11. Aulacophora quadrimaculata Fabricius. 



Crioceris quadrimaculata Fabricius, Sp. Ins., i, p. 152, 1781. 



Fabricius described this species in the work cited above from two speci- 

 mens in the Banksian Collection, which is preserved in the British Museum 

 (Natural History). The specimens in question are stated by Fabricius to have 

 been obtained by Dr. Forster at the Cape of Good Hope, which is probably incor- 

 rect ; but the statement at least shows that the insects were collected in a 

 distant foreign land, and not in Europe. In Ent. Syst., i (2), p. 12, 1792, Fabricius 

 bestowed the name Crioceris quadrimaculata upon a second species, stated to 

 have been found in Southern Germany. This latter species, the type of which 

 is in the Lund Collection, in all probability is in no way related to the Crioceris 

 quadrimaculata in the Banks Collection. At any rate, whatever may be the 

 insect in the Lund Collection, the name given to it is not valid and need not 

 concern us here. 



Among those beetles occurring in Oceania and the adjacent regions with 

 the type of pattern consisting of two large black patches on each elytron, one 

 of the means by which species may be differentiated is afforded by a secondary
