Remarks. Throughout the range of chloris, the head, pronotum, and elytra are usually very distinctly microreticulate and the male sixth ab- dominal sternum is usually relatively flat and very shallowly, evenly emarginate. These two characters are of great assistance in separating chloris from stygica and comans, and the second one is very useful in separating chloris and rathvoni. However, there is sufficient variation in chloris, as well as in the other species, that these characters must be used in conjunction with others. Typical chloris, as described by Fall, seems to be confined to the Sierran foothills in Tulare and Kern counties. If we exclude for the moment two short series of specimens from Arvin and Cottonwood Creek, this population may be characterized as having the pubescence colorless, the aedeagus with a single ventral hook, and the female sixth abdominal sternum almost always entire (exceptions in two specimens from Glenn- ville and one from Lemoncove).
