E. P. CHASE, 
Los Angeles, California. 
Aaolla aiicnloides Lam. — This tiny pteridophyte is growing abun- 
dantly in the Los Angeles River between North Main Street and 
North Broadway. Not only is it growing in the water, but also at 
the water's edge, in the sand, there are many rounded tufts two to 
three or more inches in diameter and nearly an inch in height, much 
as some mosses grow in eastern and northern woods. — G. L. M. 
Ctenucha hrunnea Stretch. — Emmet Meek found this pretty blue 
moth swarming by the thousands around a yellow composite shrub in 
the Los Angeles River bottom, near Elysian Park, in September, 1916, 
and later in the same month with the writer, they were found still as 
abundant, and many were captured in good condition. Although they 
seem to be somewhat sluggish in behavior, they are wary and are not 
so very easy to net. This is the first time this insect has been noticed 
in such numbers. It is not common in collections.
