the absence of the strong yellow tinge on the wings, and 
in most of the longitudinal nervures (and parts of the 
neuration otherwise) being interrupted with blackish of 
which there is rarely a trace in MZ. trigrammus: in this 
latter respect it agrees with Klug’s description of I. /etus 
from Arabia Deserta : “ale hyaline, nervis fusco-albidoque- 
variegatis reticulate ;” this latter is usually considered a 
synonym of trigrammus. 
I have undescribed species of the genus from the 
Province of Oran.

Macronemurus elegantulus, sp. n. 
Pale yellow. On the antennal region is a large blackish space (in 
which the antenne are seated) forming a broad shining black tri- 
angle below the antennz the lower edge of which is slightly excised 
(like a broad “\): antennze brownish black, the two basal joints 
_ yellow, somewhat annulate with brownish beneath ; on the swollen 
vertex is a blackish -shaped spot: pronotum scarcely longer than 
broad, very slightly narrowed anteriorly, on the middle a broad 
blackish longitudinal band the whole length, dilated anteriorly, 
and on each side a narrow abbreviated blackish line, not reaching 
the anterior margin ; mesonotum with a very broad median black 
band dilated anteriorly, and another on each side at the base of the 
wings : metanotum having the anterior lobe margined with blackish, 
and a spot on each of the other lobes ; on each side of the thorax a 
blackish maculose band : legs pale yellow, anterior and intermediate 
tibiee spotted with black externally, tibia at apex and the tarsal 
joints at their apices furnished with black spine-like hairs, on the 
back of the posterior femora of the ¢ is a series of long curved 
hairs diminishing in length towards the apex : abdomen for the most 
part blackish but with a (sometimes obsolete) yellowish maculose 
stripe on each side, clothed with short whitish hairs ; appendages of 
the ¢ as long as the last two segments, curved, cylindrical, yellowish, 
clothed with long hairs. 
Anterior wings narrow, only slightly dilated to the apex which 
is scarcely angulate, the posterior slightly shorter : hyaline, the edge 
all round finely blackish, neuration for the most part whitish, but 
the costal nervules are usually slightly fuliginous, as are those in
