The noticeable thing about this list is that nearly all the 

 species are importations from elsewhere. The Aspidistus maskelli, 

 lately described from the Sandwich Islands, has just been found 

 by Dr. Noack in plenty at Campinas, Brazil. So it may soon 

 be with most of the remaining five possibly endemic species, 

 that they will be found to occur elsewhere ; in fact, it is not 

 certain that we really know anything about the native Coccidae 

 of the Sandwich Islands, or, indeed, whether there are any ! 



The description of a new species follows : — 



Aspidistus persearum, n. sp. 



5 . Scale suboval, 1^- mm. long, 1 broad ; slightly convex, 

 brownish cream-colour; exuviae sublateral, concolorous, inconspicuous. 

 The scale is easily distinguished from that of A. destructor, being quite 

 opaque, dull, more coloured, and not so flat. 



? . Of ordinary form, pale lemon yellow. Four groups of cir- 

 cumgenital glands, of six orifices each. Three pairs of lobes, the 

 median ones brown, the others colourless ; median lobes close together 

 but not quite touching, parallel, elongate, considerably longer than 

 broad, the sides straight, the rounded ends minutely serrate ; second 

 lobes similar in shape but smaller, also serrate at ends, their ends 

 reaching slightly begond the level of the tips of the median lobes ; third 

 lobes small, notched on the outer side. Squames branched and 

 serrate, as in allied forms ; there are seven beyond the third lobe, 

 Spines large, but not longer than the squames. Anal orifice small, 

 close to the base of the median lobes. 



Hab. Scales gregarious on under side of leaf of avocado 

 pear (Persea persea = P. gratissima) from Honolulu, 1898. Found 

 by Mr. Alex. Craw in the course of his horticultural quarantine 

 work at San Francisco. The portion of the leaf attacked turns 

 brown beneath, reddish above. A. persearum is a species of 

 Aspidistus, s. str., allied to A. destructor, Sign. It is in no way 

 related to A. persea, Comst.
