 AcROLOPHUS viTELLTTS, Poey. (Plate XLI. fig. 11.) 



Acrolophus vitellus, Poey, Cent. Lp. Cuba, pi. (xx.) (1833); 

 Wlsm. Tr. Ent. Soc. Lond. 1887, p. 148. 



West Indies — Cuba (Poey) ; ? Portorico ( Wlsm.). 



A specimen in Dr. Staudinger's collection from Portorico agrees 

 with Poey's description in the structure of the palpi and antenna3 as 

 well as in neuration ; the fore wings have the usual indication of a 

 biangulate line along the neighbourhood of the fold, margined with 

 dark shades above and by the pale ground-colour below, this line 

 runs slenderly but distinctly to the base ; two angular dark shades 

 cross the fold, the outer one being connected on the left wing by 

 two lines of darker scales to the middle of the dorsal margin ; costal 

 margin distinctly spotted, the spots near the base taking the form 

 of waved strise reaching to the upper edge of the cell. The hind 

 tarsal joints are somewhat strongly clothed with tufts of scales, 

 reminding one of Thysanoscelis, Wlsm. I have not observed this 

 character in any other specimen of the same family from the West 

 Indies. The genital segments of this specimen are given on Plate 

 XLI. fig. 11. The uncus is double. 



Exp. al. 22 millim. 



Acrolophus poeyi, sp. n. (Plate XLI. fig. 12.) 



Antennce, tS , stout, simple, reaching to about two thirds the length 

 of the wing ; $ somewhat more slender than in the S • 



Palpi, c? , long and recurved, not thickly clothed and not reaching 

 so far as the back of the head ; umber-brown, tinged with whitish 

 ochreous beneath : 5 > projecting, conical. 



Head and thorax umber-brown. 



Fore ivings : S > umber-brown, with a few paler mottlings and 

 specklings of brownish ochreous along the costal and dorsal margins 

 and towards the apex, and with some small fuscous spots of scales 

 scattered throughout the wing ; costal margin narrowly brownish 

 ochreous throughout ; no particular pattern is visible on the wing, 

 but there is a tendency in the distribution of the blackish scale-spots 

 to form a sinuous dividing line along the fold, leaving the dorsal 

 portion below it of the paler tint ; cilia brownish ochreous, with a 

 dark line running thi'ough their middle : 5 almost unicolorous pale 

 umber-brown, having a less mottled or speckled appearance than 

 the 6. 



Hind wings umber-brown, with cilia of the same colour. 



Abdomen MxnhQx-hvovia. Genital segments, S : uncus single, bent 

 over at right angles ; lateral claspers slender and of almost even width 

 throughout, rounded at the ends and not projecting beyond the 

 uncus. 



Legs greyish ; hind tarsal joints speckled alternately with umber- 

 brown and subochreous ; hind tibiae slightly hairy. 



Exp.al. S 10-12 miUim., $ 11-18 millim.
