narrowed, then prolonged more or less into a point, with 

 the margins slightly serratulate. 



The male scale is narrower than the typical M. newsteadi. 



This species was found by the author on Codiceum sp. in 

 a green-house in Tokyo. It is a very destructive pest, par- 

 ticularly to the above named plant.

This species was found by the author on Quercus 

 (Pasania) cuspidata (Shii) in Tokyo. Previous to this, 

 A. Craw, San Francisco, had recorded it on the same host 

 and on JElceagnus from Japan.

This species is widely distributed, being found nearly all 

 over the Empire. The author found it on the following 

 plants: Pinus austriaca, Pinus sp., Pinus thunbergii, Tor- 

 reya nucif era, Abies jirma, and Picea bicolor, in the grounds 

 of the Nishigahara Agricultural Experiment Station, Tokyo; 

 on Pinus sp., Kubotesan, Kiushiu; on Pinus sp. in Shi- 

 gaken, and on Podocarpus chinensis in Wakayama-ken. A. 

 Koebele has recorded it on Pinus densijlora, Miyanoshita, 

 Japan. 



The specimens collected in Wakayama-ken, on Podocarpus 

 chinensis, are slightly different from the others, although 

 the differences are not sufficient to make a new species or 

 variety. The female scale is light brown, narrower than 

 the others. The spinnerets are fewer in number, particu- 

 larly those of the posterior lateral groups, and of the middle 

 one of the anterior row of three groups.
