ACRONYCTA INSOLITA Grote. 



Acronxjcta insolita Grote, Bull. Buff. Soc. Nat. Sci., 1873, I, p. 82. 

 Eulonche insolita Gkote, Papilio, 1883, III, p. 113. 



'^Eesembles A. ohlinita in the lanceolate primary wings, which are 

 even longer and more produced apically. Blackish; orbits of the eyes 

 white. Primaries uniformly blackish, the dark tone obscuring all orna- 

 mentation exce])t the transverse posterior and subterminal lines, which 

 are oblique and appear as rather broad intcrspaceal lunulated or squared 

 gray marks, which, in the as usual flexed transverse posterior line are 

 marked by black outward points, the fragments of the transverse 

 terminal line itself, the gray marks being the preceding shade. Hind 

 wings white beneath, with the costal region dusted with blackish scales. 

 Palpi with the second joint outwardly black; fore tibiae with blackish 

 longer hair. Abdomen whitish above, darker beneath, rather long. 

 The unusually dark color and pointed wings, together with the peculiar 

 appearance of the transverse lines, should make this species very 

 recognizable. This last section of the genus reminds us of Leucaiiia. 

 My specimen of .4.. insolita expands 1.60 inches. Coll. Am. Ent. Soc." 



This species is credited to '^Pennsylvania" and later to the "Middle 

 States." I marked it in my catalogue as in the British Museum, but 

 have no notes nor remembrance of the insect. I have seen nothing in 

 any collection accessible to me of any form agreeing with the above 

 description; the only one of the genus with which I am not personally 

 acquainted. 



ACRONYCTA DENTATA Grote. 

 (Plate XIII, fig. 11, femalo adult.) 

 Apatela dentata Grotk, Can. Ent., 1875, VII, p. 222. 



Male. — "This is allied to tritona and grisea, but is a smaller species 

 wanting all the black dashes. The ground color is blackish shaded 

 over with whitish. The lines black, single, denticulate. The claviform 

 is indicated by a slight black mark. Orbicular obsolete, iieniform 

 whitish, rounded, with its outer edge black-lined and shaded. Trans- 

 verse anterior line running in a little on median vein. Transverse 

 posterior line inaugurated a little above the reniform, running well 

 outwardly, denticulate throughout its length. Subterminal line hardly 

 apparent; a blackish shade over median nervules on the gray terminal 

 space. Fringes gray, preceded by blackish interspaceal markings. 

 Hind wings fuscous, lighter toward the base, with indistinct line.
