152 Mr. H. T. Stainton on the Species of the 



Ex^RETiA, nov. gen. 



Caput Isevigatum. Palpi recurvati, articulo secundo infra setis 

 instructo, articulo terniinali acuto. Antennce mediocres. 

 Alee anteriores latae ; ante ap'icem aliquantulum contractce ; 

 cilia brevia, ad marginem posteriorem emarginata. Alee pos- 

 teriores elongatae, ovales, emarginatse ad angulum anale ; 

 cilia brevia. Abdomen depressum. 



This genus is intermediate between the Stenoma of Zeller (an 

 exotic genus) and Depressaria ; in Stenoma "the anterior wings 

 are broad before the middle, posteriorly narrowed ;" in Depres- 

 saria they are, to use Zeller's words, " almost widened poste- 

 riorly," whereas in Excsretia they are narrowed beyond the mid- 

 dle and then again expanded ; the cilia are much shorter than in 

 Depressaria, in this respect resembling Stenoma. 



Allisella, n. sp. (PI. XVII. fig. 1.) 



Alse anteriores plumbeae ; stria rufa obliqua a costa ante me- 

 dium ; macula magna triangulare rufescente ante apicem, 

 quae supra costam stat, marginem interiorem suo apice tan- 

 gens ; in margine interiore hujus maculae, quae distinctior est, 

 Stat linea nigra obliqua. 



This species is very distinct from any with which I am ac- 

 quainted, and has at first sight somewhat the appearance of a 

 Peronea. 



Expansion of the wings 10 — 11 lines. 



Head ashy-grey. Face ashy-grey. Palpi, the second joint is 

 on the upper side whitish, smooth ; on the under side thickly 

 clothed with ashy-grey bristles ; terminal joint dark tawny, not 

 annulated. Antennas grey. Thorax greyish. Abdomen greyish, 

 with a large black spot in the middle ; the anal tuft is yellowish. 

 Legs and tarsi brownish on the outside, whitish inside. Anterior 

 wings rather glossy leaden grey, with a rosy tint at the base to- 

 ward the inner margin ; a little before the middle is a short oblique 

 rosy streak proceeding from the costa, and reaching only half 

 across tlie wing, it terminates in a darker spot ; parallel to this, a 

 little beyond the middle, is a similar streak which reaches to the 

 anal angle, and has in it a short black linear blotch; beyond this 

 streak the entire apical portion of the wing is more or less suf- 

 fused with reddish, and a darker shade proceeds from the anal 

 angle to the apex, forming the outer side of the triangular blotch; 

 the portion of the disk immediately following the black spot is
