168 THE GENERA OF BRITISH MOTHS. 
Micropleryx purpurella (the Purple Upper Wing, No. 11). The Caterpillar of this pretty species is 
unknown. The perfect insect appears in April, and has been recently taken in plenty at Plymouth, Teignmouth, 
York, and other places. 
The other species are M. Calthella ; M. Aruncella; M. Seppella ; M. Mansuetella ; M. Allionella ; M. 
Tunbergella ; M. Salopiclla ; M. semipurpurella ; M. unimaculella ; M. Sparmannella. Among these many are 
very richly coloured, with golden green and purple hues of a metallic lustre, especially M. Alionella, with purple 
wings varied by pale golden bars and spots ; waimaculella has the front wings pale golden suffused with purple. 
The genus Nemophora. One of the principal characteristics of the insects of this genus is the length of 
the antenne, which is more than double that of the wings. The maxillary palpi are folded ; the labial palpi 
short and hairy, The hind-wings have hair-like scales at the base. The Caterpillars have a case of depressed, or 
rather flattened form. 
Nemophora Swammerdammella (the Swammerdamian, No. 12). The wings of this species have a fine semi- 
metallic gloss, The Caterpillar is whitish and semitransparent, with the head and second segment black, and 
narrow purplish-brown plates ‘on the third and fourth segments. It forms a case of particles of dried leaves, and 
feeds on various plants. It is common and has been recently taken in abundance at Tenterden in Kent, 
Plymouth, Bristol, and many other places. 
The genus Adela. To this genus, like the last, insects are assigned which are at once distinguished hy 
the extraordinary length of the antenne, those of the males being considerably longer than those of the females. 
The colour of most of the species is very brilliant. The Caterpillar forms a flat case. 
Adela De Geerella (the De Geerean, No, 13). The Caterpillar of this handsome and remarkable species is 
yellowish-white, with a black head, and is said to feed in October and March on the Wood Anemone. The Chrysalis 
shows the long antenne coiled in a roll at the extremity of the abdomen. The perfect insect appears in June, 
and is common and widely dispersed. It has been recently taken in great plenty at Lewes, Plymouth, &c., &e., 
The Caterpillar, the Chrysalis, and the Cocoon are represented at Nos. 14, 15, and 16. 
The other species are, A. Pibulella; A. rufimitrella ; A, Sulzlla; A. viridella; A. cuprella ; among 
which A. viridella, with its extremely long antenne and front-wings of resplendent golden green, with a brilliant 
metallic gloss, is perhaps the handsomest. 
The genus Nemotois. The insects assigned to this genus have the antenne of great length in the males, 
but not so long in the females, though sometimes, in that sex, thickened at the base. The eyes in the males are 
large and close together ; but in the females, smaller and widely separated. There are four British species. 
Nemotois fasciellus (the Copper Japan, No. 17). The Caterpillar of this handsome inseet is unknown ; 
the brilliant coppery gloss of the wings, which become greenish-golden at the base, gives them a very brilliant 
and attractive appearance. The head of the male is black, that of the female ferruginous. The Moth appears in 
June and July, and has been recently taken in Darenth Wood, Kent. 
The other species are VN. Scabiosellus, N. cupriacellus, and N. minimellus, all of which are remarkable for 
the fine golden or bronze-like gloss of the wings, varying from reddish purple to every shade of orange and green, 
but with few markings.
