is fleshy at the base, more chitinized at the tip, its caudal or outer 

 margin grooved to receiv^e the outer appendage. Viewed from 

 above, 9th tergite concave, with a projecting median lobe; anal 

 tube conspicuous, more pointed at upper end than in japonica 



One male (Vial No. C; Tokyo, Japan; August, 1912); I give 

 the above description to supplement Westwood's brief character- 

 ization. The species agree with harbipes Meigen (Europe) in its 

 conspicuously hairy legs. 



Limnophila (Pceciloslola) japonica, sp. n. 

 Wings spotted; tibi;e and femora tipped with lirown. 

 Male. — Length 10-13 mm.; wing 9.8 mm. Female. length 15 

 mm.; wing, 11-12.3 mm. 



Male. — Rostrum and palpi dark brown; antennse dark 

 brownish black, except segment three, which is pale yellow basally, 

 the tip brown; antenna short, if extended backward it would 

 barely reach the wing basis; segment one elongate, as long as the 

 succeeding three combined; segments 2-5 broad, oval-pyriform, 

 gradually becoming more cylindrical; segments 6-16 cylindrical 

 more elongate toward the end; front, vertex and occiput dark 

 brown.

 Halteres long, stem yellow, knob brown. Legs: coxa? and 

 trochanters dull brownish yellow; femora light yellowish brown,

 Sc rather brighter; \eins yellowish brown; wing spotted with

 Vial A), there are large brown spots at origin of Rs, tip of Sc and 

 fork of R2^.^, and abundant pale brown dots over the wing surface; 

 in a second specimen (cr') the wing disk is heavily marked with 

 Isrown, a series of brown marks in the costal cell, a large square 

 blotch at origin of Rs, another at tip of Sci extending partly down 

 across the cord; others at tips of Ri, R2 and Rs; large, paler 

 brown dots in all the cells of the wing. Venation (see fig. 2, pi. III). 

 Abdomen: tergites brownish; sternites dull yellow, apical
