Mr. Walker has referred Perigonia stulta Boisd., H-S. Exot. fig. 

 106, as a synonym of this species, but I believe it is distinct. The 

 following are some of the differences : — The size of P. stulta is smaller ; 

 the shape of the external margin of the anterior wings is modified from 

 that in P. lusca, being more produced medially and at internal angle. 

 The shading and coloration of the terminal space is different. In P. 

 lusca, a well defined blackish line runs from apex to internal angle, 

 which is entirely wanting in Dr. Herrich-Schfeffer's figure. Finally, 

 the yellow of the posterior wings is more intense, and absorbs the en- 

 tire base of the wing in P. stulta. Like the species of Etii/o, the species 

 of Perigonia are nearly allied and easily to be confounded, which how- 

 ever does not lessen their specific validity. Two specimens. S and 9 • 

 Exp. S 2.10, 9 2.30 inch. Length of body S and $ , 1.20 inch.

Smaller than the preceding which it resembles, but differs as fol- 

 lows : — The median line on anterior wings is not followed by a dark 

 diffuse shade as in P. lusca, and the markings generally not so strong ; 

 the external margin is more angulated and less rounded ; the yellow of 

 the posterior wings is more intense and like that in P. stulta; there is 

 no yellowish patch at anal angle as in P. lusca. The female specimen 

 sent is much darker than the male, which it otherwise resembles. Two 

 specimens, % and 9 . Exp. % , 1.80 inch. 9 1.90. Length of body

I have not had access to M. Ramon de la Sagra's work in which 



Lucas' description is contained, but have used instead Dr. Herrich- 



SchiBffer's very acceptable resume of its lepidopterological contents, 



given in the pages of the " Correspondenz Blatt." Dr. Gundlach seems 



to have sent a specimen of P. lusca under the present name to Dr. 



Herrich-Schseffer ; I do not doubt the specific validity of my specimens, 



or the correctness of their identification with Macroglossa Lefebvrii 



Lucas.
