{Continued from Vol. xx,p. 270). 



Toy^trix Branderiana, L. — Larva stout, each segment thickened, 

 especially the third and fourth, and tapering thence to the anal seg- 



laaent. Colour dirty pale green, spots minute, black, with small hairs. 

 Head and plates black, the dorsal plate having in front a white collar. 

 Pupa blackish. Feeding between united leaves of aspen. The larva 

 iescribed — the only one that I have seen — was sent by Mr. Hodgkinson 



■ 3f Preston, who reared others. This one did not produce the perfect 

 nsect. 



Zeller describes this larva : " slender, very active, when young 

 nearly black, with raised dots of the same colour bearing hairs ; when 



, Eull-grown, head, dorsal plate and claw-feet black, the dorsal bordered 



Sm front with white. In May in a folded leaf of Fopulus tremula.'' 



Pe7V7iea mixtana, Hiib. — Larva active, cylindrical, rather slender, 

 j^ellowish-green with green dorsal vessel. Head yellowish-brown, 

 plates bright green. On Calluna vulgaris in the beginning of August, 

 drawing together the terminal shoots and forming a chamber among 

 them in which it lives, coming out — apparently at night — to feed on 

 the tips. Pupa dark brown, in a slight cocoon in the same place. The 

 moths emerged early in November. 



These larvae were found in Scotland by my old friend Dr. Algernon 

 Chapman, who very kindly forwarded them to me. 



Teras contaminana.^ Hiib. — Sluggish and rather plump, slightly 

 flattened, when young pale green with head and dorsal plate black, 

 when older the head becomes brown, and when full-grown the body 

 :becomes almost yellowish, the head pale brown, and the dorsal plate 

 yellowish, anal plate green at all ages. 



Yery plentiful in June drawing together leaves and terminal shoots 

 of hawthorn and blackthorn, and feeding between them. Becoming a 

 brown pupa in the same place. 



Zeller says it feeds on wild apple, plum, pear, sloe, oak, and 

 mountain ash. 



Dictyopteryx Bergmanniana, L. — Larva cylindrical, when young 



pale greenish grey, paler beneath, sometimes even bluish when very 



young, head and both plates black and shining. At this time it com- 



j jmonly folds together a leaflet of rose and lives between. When older 



it often becomes yellow, sometimes very bright yellow, and the anal
