 xii, no. 3, September 1921, pp. 567-621, 46 figs. [Received 2nd 

 February 1922.] 



In this instalment of his monograph on African termites [R.A.E., 

 A, ix, 521] the author discusses the food of termites and the foraging 

 expeditions of Hodotermes. The construction of the nest of H. trans- 

 vaalensis is described, and short notes are given on other species of 

 Hodotermes and Psammotermes. The leaf-cutting species are dealt 

 with, and one section describes the construction of the fungus gardens 

 that are characteristic of certain species. 



La Maladie des Cafeiers due au Stephanoderes coffeae, Haged. — Bull. 

 Agric. Congo Beige, Brussels, xii, no. 3, September 1921, pp. 624- 

 625. [Received 2nd February 1922.] 



Coffee plantations in Java and Sumatra are reported to be infested 

 by the Scolytid, Stephanoderes hampei, Ferr. [coffeae, Haged.), which 

 has evidently been imported with seed from the Congo. An account 

 of this beetle, with recommendations for avoiding infestation, is re- 

 capitulated from an earlier paper [R.A.E., A, iii, 649], and reports 

 from Java on the subject of this pest are quoted \cf. R.A.E., A, 

 viii, 447-9]. 



In infested plantations, all infested berries should be gathered and 

 thrown into a 5 per cent, creolin solution. Upon arrival at the mills 

 the creolin solution should be poured off and the berries dropped 

 into boiling water for 15 minutes, after which they are dried. By 

 this method all odour of creolin is removed. The collection of infested 

 berries should be carried out each month, all the black berries being 

 gathered as well as the green infested ones. The most severely infested 

 fields should receive a second examination, and watch should be kept 

 over these vmtil the general coffee harvest begins. 



Mayne (R.). Un Inseete nuisible aux Noix Palmistes, centre lequel

There are two insects occurring in the Belgian Congo that are 

 seriously injurious to Elaeis guineensis (oil palm). The most dangerous 

 of these is the weevil, Rhyncophorus phoenicis, the larvae of which 

 attack the heart of the palm, causing decay and eventually death. 

 The other is Oryctes monoceros, and, in certain regions, the allied 

 species, 0. boas. The adults of Oryctes mine the petioles of the leaves, 

 the galleries sometimes reaching to the heart of the plant and causing 

 its death.

In the province of Jaen the fumigation campaign against Phloeo- 

 thrips oleae was continued. In Saragossa the sugar-beet crop was 

 severely attacked by Euxoa ( Agroiis) segetum.
