TORTRICINA. 155 



presented, at others almost entirely absent, or one or two black spots 

 in its stead. Apical scales orange, cilia white, both merging into 

 grey at and beyond the anal angle. Posterior wings shining pale 

 yellow, whitish at the base. Marginal scales paler. Cilia white. Ab- 

 domen and caudal tuft yellow. Exp. al. 5-7 lin. Anterior wings 

 marked and reticulated as in the rf , but with the slender costal 

 streak and dorsal blotch very much darker; this latter is some- 

 times of a deep fuscous brown and not reticulated like the remainder 

 of the surface. 



A very common insect, and distinguished from all the other 

 species of the genus by its smaller size and the beautiful sharp 

 reticulation of the anterior wings. 



The imago appears in June and July among Maple (Acer 

 campestre), and occurs chiefly in the south of England and in the 

 metropolitan district, also in Cheshire. 



The pupa is yellow, of the same colour as the imago, the wing- 

 cases of richer tint than the abdomen. The puparium or outer 

 covering is very diaphanous, and of a dirty-white colour, thus 

 permitting the enclosed insect to be seen through it. It is 

 about 4 lines in length. 



The larva is to be found full-fed towards the end of June in 

 the folded leaves of the Maple : while feeding it rolls the leaves 

 clumsily and longitudinally. In colour it is pale transparent 

 yellow, brighter at the extremities. The head pale yellowish 

 green, immaculate and shining; labrum yellow; mandibles brown; 

 the shield is slightly greener than the head ; the spots on the 

 body are very minute and whitish. Before assuming the pupa 

 state it neatly folds one of the lobes of the Maple leaf and spins it 



closely down with a white shininq silk,

Obs. : It is remarkable that the larva, pupa, and imago of 

 this species are all of the same colour : a coincidence, we believe, 

 which does not occur in any other known British species among 

 the Tortricina. 



3. Holiniana, Linn. Alis anticis aurantiacis apice plumbeis ; macula 

 dentiformi pone medium costaB nivea ; posticis griseis, apice satu- 

 ratioribus. <3 Exp. al. 6 lin. 



Head and face dull testaceous yellow, or pale ferruginous, the latter 

 slightly paler below. Eyes black. Palpi above and at the sides 

 same colour as the head, beneath straw-colour at the base, slightly 

 ferruginous at the apex. Antennae drab above, fuscous beneath, the 

 basal joint, and a few succeeding ones above, clothed with ochreous 

 scales. Thorax variable, from testaceous yellow to reddish ochreous, 

 usually darkest in front. Patagia same colours as the thorax. Ante-
