70 TLUTELLID.E. 



riorly attenuated ; tlie apical vein is furcate. The larva forms a close 

 silken cocoon. 



The insects of tliis genus appear at the end of summer and au- 

 tumn ; many of the late species hybernating, and being again met 

 with in the sprmg; when at rest they are easily disturbed, but 

 generally drop ouly from one portion of the busli or hedge to 

 another, and rarely make use of their wings. The larva of C. 

 a-ylodclla (green, with a broad red stripe on the back) is the most 

 g(!nerally met with : it is attenuated anteriorly, extremely active, 

 and, when full-fed, constructs a very firm, close silken cocoon. 



The iieuration of the anterior wings is not identical in all the 

 species," as may be seen from the following table : — 



A. Apical vehi furcate; below it five veins from the discoidal cell. 

 B. The three lowermost of these v(,nus are not miited at their origin. 



Species 1-5. 

 B n. The two lowermost of these veins are united at their orii^'iu. 

 Species 11, 12. 

 A A. Apical vein simple ; below it six veins from the discoidal coll. 

 c. The tlsree lowest of these veins are not united at their origin. 



Species 7. 

 c c. The penultimate and antepenultimate of these veins, proceed 

 from the same point. Species G, 8-10. 



The t,welve British species may (v/ithout denuding the wings) 

 be placed in the following table : — 



a. The cilia of the anterior wings not retuse below the apex. Sp. 1-4. 

 a a. The cilia of the anterior Avings retuse below the apex. Sp. 5-7. 

 a a a. The anterior wings slightly caudate. Species 8-10. 

 n a n a. The anterior wings caudate. Species 11, 12.

.llca(b tace, and palpi white. Antenme blackish. Anterior wings 

 while, with an indented black hlotch on the inner margin, reaching be- 

 yond the middle ; at the base and between the indentations it touches 

 the fold, and at its hinder end it crosses the fold ; along the costa are 

 several short black streaks, a more conspicuous one in the middle, 

 slo])ing inwardly, reaches nearly half across the wing, and an irregular 

 black mark beyond the middle of the costa, almost unites with the ter- 

 mination of tlie blotch on the inner margin ; along the apex of the costa 

 and hinder margin, and at the anal angle, are some black or hlackish 

 marks; cilia wliite at the apex, in the middle of the hinder margin 

 and at the anal angle hlackish. Posterior wings grey, witii paler cilia.
