336 LIFE-HISTORIES OF AUSTRALIAN COLEOPTERA. 



palpi long and drooping; legs stout, long and mottled with black; 

 the inner edge of the tarsi fringed with fine white hairs; tarsal 

 claws ferruginous, the central ridge of the abdominal segments 

 marked with a line of small blackish brown spots. 



The larva attaches itself to the underside of the leaf, when the 

 larval skin splits and turns down over the pupa, remaining in 

 this position about ten days. 



This is one of the commonest ladybirds about Sydney. Both 

 beetle and larva feed upon the leaves of Solanaceous plants, 

 gnawing the epidermis off in little wavy lines, causing dead 

 patches all over the leaves. They were also very plentiful upon 

 the leaves of Datura stramonium, on the seashore at Botan}^; a 

 number that I took home were let out of the box, and a few days 

 later they were busy at work eating the leaves of the tomato 

 plants. 



It is a handsome little beetle of a deep yellow colour mottled 

 with irregular black spots; all the members of this genus, unlike 

 others of the family, are phytophagous. 



In "Insect Life," 1891, Yol. iii. Ejnlachna corrupta is stated to 

 have destroyed fully half the bean crop of New Mexico. 



An African species, E. hirta, is very destructive to potatoes 

 and tomatoes.
