SERICOSTOMATID^ 



Key to the genera. 



a^. Forks 1, 2, 3, 5 present in both wings; discal cell in hind wings open; 



male palpi not upcurved and heavily haired or scaled Goera. 



a'. Forks 1, 2, 3, 5 not all present in both wings; discal cell in hind wings 

 open. 

 b^. Fore wings very broad; basal joint of male antenns without processes. 



Neolepidostoma. 



6\ Fore wings rather slender; basal joint of male antennae with processes 



above Dinarthrodes. 



The above genera occur in Java, but none is yet recorded from 

 the Philippines.

Key to the genera. 



a\ Radius in fore wing not running into the first apical sector. 



Anisocentropus. 

 a'. Radius in fore wing running into the first apical sector, also in hind 

 wing. 

 b*. Fore wings very long, rather narrow, and slightly falcate at tips ; hind 



Avings as broad as, or broader than, the fore wings Asotocerus. 



b\ Fore wings broad, not falcate at tips; hind vdngs narrower than the 

 fore wings Ganonema. 



Anisocentropus magnificus Ulmer. 



One from Los Banos. A black-winged species with a blue 

 sheen to the fore wing and a hyaline oblique bar across middle. 



Asotocerus umbrosus sp. nov. Plate II, fig. 18. 



Yellowish brown ; antennse yellowish, plainly ringed with black 

 at tips of the joints; legs yellowish. Wings very dark brown, 

 costal area and along anal veins almost black ; hind wings fully 

 as dark. Vertex with a prominent, median, rounded depression, 

 a little longer than broad, and rather broader behind than in 

 front; posterior warts large, nearly reaching the eyes, and not 

 their long diameter apart. Fore wing with venation as figured, 

 strongly falcate at tip ; in hind wings forks 2 and 3 are subequal, 

 fork 1 as far back as origin of the pedicel of fork 3. 



Expanse, 36 millimeters.
