A. R. Grote's Notes on the Zygrenidae of Cuba. 307 



Melanchroia cephise, Hiibner, u Sammlung," (not " Verzeichniss") 

 seems to me to represent the smoky black M. fumosa. and not the blue- 

 black Phalsena chephise, Cramer, contrary to the intention of the Ger- 

 man Entomologist, who intended to illustrate Cramer's species. 



Melanchroia geometroides. 



Melanchroia geometroides, Walker. C. B. M. Lep. Het. Part 2, p. 387. (1854). 

 Glaucopis mors, Lucas, Hist. Nat. Cub. p. 663. (1857). 



Mr. Walker gives "Java," as the habitat of this species in the Bri- 

 tish Museum Lists. The diagnosis there given agreeing exactly with 

 my specimens, I was led to doubt the correctness of this locality, the 

 more so as I regarded the genus as purely American in its character. 

 Upon communicating by letter with Mr. Walker on the subject, I have 

 been kindly informed that there is every probability that the British 

 Museum specimens came from Jamaica, and that a mistake has arisen 

 from the similarity of the customary abbreviations for these two locali- 

 ties. I have examined several specimens ( % and $ ) of this slightly 

 variable but very simply marked species, which I have no doubt, from 

 the diagnosis, has been redescribed by Lucas as above cited.

DIOPTIS, Hiibner. 



Dioptis vinosa. 



Sphinx vinosa, Drury, Exot. Vol. I, p. 47, PI. 23, fig. 4, et Vol. II, App. (1770). 

 Callimorpha / vinosa, Westwood, Drury, Vol. I, p. 43, PI. 23, fig. 4. (1837). 

 Dioptis vinosa, Walker, C. B. M. Lep. Het. Part 2, p. 332. (1854). 

 Hyalurcja vinosa, Herrich-Sehaefier, Cor. B. M. Peg. No. 9, p. 131. (Septem- 

 ber, 1866). 



I adopt Mr. Walker's generic determination for this species, since 

 this is apparently congeneric with D. cyma, Illlb. the type of Dioptis 

 in the "Verzeichniss." Other species and groups referred here by Mr. 

 Walker, seem to need revision. D. vinosa, is variable as to color and 

 size; sometimes the sub-terminal, oblique, ferruginous or honey-yellow 

 band, of the upper surface, is entirely obsolete. Its variability suggests, 

 that Dioptis rica, Hubner, has been improperly considered as distinct 

 from the present, the oldest illustration of the genus.
