 long (distinctly longer than in Blepharocera, 

 for example) and composed of long slender 

 flattened well chitinized mandibles with the 

 apical two-fiflhs of the innei' niaigin finely 

 serrate, and inserted farther back on the 

 head than the other mouthparts: of maxillae 

 consisting of slender flattened tapering blade-

 palpi ; of elongate simple labium consist-

 terminal lobes; and of slender elongate flat-

 wings with venation (fig. 2 ) showing the fol-

 ing or with only a basal rudiment present). 

 Wings clear, with strong iride scent reflec- 

 tions. The legs are long, the three pairs of 

 about equal length, the hind tibiae bearing a 

 single terminal spur, the other tibiae with- 

 out spurs. The taisal claws are large, thick 

 and strong with curved pointed tip, thickh- 

 pectinate except at the tip. The external 

 genitalia consist of a pair of flattened tri- 

 angular dorsal plates. 



Male. The male is slightly sinaller than 

 the female. As the head of the only male 

 specimen was destroyed in the dissection of 

 the Uiouthparts before any examination of 

 the specimen was made, it cannot be said 

 whether the eyes are like those of the female 

 or not: mouthparts like those of the females 

 except that the mandibles 

 are wholly lacking. Wings 

 and legs like female. The 

 jj- conspicuous parts of the 

 external genitalia are a 

 pair of large articulated 

 claspers, a broad ventral 

 plate, and a smaller dorsal 

 plate.

The new species can readily be 



grouped with the four other known 



species assigned to the genus Liponeura 



in Osten Sacken's * paper. The new 



form has in common with the other 



four species an incomplete vein running 



into the posterior margin of the wing 



between veins 4 and 5, a simple (un-
