 parallel to, and below Rs distally, slightly waved as it crosses 

 each branch of Rs; a long and slightly curved stripe along the 

 main stem of Cu to the fork, where it is thickened, and thence 

 along Cui-f M2, gradually tapering to a fine streak, and finally 

 bending slightly up to cross Mj, and to run wavily for 3 mm. up 

 across two branches of Us; also a short, curved stripe placed
