Caterpillars reported as defoliating tomato plants m the State of 

 S. Paulo have been identified as those of the Danaid butterfly, Mechanites 

 nessaea lysimnia, F., which are known pests of Solanaceae. Spraying 

 with Paris green or lead arsenate is advised, the latter being preferable 

 as it is less liable to scorch the foliage. From f to lib. of lead arsenate 

 per 18 gals, water is a suitable strength. The first application should 

 be made when the caterpillars are quite small, but if the infestation is 

 not severe, the cheapest and best remedy is hand-collection. 



A Cercopid, Tomaspis parana, has been causing serious injury to 

 sugar-cane in the State of Minas Geraes. The mfested canes should be 

 cut down and burned in the field, a hot, sunny day being chosen so as 

 to ensure the destruction of the larvae in the ground.

There does not appear to be any previous mention of the occurrence 

 of Syrphid larvae in conifers, especially in the mines of Hylobius larvae. 

 From larval mines in trap-billets infested with Hylobius abietis a 

 number of Syrphid maggots were taken in the Upper Palatinate. They 

 closely resemble those of Brachyopa, Meig., BaccJia, F., and Neoascia, 

 Willist., but a complete identification was not possible. An illustrated 

 description of these larvae is given.

An infestation of coff eeberry clusters with the scales, Coccus {Lecanium) 

 viridis and Pseudococcus sp., caused the green berries to fall. Although 

 spraying the clusters with a 5 per cent, soap solution proved effective 

 the cost is so high as to be unjustified by the limited injury done. 

 Infestation by Xyleborus coffeae resulted in a withering of coffee twigs. 

 An increased spread of Stephanoderes hampel was noted ; some coffee 

 samples, believed to be attacked by this beetle, were found to harbour 

 the Anthribid, Araecerus fasciculatus. Extended observations
