This species, although resembling stdbilis in its style of ornamenta- 

 tion, belongs to quite a different section of the genus. It is separated 

 from the typical Tceniocampce by the peculiar structure of the palpi 

 an i the more slender form. 



THAUMATOPSIS nov, gen. 



I erect this genus for a very peculiar Noctuid allied to Doryodes 

 and Sudariphora, but more closely approaching the former. The 

 following are its characters: Form slight. Habitus and markings 

 resembling Crambus. Ocelli present. The head wide, with the 

 front slightly rounded. The male antennse are clothed with long 

 slender pectinations, as in Doryodes. The palpi are exceedingly long 

 (5 mm.) , horizontal and closely scaled. The first joint of normal 

 length; the second comparatively thick, very long, and slightly com- 

 pressed ; the third slender, long and needle-shaped. The eyes are 

 naked. The thorax is weak, rounded, with scaly clothing. The ab- 

 domen is slender, long, and untufted. The legs are long, having the 

 tibiae non-spinose and closely scaled. 



The anterior wings are narrow, with subrectangular apices. The 

 posterior are comparatively broad, with all the angles rounded. 



Thaumatopsis longipalpus nov. sp. 



Expanse 32 mm. Length of body 19 mm. (including palpi). 



Thorax and anterior wings with the ground color as in the com- 

 mon Doryodes acutaria H. S. Along the costa the anterior wings 

 are ochreous .to the exterior line. The median nervure from the base 

 to the divarication of the first median nervule is covered by a clear 

 white streak, as in acutaria. Above the nervule, from the median 

 space to the apex, there extends a black shade, at first distinct and 

 definite, contrasting with the white streak, but afterward becoming 

 diffuse. Below the median nervure, from the base to the middle of 

 the median space, there is a similar black shade, which limits above 

 an ochreous streak extending to the exterior line. The ordinary 

 spots and all the lines are obsolete, except the exterior line ; this is, 

 however, represented only by a series of black dots on the nervules. 

 The latter are more or less distinctly tinged with blackish. The pos-
