OF WASHINGTON, VOLUME XII, 1910. 167 



Norape laticosta, new species. 



Pure white ; costa of fore wing broadly black above and below; 

 palpi, orbits, pectus, and all tarsi black; antennas dull red, the shaft 

 partly white-scaled ; head with a little yellow tint. Expanse 28 mm. 



Three males, Iguala, Guerrero, Mexico, June, 1906 (W. 

 Schaus). 



Type: No. 13108, U. S. National Museum. 



Norape tener Druce. 



Archylus tener Druce, Biol. Cent.-Am. Lep. Het., ii, 411, 1897. 



The single type specimen has veins 3 and 4 of hind wing 

 connate, 4 and 5 of fore wing separate, although very shortly 

 so. It therefore must be placed in this genus. The Arizona 

 form, supposed to be the same as the Mexican tener, is referred 

 to here under the genus Ramacu. 



Norape alydda Druce. 



Alpis alydda Druce, Biol. Cent.-Am. Lep. Het., i, 210, 1887. 



I .have a single specimen from Ecuador in poor condition, but 

 apparently this species. The type locality is Costa Rica. If 

 the species are the same the above generic reference will 

 obtain. A specimen kindly sent by Mr. Schaus from Costa 

 Rica proves the present reference correct. 



Genus MICRORAPE, new. 



Proposed for Carama minuta Druce (Biol. Cent.-Am., Lep. 

 Het., i, 168, 1886), which differs from Norape Walker in the 

 loss of vein 8 of fore wings. Sole species, Microrape minuta 

 Druce. Mr. Schaus has presented the National Museum with 

 a specimen of this species collected by himself in Costa Rica. 



Genus REPNOA, new. 



Proposed for Carama imparilis Schaus, which differs from 

 the species of Carama (=Norape) in the short antennae. 



Repnoa imparilis Schaus. 



Carama imparilis Schaus, Proc. U. S. Nat. Mus., xxxix, 334, 

 1905. 



This peculiar species is easily recognized by the dark gray 

 wings with the veins and fringe white. The abdomen is black 

 with a yellow tuft at base and tip. Only the single male 

 type is known to me.
