which are transversely narrowed, occupying half the circumference of the joint 

 and regularly arranged over the whole length in a single row; the 4th dusky 

 at the apex, without sensoria; the 5th dusky at the distal portion: the Gth 

 dusky at the apex and middle; the relative length of joints ahout as follows: 

 [11-148, IV-50. V-47, VI-51 (20 + 25). Rostrum rather stout, reaching the 

 middle coxae. The 1st and 2nd obliques on the front wing curved: the 3rd 

 obsolete at the base twice forked; stigmatic vein faintly indicated: hind wings 

 with 2 very slightly divergent obliques ; hooldets 3. Basal 2 abdominal segments 

 each on the durum with a, pair of small blunt dusky tubercles which are subequal 

 in size: the 3rd. 4th. 5th and 7th segments each on the dorsum with a pail - of 

 smaller similar tubercles which are almost subequal in size; the 6th and 8th 

 each at the middle of the dorsum with a pair of very small similar tubercles, 

 of which those on the Sth are smaller; basal 4 segments each near the side 

 with a very short blunt tubercle that is dusky excepting that on the 3rd segment. 

 Cornicles dusky, small, very slightly or scarcely constricted at midlength, 

 somewhat expanded at the base, almost as long as wide at midlength. Cauda 

 constricted at the base, with some very long bristles. Anal plate bilobed, each 

 lobe somewhat narrower than the Cauda, with some very long bristles. Legs 

 slender, furnished with many moderately to rather long setae; tibiae almost as 

 stout as the 3rd antenna] joint: hind tarsi almost as long as the basal part of 

 the last antennal joint. 



Body — -about 2.0 mm. Antenna — about 1.7 nun. 



Fore wing — about 2.5 mm.. 



Host. — Zelhowa formomna, attacking the young leaf. 



Distribution. — Formosa,: Mush a and Baikei in Taichu-prefecture. 



Some specimens were collected by the author and Miss. Rubikdon on May

This species is easily distinguishable from 31. zellcowae Takah. (Proe. 

 Ent. Soc. Washington, xxi, 7, p. 174) by the longer 3rd antennal joint which 

 is provided with more sensoria, as well as by the dusky cornicles, The basal 2 

 antennal joints seem to be somewhat dusky.
