1 1 8 Chionaspis. 



Habitat on the bark of the small branches and twigs of Musscenda 

 frondosa; occasionally upon Loranthus and Debregcesia. Pundaluoya. 



A much larger and more robust species than aspidistrce^ from which it may 

 be distinguished by the larger and more prominent median lobes, and by the 

 relative positions of the anal and genital orifices. The second pellicle also 

 affords useful specific characters, that of musscendce having large and prominent 

 median lobes at the posterior extremity, the same parts in aspidistrce being 

 minute and sunk into the margin (compare Plates XXXV., fig. 13, and XXXII,, 

 fig. 17). The unusual erect position of the male puparia is characteristic of the 

 species. 



The female insect is very frequently parasitised by the minute hymenopteron, 

 Aphelinus diaspidis^ How.
