nests in which they Hved. The larvae hibernate and are largely 

 parasitised by a Tachinid and by the Braconids, Apanteles glomeratus 

 and A. spur ins. 



Apricot trees in the Rhone valley have been killed in many cases 

 by Scolytus rugidosus, while peaches have suffered from the attacks 

 of Neurotoma nemoralis. Against the former, various formulae for 

 sticky washes and sprays were tried without success ; it is considered 

 the best plan to cut down in spring all branches that show wilted leaves 

 and burn them at once. This is not difficult, as the infestation is 

 never widespread. Cherry trees were also sometimes attacked, but 

 peaches were never affected. 



Pyrausta nuhilalis, Hb. (European corn-borer) has done considerable 

 damage to maize in the south-west of France. It was noticed that 

 many of the galleries had been opened by birds and the larvae extracted. 

 From 15 larvae examined, two Ichneumonids [Limneria alhida) were 

 obtained, and four Tachinids [Paraphorocera senilis and Zenillia 

 roseanae) .

The first section of this paper deals with the species of Haplothrips 

 from Ceylon and Dutch East Indies, including H. ceylonicus, Schmutz, 

 var. vernoniae, nov., from leaves of Vernonia cinerea, and H. inquilinus, 

 sp. n., from leaf -galls on Ficus henjamina and Smilax sp., and a key 

 is given to the species concerned. In the second part there is a key 

 to the European species, with descriptions of several of them. The 

 third portion describes two new genera from Java, Trichaplothrips 

 and Glenothrips.

Full descriptions are given of a number of species from the Mjoberg 

 expedition, of which only brief notices have been published.

This paper includes descriptions of Agnostochthona curvidens, sp. n., 

 and M achatothrips heveae, sp. n., on Hevea. The new species from tea 

 are Bregmatothrips theifloris, which lives in the blossoms and may 

 be useful as a pollen carrier ; and Anaphothrips theiperdus, A. theivorus 

 and A. theifolii, which cause a longitudinal rolling of the leaf, in 

 which Haplothrips inquinatus, sp. n., is a tenant. A. theifolii seems to 

 be the least harmful of the three. The only measure consists in 

 plucking and burning the infested leaves.
