not yet captured any root-attacking form of this insect. 



Gall -whan it is full grown measures about 10 mm., roundish, with 

 some irregular granulous protuberances, provided with a long petiole; 

 in the beginning of its formation green in colour, becoming gradually 

 purplish yellow and then crimson-red, especially on its apex; it has a 

 velvety lustre, with numerous white silky hairs, having an exit near 

 the apex; I have counted about 12 galls all over the surface of a single 

 leaf. 



3. Gobaishia ? akinere Sasak. 

 Tetraneura akinere Sasaki, Zool. Mag. Tokyo. Vol. 16, p. 403, pi. 



IV, f. 1-9 (1904). 

 I have not seen this species, so I can not describe it here, according 

 to his figures it most probably belongs to my Gobaishia, for the hind 

 wings have 2 oblipues, but the sensoria of the 3rd to 5th antennal

 and about the 6th joint he has not described at all. Anyhow I must 

 wait to know its details for any future study. 

 Hab. -Honshu (Tokyo). 

 F. P. - Ulmus parvifolia. 

 Nom. Jap. - Akinire-gobaishi.
