underside is considerably lighter in color, and the neuration is 

 yellowish and quite distinct. The spots on the superiors are the 

 counterpart of those above, except that there are two small spots 

 instead of the first one of the row above. The inferiors have 

 three spots of same color, the first in the third subcostal space; 

 the second in the fourth subcostal space, and the third in the first 

 median interspace. Fringes of superiors dark, and oi interiors 

 same as above. Body and antennae above dark brown; below 

 body, palpi and antennae yellowish, with a dark stripe down the 

 centre of the abdomen. 



The species above is almost the exact counterpart of ocola Edw. 

 but smaller, and below is very close to panoquin and panoquin- 

 oides. I have specimens from California received from Mr. H. 

 G. Dyar and Dr. Blaisdell, and also specimens from Texas.
