longest, and the following joints as gradually shorter : 
in my specimens the third and following joints are very 
nearly equal. The thorax in all has a short transverse 
depression near the anterior margin; Chapuis, however, 
gives the thorax as convex and without depression ; it 
may be therefore that he had another species before 
him. A. smaragdipennis differs somewhat in shape, 
some specimens being shorter and more dilated pos- 
teriorly than the others. The sides of the thorax in 
most specimens are narrowly margined with flavous, as 
well as its under side; in others this colour is absent, 
but these specimens do not seem to differ in other 
respects. The species does not seem to be an un- 
common one in South Africa.

Tropidophora tripartita, Thoms., Arch. Ent., ii., 1858, 
seems identical with Physoma Dohrni, Chap. The 
species is placed in Gemminger’s Catalogue amongst 
the Galerucine, but Thomson mentions distinctly the 
‘enormously ’’ dilated posterior femora. 
Ootheca cyaneovittata, Fairm. (‘Naturaliste,’ 1880). 
This insect cannot find its place in Ootheca, if O. muta- 
bilis is looked upon as the type; it differs totally in 
general shape, in the structure of the thorax, want of 
elytral epipleuree beyond the middle, and the much 
longer first joint of the posterior tarsi.
