submedial shade extends outwardly to the margin. A black dot marks 

 the reniform at median vein; an extra-mesial row of dots on the ner- 

 vules, not prominent. The veins are indistinctly paler. The darkest 

 portion of the wing is along the median vein, and a fine black streak 

 runs along the interspace between veins 4 and 5. Hind wings whitish, 

 vaguely soiled with fuscous exteriorly. Thorax concolorous with 

 primaries; no lines on the collar. Beneath without marks. This 

 species recalls in maculation lajndarla, but is more diffusely shaded, 

 the spots of the outer line more numerc^us, the hind wings darker, the 

 body more slender. 



Eoc2Mnse.—l.^'2 inches (33 mm.). 



Ilahltat.— hong Island, near the seashore, in May. 



The species was taken l^y Mr. Fred. Tepper who had a cotype, and 

 this is the only example of Jfahilis known to me in any American col- 

 lection. It is probable that the insect is very local and that may 

 account for its absence in cabinets. I have already stated that I can 

 see no difference between ligata avAflahills except that the latter lacks 

 the purplish shading. But the Tepper specimen has a purplish tinge, 

 and I have a Texas example that has as little. An expanse of 33 mm. 

 is too great for the cotype and too great for any Ugata known to me. 



Theliiescription is essentially that originally given by Mr. Grote. 



LEUCANIA RIMOSA Grote.

Fore wings hoary gray, something like .7/r/r/?'« in color; irrorate with 

 dark speckfes and with a faint warm shade, reminding one a little of 

 un'qninda in these respects. Allied to commoldes; no lines or spots 

 visible except that there is continuous series of excessively minute sub- 

 terminal dots, and the median vein is faintly marked with white and 

 edged with black; the white color accentuated at base of third and 

 fourth median nervules. Hind wings pale gray, whitish, veins soiled. 

 Beneath a blackish shade marks the inception of the subterminal Ime 

 on costa, and the median vein is shaded at base of nervules. Hind 

 wings with costa darker; no lines or spots. Face and pectus a little 

 smoky; fore tibiw pale outwardly. Thorax gray; abdomen paler. 

 E:qxin!<e.—1.M inches (34 mm.). 

 lIah!tat.—K\itQvy Point, Maine. 



No one has taken this species save Dr. Thaxter, so far as I am aware, 

 and the original type is with him. A second specimen which he kindly 

 sent me is smaller-only 31 mm.— and the longitudinal shading through 

 the center of the wing is quite obvious though not conspicuous. I 

 can not find anything to suggest eommoides.
