obscurely 4-jointed antennje. 1 have not had access to the 

 description of A. parrotti, Ckll., but it is unlikely that a species 

 inhabiting New Mexico will be identical with the Australian 

 insect. 



I would here like to correct a statement that occurs in one of 

 Maskell's papers (Trans. N.Z. Inst. 1898, p. 219), in which that 

 author wrongly attributes to me the opinion that his Chcelococcus 

 hambuscE is specifically identical with Antonina purpurea of 

 Signoret. Chcet. hambusce is, of course, markedly distinct. The 

 misconception arose from my suggesting to Mr. Maskell the affi- 

 nities of his genus Chcetococcus with the older genus Antonina, 

 and pointing my remarks by reference to the type, A. purimrta. 

 The lamentable death of the talented author prevented my 

 explanation of his misconception. I am still of opinion that 

 Chcetucoccus, as defined by Maskell, is inseparable from Antonina. 

 I consider the difference in the nature of the sac of his type 

 species to be merely environmental.
