They are somewhat smaller than those of R. Brittoniae but re- 
semble them more closely in other respects than they do those of 
R. phyllobola. Their divisions are broad and triangular and are 
usually tipped with a single cell, making them obtuse (FIGURE 22), 
in rarer cases they are distinctly rounded at the apex (FIGURE 23), 
while in still rarer cases they are acute and tipped with two super- 
imposed cells (FIGURE 24). This last condition, it will be re- 
membered, is the usual one in R. phyllobola.
