 222S (2). Stmmoca rosmarinella, sp. n. 



Antennre whitish cinereous, faintly banded above with bi'ownish fuscous. Palpi 

 recurved to a little above the vertex ; whitish cinereous, the median joint shaded 

 externally, nearly to the apex, with brownish fuscous, the terminal joint tipped with 

 brownisli fuscous, and with a very few brownish fuscous scales scattered over it. 

 Head woolly; dirty whitish. T'/zoraa; whitish cinereous, with some brownish fuscous 

 speckling. Fore-iobiqs about three times as long as wide ; whitish cinereous, 

 speckled with brownish fuscous ; with a small dark brownish fuscous patcli at the 

 base of the costa (sometimes continued as a shade along the fold), a similar patch 

 before the middle of the costa, and another beyond the middle ; a dark brownish- 

 fuscous spot in the fold, a little before its middle, connected upward and inward 

 with a more or less broken line of brownish fuscous scales, pointing rather obliquely 

 to the origin of the ante-median costal spot, but not connected with it ; beyond 

 this is a small brownish fuscous spot at the upper edge of the cell nearer to the 

 post-median than to the ante-wedinn costal spot ; a tornal spot of the same colour, 

 oppos<ite to the outer costal spot, is diffused upward parallel with the termen, forming 

 a rather conspicuous portion of terminal shading, which also extends around the 

 apex, but is broken into ill-defined spots along the margin ; the oblique streak 

 arising from the fold is outwardly bounded by a few pale ferruginous scales, similar 

 scales occurring at the end of tlie cell between the tornal and costal spots ; cilia 

 whitish cinereous, speckled with brownish fuscous scales, especially on their basal 

 half. Exp. n,l., ^,14; $ , Ifi mm. Hind-wings and cilia greyish brown. Abdo- 

 men and legs gi*eyish brown ; hind tarsi with indistinct paler spots.

Hnh. : S. Frat^ce, Beaulieu. Larva, Ros^nnrinus officinalis, 30, 

 IV, exel. 17—21, TX, 1890. Four specimens. 



The larva was found feeding in accumulations of di'y leaves and 

 rubbish, more or less connected by light webbing, about the stems 

 and branches of Rosmarinus officinalis at Beaulieu on April 30th, and 

 four specimens of the moth emerged from September 17th- 21st, 

 1890. I have no doubt this species could be easily found by those 

 who have an op])ortunity of visiting the promontory which projects 

 from Beaulieu along the eastern side of the Gulf of Villefranche. 



This species differs from sigiiafella, H.-S., in its tendency to 

 assume a rather darker shade, especially in the hind-wings, in its 

 rather more slender antennae, in the darkened apex of the terminal 

 joint of the palpi, and very consistently in the position of the small 

 spot on the upper edge of the cell, which in si(/nafel/a is nearer to
