36. Orthezia insi/jnis, Dongl. — On numerous orna- 
mental shrubs, affecting specially AcanthaceoB. Avery 
destructive species. Male slaty-grey with a brush of 
long silky filaments from extremity of abdomen. This 
species has been redescribed from Ceylon specimens 
by Mr. Buckton under the name of 0. nacrea ; but 
I can find no distinguishing points between this and 
the species from Kew. In fact our specimens are 
doubtless the direct descendants from the Kew insect, 
as they first appeared in the plant-houses of the 
Government Botanical Gardens at Paradeniya.
