17 (G9) Aspidiotus lataniae (Sign.). 



on Giiava. So identified by Mi*. Sanders for Van 

 Dine. I always called it cydoniae, but the syn- 

 on\any of this group is in a bad state of confusion. 



18 (70) Pseudaonidia clavigera Ckll. 



on Chinese banyan, fig, Bombay mango, Macadamia 

 ternifoUa, Santalum freycinetianum, citrus; Ho- 

 nolulu. A well distributed tho obscure species 

 aboiit Honolulu. Thanks to Mr. Marlatt's fine 

 table of this genus in Proc. Ent. Soe. Wash., the 

 identification of this species was made easy and 

 certain. Pity we lack such tables for Pseudo- 

 coccus and other Coccid genera.
