which Mayr has given the manuscript name of Eurytoma Schreimeri. It 

 infests the seeds of the plum in Astrakan, Russia, and causes considerable 

 damage to the crop, the infested fruit dropping while still quite small.

THE JAPANESE COCCID^. 



BY T. D. A. COCK.ERELL, BOULDER, COLORADO. 



In the Bulletin of the Imperial Central Agricultural Experiment 

 Station of Japan, Vol. 1, No. 2 (1907), Mr. S. I. Kuwana has published a 

 new list of the Coccidse of Japan, with numerous new species. I am 

 indebted to Dr. L. O. Howard for the loan of the work, which is probably 

 little known in this country. A very beautiful Icerya, illustrated by 

 coloured figures, is introduced as /. okadce. It is, however, exactly like 

 /. seychellaru7ti (Westwood), and I do not see any reason for separating 

 it from that species, except that according to the figure the femur is 

 much stouter. Cerococcus muratce. is a most interesting species, but I think 

 it should be known as Solenophora muratce (Kuw.). Pseudococcus takce 

 (Dactylopius takce, Kuw.) is a new species on bamboo ; the figure of the 

 antenna? shows nine joints, although the description indicates only eight. 

 From the figures, and the general appearance, one might suspect the 

 insect to be a Phenacoccus. Ripersia oryzce, Kuw., found at roots of 

 rice, has large subcylindrical caudal lobes, and cannot be regarded as a 

 true Pipers ia ; no doubt the discovery of the larva and male will throw 

 light on its affinities. Aclerda (?) biwakoensis, Kuw., on Phragmites, 

 should be compared with A. japonica, Newstead; it might be the same, but 

 for apparent differences at the caudal end, Pulvinaria Kuwacola, on
