Another common species is the two spotted lady- bird Cuccinella hipimdatavery similar in form and colour to the pre- vious species, but smaller and with two black spots instead of nine. The spotted lady-bird Hip2)odamia maculata fig. 10, is also frequently met with, and being found both in Europe and America has prob- ably been imported from one country to the other. The colour of this nk withlarge black spots. The thirteen spotted lady-bird Uippodamid lata fig. 11, is rather larger than either of the preceding species ind has thirteen black spots on a brick red ground. Fig. 10. The trim lady-bird Cocchiellu nmnda, Fig. 12, maybe readily]' distinguished from most of the other species by its having no black spots on its red win" cases. The convergent lady-bird Hippodamia convergens, Fig. 13, is of a deep orange red colour, marked with black and white.
