Morrison,] 146 [November 4, 



are widely geminate, blackish, confused and irregular, as is usual in 

 this genus. The interior line is strongly marked on the. costa, oblique, 

 and forming a dent beneath the submedian. Orbicular spot reduced 

 to a round, clearly defined dot, and the claviform to a similar 

 dot on the interior line. Reniform spot of ordinary size, shaded 

 with ferruginous, subquadrate, and containing at each corner a clear, 

 white, punctiform dot, the one at the lower outermost corner gemi- 

 nate. The median shade extends from the costa obliquely to the base 

 of the reniform spot, then perpendicularly to the inner margin. 

 Component lines of the geminate exterior line separated by a wide 

 concolorous space; they are both acutely dentate, drawn in beneath 

 the reniform spot, and produced on the submedian nervure in a 

 sharp tooth. The inner line is the most distinct. Subterminal 

 line faint, preceded by irregular, well-defined ferruginous shades, 

 most evident in the centre of the wings. A series of black dots at 

 the base of the concolorous fringe. The posterior wings are. semi- 

 translucent, with discal dot and dark tinted nervules. Anterior 

 wings beneath dark gray. A black spot on the costa marks the point 

 of inception of the exterior line. Posterior wings as above, the dot 

 slightly more distinct and also darker terminal shadings.

 tion of my friend Mr. F. C. Bowditch, of the Harvard Law School. 



Distinguished from the three known species of the genus, as well as 

 from M. Guenee's unidentified ones, by the clear gray anterior wings 

 and thorax, and the peculiar disposition of the white spots in the reni- 

 form spot. 



Segetia fabrefacta nov. sp. 



Expanse 30-32 mm. Length of body 15-16 mm. 



Eyes naked, without lashes. Palpi black, edged with whitish, 

 ^closely scaled, erect, reaching above the eyes; the third joint long 

 -and cylindrical. Antennas simple in both sexes ; collar, thorax and 

 anterior wings closely scaled, and of a peculiar dull yellow, like the 

 color of brick when only partially burnt. Collar orbicular, with a 

 ■central, fine, very distinct, black rounded line on each side; behind 

 the collar a flat, rounded, closely scaled plate (corresponding to the 

 crest in many species), also with a black central line. Abdomen with 

 a very short tuft on the first segment. Anterior wings with the 

 .spots and lines indistinct and slightly marked. Interior and exte- 

 rior lines blackish, geminate, their component lines equally well 

 .marked, and separated by a wider interval than usual. The ordinary
