_ Allied to subjecta Wik. but the maculation is paler and the whole 
area between subcostal fold and inner margin is filled with the white 
band. 
PYGARCTIA FLAVIDORSALIs sp. nov. (Pl. IV, Fig. 3). 
Antennae black; palpi gray-brown, yellow basally; legs gray, coxae of 
fore legs yellow, hind femora and tibia paling into whitish; front and head and 
abdomen dorsally yellow, latter with dorsal row of black spots; thorax, patagia 
and wings white, immaculate. Beneath, abdomen and wings white. Expanse

Hasitrat. San Benito, Texas (Mch. 16-23) (July 16-23) (Aug. 1-7) (G. 
Dorner) 44, 32. Types, Coll. Barnes. 
The species is close to elegans Stretch., differs from it in the ab- 
domen and front being distinctly yellow and not rosy. As this feature 
is constant in all the specimens before us we conclude that if not a 
good species it is at least a distinct race and worthy of a name. 
PYGARCTIA MURINA ALBISTRIGATA subsp. nov. (Pl. III, Figs. 10, 12). 
Head, thorax and primaries mouse-gray, the latter with a distinct whitish 
spot or mark on the discocellulars and usually with the veins beyond the cell 
streaked with the same color. Secondaries in the ¢ whitish with broad smoky 
border, in 2 entirely smoky. Abdomen, collar, and edges of patagia scarlet. 
Expanse @ 25 mm., ? 28 mm. 
Hasirat. San Benito, Texas (May-June) (G. Dorner) 6¢’s, 39’s. Types, 
Coll. Barnes. 
Differs from the type form from Arizona in the pale striations of 
primaries. Hampson places murina in the genus Euchaetes but a long 
series of specimens in Coll. Barnes all show the claw on front tibia 
characteristic of Pygarctia. Our Texan race also possesses the claw.
