The wombat. 37 



People who are nervous and fidgetty should not be told 

 to keep still, or look pleasant, but gradually led by con- 

 versation to forget that they are under the camera's eye, or 

 allowed to become absorbed in the contemplation of some 

 book or picture, when the face will assume the appearance of 

 repose and interest suitable for the occasion. 



a catalogue of australian 

 coccid^:. 



By James Lidgett. 



The study of Coccidce is extending, and many new workers 

 are entering the field every day, so that the time has arrived 

 when a catalogue of the Australian species, embodying a 

 proper synopsis and sequence of genera and species, has been 

 thought necessary, and I venture to hope that the present 

 attempt to supply such a want may prove a noteworthy con- 

 venience. 



The very limited time at my disposal for entomological 

 work has somewhat prolonged the prosaic work of compilation ; 

 also my residence in the country, with no works of reference 

 available beyond those contained in my own private library. 

 It is therefore hoped that any shortcomings will be attributed 

 to inconvenience rather than to neglect. 



Through the kindness of Professor T. D. A. Cockerell, 

 of America, and Mr. E. Ernest Green, of Ceylon, I have been 

 able to consult many of their most valuable memoirs. Thus 

 with reference to various exotic species herein included, I 

 have followed Cockerell's synonymy, and it may here be 

 mentioned that according to that author's first " Supplement 

 to the Check List of Coccidae," up to January, 1899, it 

 appears that the number of known species has reached the 

 astonishing total of 1,119, thus showing the activity of Cocci- 

 dists. There are many species for which names have been 

 proposed and descriptions prepared, awaiting early publication. 

 I may permit myself to mention the following M.S. names — 

 Brachyscelis turbinata, Lidgett. Mytilaspis lidgetli, Ckll. and 

 Pulvinaria paradelpha, Ckll. and Lidgett. 



I have also to thank Messrs. J. G. O. Tepper, W. W. 

 Froggatt, and Henry Tryon for various species of Coccidce, 

 and for many interesting papers relating thereto. 



To M. d'Emmerey de Charmoy I am indebted for many 

 species of Mauritius Coccids, which will be referred to in 

 future papers.
