porated. Mr. Marsh found the larvae attacking lima beans at Santa 

 Ana, Garden Grove, Anaheim, and Watts, in California. At Garden 

 Grove they had destroyed 40 per cent of the crop. 



SYNONYMY AND DISTRIBUTION. 



The species Etiella zinckenella was described by Treitschke x in 

 1832, and the variety E. zinckenella schisticolor was described as 

 E. schisticolor in 1881 by P. C. Zeller 2 from two specimens, a male 

 and a female, collected from "very different parts of North America.'' 

 The male was from California and was collected October 8, but of 

 the female he has nothing to say. He also refers to specimens of 

 E. zinckenella examined by him from Sierra Leone, West Africa; 

 Madagascar; Honda, Colombia, South America; and "Carolina "in 

 this country. Later Rev. G. D. Hulst 3 redescribed this species 

 under the name Etiella villosa, and gave Colorado and Calif orina as 

 the habitat. Dr. H. G. Dyar in his catalogue gives Arizona as an 

 addition to the habitat. 



The typical E. zinckenella is represented in the National Museum 

 collection by specimens from Hampton, N. H.; Weekapong, R. I.; 

 Key West and Archer, Fla. ; Oxbow, Saskatchewan; Texas; Still- 

 water, Okla.; and Denver, Colo. The variety E. zinckenella schisti- 

 color is represented by specimens from Stockton, Utah; Springfield, 

 Idaho; Eldorado, Clairmont, Alamecla, and San Diego, Cal.; Nogales, 

 Ariz.; and Pullman, Wash. It will be noted that all the specimens 

 of the variety were collected west of or in the Rocky Mountains. 



Etiella zinckenella schisticolor differs very slightly from the typical 

 form. It has a suffusion of gray scales on the primaries as its chief 

 distinctive character. A number of specimens from Florida, one 

 specimen from Rhode Island, and one from New Hampshire very 

 closely resemble the European specimens of E. zinckenella. 



A possible explanation of the above facts may be that the variety 

 schisticolor is a native of the Pacific slope of this continent, while the 

 forms found in the eastern United States are the typical E. zincken- 

 ella recently introduced into this country from the Old World or South 



America. 



FOOD PLANTS. x 



Larvae of Etiella zinckenella have been recorded a,s feeding on the 

 seed of several species of leguminous plants. In California (Eldorado 

 County) Mr. A. Koebele 4 found them doing considerable damage 

 to lima beans and they were recently found by Mr. H. O. Marsh, 5 

 of this bureau, working on the same crop in that State. Mr. E. E.
