F. Heikertinger deals with the leaf-mines of the flea-beetle, Phyllotreta 

 nemorum, L., infesting cruciferous plants. Other authors have described 

 them as serpentine in shape whereas actually they are roundish, 

 irregular spots or flat blisters. 



J. Bachinger points out that hitherto only rosaceous plants have 

 been recorded as food-plants of AntJwnomiis rubi, but the Compositae 

 must now be included, as he has found this weevil in the flowers of 

 Tragopogon pratensis and Buphthalmum salicifolium, and these flowers 

 were accepted as food by captive specimens. The same author has 

 found Centhorrhynchus puncticollis feeding on the leaves of Erysiimun 

 canescens. In a footnote, H. Scheuch points out that a similar record 

 was made by Ganglbauer in 1882 and that he himself has found it on 

 E. canescens and E. hieracifolium . 



With reference to the food-plants of Ceiithorrhynchus pulvinatns, 

 Gyll., H. Scheuch gives the following list : Sisymbrium sp., S. sophia, 

 Erysimum cuspidatum, Rapistrum perenne, Bertoroa incana and 

 Camelina sativa. Both Cirsium arvense and Matricaria chamomilla 

 appear to have been recorded in error in the literature. C. pulvinatus 

 is a typical feeder on Cruciferae, to which plants the closely-allied 

 species, C. pyrrJiorhynchus, Marsh., is also exclusively confined. 



F. Heikertinger records Baris gudenusi from the Cruciferae, 

 Rapistrum perenne and Sisymbrium, striciissimum ; on the latter plant 

 it occurred together with Phyllotreta austriaca.

This is a resume of the reports for the first quarter of 1919 sent in 

 by the agents of the Anti-Bollworm Service in Brazil. In one locality 

 in the State of Maranhao a loss of 70 per cent, was caused by Platyedra 

 (Gelechia) gossypiella. Carbon bisulphide and hot water are mentioned 

 in the report from the State of Piauhy as being used for seed disinfection. 

 In this State Alabama argillacea and a weevil, Gasterocercodes gossypii, 

 Pierce [R.A.E., A, iii, 273], also injure cotton.

The State of Pernambuco, which produces most of the Brazihan 

 sugar, has suffered more losses from sugar-cane beetles than the 

 adjoining ones of Alagoas and Parahyba, where they also occur. In 

 view of the need for methodical application of remedial measures 

 the author was commissioned to study these pests. 



The species concerned- are two Scarabaeids native to Brazil, Ligyrus 

 fossator, Dej., and Podalgus humilis, Burm. The former also occurs 

 in French Guiana and the latter, in French Guiana, Colombia, Panama 

 and Mexico. They are subterranean species and when, as the result of 

 bringing virgin land under cultivation, the soil moisture conditions are 

 modified, both the beetles and their larvae seek out the damper places. 

 For this reason they are most abundant in flat districts where there are
