Anthonomus pomorum L. The female deposits eggs in unopened 

 flower buds and blossoms of the apple. Its injuries were recorded 

 as early as 1801, and there is now a considerable European litera- 

 ture on the species. Cold, damp weather, retarding the opening 

 of apple blossoms, is said to be quite favorable to it. The symp- 

 toms of injury are the scorched appearance of the blossoms, and 

 their failure to open normally. 



A. rubi Herbst., in Europe, injures the raspberry in about the 

 same manner as the foregoing. The weevils of the new generation 

 puncture the shoots and feed on the foliage. A. rectirostrislj. 

 attacks stone fruits in Europe, especially cherries. The grub infest 

 the pits or seeds like our Coccotorus prunicida apparently. The 

 cotton square weevil of Peru, species of Anthonomus, probably 

 vestitus Boh. injures cotton in a way similar to A. grandis. A. 

 varipes DuVal injures the egg plant in Cuba, the beetles feeding on 

 the tender buds. Magdalis is well represented in Europe by spe- 

 cies occurring on useful plants. M. armigera Geoff, infests branches 

 of plum trees. M. barbicornis Latr., the branches of apple, quince, 

 etc. M. cerasi L., cherry and plum; M. duplicate, Germ., pear; 

 M. ruficornis'Ij., various orchard trees, and M. violacea L., the 

 pear. Apion apricans Hbst., of Europe, attacks red and purple 

 clover. Eggs are placed in the blossom heads, the larvae eating 

 the unripe seeds, reducing seed production. There are several 

 broods each year. Rhynchites cceruleus DeGeer oviposits in tender 

 shoots of apple, and then cuts off the twig just below the point of 

 insertion of the egg. Considerable injury is thus done to young 

 growing trees. The insect occurs over Europe. R. ruber Fairm, 

 occurring in Greece, Corsica, Crete, etc., is a very local species, 

 but which is quite a pest of the olive. The female oviposits in the 

 fruit in which the grubs feed much like our Conotrachelus nenuphar. 

 Other species of Rhynchites are of more or less prominence in Europe 

 to one plant or another, as R. bacchus L., cupreus L., interpunctatus 

 Steph., etc. Byctiscus betulce L., distributed over Europe, Asia, 

 Siberia, etc., injures numerous plants in its range, and is especially 

 likely to attack the grape. Diaprepes abbreviatus is present gener- 

 ally throughout the West Indies, where it is destructive to sugar 

 cane, especially in parts of Barbados. Rhinaria perdix Pascoe is a 

 serious enemy of strawberry in Victoria and Tasmania, and to a 

 less extent, raspberries. Both adults and larvae are destructive, 

 though the larvae more so as they feed on the central "bud" of 

 head of the plant, thus often killing the plants outright. Rhadino- 

 somus lacordairei is said to be the worst insect enemy of straw- 

 berries in Tasmania, and occurs in all of the Australian States, and 

 perhaps in New Zealand. Another Australian pest is Leptops 

 hopei Fahrs., which is said to be one of the most troublesome 

 insects of Victoria, attacking especially apples and pears. Eggs
