R. C. Griffith, Esq., in the Chair. 
Mr. Westwood read his paper entitled ‘‘ Descriptions of some Co- 
leopterous Insects from Tropical Africa belonging to the Section 
Heteromera.” 
The insects comprised in this paper are of extreme rarity, and are 
the giants of the family Tenebrionida, constituting the genus Chi- 
roscelis and other allied groups; some of them, however, appear to 
lead to Lagria in their metallic colouring, &c.
