ASI'IDIOTUS HEDEILE. 123 



Exuviae central or approximately so ; are usually naked, 

 and vary from pale to bright orange yellow. 



Perfect male pale yellow mottled with dull purplish 

 brown, or reddish brown ; apodema brighter. 



Eggs and larvae pale yellow. 



Habitat. Under glass ; occurring throughout the 

 British Isles as a common greenhouse pest, infesting 

 many kinds of plants. The following is a list of the 

 principal food-plants : Various species of palms, 

 Agave, spp., Ulrica, spp., Passiftora, spp., Tacsonia, 

 sp., Dracaena, sp., Aucuba, sp., Azalea, sp., Aristea 

 major, Lardizabala, sp. 



Distribution. It is found abundantly in the open 

 air in the South of Europe, North Africa, United States 

 of America, Australia, and New Zealand ; is apparently 

 Cosmopolitan and almost omnivorous. 



This species is given to a great amount of variation 

 in the colour, texture, and substance of the puparium, 

 which in a great measure, no doubt, accounts for the 

 long list of synonyms. Specimens from Aloe received 

 from various countries have very dense puparia, and, 

 although at first pure white, eventually become dull 

 opaque straw colour. Again, the examples on imported 

 lemons have the puparium very thin and flat, much 

 more so than the examples on Aloes, and are invariably 

 accompanied by a green discoloration of the fruit (PL 

 VIII, fig. 6). Specimens on palms in this country are 

 also thin and semi-transparent, of a pale straw colour, 

 and never opaque snow-white, as in typical examples. 



The synonymy of the species is taken chiefly from 

 Dr. Leonardos excellent monograph, which is here 

 gratefully acknowledged.
