of the hind- wing nearly from the cubitus, while the 2nd oblique much 

 separated from the cubitus, on the costa with 3 hooklets, the prolon- 

 gation of the 2nd oblique not meeting with the first oblique; cauda 

 short, blunt; legs short and of a paler colour. 



Length of body 1.8mm.; exp. tegm. 6.5rnm.; antennae 0.6mm.. 



Nymph -Body pale fulvous; the first 2 antennal joints broad, the 

 3rd and the following joints wanting sensoria; wing-sheath reaching 

 beyond the tip of the hind femur. 



Galls- Very large, some of them measuring about 60 by 40mm. and 

 of an irregular bag-like form, sometimes fusiform, sometimes water- 

 nut-shaped, producing globular protuberances, always having a large 

 cross-iike slit on each apex of the latter; greenish yellow in colour, 

 with soft, short hairs and small fuscous granules. 

 Hab. - Hokkaido (Sapporo). 

 F. P. - Rhus semialata; galls on the branch of it, evidently 



transformed from the leaves, collected by Prof. K. Miyabe. 

 Nom. Jap. - Nurudeno-dmimifushi. 



According to the description and figures of Prof. K. Shirai 1. c, 

 this insect seems to be the same species, but owing to the insufficient 

 diagnosis of the alated imago, I can not identify it. In his figure, 

 the body-length is about 3 mm., and its wing-expanse about 6.5mm,, 

 while in my species the body-length is 1.8mm., and its wing-expanse 

 nearly the same.
