Coast, however, where the climate is more similar to the eastern United 

 States, it was not causing any damage. Therefore, it may be best 

 adapted to drier regions, and consequently might not do well if intro- 

 duced into many parts of eastern North America.

Intermediate Population. — Intennediates between M. constridum constrictum 

 and M. constrictum austrinwn. All of the following localities are in Los Angeles 

 Co., but similar populations will probably be found both east and west of 

 these localities: Angeles Crest Highway; Bouquet Canyon; Charlton Flats; 

 Crystal Lake, San Gabriel Canyon; San Dimas; San Gabriel Canyon; Sierra 

 Madre; Tanbark Flat; Tujunga. In fact, some of the adults from San Ber- 

 nardino Co. which were arbitrarily classified as M. constrictum constrictum 

 because they were predominantly yellow may be from populations having 

 intermediate lai'val characteristics.
