imagines making their appearance at the end of the summer and

The error of treating H. oleracea, L., as a noxious species originated 

 with Linnaeus, who in Fauna Suecica Ed. II. 1761, says " Habitat in 

 oleribus frequens," a statement afterwards quoted both by De Geer 

 and Goeze, Linnaeus, however, apparently included several species 

 of flea-beetles under the name oleracea.

 Swedish Species of the Genus Haltica]. — Entom. Tidshrift, UpsaJa, 

 xl, no. 3-4, 1919, pp. 143-165, 10 figs. 



The species of Haltica that have been recorded in Sweden are : — 

 H. oleracea, L., H. lythri, Aube, and H. tamaricis, Schrank {consobrina, 

 Duft.). The species hitherto called lythri, Aube, is however identical 

 with H. brevicollis, Foudr., and H. tamaricis, Schr., does not occur in 

 Scandinavia, the specimens identified with it being found by the author 

 to be partly small specimens of H. oleracea, partly a species new to 

 Scandinavia, H. palustris, Weise, and partly H. engstromi, Sahib. 

 In addition to these the author has found H. saliceti, Weise, and a new 

 species, H. sandini. 



The food-plant of H. palustris is not yet known, but it is generally 

 found in swamjjs and marshes. H. brevicollis feeds on young hazel, 

 the imagines gnawing circular holes in the leaves and the damage 

 done by the larvae being confined to one side of the leaf. The eggs 

 are yellow and placed 4-8 together on the underside of the leaves. 

 The young larvae are at first yellow with two pairs of black spots at 

 the sides of the meso- and metathorax, but turn black after a few hours. 

 H. saliceti is found on oaks in Southern Sweden. Both the larvae 

 and the imagines skeletonise the leaves. The larvae are found on 

 oak from July to September ; when full grown, they descend to the 

 ground to pupate.

Scolytus laevis. Chap,, occurs in the smaller branches of elm trees 

 as far north as the vicinity of Stockholm. It has not been previously 

 recorded north of Denmark. 



S. loevendali, Eggerts, is not specifically distinct from S. laevis, which 

 has also been found attacking shoots of young cherry-trees in Sweden. 

 Scolytus ratzeburgi, Jans., in Dalecarlia has attacked birch trees 

 previously defoliated by ColeopJiora fuscedinella, Zell. Pityophthoriis 

 glabratus, Eich., is recorded for the first time in Sweden.

Although a number of insects and diseases of citrus trees occur in 

 Cuba, they do not often attain the dimensions of a serious infestation. 

 One of the commonest insect pests is the ant, Atta insidaris, various
