GENUS FIOKIJSriA IN THE UNITED STATES. 19 



ENEMIES. 



The following predaceous beetles which have been determined by 



'Mr. E. A. Schwarz, of the Bureau of Entomology, were found by Mr. 

 Sanders preying on the tea scale: Chilocorus hivulnerus Muls., Micro- 

 weisea misella Lee, and CyhocepJialus nigriiulus Lee. As stated 

 elsewhere, when on the Darjeelmg tea these coccids are frequently 

 covered by a parasitic fungus, which doubtless in a measure is effec- 

 tive in holding this pest in check.

This coccid is a very cosmopolitan species and is of common occur- 

 rence on kentias in greenhouses. A complete bibliography of this 

 species is not given, since it has been the subject of numerous papers, 

 many of which, however, are of little value either from a scientific 

 or economic standpoint. 



DISCUSSION OF SYNONYMY. 



A thorough study of the material on Kentia helmoreana, Cycas revO' 

 Ivia, and Camellia which was described by Comstock ^ as Fiorinia 

 cameUix proves this species to be none other than Fiorinia fiorinise, 

 Targ. In 1896 Green ^ described a form known as Fiorinia palmse, 

 but he later reduced it to synonymy. Leonardi,^ in his paper enti- 

 tled "Saggio di Systematica Delle Fiorinise," reduces Fiorinia fiori- 

 nix var. minor Maskell to synonymy, smce Maskell in his meager 

 description merely states that it was given varietal rank, owing to 

 its small size. Assuming that the only character of separation was 

 the size of the scale, Leonardi concluded that the difference was too 

 inadequate to justify even varietal rank. 



A study of the Maskell material revealed a number of characters 

 which are surely of sufficient importance to allow it to remam as a 

 good variety if not raised to specific rank. As will be seen by exam- 

 inmg Plate IV, the median lobes in minor are larger and more chitin- 

 ized, the marginal pores more numerous, varying from six to seven, 

 and the general shape of the pygidium is different. The material of 

 this variety is very scanty and is on the underside of a leaf which is
