 SUBFAMILY ASTEROLECANIINAE

INTRODUCTION 



This paper presents the third completed set of results derived 

 from the study of the collection of scale insects accumulated by Mr. 

 W. M. Maskell of New Zealand during the years 1869 to 1897.^ 



The species considered here are those from the Maskell collection 

 which are definitely assignable to some one of the genera now in- 

 cluded in that section of the old subfamily Dactylopiinae which is 

 currently designated as the subfamily Asterolecaniinae. As in pre- 

 vious work on this collection, a certain amount of confusion and 

 misidentification has been discovered, and it has in consequence been 

 necessary to discuss some species in addition to those actually de- 

 scribed by Maskell, and to erect certain new species based on speci- 

 mens confused with Maskell's species. 



Only three of the species currently assigned to the group have been 

 considered previously in connection with the study of the genotypes 

 represented in the collection. One of these is Frenchia casiiarinae 

 Maskell, another is CalJococcus pvlchellus (Maskell), and the third 

 is Solenococcus fagl (Maskell). Additional species in all of these 

 genera are discussed in this paper. 



In the absence of an even approximately adequate basic classifica- 

 tion of the genera comprising the group, no attempt has been made 

 in the following treatment of genera and species to arrange either 

 in any systematic scheme, a simple alphabetical sequence being em- 

 ployed instead. 



As with many other Maskell species, those considered here are 

 often represented by poor or inadequate specimens, and it has conse- 

 quently been impossible to discuss fully the details of the structure 

 of some of them.
