Mr. Walker, from whom the preceding descriptions of species of Acri- 

 dium have been copied, remarks that the last species, like Cyrt. munda, repre- 

 sents a transition from the Acrldlum ty|ie to the Caloptenus type. The 

 anterior vertex is between a hexagonal and an elliptical form, and the upper 

 part of the front is not excavated.
