9. Lecanium (Coccus) fukayai, new species. (PI. VII, Figs. 7-10.1 



Adult Female. — Irregularly deltoid, very flat. Color pale green. Anal 

 cleft more than one third the total length of the insect. Marginal spines 

 simple ; stigmatic spines not very long, simple. Antennae usually 6- but rareli^ 

 7-jointed ; third joint the longest ; formula 3, 6, 2, 4, 5, i. Legs well formed, 

 but rather small ; three pairs alike ; tibia longer than tarsus ; tarsal digitules 

 fine hairs ; those of claw unknown ; claw large, curved. Anal plates bluntly 

 pointed, base more than twice as long as outer edge ; at the apex with four 

 or five spiny hairs. Length about 2 mm. 



Ibaraki, on vine, collected by C. Fukaya, March, 1907. Named 

 after the collector, who is now working on Japanese Coccidse under 

 the direction of the writer. 



The present species is allied to Lecanium mangifera Green, but 

 differs markedly as follows: The antenna of L. mangiferce is 8- 

 jointed ; the second and eighth equal and longest, while that of the new 

 species is usually 6- and rarely 7-jointed, and the third is the longest. 

 The extremities of the marginal spines of L. mangifercs are divided 

 into many forks, while those of the new species are simple and 

 pointed. 



10. Lecanium (Coccus) ochnacese, new species. (PI. VII, Figs. 11-15-) 



Adult Female. — Pale yellowish green ; oval in outline, widest at thorax, 

 very thin, broadly flattened, with slight median longitudinal ridge ; stigmatic 

 clefts shallow. Antenna; usually 8-, but rarely 7-jointed; third joint the 

 longest; about .3 mm. long; formula 3, 8, 4, 2, 5, 6, 7, i. Legs well developed 

 and large ; three pairs alike ; tibia much longer than tarsus ; claw large, 

 curved ; digitules ordinary. A row of several strong, spiny hairs on the ventral 

 aspect, between the antennae. Marginal hairs very prominent, divided at 

 extremity ; stigmatic spines three, the median one very long and slightly 

 curved, the other two less than half as long. Anal plates large, outer angle 

 evenly rounded ; outer edge longer than base ; several prominent spines at the 

 apex. Length about 2.5 mm. 



Tokyo, on Eurya ochnacca Szysz., collected by the writer, April, 

 1907. 



This species is allied to Lecanium viride Green, but there are 

 manv differences in the formula of the antenna. 



11. Aspidiotus (Chrysomphalus) aurantii var. citrinus Coq. 



This species is one of the common scale insects of Citrus in 

 Japan, but it is not very destructive.
