134 Mr. R. M‘Lachlan’s Afonograph of the 
short. Anterior wings long and narrow, somewhat dilated to- 
wards the elliptical apex ; hairy clothing long and dense; fringes 
long; radius not bent; discoidal cell short and triangular, closed 
by an oblique transverse vein; a transverse vein uniting the upper 
margin of the discoidal cell to the radius, and two others placed 
below that cell (perhaps another more towards the base); forks 
2, 8, 4 and 5 present. Posterior wings not folded, much shorter 
than the anterior and very narrow; the costal margin suddenly 
and acutely elevated about the middle; beyond this elevation the 
margin is slightly excised to the apex; fringes very long; no 
discoidal cell; perhaps one or two transverse veins; forks 2, 3 and 
5 present. Legs moderately long, the intermediate tibiz and 
tarsi dilated in the female; anterior tibize with two minute apical 
spurs; intermediate and posterior tibiae each with two pairs of 
rather long and unequal spurs. Abdomen slender. In the male, 
there is sometimes a pointed lobe from the middle of the upper 
margin of the last segment ; app. sup. and inf. sometimes both 
present, or the app. inf. are absent. In the female the apex of 
the abdomen is furnished either with a very short ovipositor, or 
with a very long upeurved one. 
Larva unknown; frequenting slowly-flowing rivers. 
The species are small, unicolorous, and difficult to separate, 
but the two here described cannot possibly be confounded,
