parenchyma of a leaf of white oak, A description of the larva is 

 given, with biologic notes (1. c). Since that time this species (lig. 4) 

 has been found to attack numerous other plants, and the writer has 

 already expressed the opinion that the foliage of linden, or basswood 

 {Tilia americana)^ is the favorite food tree. Larvee and adults, the 

 former mining the leaves and the latter feeding on the lower surface 

 of the same, can be found in abundance at Ithaca and elsewhere in 

 New York during the month of June, the imago occurring as, late as 

 September (Proc. Ent. Soc, Wash,, Vol. II, pp, 266, 267). 



Among other food plants are English filbert and orange, the imago 

 having been found occasionally attacking the leaves of the last men- 

 tioned plant in Florida by the late H. G. Hubbard. It is more par- 

 ticularly, however, as an enemy to apple that this species has received 

 mention by Harris (Ins, Inj. to Veg., 1863 ed,, pp, 120, 121), 

 Chokecherry {Priotus vmjiniana) is also recorded as the food plant 

 ,}^ by Harris, as also the shadbush or service berry 



{Amelanchier canadensis). 



It has been called the rosy Hispa, from one of 

 the Latin names {Hispa rosea y^€^.). 



According to publifshed statements the beetle 

 makes its appearance during the latter part of 

 May, and soon afterwards deposits its eggs on the 

 leaves of the trees Avhich form its larval food 

 phmts. The eggs are described as small, round, 

 and of a blackish color, fastened to the surface of 

 the leaf either singly or in groups of four or five. 

 In most respects the life histor}'^ of this insect 

 appear.s to resemble very closely that of the leaf- 

 mining locust beetle. Fortunately it seldom oc- 

 curs in abundaiu-e and has not often been re- 

 ported, to the writer's knowledge, as having been 

 the source of any considerable trouble. The experience of Mr. W. L, 

 Devereaux at Clyde, N, Y,, cited in the Fifth Report of the United 

 States Entomological Commission (p, 480), that this insect is a very 

 conspicuous pest in that vicinity, "" destroying the entire foliage of 

 ever}" basswood in many forests except trees of great height," appears 

 to be unique. 



Concerning this species Mr, William Bcutenmuller writes in 1890 

 that it "'nunes the leaves of api)le and linden." The perfect insect may 

 also be found on white birch, horn bean, cherry, Juneberry (Amelan- 

 chier), and Pyrus arhati folia (Entom. Amer., Vol. VI, p. 178).
