 with a black margin and nine black spots — viz. one large one at the shoulders, seven in the disk 

 arranged transversely 2, 3, 2, and one larger than the rest on the apical tumour; the humeral and 

 apical spots are glossy : three tawny-yellow mealy spots, the intermediate one straight and longi-

x. • Subgenus Trichinus. Kirb. 

 Trichini. Kirb. Zool. Journ. iii, 156, * *. 



The insects that compose this little group, as far as at present known, are all 

 North American ; and are distinguished from the legitimate Trichii (Legitimi K.) 

 by having the last joint of the palpi more slender, and the elytra hairy without 

 any of the bloom observable in those of T. fasciatus, Bigsbii, &c. The type of 

 the subgenus is T. piger Fab.
