After metamorphosis the young' hylas frequent any sort of situa- 
tions which will provide them with appropriate food and the moisture 
essential to protect them from desiccation. About permanent ponds 
and along the banks of streams many of the young frequent the 
lower bordering vegetation. At the season when the hylas are emerg- 
ing from the water they find in such surroundings hosts of small soft- 
bodied insects suitable for food. Considerable growth occurs in the 
summer and autumn months, as specimens measuring 20.5 to 24.5 
millimeters in head-and-body length have been taken in late August 
and early September. Indeed, slow growth probably continues 
through the winter months. An individual taken 3 miles south of 
Davis in Solano County, December 24, 1922, measures 28.2 millimeters 
in length ; several hylas taken at different localities in the State during 
April, May, and June range from 23.2 to 29 millimeters in total length. 
Animals approximating the latter dimensions have been observed
