abdominal margin, a dark sub-apical spot, and some dark patches at 

 the middle of wing. Thorax, abdomen and legs concolorous; the

9 . Very different in color, which is here golden testaceous. The 

 lines are all the same as in the $ , but there are no orange blotches; a 

 whitish triangular patch in the middle of the costa; fringes alternately 

 golden-brown and dull yellow. Secondaries darker than the fore 

 wings, with a still darker median shade. Beneath, the wings are 

 marked as in the S , but the shading has an olivaceous tint, and the 

 bands, etc., are not so distinct. Legs, abdomen and thorax concolor- 

 ous. In both sexes the discal mark is a whitish cloud. 2 9 . 



Exp. wings 48 mm. Length of body 25 mm. 



A yery beautiful insect, beyond all doubt referable to Packard's 

 genus. 



Acronyctodes, n. genus. — Closely allied to Apatclodcs, Pack., but 

 differs in the following particulars: The fore wings are longer propor- 

 tionately in their costal length, acutely produced at the apex, without 

 the excavation on margin so visible in Apatelodes, and the posterior 

 margin is more oblique to the internal angle. The feet and legs are 

 less densely clothed with hair, and the abdomen is a little longer. 

 Palpi shorter and more .slender, and the antennae with pectinations 

 smaller than in the $ of Apatelodes, while those of the 9 have the 

 pectinations longer than the 9 of Apatelodes. Markings somewhat 

 similar, but less pronounced. Hind wings slightly hyaline. 



Acronyctodes insignita, n. sp. — $. Grayish white, with darker 

 markings. A black basal line most apparent on costa; a broad median 

 space, enclosing black discal spot, behind which is a blackish cloud. 

 The sub-marginal line is whitish, edged in front with black, dentated; 

 near its apical extremity are three small almost ecjual teeth. The space 

 behind this line is grayish, with darker shades, and the terminations of 

 the ner\'ules are marked by black points. Near the apex, and along- 

 internal margin are some faint fawn-color shades. Secondaries dull 

 grayish, with a small black discal spot, and a faint median dentated 

 line. Beneath, wholly gray, like many species of Apatela, with faint 

 sub-marginal lines, and black discal spots on both wings. Head gray 

 in front; thorax, legs and abdomen concolorous. 2 $ . 



Exp. wings 42 mm. Length of body 25 mm. 



9 . Paler gray than the other sex, the thorax and abdomen being- 

 sordid white. The markings similar to those of the c? , but a little 

 darker behind the middle. 2 9 . 



Exp. wings 55 mm. Length of body 25 mm.
