176 THE GENERA OF BRITISH MOTHS. 
The other species, C. striatella, has the front wings of a grayish tone. The Caterpillar feeds on the stems 
of the Tansy. 
The genus Chelavia. The insects assigned to this genus have the second joint of the labial palpi tufted, 
the terminal joint partly furnished with scales, but smooth and pointed at the tip, so as to resemble slightly 
the claw of a lobster, from which both the generic title and the popular name of the British species are derived. 
The front wings are moderately narrow, and the hinder pair acute at the tips, and slightly indented in the fringed 
margin. There is only one British species. 
Chelaria Hulmerelia (the Lobster-clawed, No. 11). The Caterpillar of this species remains undescribed, 
though the perfect insect iscommon. It appears in September and October, and has been recently observed in 
great abundance at Bristol, Darenth Wood, and Scarborough, and as Mr. Stainton informs us, at Newcastle, in 
July. 
The genus Anarsia. The insects assigned to this genus have the second joint of the labial palpi tufted 
and scaly, and the terminal joint short and, in the male, nearly concealed in the scales of the long second. The 
female has the terminal joint of the palpi long and pointed. The hind wings are slightly indented at the fringed 
edge. There are two British species. 
Anarsia Spartiella (the Furze Anarsia, No. 12). The Caterpillar of this species is described as dull brown, 
with the head and second segment nearly black. It feeds on the young shoots of Broom and Furze in June, and 
the perfect insect appears in July. It has been recently observed in great abundance on Wimbledon Common, 
and has been taken at many other places. 
The other species, A. Geniste, closely resembles A. Spartiella, but is much darker.
