Ftjrther Coccid Notes : with Description of New Species, and Discussion of 

 Points of Interest : by W. M. Maskeli, Eegistrav of the University of New 

 Zealand ; Corr. Mem. Eoy. Soc. of South Australia. Trans. New Zealand Institute, 

 1897, pp. 219—232, five plates. 



The majority of the new species recorded in this paper form part of a collection 

 of Coccidce made by Mr. A. Koebele, in China and Japan, in 1896 and 1897, and an 

 advance list of all these briefly mentioned therein was published in this Magazine 

 in October, 1897 (vol. viii, 2nd ser., p. 239). 



Besides this matter, three pages are occupied with a critical notice of two pub- 

 lications which appeared in 1897, dealing with the genus Jspidiotus, both proposing 

 to divide it into a number of sub-genera. One is merely a preliminary synoptical 

 tey, without detailed descriptions, by Dr. G. Leonardi, of the Laboratory of 

 Economic Entomology at Portici, Italy. This suggests nine sub-genera, all founded 

 upon the anatomical features of the female insect, without taking any notice of the 

 puparium ; but, says Mr. Maskell, " unless Dr. Leonardi proposes to give much 

 fuller details when defining completely his sub-genera, I think that some of his 

 characters are scarcely valid." 



Of Mr. Cockerell's work, of which the great industry and acumen are willingly 

 acknowledged, Mr. Maskell says that " the general question of generic subdivision 

 seems to be entirely premature. In my opinion it will be none too late twenty years 

 hence to begin the work. The total number of species of all the genera of Coccidee 

 now known to science does not esceed one thousand, and it is absurd to imagine that 

 we have discovered more than a fraction of those existing in the world. It results, as 

 a matter of course, that any scheme of subdivision of so small a genus of insects as 

 Aspi'diotus xanat be continually subject to revision, to re-revision, to revision a fourth 

 or a tenth time, as new forms are found to obliterate the boundaries laid down by 

 this or by that author. There is not the least cause for hurry. If all the species 

 now known are left in Aspidiotus no harm can be done, whereas if all the suggested 

 sub-genera have to be again divided, split into minute fragments, shifted about to 

 suit the needs of the day, the future student must be subjected to confusion and 

 trouble quite annoying and wearisome." These words will be thoroughly endorsed 

 by all students. 



It is very sad to know that these " Notes " are the last by their author, and that 

 Cocci(?-students all the world over have been deprived by death of a friend and 

 guide through the intricacies inherent in their subject. — J. W. D.

 Hemiptera, commences with a history of the study of this Order in Hungary.
