ART. 25 INSECTS OF ORDER TRICHOPTERA MARTYNOV 19 



inferior appendages very broad, with concave hind edge, if seen from 

 the side; second joint similar to that of Goera -fissa Ulmer (Kwan- 

 timg), but its upper rod-shaped process is longer than in that spe- 

 cies, and by a rounded excision beneath it separated from the lower 

 triangular prominence, as in Goera squamifera Martynov. Tenth 

 segment forming, above, a narrow plate, soon dividing into two 

 long and slender brown processes, acute at their ends. Penis long 

 and apparently resembling that in Goera squamifera Martynov. 

 Length of body, 6 mm. 



Remarks. — Judged by the structure of the male genitalia this 

 species appears to be allied more to Goera squamifera Martynov. 



Ty^e.— Male, U.S.N.M. No. 43157. 



Sfecimens examined. — Four males, from Suifu, Szechwan, March- 

 April.
