NO. 1550. NEW COCHLIDIID MOTHS—DYAR. 567 



Type.— C'At. No. 10339, U.S.N. M. 



The species with its straw-colored wings and diverg-ing- brown lines 

 suggests a species of Coclilidkm. 



PLATYPROSTERNA CERES Druce. 



Mr. Schaus captured four males in good condition at Iguala, Guer- 

 rero, Mexico, altitude 12,-iOO feet, in June, 1906. 



PEROLA CLARA, new species. 



Brownish ocherous, the hind wings with an orange tint. On the 

 fore wings are faint red-brown radial streaks on the discal and sub- 

 median veins; a red-brown line from costa just before apex gradually 

 curves more and more inward, reaching the inner margin a little before 

 middle. Expanse, 26 mm. 



One male, Salina Cruz. Oaxaca, Mexico, September, 1906 (W. 

 Schaus). 



7)/i>^.— Cat. No. 10340, U.S.N.M. 



This species has almost exactly the same markings as P. dr'uceoides 

 Dognin, from Ecuador, but is a much smaller species. The dark line 

 on the forewings, too, is slenderer and curves inward in a different 

 manner. 



PROLIMACODES DIVIDUA, new species. 



Head and thorax dark brown, abdomen concolorous Avith the hind 

 wings. Fore wings chocolate brown on the costal half, pale brovv'n on 

 the inner half, the two colors separated l)y a line that begins at the 

 base near costa, runs parallel with it for nearly one-third its length, 

 then curves down nearly to tlie submedian vein, runs along near this 

 for another third, then goes obliquely, crenulated on the veins, to the 

 apex; basal incision of the brown above submedian vein filled with 

 silvery white, which runs out along the division of the colors to apex, 

 diffused on the lower side; a broad patch of dark color along the inner 

 margin, diminishing toward the tornus. Hind wings pale chocolate 

 brown. Expanse, 27 to 30 mm. 



Two males, Cuernavaca, Mexico, June and August, 1906 (W. 

 Schaus). 



Ty/vr'.— Cat. No. 10341, U.S.N.M. 



Of the North American species this comes nearest to P. scapha 

 Harris. 1 had at hrst thought it a variety of this, but the serrations 

 of the antennte are longer and the brown costal area is differently out- 

 lined. A female before me, from Rinconada, Vera Cruz, Mexico, 

 probabl}^ belongs here, but the costal area is more rounded, as in 

 scapha. It differs therefrom in the greater size of this patch, its 

 crenulate outer edge and the pale area along the inner and outer 

 margins being strewn with dark scales.
