5. Chelymorpha cassidea (Fabr.) is considered a composite 

 of a number of local races, four of which (lewisi Cr., phytophagica 

 Cr.l7-punctata Say and geniculata'Boh.) are indicated in the Spaeth 

 catalogue and occurs from Canada to Cuba and west to Winnipeg, 

 Washington, Utah and Arizona. As is to be expected the forms 

 differ in the extremes of their ranges, but probably no collection 

 contains representative series from enough intermediate locali- 

 ties to justify a statement of their relationship. Many food 

 plants have been named for this beetle and its larvae: milkweed 

 (Riley 1870, 2nd Rep. Nox. Ins. Mo., p. 58), wild morning-glory, 

 raspberry, cabbage, plantain and corn (Lintner 1887, Cultivator 

 and Country Gentl., vol. 52, p. 673), sweet potato, milkweed and 

 wild morning-glory (Chittenden 1897, U. S. Dept. Agri. Div. Ins., 

 Bull. 9 n. s., p. 23), strawberry vines (Webster and Mally 1898, 

 U. S. Dept. Agr. Div. Ins., Bull. 17, n. s., p. 99), Solanum (Fall 

 and Cockerell 1907, Trans. Amer. Ent. Soc., vol. 33, p. 200), 

 "Convolvulus," "Asclepias" and sometimes raspberries (Chitten- 

 den 1910 in Smith's List Insects of New Jersey, Rep. N. J. State 

 Mus. 1909, p. 356) but Mr. Knab tells me he believes that the 

 only native host-plant is wild morning-glory, and explains the 

 other records by the habit displayed by the full fed larva of mi- 

 grating to other plants for pupation. Subspecies geniculata Boh. 

 has been taken abundantly on a coarse convolvulaceous plant, 

 Ipomoea biloba, at Marathon Key and Key West, Fla., by Knab, 

 who informs me also, that the larvae differ from those of the 

 Massachusetts form. Knab 1909 (Proc. Ent. Soc. Wash., vol. 

 11, p. 152) mentions the color changes between hibernating and 

 sexually mature adults and alludes to a pale race found at 

 Winnipeg. 



6. Eurypepla jamaicensis (Linn.) was recorded by Schwarz 

 1904 (Proc. Ent. Soc. Wash., vol. 6, p. 7) as established at Key 

 West, Fla. where it lived, as Boheman has already recorded, on 

 the leaves of the "geiger tree," Cordia sebestana; and Dr. Chit- 

 tenden has just received a specimen found on the same species of 

 tree by S. H. Richmond at Cutler, Fla., July 1, 1915. E. brevi- 

 lineata Boh. from Yucatan may not be distinct from this species. 



7. Physonota alutacea Boh. is reported to range from Vene- 

 zuela to our southern boundary. Horn 1884 (Cal. Acad. Sci. (2), 

 vol. 4, p. 344) has reported var. cyrtodes Boh. from El Taste, Lower 

 Cal. and Mr. Schaeffer has taken it in July at Brownsville, Tex. 

 on Cordia boissieri and has kindly deposited an adult and two 

 larvae in the National Collection. 



8. Physonota unipunctata (Say) is variable, probably divis- 

 able into a number of more or less distinct forms which may be 

 restricted to certain food-plants, but is distributed from Montreal 

 and North Carolina to Montana and Arizona. The National
