Myelois. Imago with forewings elongate -triangular, costa 

 gently arched. 



1. C. terebrella, Zk. 20-23 mm. Forewings rather dark 

 fuscous ; lines white, first nearly straight, oblique, second 

 slendei", twice indented ; a suffused whitish fascia near before 

 second line, broader and more distinct towards costa, including

Norfolk, local ; G. Europe ; 7, 8. Larva whitish ; dorsal 

 line dark grey ; dots black ; head and plate of 2 light reddish-

16. HOMOEOSOMA, Curt. 



Face with short scale-projection. Antennae in S shortly 

 ciliated, with a notch above basal joint. Labial palpi moder- 

 ately long, arched, ascending, with tolerably appressed scales, 

 terminal joint rather short, tolerably pointed. Maxillary palpi 

 moderate, loosely scaled. Forewings : 4 and 5 stalked, 9 absent. 

 Hindwings : cell not nearly reaching i, 3 and 4 approximated 

 or connate, 5 absent, 7 anastomosing with 8 to near apex. 



Not numerous in species, but of cosmopolitan occurrence. 

 Imago with forewings narrow, costa hardly arched. Larva 

 usually feeding in heads of Compositae ; possibly the ready 

 distribution of the seeds of these plants by the wind may 

 account for the wide range of the genus, since the eggs might 

 be transported with the seeds.
