lobe, the small one posterior to the other; two tiny dots near 

 middle of anterior margin; tubercle in front of spiracle faintly 

 blackened on upper margin. Tul)ercle ii of. segment o lias lieavy 

 black ventral margin, especially anteriorl3^ Some markings on 

 margin of tubercles i, ii and iii of segment 12; tul)ercles of other

Pupa. — 12 mm. long; uniform very pale brown; wing-cases 

 extend to posterior margin of 4th al)dominal segment, leg-cases 

 and antenna-cases extend about one and a half segments farther; 

 otherwise similar to O. accepta. The pupa is formed in slight 

 cocoon in the caterpillar's "retreat." Pupal period 11 to 12 

 days. 



Omiodes blackburyii (Butl.) Palm Leaf-roller (Plate II, tig. 10) 



" $. 30 mm. Antennal ciliatioas one-fourth. Abdomen pale ochreous, 

 segmental margins white. Fore wings pale brownish-ochreous, veins 

 ochreous-whitish, separated at origin by a dark fuscous suffusion; an 

 ochreous-whitish line, acutely angulated outwards in middle, from one- 

 fourth of costa to one-third of inner margin, posteriorly margined with 

 dark fuscous, anteriorly by abroad dark fuscous suffusion between veins; 

 an ochreous-whitish transverse discal spot ; an ochreous-whitish line 

 from three-fourths of costa to three-fifths of inner margin, sinuate out- 

 wards beneath costa, below middle forming an acute triangular projec- 

 tion outwards, anteriorly margined with dark fuscous, posteriorly by a 

 broad dark fuscous suffusion between veins ; a slender interrupted dark 

 fuscous hind-marginal streak ; cilia whitish-ochreous, with a fuscous 

 line. Hind wings rather densely haired towards inner margin ; pale 

 whitish-fuscous ; an indistinct darker discal spot ; a cloudy whitish line 

 from two-thirds of costa to anal angle, with an acute projection outwards 

 in middle, anteriorly narrowly, posteriorly broadly suffusedly margined 

 with dark grey; a slender dark grey hind-marginal streak; cilia whitish, 

 with a dark grey line." [Meyrick, Trans. Ent. Soc. London, p. 214, 

 1888.] 



Expanse of males often Bo mm.; females o3-o8 mm. The 

 females are usually paler than tlie males, have less fuscous suf- 

 fusion, often with ferruginous-ochrcous suffsion in fore wings, 

 and the lines less distinct. 



This is about tlie largest of our Omiodes si)ecies. It occurs on 

 all of the islands of tlie group, especially where coconuts grow. 

 The caterpillars feed on the leaves of various species of Palms,
