Myriapoda. Blaniulus gutlulatus, Gerv., caused much injury to 

 strawberries, especially in warm, wet weather. To control it, as little 

 stable manure as possible should be used in cultivation and unslaked 

 quicklime may be dug in superficially and the beds then watered.

Against the leaf-cutting ant, Atta sexdens, L., which is a serious pest 

 in Brazil, use has been made of Prenolepis fulva, Mayr, as a means of 

 controlHng it, and the breeding of this ant has been instituted on 

 commercial lines for this purpose. Dr. Costa Lima has, however, 

 pointed out that P. fulva feeds on sugary substances and protects 

 Aphids, so that other, more certain and less dangerous means of com- 

 bating A. sexdens should be employed.

Observations analagous to those on the work of Pimpla investigator 

 in parasitising many destructive larvae, including those of Cnethocampa 

 processionea and C. pinivora, have been made concerning Pimpla 

 rufata, Gm., which parasitises the larvae and pupae of Tortrix 

 viridana, L. 



During the last three years certain oak forests in western France 

 have been devastated by larvae of T. viridana: The majority of the 

 larvae from these forests were found to be parasitised mainly by 

 Ichneumons, of which the chief was P. rufata.

Kladothrips rodwayi, sp. n., is described from galls on Acacia 

 melanoxylon. These galls are similar to those made by K. nigosus, 

 both larvae and imagines inhabiting the same gall.

This paper gives some notes on Lepidopterous pests of certain 

 food-crops. Onions are attacked by Estigmene lactinea, which also 

 attacks kohl-rabi and beet, and Phytometra (Plusiu) signata. The 

 best method of control is hand-picking the caterpillars. Pests of 

 brinjals {Solanum melongena) and other Solanaceous plants are : 

 Sarrothripinae spp., which are best destroyed by crushing in situ 

 on the leaves ; these caterpillars are parasitised by a small fly which 

 usually acts as sufficient control, but sometimes appears too late
