I found this species in 1895 at Sandringham on Japonica, 

 and include it and the following species chiefly to record the 

 distribution : I can find no reference to any previous record- 

 in Victoria : it is a European species.

This species also occurs at Sandringham on hot-house 

 plants, and at Brighton in the open air. It is scarcely dis- 

 tinguishable from L. hemisphcericum, and may hereafter be 

 merged into that species. 



The late W. M. Maskell identified both these insects for 

 me in 1895, and in his letter says — " The two differ chiefly in 

 size, and are both distinguishable by somewhat regular oval 

 markings on the epidermis under a lens. Neither species is 

 Australian probably."
