13. Chionaspis (Phenacaspis) aucubae Cooley, 



Tokyo, on Aiicuba japouica Thunb., collected by the writer at 

 Hibiya Park, Tokyo City, September, 1907. 



14. Chionaspis (Phenacaspis) latissima Ckll. 



This species is very common all over Japan on leaves of Distylium 

 raccmosnm S. et Z. 



15. Chionaspis kinshinensis, new species. (PI. IX, Figs. 34-37.) 



Female Pnpariuin. — Pale straw color, opaque, rather thick in texture, 

 very broadly and roundly dilated, so that the width usually eqvials the length ; 

 slightly convex. Pellicles pale ; first exuvia oblong, segmentation distinct, 

 last abdominal segment yellow, about .3 mm., second exuvia subcircular, about 

 .5 mm. Ventral scale white, very thin. Size about 2 mm. 



Male Puparimn. — Unknown to the writer. 



Adult Female. — Oblong, slightly pinkish in color ; abdominal segments 

 distinct. Last abdominal segment presenting the following characters : The 

 anterior group of spinnerets consists of five to eight, the anterior laterals 

 twenty to twenty-five, posterior laterals about twenty-one. The median lobes 

 are large, oblong, contiguous at the proximal end, and widely separated at 

 their distal extremities ; their margins serrate ; the second lobes of each side 

 incised near its lateral end, the mesal lobule being almost three times as 

 large as the lateral ; third lobes well formed, with incision at middle, the 

 mesa! lobule being larger than lateral. The plates are arranged as follows : 

 I, I, 2; the first one between mesal and second lobes, the second between 

 second and third lobes and the third beyond the third. Spines as usual. 



Fukuoka, on the trunk of Querciis sp., collected by the writer, 

 1907. 



This species is allied to Chionaspis colcmani Kuw. in the shape of 

 scale, color and texture, but is distinguished from the latter by the 

 structure of the last abdominal segment. 



16. Mytilaspis (Lepidosaphes) buzenensis, new species. (PL IX, Figs. 



38-40.) 



Female Piiparium. — Long and narrow, straight, widening gradually toward 

 posterior extremity. Color dark brown, opaque, with a very narrow, irregular, 

 flattened border, which is whitish gray and transversely marked by curved 

 lines of growth. Pallicles very pale yellow, subtransparent, occupying about 

 one third the total length of the scale ; the first exuvia oval ; segmentation 

 distinct ; antennal filaments well seen, about .3 mm. long : second exuvia very 

 much larger than the first, posterior extremity yellow, about .8 mm. Ventral 

 scale incomplete, broadly divided. Length about 2.5-3 mm., width about 

 .5 mm. 



Male Puparium. — Very much resembles that of female, but smaller ; line of
