This species may be distinguished by the white waxy 

 puparia, and by the large forked spines on the abdominal 

 margin. 



Aspidiotus vitiensis, sp. nov. Plate I., fig. 2. 



Female puparium greyish-white as a rule, but varying 

 somewhat in colour according to the bark of the tree ; form 

 probably nearly circular, but so many are usually massed 

 together that it is difficult to make out the outline ; slightly 

 convex. Diameter probably about ^in. Pellicles subcentral, 

 yellow. 



Male puparium similar in colour to that of the female, but 

 smaller and more elliptical. Length about ^m- 



Adult female brown, pegtop-shaped : length about T V n - 

 Abdomen ending in two large median triangular lobes with 

 serrated sides, not adjoining : on each side is a small cylindri- 

 cal lobe, followed by a forked spine, and, after an interval, two 

 smaller conical lobes and another forked spine : the abdominal 

 margin bears also a few other spines. Four groups of spin- 

 nerets : upper groups 6-10 orifices, lower groups about 15. 



Hah. In Fiji, on " several different forest-trees." My 

 specimens were sent by Mr. Koebele. 



Aspidiotus unilobis, sp. nov. Plate I., fig. 3. 



Female puparium really whitish, but generally covered 

 by so much dense black fungus that it seems black, and is 

 very difficult to distinguish. Form circular, slightly convex ; 

 pellicles orange, central, forming a minute boss. Diameter 

 about ^in. 



Male puparium white, elongated, not carinated. Length 

 about oVn. 



Adult female dark-orange, pegtop-shaped ; length about 

 Jjjin. Abdomen ending in one single median dome-shaped 

 lobe, on each side of which are a few fine hairs. No groups 

 of spinnerets. The margin of the abdomen is finely striated 

 and minutely crenulated. 



Adult male unknown. 



Hob. In Australia, on Acacia sp. (tea-tree), Mount Vic- 

 toria, New South Wales. 



The single median lobe sufficiently distinguishes this 

 species. A similar character is seen in Cliionaspis querciis, 

 Comstock. 



Aspidiotus aurantii, Maskell. 



I am constantly receiving specimens of this insect from 

 many widely-separated localities, and on many different trees. 

 It is not at all confined to the orange, and is, seemingly, 

 ubiquitous in warm temperate countries. The colour varies a 

 little, and lately I have had some from Honolulu, on a species
