A new Variety of Megathymus yuccae (Lepid.)* 



By HENRY SKINNER, M.D., Philadelphia, Pa. 

 Megathymus navajo n. var. 



The specimens appear to be all males. They are black in 

 color, while all the specimens of yuccae 1 have seen are chest- 

 nut brown. They range in size 40, 45, 47 and 50 mm. in ex- 

 panse respectively. The specimens of yuccae in our collection 

 range in size from 62 to 68 mm. This variety is similar to 

 coloradensis Riley, but is quite different in color. The speci- 

 mens were sent to me by Mr. W. C. Wood of New York, 

 along with a lot of specimens of Megathymus streckeri Skin- 

 ner, and at first I took the four small, black specimens of 

 navajo to be males of streckeri as they are the same color 

 (black). They came from Fort Wingate, New Mexico and 

 were taken May I3th, 25th, 3ist and June I3th. One speci- 

 men's label says "on mountain back of Fort." 



The name navajo was suggested by Mr. Wood. The but- 

 terfly comes from the home of these Indians. 



The specimens of streckeri were taken on various dates 

 through the month of June and make a new record for the 

 species. 



Yuccae and its two varieties may be distinguished from the 

 other species of the genus by the distinct triangular white spot 

 below the centre of the costa on the under-side of the secon- 

 dary wings. 







A new Datana (LepicL). 



By JACOB DOLL, Brooklyn, N. Y. 



Datana neomexicana n. sp. 



Very near Datana integerrima var. cochise Dyar in coloration but 

 differs in having the fore wings of almost uniform pale gray color, 

 sprinkled more distinctly with small, dark punctures ; the costal 

 shade rather feebly contrasted and of pale ochreous color; distal 

 spot obsolete ; the lines as usual ; the oblique dash near apex obso- 

 lete; the form of fore wings as in Datana calif arnica Dyar. 



Habitat New Mexico. 



Type One pair in the collection of the Museum of the 

 Brooklyn Institute; cotype, one pair in my collection. 



This species is very distinct from D. integerrima var. cochise 

 Dyar, which it resembles at first sight more than any other 

 Datana, by the characters given above which are constant in 

 the specimens I have seen through the kindness of Messrs. 

 Brehme and Erb.
