Acronycta qiiadrata Grote. 



Q . — A large species, allied to the typical forms of the genus, with distinct 

 ornamentation. Fore wings whitish gray with a distinct deep black longitu- 

 dinal basal streak extending to the geminate, nearly even, suboblique t. a. line. 

 Median shade noticeable from its position being nearer to the t. a. line on in- 

 ternal margin than to the t. p. line. Ordinary spots vaguely outlined, appar- 

 ently large, with a distinct block of black scales between them on the cell. 

 The median space is wide. The t. p. line is nearly erect and even, slightly 

 outwardly exserted superiorly. A distinct black dash above internal angle 

 from the t. p. line, crossing the subterminal. Subterminal space darker than 

 the rest of the wing. A short black dash on the s. t. line opposite the cell. 

 An even blackish terminal line. Hind wings pale, with fuscous terminal shad- 

 ing, without discal marks and on both wings beneath the usual markings are 

 faint. Head and thorax pale gray ; tegulae at the sides lined with blackish 

 and the sides of the thorax in front of the wings streaked with black. 



Exj^anse, 40 m. m. HaUtat, Kansas (Sept., from Prof. C. V. Eiley). 



Note. — On page eighty of the first Vohime of the Bulletin I have 

 shown that Guenee describes the Apatela americana of Harris as 

 Acronycta hastulifera {Ahh. £ Sm). On the other hand Harris 

 identifies his species as the accris of Abbot and Smith from the sim- 

 ilarity of the larvae. Prof. Riley has called my attention to his de- 

 scription of the larva of Harris' americana, which accords with Har- 

 ris and also with Abbot's figure of the larva of the species he calls 

 aceris. I find that Guenee has transposed, in his descriptions. Ab- 

 bot's larvae, perhaps unintentionally, but perhaps also correctly, and 

 since the figure of the imago of hastulifera strongly resembles amer- 

 icana, while the figure of the larva of aceris fairly represents the 

 larva of americana, these may be correctly associated under the name 

 hastulifera. It must be, however, doubtful, and I think we might 

 even prefer Harris' name with the following synonymy so far as 

 Guenee and Abbot and Smith are concerned.
