a related species (olivieri) is considered the worst leaf-eating pest 

 with which gardners have to deal, attacking also the fruit of the 

 cherry. Another species, A. foveicollis Kuest. is a cucurbit pest 

 of importance in Formosa, India, etc. and, A. exacavata Baly is 

 present along with the former, and has about the same habits. 



RHYNCHOPHORA. 



Among the Rhynchophora are to be listed very many of the 

 worst insect pests of the world, and the number of species to be 

 noted in the present connection is relatively large. 



AnthribidcB. 



The apple beetle of Australia, Doticus pestilens Oliff, falls here. 

 It is supposed that eggs are laid in the young fruit. The grubs 

 live in the apples, which, after about a month, shrivel and dry and 

 remain hanging on the trees. The stages of the insect are passed 

 in the fruit, the beetles coming out in the spring, ovipositing in the 

 young fruit. 



Curculionidce. 



Several species of Otiorrhynchus are to be mentioned. 0. sul- 

 catus F., native to northern and middle Europe, is now present in 

 New Zealand, Australia and South Africa. It injures both the 

 roots and foliage of strawberry and raspberry plants. 0. corruptor 

 Host occurs in Italy and attacks the foliage of the grape and almond. 

 0. singularis L. is a pest of raspberries in Europe. The beetles 

 eat the fruit buds, blossoms and foliage and gnaw the bark of 

 tender shoots. The grubs feed on the roots of the raspberry and 

 various other plants. 0. Icevigatus Fabr., occurring over middle 

 Europe, is injurious to buds and shoots of plum, and 0. ligustici L. 

 in central and southern Europe, attacks grape, peach and hops, 

 etc., injuring the leaf and fruit buds, as well as the shoots. Several 

 other injurious forms in the genus ought to be mentioned. Pach- 

 neus litus and P. azurescens are serious orange pests in Cuba, the 

 larvae feeding on the roots of the plants. Phyttobius maculi- 

 cornis Germ., P. oblongus L., P. pyri L., occurring over Europe, 

 attack various fruit trees, as well as Fagus, Quercus, etc. Banj- 

 pithes araneiformis Schrank, present in central Europe, injures 

 strawberry by eating holes in the green and ripe fruit. Sitona 

 lineata L., distributed over Europe, and S. sulcifrons Thunb, 

 attack the shoots of peas as they are pushing through the ground, 

 and later, the foliage. Cleonus luigionii Motsch. present in central 

 and southern Italy, is quite injurious to the beet, the larvae boring 

 the roots. Liparus coronatus Geoze, is destructive to carrots in a 

 similar way. Phytonomus variabilis Herbst. attacks species of
