median lines are evident, black and finely dentate, followed by indis- 

 tinct whitish shade lines; the subterminal line irregular, preceded by 

 a deepening of the ground color; the orbicular spot absent, the reni- 

 form large, round, and pure white, forming the most prominent fea- 

 ture of the ornamentation. Posterior wings uniform dark fuscous, 

 with light fringes. Beneath gray, suffused with ochreous, and with 

 numerous scattered black atoms; on the anterior wings the exterior 

 line is visible on the costa ; the posteriors have a clear, black, discal 

 dot, and a regular, finely dentate, median line. 



Hab. Waco, Texas. 



The contrasting white reniform spot will always separate this spe- 

 cies from the rest of the genus. 



8. Caradrina disticha no v. sp. 



Expanse 27 mm. Length of body 14 mm. 



Eyes naked. Palpi ochreous, the third joint short. Front and 

 thorax smooth, concolorous and untufted. Abdomen untufted, in the 

 female with a short projecting ovipositor. Anterior wings light gray, 

 sprinkled with numerous black atoms to the median shade, which is 

 perfectly straight, oblique, inwardly clearly defined, and followed by 

 a dark, blackish-gray ground color, which contrasts very strongly 

 with the preceding light gray region; this continues as far as the ex- 

 terior line, beyond which the ground color lessens in depth, returning 

 to the original light gray color; interior line dark gray, geminate, and 

 even, forming a single inward indentation below the median nervure; 

 orbicular and claviform spots obsolete; the reniform large, subquad- 

 rate, light ochreous gray, contrasting with the dark ground color; ex- 

 terior line even, broadly undulate, geminate, dark gray, enclosing a 

 pale shade line; two conspicuous, clear black, cuneiform, subapical 

 markings, one much larger than the other; below them a black spot; 

 the terminal space darker gray. Posterior wings gray at the base, 

 melting into uniform black ; all markings absent. Beneath dark 

 gray, with innumerable scattered black atoms; the usual discal dots 

 are present on the posterior wings. 



Hab. Waco, Texas. 



The ornamentation in this species is so simple and defined that it 

 will hardly be possible to mistake it. 



TORNOS nov. genus. 



We found this genus for a slender built geometriform insect, which 

 we place near Adipsophanes and Crambodes on account of the compar-
