pedes nigri, femoribus apice tıbiis basi tarsisque quatuor posterio- 
ribus pallide flavis, tibiis tarsisque anticis fulvis; alae diaphanae,

Female. Black. Head and thorax finely punctured. Head 
hardly broader than the thorax. Antennae clavate, much longer 
than the breadth of the head. Prothorax with two whitish trans- 
verse humeral spots. Abdomen sublanceolate, depressed, some- 
what longer than the ihorax. Femora at the tips, tibiae at the 
base and four posterior tarsi pale yellow; fore tibiae and fore 
tarsi tawny. Wings pellucid; veins whitish; ulna less than half 
the length of the humerus; cubitus a little longer than the radius, 
a little more than half the length of the ulna. Length of the body 
1%, line. 
Between /. Laothoe and I. linearis; it differs from the former 
by the shorter and more clavate antennae, from the latter by 
the little less clavate antennae and by the broader fore wings.

Brauchbare Artcharaktere sind in dieser Diagnose nicht vor- 
handen, ein deprimiertes, sublanceolates Abdomen besitzen mehrere 
Arten. Der Vergleich mit 7. lineare (= hordei Harr.) bietet eben- 
falls keine Möglichkeit, die Art danach zu identifizieren, die dem- 
riach als zweifelhaft gelten muß.
