 History of Psychopsis elegans (Gu6rin). — Proc. Linnean Soc. 

 N.S.W., Sydney, xlii, part 4, no. 172, 26th Match 1919, pp. 787- 

 818, 1 plate, 12 figs. 



The complete life-cycle of Psychopsis elegans, (liier., occupies about 

 two years. The eggs are laid in January or February in clusters 

 upon the bark of Myrtaceous trees, especially Eucalyptus. The 

 larvae hatch in about 12 days and at once hide in cracks of the bark. 

 They have 3 instars lasting 8 months, 4 or 5 months and 9 months 

 respectively. During the first instar hibernation occurs from February 

 to September, and during the third, from March to November. The 

 food of the larvae consists of the various insects that appear at night 

 to feed on the gum of the tree. In captivity they thrive best during 

 the first instar on termites and later on larvae of the codling moth 

 [Cydia pomonella]. Pupation occurs in a cocoon and lasts about 

 3 weeks, the imago emerging about December. 



If it were possible to transfer these insects to apple, pear or quince 

 orchards, they should prove a most valuable asset in the control 

 of Lepidopterous pests. Further investigations as to this possibility 

 are advised.

 company with S. culiciformis. — Entomologist, London, lii, no. 675,

Aegeria {Sesia) asiliformis is recorded in June as feeding not only 

 in the bark but also in the wood of a birch log.

A brief and popular account is given of the life-history and habits 

 of Pygaera (Phalera) bucephala, which may be found on elm, lime, 

 hazel, willow, oak, birch, beech, alder, sycamore and sometimes 

 on roses. It is easily controlled by hand-picking or spraying with 

 lead arsenate.
