 BY AUGUST BUSCK. 



Amorbia emigratella,new species. Male and female. 



Female. Basal joint of labial palpi short, ochreous; second joint 

 long, porrected, rust-red, with a violaceous sheen on the tip ; terminal 

 joint short, reddish brown, shaded with black. Face behind the palpi 

 short-scaled, whitish; head reddish brown, mixed with ochreous and 

 uith a short pointed frontal tuft. Antennae reddish brown, simple. 

 Thorax and patagia uniformly dark brown. Fore wings with base 

 .of costa strongly arched; costal and dorsal edges nearly parallel; 

 apex squarely pointed; termen slightly sinuate below apex, thence evenly 

 rounded; ochreous brown, shading into light ochreous on the terminal 

 third: the edge between two colors is not sharply drawr. but the 

 limits are still quite distinct, the lighter color occupying the an a 

 below a straight line from basal fourth of the dorsal edge to apex. 

 From just before the middle of costa runs an indistinct, dark bluish- 

 gray band obliquely outward towards tornus, but fades out in the 

 ochreous part of the wing and is even interrupted in the brown costal 

 part : parallel with this is another similarly colored, but less distinct . 

 streak at apical third, also disappearing in the light portion of tin- 

 wing. On the dorsal edge at basal fourth and at the middle are 

 two short dark gray streaks, parallel with the costal streaks. The entire 

 wing is finely mottled with a close transverse apparently darker 

 striation, which is produced by transverse rows of slightly elevated 

 scales. These markings are of varying intensity in different specimens. 

 some showing hardly any trace of the darker cross-bands and having 

 the ground-color lighter and nearly unmottled except for the tine 

 transverse striation caused by the slightly raised rows of scales. 

 Hindwings light straw-yellow, with the apex mottled with dark hnmn 

 and black and with the costal cilia absent and abruptly beginning 

 again just before the tip of the wing. Cilia straw-white. Underside 

 of the forewings reddish ochreous, with a blackish terminal line 

 before the cilia. Abdomen light yellow. Legs straw-yellow : tin- 

 anterior and middle legs shaded with reddish brown exteriorly and 

 with the tarsi faintly annulated.

Male. Of considerably smaller size and of a general lighter color 

 Forewings nearly uniformly light ochreous without the darker ba-.,l 

 and costal shade. The first costal dark streak is represented by a
