 prosternal ])rocess very strong ; the remainder of the under surface brassy, clothed

Gold Coast. 



Callichromti rhali/beatum White {Longic. VIL 1., p. 159) is a true Mecosnsjjis, 

 and has the priority over Mecosaspis chalybeata Thorns. If the latter really 

 belongs to this genus, it has to lie renamed. 



till. Mecosaspis violacea Thorns. 

 Two specimens from (Jameroons, which 1 refer to this species, have the upper 

 side glossy black, tinged with olive green.

 the strongly rngulose elytra, its shorter shape, and its small prosternal tubercle.
