SOME NEW SCALE INSECTS OF JAPAN. 



147 



Note : — With regard to this species, Prof. Green has given me the 

 following remark : " This resembles A. bambusœ Bdv. superficially, but 

 differs from that species in several important particulars. In the first place 

 the marginal fringe is of a bright pink color. I note that the marginal 

 series of paired glands is single on the abdomen but irregularly double on 

 the thorax. There are numerous simple circular glands immediately 

 within the paired series, and bands of similar pores connect the stigmata 

 with the margin. There are no supplementary paired glands on the 

 dorsum." The writer should state here that he has not been able to 

 recognize the double series of paired glands on thorax, mentioned by Prof 

 Green. 



A.steroleeaniutii hemisphœricum, sp. nov.

 convex in dorsal aspect. Color of dried examples pale straw to pale 

 greenish yellow, with a dark brown patch in the anterior parts represent-

 colorless.

 prominent hairs which project beyond the margin. Chitinous lip of anal 

 aperture dense and conspicuous. Marginal series of 8-shaped glands 

 double, except close to end of abdomen, where it becomes single ; inner 

 series of simple marginal pores well-defined and very numerous.

 places of Japan. Collected by the writer, September 19 10. 



Note :- — In a letter to me, Prof. Green has remarked : " This insect 

 approaches A. bavibusœ Bdv., but shows the following differences. The
