one half the length of the 5th, anterhinarial very short; wing-sheath 

 relatively long, reaching to the middle of the abdomen; legs subhylinc, 

 with very light yellowish tinge. 



Length of body 1.0 mm.; antennae 0.3 mm. 

 Galls -Pale yellowish drown, with light pinkish shade; somewhat 

 irregular in form, some being fusiform, some united together and pro- 

 ducing globose protuberances, hairs being the some as the other galls of 

 this allied species; exits are very small, round, and few are made on one 

 side of the gall; the holes seem as if to be made by some of the scolytids- 

 insectsand where somewhat fuscous coloured, perhaps by the secration 

 of the insects. 



Hab. -Honshu (Shizuoka). 

 F. P. - Rhus semiarata. 

 Nom. Jap. - Nurude-ibofuslii. 

 Compared with the 3 fore-going insects this is the the smallest one 

 and may easily be distinguished by the regularly ringed secondary 

 sensoria on the 3rd antennal joint.

Closely allied to Nududea Mats. , but differs from it in the follwoing 

 points: 



1. The 2nd, 3rd, 4th and 5th antennal joints each gradually 

 increasing its length, the 5th the longest, nearly twice as long 

 as 3rd, the 2nd somewhat shorter than the 3rd, the 3rd to 5th 

 each witvh a few incomplete annulations. 



2. The first 2 obliqufs of the fore wings united together or branched 

 at the bases, media much narrower than the other veins, stigmata 

 fusiform, at the apices acute andobolete, stigmatic aervureopens
