This species was found near Los Angeles, by Mr. Lorquin, who gave me several specimens. In the male the black color is more predominating, in the female the fulvous coloration.
For the sake of completing this series of diagnoses, I give here the description of a third species, that I received, by the kindness of Dr. Dinklage, from the Sierra Madre, in the neighborhood of Mazatlan. I think it indispensable to give the marks of this closely allied Nemeobius, as I am of the opinion that thus errors will most effectually be avoided.
N. Mejicanus, Behr.
Alæ supra fulvæ, marginem versus brunneæ, fasciis maculisque ordinariis omnibus albis nigro marginatis instructæ. Subtus alæ anteriores fulvæ, apice et margine grisescentes, fasciis et maculis ut supra. Alæ posteriores grisescentes, macalis albis et nigro marginatis et confluentibus cum colore universali irregulariter variegatæ.
The most positive and striking points of difference would be thus:
1. N. Dumeti. Fore wings alone show a fulvous coloration on the upperside. Bands and spots perfectly white.
2. N. Mejicanus. All wings are occupied with it, till beyond the second band, where the brownish coloration of the margin begins. Bands and spots perfectly white.
3. N. Virgulti. Extension of the fulvous as in the preceding, but all the space more or less occupied by black. Middle band nearly altogether fulvous, other bands and spots white.
As much as we know, the type of this genus N. Lucina L, was the only species known heretofore, and it is another proof of the various repetition of types on occidental coasts, that we have to add three Pacific representatives of a genus first discerned in a single European species.
