twcea them to make it worth while to institute the comparison, the 

 figure reminding one equally of any species of the genus, or indeed any 

 " Sphinx " with yellowish secondaries. It would be an act of injustice 

 to naturalists, were species referred as intended by earlier authors on 

 grounds, even much more tenable, than those which authorize me to de- 

 scribe the present as a new species. Prof. Poey writes, respecting an 

 unpublished MSS. name for this species : •' H-S. I'a recu de Paris sous 

 le nom de Mnechus."

The specimens accord sufficiently well with the citations, as to pre- 

 vent any donbts of the correctness of the determination. The anterior 

 wings, in my specimens, are generally paler than in the original figures; 

 this is noticeable particularly in the male, in which a paler shade ex- 

 tends along the lower half of the wing, from before the middle of inter- 

 nal margin, obliquely to external margin, latter denticulated ; in the 

 female the wing is darker, more unicolorously blackish-brown.

Erinnyis Merianae, nov. sp. (Plate 2, fig. 2. J .) 



Anterior wings, deep blackish-brown, all the transverse lines subob- 

 solete. A sub-triangular, subcosto-apical, cinereous patch; a distinctly 

 defined cinereous patch at about the middle of internal margin, beyond 

 which the region within the internal angle is shaded with dull cinere- 

 ous scales, which show as pale margins to the subobsolete, transverse, 

 subterminal, undulating blackish lines; external margin denticulate; 

 nervules, interrupted narrowly with cinereous; at base of wing, a few 

 cinereous hairs. 



Posterior wings, dull reddish ferruginous, with a narrow, blackish, 

 shaded border; dull cinereous at anal angle, where a black line is appa- 

 rent; fringes, from anal angle along internal margin, whitish. 



Under surface, dull brownish ; base of both wings whitish, especially 

 posterior pair; disc of anterior pair very distinctly covered with reddish 

 ferruginous, hairy scales; costa at base, and towards the centre on pos-
