extremities of the broad yellow band of tf represented by an obscure 

 olivaceous cloud in the cell near the costa, and another on the inner mar- 

 gin near posterior angle : secondaries fuscous beneath ; lunules as above, 

 except that those of the inner band are of a nearly even thickness 

 throughout ; the glaucous patches are rfcplaced by olivaceous clouds 

 edged with pale blue on the inner side and separated from the rufous 

 lunules by deep black lunulate patches. Fringe between veins whitish. 

 Caudate appendages wider than in <$. Expanse no mm. 



Described from one female specimen from Orizaba, V. C., 

 Mexico. 



Readily distinguished from melanic 9 of P. asdepius Hbn. 

 by the presence of the row of olivaceous patches on primaries 

 and by the apical row of spots reaching posterior angle, being 

 bent at lesser angle, and containing three isolated spots (not 

 four broad dashes) in its first portion ; also by the shape, 

 color and position of lunules on secondaries. 



Have never seen a specimen of P. asdcpuis Hbn. from the 

 Eastern Slope of Mexico, nor a specimen of P. electryon 

 G. & S. from the Central or Western regions. Doubt has 

 been expressed as to the non-identity of these species, but the 

 as well as 9 9 show differences as striking as those of 

 P. pilummis Bdv. and P. delimits Bdv.
