in which they construct longitudinal galleries. The eggs are laid in 

 crevices in the bark, generally in the axils of the branches. The larvae 

 hatch in 15 days and at once begin to produce small cavities which 

 they extend into the wood and prolong into galleries running upwards 

 and then outwards again to the bark. The length of the larval stage 

 is not definitely known, but in all probability the entire life-cycle is 

 completed within a year. Pupation occurs in the upper part of the 

 gallery, which u previoush'' plugged up with sawdust and larval excre- 

 ment, and the pupa is pushed halfway out of the trunk before the adult 

 makes its escape.

Heliothis {CJiloridea) ohsolela is recorded as infesting pea-pods 

 {Pisum sativum) ; this is the first time this moth has been reported 

 from the south of Chile. 



Apanteles riverae. Porter, previously described as a parasite of 

 Orgyia (Notolophis) antiqua, is now recorded as parasitic upon the 

 larvae of the Sphingid, ProtojMrce sexta caestri.

Among the 63 species of Scolytids recorded in this list is Myelophilus 

 piniperda, L., var. pallidus, nov., which is distinguished as a 

 sub-species largely on its uniform yellow colour. It has been taken 

 on Pinus halepensis in Cuenca and other localities in Spain.

Referring to the variety recorded in the preceding paper, the author 

 points out that observation of this beetle in Murcia and elsewhere, 

 where it occurs on Pinus halepensis, shows that yellow-coloured 

 individuals are always found under the bark while those captured 

 in the buds after hibernating and shortly before reproduction, as well 

 as in the egg-galleries, always exhibit the dark coloration of the adult 

 stage. The same observation applies to individuals taken on Pinus 

 pinaster in Asturias. It is not considered therefore that the character- 

 istic of the yellow colouring upon which the new variety is chiefly 

 based is sufficient to justify its establishment.
