316 THE CANADIAN ENTOMOLOGIST 



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

 margin grooved to receive 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 barbipes Meigen (Europe) in its 

 conspicuously hairy legs. 



Limnophila (Pcecilostola) japonica, sp. n. 



Wings spotted; tibia? and femora tipped with brown. 



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

 mm.; wing, 11-12.3 mm. 



Male. — Rostrum and palpi dark brown; antennae 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. 



Pronotum and mesonotum dark brown. Pleurae dark brown. 

 Halteres long, stem yellow, knob brown. Legs: coxae and 

 trochanters dull brownish yellow; femora light yellowish brown, 

 the tip broadly brownish black; tibiae with base narrowly dark 

 brown, remainder yellow, except the broad dark brown tip; tarsi 

 dark brownish black. Wings tinged with brownish, cells C and 

 Sc rather brighter; veins yellowish brown; wing spotted with 

 brown, varying greatly in the size of the markings; in one (9, 

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

 fork of R2+3, and abundant pale brown dots over the wing surface; 

 in a second specimien (cf ) the wing disk is heavily marked with 

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

 blotch at origin of Rs, another at tip of Sci extending part4y down 

 across the cord; others at tips of Ri, R2 and R3; large, paler 

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



Abdomen: tergites brownish; sternites dull yellow, apical 

 third of each sclerite brown. Hypopygium (see fig. 10, pi. X) : viewed
