The ground-color is a lighter yellow than that of E. borealis. It is desirable to find if this species does not feed upon some other food plants than those of E. borealis. This species is named in honor of Prof. W. L. Tower, of the University of Chicago, whose experimental work upon the genus is awaited with great interest. Epilachna corrupta Mulsant.

This species is named in honor of Prof. W. L. Tower, of the University of Chicago, whose experimental work upon the genus is awaited with great interest. Epilachna corrupta Mulsant. Distribution: Arizona, Mexico, and New Mexico. Typical pattern: Spots 1 and 4 are free from the suture and in place of a large single apical spot are 2 smaller ones placed well apart transversely. Form A. Mesal and intermediate spots of the inter- mediate row narrowly confluent; 1 specimen and some intergrades. Var. juncta, n. var. The two apical spots confluent; 1 specimen. The food plant is the bean. The larvae refused to eat cucurbit leaves of several species. They were successfully reared, however, on bean leaves at Cold Spring Harbor. The imagoes showed no modification there in the direction of the pattern of E. borealis; in fact, a few showed a slight decrease in the amount of pigment. The attempt to hybridize them with E. borealis was unsuccessful. Epilachna mexicana Guerin. Distribution: Mexico and adjoining parts of the United States. This species shows a reversed pattern, light spots upon a dark ground. Living specimens could not be obtained nor enough dead ones to make a study of the variation.
