264 ENTOMOLOGICAL SOCIETY 



May and June, eating the fresh young leaves of another legumin 

 ous plant, the hog pea-nut (Amphicarp&a monoica). Although 

 occasional stragglers are found on other wild plants, this 

 species appears to be somewhat restricted to the lyeguminosae. 

 It occurs at about the same time as Anomcza laticlavia. 



The only published records that I have been able to find of 

 this beetle are those of Mr. F. M. Webster, in the Report of 

 the U. S. Department of Agriculture for 1887 (p. 152), who 

 found it destructive to beans and cow-peas in Louisiana and to 

 beans in Indiana, and of Mr. E. A. Popenoe, in the Second 

 Annual Report of the Experiment Station of the Kansas State 

 Agricultural College, for 1889, who found it injurious to the 

 bean in Kansas, and from the nature of its known food plant, 

 designated it by the name of bean leaf-beetle. It was first 

 reported by him as occurring on the bean in the Transactions 

 of the Kansas Academy of Science for 1876. 



In finding the insect in such abundance on bush-clover I 

 believe that we have discovered a natural and favorite food 

 plant, as there is scarcely a doubt that the larvae also subsist 

 in some manner on this plant. 



Luperus meraca Say. During one season I observed this 

 species in great numbers at Ithaca, from the middle of June 

 until later, eating the leaves of witch-hazel (Hamamelis vir- 

 ginica), which appears to be a natural food plant. In some 

 places it had developed a most extraordinary taste for the 

 petals of the wild rose, and as an instance of their abundance, 

 I have recorded in my collecting notes, having taken upwards 

 of a dozen specimens from a single blossom, and even detected 

 them gnawing the buds. In other localities the roses were 

 entirely free from attack. It ate also the leaves of blackberry, 

 raspberry, chestnut and other plants. The occurrence of the 

 insect in such numbers during this single year was exceptional 

 as the beetle is comparatively rare, for a Chrysomelid, in most 

 localities that I have visited. 



Galeruca tuberculata Say, was found in numbers on low wil 

 lows (Salix spp.) during the first part of July. In the larval 

 state they doubtless live also on willow leaves, as I found at the 

 same time with the imagos what I took to be the larvae of this 

 species. It might be worth recording that this species was 

 only found in one year in a very restricted locality, and on a 

 single clump of trees, not a single specimen being taken at any 

 other time. From the close relationship of this insect to its 

 congener, G^. decora Say, it will probably be found to have 

 nearly identical habits. The latter has been found a serious 

 enemy to the leaves of willows by Professor Riley, who men 

 tions it in his Annual Report for 1884.
