Genera and Species of Exotic Trichoptera. 249 
orange hairs; app. sup. short and subtriangular; app. intermed. 
very long, straight and needle-shaped, deep testaceous; app. inf. 
in the form of a rounded basal piece, whence proceeds a short, 
curved and acute spine; ventral lamina broadly rounded, In the 
female the inferior valves are elongated, subtriangular, and some- 
what acute, 
Variety of the female: a broad, blackish fuscous band runs 
through the middle of the anterior wings from the base to the 
apex, enclosing a conspicuous pale spot at the thyridium. 
This beautiful species in form and structure agrees with the 
European P. grandis, excepting in the excised apical margin of the 
anterior wings. In coloration it bears a remarkable resemblance 
to Colpomera sinensis (Trans. Ent. Soc. 3rd ser. i. 302) from 
North China, but the latter species differs in its narrow and sub- 
falcate anterior wings and in the produced apex of the posterior. 
The discovery of P. japonica has convinced me that Colpomera 
can, at the utmost, be considered only as a section of Phryganea, 
because in P. japonica there is clearly to be seen an approach to- 
wards the alar formation of Colpomera in the excised apical margin 
of the anterior wing, and the similarity of coloration is so striking 
as to suggest the idea of the one being remotely descended from 
the other.
