willows and in low situations where grasses occur if at all in 
California, but no spittle masses were ever seen, although 
careful search was made. 
Last season while collecting another rare species of 
Homoptera occurring in grassy places, the writer accidentally 
broke a leaf off from the giant Umbellifera—Heracleum lanatum 
and discovered that the enlarged sheath was full of froth and 
that nearly a dozen A phrophora larvee were hidden in the mass.

ground line. 
An examination of other sheathes revealed other froth masses 
ranging from a single larve up to over twenty in one case. 
The larve were of various sizes from one-third to full grown 
when found and a few fresh males nearby completed the 
identification. 
The weed extends across the continent from coast to coast, 
but this species of Aphrophora has only been taken along the 
California coast from Los Angeles to San Francisco. 
Like the other frog-hoppers, it appears to be single brooded, 
the larve appearing in March and April and the adults trans- 
forming from late April through May and living until into 
July and August.
