2iS LEPIDOPTERA. 



having its fore wings rich yellow, ochreous, or whitish-yellow, 

 and varying paler, with the hind wings dark grey and pale 

 yellow, pretty equally divided. But in this species the dark 

 grey colour of the hind wings on the uiulcr side appears 

 always to run to long jagged points along the nervures ; while 

 in all the L. 'pygmmola which I have examined, including 

 yellow specimens in Dr. Mason's collection, the grey colour is 

 softly and regularly shaded off into the pale yellowish or 

 whitish. In the male of L. lutarella, moreover, the antennae 

 appear to be always njore strongly ciliated with longer, dis- 

 tant bristles. In Professor Zeller's collection (presented by 

 Lord Walsingham to the British Museum) are numerous 

 L. lutarella, including a pale variety, but all evidently dis- 

 tinct from L. 'pyjmmola, which last is present in the collection 

 under the name Succia, Boheman. Herrich-Schafier and 

 Guenee appear to agree as to the distinctness of the two. 

 July and August. 



Larva short and rather thick, tapering a little behind ; 

 brown on the back, with a thick black dorsal line ; subdorsal 

 lines dark brown ; sides rather paler brown, with a dirty 

 white line along the spiracles. The tubercles with short 

 brown hairs, and the head black. (Buckler.) 



August to June. Supposed to feed on lichens growing on 

 the ground among moss, but the larv£e in confinement were 

 not reared. 



Pupa undescribed. 



The moth is sluggish, sitting upon the ground among 

 lichens, moss, and coarse grasses upon sea-sandhills. At dusk 

 it flies for a short time, then sits about upon the marram 

 grass and other plants, looking much like a Crambus, and 

 flies again late at night. It was first discovered about the 

 year 181'7 on the extensive sandhills near Deal, Kent, and 

 although constantly collected there has maintained itself up 

 to the present time. No other British locality is known.
