TORTRICINA. 67 



divided by the dorsal line, and at the base two larger and darker 

 undefined markings. The spots are of a slightly paler colour 

 than the rest of the body, elevated, and with the centres dark ; a 

 luteous hair springs from each. Before assuming the pupa 

 state it spins a slight cocoon of white silk. 



Genus III. PTYCHOLOMA, LEACH. 



Head short. Eyes small. Palpi as long as the head ; basal joint 

 very stout, curved, truncate ; apical minute, subglobose, not so long 

 as the basal ; middle stout, curved, slightly thickened in the middle, 

 more than three times as long as the apical, densely clothed with 

 short scales. Maxilla3 short. Thorax stout, globose, not tufted. 

 Anterior wings : length more than twice the breadth. Costa in the 

 c? broadly folded to the middle, and straight beyond ; in the $ re- 

 gularly arcuated throughout. Apex obtuse. Apical margin truncate, 

 oblique, and rounded ; dorsal margin straight. The costal vein does 

 not extend beyond the fold. The discoidal cell reaches beyond the 

 middle of the wing. Posterior wings : apex obtuse ; apical margin 

 rounded ; dorsal margin slightly concave ; basal angle produced. 

 Abdomen robust in both sexes, stoutest in the ; apex tufted in 

 therf. 



There is only one species known in this genus : the singular 

 furry appearance of the anterior wings is a peculiarity found in 

 but few of the Tortrices. The costal fold is broader than in Lozo- 

 t&nia, and the rounded apical margin of the posterior wings is a 

 distinctive character, and in the palpi it differs from that genus 

 by having the middle joint more than three times as long as the 

 apical, instead of three times only.

 medio characteribus 7*1, argenteis ; posticis brunneo-fuliginosis. 

 3 Exp. al. 6f-9| lin. 



Head varying from ochreous to fuscous, mixed with dusky scales 

 over the eyes and behind the antennae. Face grey. Eyes black. 

 Palpi varying from ochreous to whitish, frequently drab. Antennae 

 fuscous. Thorax varying from ochreous to fuscous. Patagia some- 

 what paler. Anterior wings dull, with a furry appearance, the 

 apical half obscure brown, the basal half paler, being more or less 

 irrorated with ochreous scales ; on the disk are three silvery marks, 

 together forming the figures 7*1 : these marks are more or less 

 distinct in different specimens, and sometimes wholly wanting; 

 sometimes the irroration of ochreous scales is ferruginous, and more 

 or less over the whole wing. Apical scales dark brown. Cilia
