NYMPHALID.E. 171 



near anal angle, parallel to hind-margin, a row of a few, 

 shining-blue dots; on hind-margin, above first median nervule, 

 one or two dull-red lunules ; from first median to anal angle, 

 some greenish-ochreous lunules ; a rather slender tail at 

 extremity of both first and third median nervules. UNDER- 

 SIDE. Dull brownish-olivaceous, with blue-black, occasionally 

 white-edged, transverse striae ; an irregular streak from costa 

 of fore-wing near apex, to near anal angle of hind-wing, 

 running near, and almost parallel to, hind-margins. Fore-wing : 

 two dusky -blackish spots near anal angle. Hind-wing : red 

 and olivaceous lunules much more distinct than on upper-side ; 

 the transverse streak crossing both wings is in this wing 

 immediately succeeded by a row of dull -red lunular markings. 



? . Brownish-black, glossed with violet-blue : transversely 

 striped and spotted with white. Fore-wing : on costa, a little 

 beyond middle, commences a transverse row of white spots, 

 interrupted on second discoidal nervule, and from first median 

 nervule widening into a gradually-broader band of contiguous 

 white spots, violet-margined on each side, to inner-margin a 

 little beyond middle; on costa, near apex, commences a second 

 row of smaller white spots, tinged with ochreous or bluish, 

 extending to about middle of inner row of spots, where it 

 becomes almost obliterated. Hind-wing : white, violet- 

 margined band of fore-wing continued more broadly across 

 middle of this wing to just before anal angle ; a row of seven 

 more or less distinct, white lunules, parallel to hind-margin ; 

 on hind-marginal edge, the olivaceous and red lunules are 

 larger and distincter than in $ , those of the latter colour 

 extending to apex. UNDER-SIDE. Similar to that of $ , but 

 paler and more glistening ; with transverse white band in 

 fore-wing. Fore-wing : white band less distinct than on 

 upper-side ; blackish spots near anal angle larger than in $ . 

 Hind-wing : a very indistinct, irregular, olivaceous-whitish 

 median band, outwardly edged with a blackish streak ; the 

 dull-reddish, lunular markings, immediately succeeding band, 

 larger and more contiguous than in $ ; hind-marginal lunules 

 as in $ , but more conspicuous. 



Whether Boisduval intended to call this species Erithalion 

 I know not, but 1 have given the name as printed at the head 

 of his description in the Appendix to M. Delegorgue's Travels. 

 The figure in the " Genera of Diurnal Lepidoptera " which 

 is named Nymphalis Erithalion was published three years 

 subsequently to Boisduval's description ; but was so named, 

 I believe, from a manuscript label of the French author just 

 mentioned, attached to a specimen of the Butterfly in the 

 British Museum.
