 pressi, articulo 3o longo ; antenna subpectinatce ; abdomen 

 alas posticas lunge superans ; alee fascia lata obliqua testacea 

 nigricante submarginata, punctis marginalibus testaceis ; an-

 much compressed ; third joint much more than half the length of 

 the second. Antennae slightly pectinated. Abdomen extending 

 rather far beyond the hind wings. Wings with a broad oblique 

 testaceous slightly blackish-bordered band ; exterior border with 

 testaceous points. Fore wings subfalcate ; costa testaceous ; band 

 undulating on the inner side, dilated towards the costa ; a testa- 

 ceous black-bordered discal point corresponding to the orbicular

Genus LASCORIA. 



Mas. Corpus sat gracile ; palpi erecti, graciles, compressi, 

 flmbriati, articulo 2o arcuato, 3o lanceolato. Antennae setis lon- 

 giusculis. Abdomen alas posticas vix superans ; fasciculus apicalis 

 minimus, subcompressus. Pedes glabri, tibiis anticis dense fascicu- 

 latis. Alae elongatae ; anticae subfalcatae, fissura longissima an- 

 gusta obliqua. 



Male. Body rather slender. Palpi vertical, slender, com- 

 pressed, fringed in front ; second joint curved ; third lanceolate, 

 much shorter than the second. Antennae with two rather long 

 bristles on each joint. Abdomen hardly extending beyond the 

 hind wings ; apical tuft very small, slightly compressed. Legs 

 smooth ; fore tibiae densely tufted ; spurs long. Wings elongate. 

 Fore wings subfalcate, with an oblique narrow deep excavation, 

 which extends from the exterior border to the exterior line. This 

 genus, like Pterhemia, seems to have as much affinity to the Ther- 

 mesiida as to the Deltoidites.
