12 NEW OR LITTLE -KNOWN CRANE-FLIES FROM JAPAN 



narrowly connected with the band just described along vein M; the super- 

 numerary cross vein in cell C is usually isolated from the other markings; 

 the small spots at the ends of veins R-i, Ri+5, M1+2 and Ms are isolated. 

 Venation : cell R2 comparatively shallow, veins R2 and R3 diverging slightly 

 at the wing-margin; cell 1st Mi large, ample; petiole of cell Mi comparatively 

 short. 



Abdominal tergites reddish brown, the caudal margins very narrowly and 

 indistinctly gray pruinose; sternites, especially the basal segments, yellow, 

 narrowly margined laterally with dark brown. Male hypopygium with the 

 lateral gonapophyses almost straight, the tips considerably twisted. 



Habitat.— Japan. Holotype, d" , Saitama, May 29, 1919, (R. 

 Takahashi). Paratype, d", Mt. Takao, Musashi, May 15, 1913,

Genus LIMNOPHILA Macquart 

 Limnophila (Lasiomastix) flavella new species 



General coloration brownish yellow, the tarsi brown; wings yellow, a small, 

 shiny black spot at their extreme base; apical cells of the wings pubescent. 



Male. — Length, 4-5.3 mm.; wing, 5.6-6.8 mm. 



Female. — Length, 5.2 mm.; wing, 5.4 mm. 



Rostrum and palpi reddish yellow. Antennae yellow, the apical half of 

 the flagellum more infuscated; antennae moderately elongated, if bent back- 

 ward, extending to beyond the wing-base. Head brownish yellow, the front, 

 anterior part of the vertex and along the inner margin of the eyes whitish 

 silvery. 



Mesonotum brownish yellow, sparsely poUinose, without stripes. Pleura 

 pale yellow, sparsely yellow poUinose. Halteres pale, the knobs indistinctly 

 darker. Legs yellow, the tarsi, with the exception of the metatarsi, dark 

 brown. Wings rather narrow, light yellow; veins pale brown; a small, shiny 

 black spot at the root of the wing; a sparse pubescence in cells 2nd Ri, Ro, 

 R3, Ri, Ml, M2, Mi, Cui, and sometimes in the end of cell 1st A. Venation: 

 r far before the tip of Ri; Rs long; R2+3 longer than the basal deflection of 

 Ri+i] r-m long, arcuated; petiole of cell Mi about equal to the cell; basal 

 deflection of Cui before midlength of cell 1st M 2. 



Abdomen brownish yellow. Male hypopygium with the outer pleural 

 appendage blackened at the tip, which is split into two short teeth; inner 

 ])leural appendage pale, bifid, the outer or caudal arm about four times the 

 length of the inner arm, slightly enlarged distally; inner arm slender, bearing 

 hairs at the apex; penis-guard strongly arcuate beyond mid length. Ovi- 

 positor with the valves very elongate, as in the closely allied L. (L.) pilifer 

 Alexander, from Japan.
