 The above named insect was described by Professor Westwood 

 from the collection of the Rev. F. W. Hope, who obtained it from 

 that of M. Gory, with the habitat of New Holland. If the speci- 

 rnen I lately inspected in the Hopeian Museum at Oxford is the 

 insect in question, and I have but little doubt of its being the 

 original type, it must be quite evident that some confusion has 

 arisen with reference to the locality, as 1 believe it to be iden- 

 tical with ^gus cicatrosus 2 , of Wiedemann, a not uncommon 

 insect from Java, which is the female of JEgus acuminatus of 

 Fabricius.
