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

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

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

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

 {TiUa americana), is the favorite food tree. Larvae 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 (Prunus virginiana) 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 "Web.). 



According to published statements the beetle 

 makes its appearance during the latter part of 

 May, and soon afterwards deposits its eggs on the 

 leaves of the trees which form its larval food 

 plants. 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 history of this insect 

 appears to resemble very closely that of the leaf- 

 mining locust beetle. Fortunately it seldom oc- 

 curs in abundance 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 

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

 to be unique. 



Concerning this species Mr. William Beutenmuller writes in 1890 

 that it ••mines the leaves of apple and linden." The perfect insect may 

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

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



Odontota nervosa Panz. 



This common little species, which has also received rather frequent 

 mention under its two synonyms, inaequalis Web. and rosea Web., is
