120 PROCEEDINGS ENTOMOLOGICAL SOCIETY 



Collection contains, among other specimens, a series of a small 

 form from Pine Ridge, Nebr. received from Prof. Bruner as feed- 

 ing on Monarda, and two specimens of a large form, doubtfully 

 belonging to this species, taken on Gaertneria xanthocarpa in the 

 Santa Catalina Mts., Ariz, by Pierce. A specimen labelled 

 Tucson, Ariz., sent me under the name picticollis Boh. by Mr. 

 Schaeffer differs slightly in form from the two latter specimens 

 although it is undoubtedly the same species, but all differ in 

 habitus from a Guatemalan specimen of picticollis received from 

 the Biologia collection. Popenoe 1877 (Trans. Kans. Acad. Sci., 

 vol. 5, p. 36) records it on Vernonia while Walsh and Riley 1879 

 (Amer. Ent., vol. 2, p. 4) state that its larvae feed on Sonchus. 

 Hamilton 1884 (Can. Ent., vol. 16, pp. 134-5) reports a form 

 breeding on a mint Monarda fistulosa, at Allegheny, Pa. (which 

 seems to be different from the Pine Ridge form on Monarda) 

 and cities Randall's and Walsh and Riley's forms as breeding on 

 Helianthus. Caulfield 1884, 1886 and 1887 (Can. Ent., vol. 16, 

 p. 227; vol. 18, pp. 40-45; and vol. 19, pp. 73-76) gives three 

 accounts of a form on Helianthus decapetalus near Montreal, and 

 Hamilton 1886 (Can. Ent., vol. 18, p. 113) insists on the distinct- 

 ness of unipunctata and 5-punctata. Knab 1909 (Proc. Ent. Soc. 

 Wash., vol. 11, p. 151) reviews Caulfield's notes in regard to 

 nuptial colors. 



9. Cassida nebulosa. This European species is said to be de- 

 structive to cultivated beets and if the three records cited below 

 are correct, it is strange that it has not received more attention 

 in our literature. Horn 1894 (Ent. News, vol. 5, p. 146) records 

 its capture by Bolter near the Santa Ana River in Southern 

 California and Schaeffer 1901 and 1902 (Proc. X. Y. Ent. Soc., 

 vol. 9, p. 94, and vol. 10, p. 170) mentions its occurrence at 

 Suffern, N. Y. 1 



10. Cassida rubiginosa Mull. The extensive synonymy in 

 this genus has made recognition of forms by name very uncertain 

 and our records of the capture of this species in America are mostly 

 under the specific names viridis and thoracica. Three citations to 

 its occurrence on burdock at Levis, Quebec are as follows: Fyles 

 1902 (Can. Ent,, vol. 34, pp. 273-4), Roy 1902 (Nat, Can., vol. 

 29, pp. 145-149, figs. 1-6) and Fyles 1903 (Nat, Can., vol. 30, 

 p. 22). Schaeffer 1903 and 1904 (Journ. N. Y. Ent, Soc., vol. 

 11, p. 113; vol. 12, p. 60 and p. 258) has mentioned the species 

 on three occasions, on the last of which he gave the above name 

 for the insect on the authority of Weise. 



1 These latter notes may, however, have been based upon the specimen 

 herein mentioned under the name Cassida flaveola.
