168 Mr. R. M‘Lachlan’s Monograph of the 
ventral margin of last segment not produced in the middle ; ven- 
tral horny lobe slender and testaceous, 
Expanse of fore-wings 43 lines. 
I possess two examples, one of which is from Taunton. It is 
probably equally common with the preceding, but overlooked. 
The characters given by Curtis, “ wings narrower and more 
Janceolate,” render it probable that this is rightly determined. 
The two female types of pygme@a, in Stephens’ Collection, also 
appear to have decidedly narrower wings. 
Genus Curmarra, Leach. 
Antenne thin, not so long as the wings, the basal joint not 
longer or stronger than the others; placed very widely apart. 
Head rounded, densely clothed with hair. Ocelli present. Maxil- 
lary palpi long; basal joint short, second joint very long with a 
tuft of hairs at the apex, third shorter than the second, fourth still 
shorter, fifth rather longer than the fourth and somewhat flexible. 
Labial palpi long, basal joint thin, second joint longer and much 
dilated, third joint flexible. Mesothorax robust. Anterior wings 
narrow, the costal and dorsal margins nearly parallel, apex 
rounded; hairy clothing short and rather dense; discoidal cell 
apparently open; just before the ramus discoidalis furcates it is 
interrupted by a small naked cell-like space, and both branches 
of it end in long furcations ; upper branch of the anterior branch 
of the ramus thyrifer forked, the lower simple. Posterior wings 
shorter and rather broader than the anterior, rounded at the 
apex; a small closed discoidal cell ; otherwise the arrangement 
of the apical veins is very similar to that of the anterior wings. 
Legs moderately long, the intermediate tarsi somewhat dilated 
in the female; anterior tibiz in the male spurless, in the female 
with one short apical spur ; intermediate and posterior tibize each 
with two pairs of rather long spurs. Abdomen robust, especially 
in the female. Anal appendices small. 
Larva unknown ; inhabiting swift torrents.
