A NEW SPECIES OF METANGA FROM FRANCE. 
By Kenneto J. Morton, F.E.S. 
In examining a small lot of Trichoptera taken by Dr. 
Chapman last summer in the Alps of Dauphiné, forwarded by 
Mr. Lucas, I found four insects, which at first sight I supposed 
to be Metanea flavipennis, Pict. On confronting these, however, 
with McLachlan’s figures, I was surprised to find that the details 
did not agree satisfactorily, and on looking over the material in 
my collection it was manifest that there were two species, and 
these rather distinct ones, mixed together, examples from 
Murgtal (Ris), Silvaplana (Morton), and Carinthia (Klapalek), 
pertaining to the species described and figured by McLachlan, 
while others from the Val Bedretto (Ris) were evidently the same 
as Dr. Chapman’s. I asked Dr. Ris to go over his material, and 
he confirms my view of the matter. The only explanation of 
the oversight that can be offered is the identical general appear- 
ance of the two species, and even with regard to the profile view 
of the genitalia the similarity is rather remarkable. I propose 
to describe this hitherto overlooked species as— 
Metanewa chapman, n. sp. 
Very similar in appearance to H. flavipennis, Pict. Head, 
thorax, palpi, legs, and under side of body testaceous, hairs golden ; 
abdomen above darker. Basal joint of antennz and between the 
posterior ocelli slightly fuscescent. Spines of legs black. 
Anterior wings narrow and elongate, pale yellowish, shining 
neuration concolorous, pubescence of membrane dense, golden 
Discoidal cell about the same length as its footstalk. Posterior 
wings whitish, subhyaline with pale veins; first apical cell variable, 
but narrower at the base than second; second broader, moderately 
oblique at the base in the direction opposite to the first; third 
longer than first and second, almost acute at the base; upper branch 
of cubitus furcating about, or a little beyond the level of the 
beginning of the discoidal cell. 
In the male the apex of the abdomen above is rather deeply 
concave, the posterior margin covered with scattered black tubercles, 
the side produced into rather long finger-shaped processes whose tips
