1866.] MR. P. L. SCLATER ON THE GENUS NEOMORPHUS. 59 



Note. — Dr. Herrich-SchJifFer, in his ' Lepidopterorum Index Sy- 

 stematicus,' gives names to four species in this genus (D. schenckii, 

 arema, hermippe, and nerippe). Dr. Boisduval has also named 

 several species, some of which (D. nerippe, azema, lixa, and daulis) 

 have been immortalized in Mr. Doubleday's 'Genera.' I am not, 

 however, able to make use of these names, as I have not seen the 

 insects for which they are intended.

(Plate V.) 



In a note upon the Cuckoos of the genus Neomorphus, published 

 in the Society's ' Proceedings ' for 1864, I pointed out the characters 

 which separated the two species of this peculiar genus then known 

 to me, and gave some information as to their geographical distribu- 

 tion. In the series of birds lately received by Mr. Osbert Salvia 

 from Veragua, a specimen of what appears to me to be a third species 

 of the genus occurs. Knowing the interest I take in this group, 

 Mr. Salvin has kindly handed the bird over to me for comparison ; 

 and I propose to call it, after my friend who has devoted so much 

 time and toil to the Natural History of Central America, Neomor- 

 phus salvini. 



Curiously enough this new northern species of Neomorphus is 

 much more nearly allied to the Brazilian N. geoffroyi than to N. 

 rufipennis of Guiana and Amazonia. It is, however, in my opinion, 

 quite sufficiently distinct to merit specific separation, and will, I 

 think, be readily recognized by the characters given in the following 

 synopsis of the species of the genus which have come under my ob- 

 servation : —
