the Similkameen river. It is thought, however, from what is revealed 

 by the description and illustration, that several species are included 

 under this name.

Etoptychoptera tertiaria, gen. et sp. nov. Fig. 30. 



Locality: Tulameen river, opposite Vermilion cliff — (August 6, 

 1906. L.M.L.). 



A portion of a wing 12"™ long, the entire length of which may- 

 have been about 14™". The anterior border is nearly straight, while 

 the apical and posterior margins are distinctly rounded. The costa, 

 subcdsta, and radius lie very close to each other and are nearly 

 parallel. The subcosta extends almost two-thirds the length of the 

 wing and fuses in the costa. The radius continues nearly to the 

 apex of the wing and fuses unb'ranched in the apical margin. Its 

 ssector originates quite n&ar the base of the wing, and at one-third 

 the length of the wing it iseparates into two widely divergent trunks, 

 the anterior of which forms a long terminal fork, while the posterior 

 branch divides into two short twigs, so that four b'ranchleta are 

 present. The media takes its course nearly through 'the centre of

the wing, and at one-third the wing's length it furcates into two 

 main branches, the anterior of which is slightly arcua'te and is par- 

 allel with the posterior branch of the sector; it fuses at the end of 

 the posterior margin, and, if I mistake not, forms 'a short terminal 

 fork. The posterior branch of the media, however, isues obliquely 

 toward the anterior branch of the cubitus, with which it unites 

 nearly at right angles; after a short commdn course these again 

 separate, the posterior branch of the media curving toward the 

 posterior margin and forming a short bifurcation, while the anterior
