'IMiis species is eomnion on all the larger islands of the 

 Hawaiian group, It is perhaps the most common species of those 

 which are particularly grass feeders. The caterpillars are grass 

 f(H'dcrs, occurring with O. accepta. I have found them feeding 

 on PanicuDi pnin'cns, Paspalum conjiigainm (Hilo grass) and 

 Oplisnie/ius composihis ("Honoliono" grass). 



Full-grown cat(ri)illar. — (Plate Ilf, fig. o). Length alxait 

 20 nnn.; head similar to O. accepta with the addition of 

 hrownish markings on the vertex and sides, and a l)laek dot at 

 the postero- ventral angle of head. Cervical shield with l)laek 

 margins to its lateral lohes; two hlack spots in each lateral lohe, 

 the anterior one twice as large as the posterior one, sometimes 

 they are united; on tlie level witli these spots is a hrownisli on(> 

 hetwi'en segments 2 and ;>; hlack upper margin to the tuhercle in 

 front of spiracle. Tul»ercle ii of segment 3 has black low( r 

 margin, thickened anteriorly; on segment 12 tubercle ii has 

 black ventral margin, and tul)ercle iii has black dorsal margin, 

 thickened posteriorly. 



Pupa. — 10 mm. long, medium brown, eyes black, hairs and 

 cremaster similar to O. accepta; antenna- and leg-cases extending
