AND THEIR TRANSFORMATIONS. 107 



Family TORTRICIDiE, Leach. 

 This is a very natural family of large extent, corresponding with tlie section Tordeuses of Latreille, Platyo- 

 mides of Duponchel, and Pyralides of the other French writers ; and having broad entire fore winws, which, 

 vyhen closed, form a slightly deflexed triangle, with the shoulders dilated. The maxillary palpi are never 

 prominent, although possessed by many of the species ; the labial palpi, on the other hand, are broad and very 

 compressed, especially the middle joint, which is curved above, the last joint being short, and often more distinct 

 and exposed ; they are never recurved, but generally form a short beak in front of the head ; the spiral tongue 

 is short in the majority. The body is comparatively slender ; the thorax rarely crested ; the antennas simple, 

 or but slightly ciliated in a few species : the fore legs generally have a central tibial spur ; the middle tibiae one 

 pair of spurs at the tips ; and the hind tibiee two pairs. The wings, in some species, are ornamented with tufts 

 of raised scales ; and, in one genus, they are deeply notched on the fore margin. The larvae are naked and 

 fleshy, with 6 pectoral, 8 ventral, and 2 anal feet ; and, for the most part, they take up their abode in a leaf 

 curled up by the insect itself, and fastened with silken threads, forming a cylindrical tube open at each end, 

 which thus serves for food and abode : others frequent the young buds and shoots of various plants, fastening 

 several of the young leaves together so firmly as to impede their growth, and occasionally to be of serious 

 injury to the plant, by destroying the parts of fructification and bloom. This is especially the case with Pcedisca 

 angustiorana (which thus injures the apricot *) ; Argyrotoza Bergmanniana, a beautiful little species, which, in 

 like manner, infests the rose f ; and Tortrix vitana Bosc, which is extremely obnoxious in the vine plantations in 

 the South of France, and which aflbrded to the late Professor Audouin the subject of one of the most elaborate 

 and beautifully-executed and illustrated memoirs which has hitherto been published. Others, again, reside 

 within the pulpy substance of various fruits, especially tlie apple and plum, to which they are sometimes very 

 detrimental.

 The whole of the insects in this plate are from the cabinet of Mr. 

 Bentley. The caterpillars, with the exception of that of Prasinana, 

 from Sepp, are from Hiibner. H. N. H.

The insects of this genus are the largest belonging to the present famUy, and are further distinguished by the 



lovely green colour of their fore wings, marked with pale oblique stripes. They, however, oSer a striking 



instance that the largest and most conspicuous insects in a group are not to be necessarily considered as its 



pre-eminent types ; indeed, the very circumstance of their gigantic size is of itself one proof of aberration.
