Orgyia (Notolophus) antiqua is recorded as doing considerable damage 



to the leaves and young fruit of apples. The Ptinid beetle, Calym- 



moderus capucinus, Sol., is recorded in oak furniture, the wood being 



perforated with its galleries.

The caterpillars of the Lasiocampid moth, Macromphalia dedecora, 

 are abundant on cypresses, casuarinas and pimento in the public parks 

 of Santiago, and in smaller numbers on other garden and orchard 

 plants, such as lilies and damsons, and if it were not for certain parasitic 

 enemies, would undoubtedly become a serious pest. 



The parasites that limit the abundance of M. dedecora include the 

 Ichneumonid, Cnjptns horsti, Brethes, which is a formidable enemy of 

 the larvae. Another larval parasite here described is Apanteles 

 macromphaliae, sp .n. This is an even mora important parasite than 

 C. horsti, and has two generations a year ; the first appears about 

 the end of April, issuing from larvae of M. dedecora, and the second 

 emerges about the end of October from cocoons of M. dedecora and 

 parasitises the larvae of Dirphia amphimone, being thus enabled 

 to survive until the spring, when it can again attack M. dedecora. 



Parasites of the eggs of M. dedecora include the Chalcidids, Calosoter 

 silvai, Brethes, Aprostocerus worax, Wlk., and Dirjjhiphagus a«ci7/a,"Wlk.

Investigations are being made on Trioza alacris, F., which was 



observed in February in the town of Buenos Aires on laurel {Lauriis 



nohilis), this being apparently its only food-plant. _ The life-history of 



the insect has not yet been worked out, but descriptions are given of 



the various stages to assist in its identification. The larvae and 



nymphs make numerous punctures in the laurel leaves and cause them 



to curl and turn yellow, the insects sheltering in the curled leaves 



under a sticky, wax-like secretion. The larvae of a Dipteron, probably 



a Syrphid, have been observed in company with the early stages of 



T. alacris.

The caterpillars of this Cossid moth are recorded as tunnelling in 



willows in La Plata. They infest -the trunks and main branches.
