costal veiu is abruptly bent upwardly at base, thence following the cos- 

 tal edge to the apex of the wing. The subcostal vein is two and the 

 median three branched. The cell is open; the independent slight. 

 The submedian and internal veins are simple. The abdomen is short- 

 er than the internal margin of the secondaries. 



I take the Hesperiatarquinius of Fabricius (the PoJyommahis cratae- 

 gi of Boisduval and Leconte) as the type of the genus Feniseca. Con- 

 generic with Fen. tarquinius, and a second species of the genus, is Fen. 

 porsenna, considering Mr. Scudder's Poli/ommatus porsenna from New 

 Elngland in reality a distinct species. I have specimens of F. tarquin- 

 ius from Georgia and, on comparison, I cannot distinguish specifically 

 between them and material from Pennsylvania which I refer to this 

 same species. 



Above, the colors and ornamentation of Feniseca tarquinius some- 

 what resemble those of certain species of Hesperia, while reminding us 

 more strongly perhaps of Thecla (favonius), with which latter genus its 

 structural affinities lie. 



On a new Genus of HOCTUIDAE allied to DYOPS, with remarks on 



certain species of AGROTIS. 



BY A. R. GROTE. 



To a genus indicated, but not named, by Guenee, and for which the 

 term Litoprosopus is proposed, belong three species of Noctuidae with 

 ocellated secondaries allied to the South American Dyops, but distinct- 

 ively characterized by the smoothly and closely scaled elongate and 

 subspatulate third article of the labial palpi. 



In the South American Dyops ocellata, and D. oculigera, the labial 

 palpi are given as "a 3e article court, conique, confondu avec le prece- 

 dent" (Noct. Vol. 2, p. 283). It is noteworthy that while M. G-uenee 

 says : "Peut-etre faudra-t-il faire deux genres des trois especes qui com- 

 posent celui-ci (c. a. d. le genre Dyops)", and while the genus is divi- 

 ded by this Author into two Groups, no remark is made on the differ- 

 ences of palpal structure which I suppose induced the division of the 

 Genus into "Groupes," although, indeed, no reason at all is given in 

 Vol. VI of the Species General des Lepidopteres for the observation 

 (as above cited) or the procedure. 



The specific distinctiveness of all the three species described by Au- 

 thors and here enumerated, is assumed but not assured. The species 

 described by Guenee as Dyops Ilatuey, does not indeed seem to be the 

 Noctua Hatuey of Prof Poey, as suggested by Mr. Walker, who ap-
