TORTRICINA. O 



subserrate and plumose), stoutest and pubescent beneath in 

 the tf . Never so long as the anterior wings. 



Thorax usually stout, globose or ovate; sometimes with a crest 

 (simple or bifid) behind. 



Patagia two never longer than the thorax, covering the bases of 

 the anterior wings. 



Wings four. The anterior pair varying in length and breadth, of 

 obovate or elongate triangular shape; frequently truncate at 

 the apex, ornamented with markings of various colours, usually 

 dull, but sometimes with metallic lustred spots and streaks. 

 The discoidal cell always obtuse at the apex, never ? attaining to 

 three-fourths the length of the anterior wing, and usually lying 

 more towards the upper half than in the middle. The posterior 

 pair always shorter than the anterior, but frequently much 

 wider ; always of sombre colours, and without markings ; 

 folded in repose. Cilia ample. 



Legs formed for walking: the first, or anterior pair, simple and 

 shortest ; the second, or intermediate pair, with two unequal 

 moveable spines at the apex of the tibia ; the third, or posterior 

 pair, with the tibia armed with two pairs of unequal moveable 

 spines, one pair situate beyond the middle, the other at the 

 apex of the tibia. These spines are directed downwards, and 

 inserted on the under or inner surface. 



Tarsi five-jointed, terminated by two minute claws. 



Abdomen moderately stout in both sexes, but usually more robust in 

 the ; generally with a caudal tuft in the <$ . 



PUPA obtected, robust ; enclosed in a cocoon or web spun by the 

 larva (never exposed, suspended or girt). The abdominal seg- 

 ments armed with transverse rows of minute spines (except 

 Sarrothripa) ; caudal extremity frequently armed with spines, 

 hooks, or tentacula. 



LARVA always ? with 16 feet, 6 pectoral, 8 abdominal, and 2 anal 

 (sometimes these organs are only rudimentary). Head and 

 shield horny, and frequently with a horny plate on the anal 

 segment above. 



OVA usually scale-like. 



The colouring of the British Tortridna is very varied, and 

 although generally of tints which may be designated sombre, these 

 insects are certainly equal in beauty to any found upon the Conti- 

 nent, and scarcely less gay than most of the few we are acquainted 

 with from extra-European localities. The markings, however, 

 are extremely simple ; being, as in some of the other families in 

 this Order, a modification of an almost universal type through- 

 out. These consist of a basal patch, a central fascia, a spot or 

 mark upon the costa towards the apex, and an ocellated patch 

 at the anal angle, with one or two others of minor importance :
