Opogona saccharcUa n. sp. 



Head metallic fuscous above, pale fawn below. Palpi pale fawn, 

 fuscous externally. Antennae pale fawn, l)asal segment fuscous above. 

 Thorax dark bronzy fuscous, sulphur-yellow posteriorly. Abdomen and 

 legs pale metallic fawn. Forew'ings very long-pointed, sulphur-yellow; 

 a dark fuscous streak along basal sixth of costa ; a very oblique black 

 postmedian line from about % of costa to a little before end of fold, area 

 beyond this metallic fawn with a few violet scales; cilia pale fawn. Hind- 

 wings and cilia ])ale metallic fawn. 12 mm. 



Near O. (Lorjostonia) protodoxa ]\Ieyr., \vhich is c(immon in 

 Australia. 



One specimen, Briti.sh Xew Guinea (Muir). The larva feeds 

 in sug^ar cane similarly to what O. aiirisquaiiwsa does in Hawaii.

"Male and female. 12-18 mm. Head dark fuscous, face bronzy-white. 

 Palpi whitish. Antennae ochreous-whitish. basal and next two or three 

 joints dark fuscous. Thorax yellow, anterior third dark fuscous, .\bdo- 

 men pale grey or greyish-ochreous. Forewings elongate-lanceolate ; bright 

 yellow; a thick dark fuscous streak along basal fifth of costa; apical half 

 beyond an irregular line from middle of costa to beyond middle of dorsum 

 rather dark fuscous except a triangular yellow spot on costa towards apex; 

 small suffused dark fuscous spots beneath costa and on dorsum imme- 

 diately beyond dividing line; cilia dark fuscous. Hindwings fuscous; cilia 

 pale fuscous." [Meyrick. 1. c. above.] 



One female, l^)ritish Xew (niinea (Aluir). The larva feeds m 

 sugar cane similarlv to what O. aiirisqiiaiiiosa does in Hawaii. 



It agrees very well with Meyrick's description, 1)ut not with 

 Felder's figure ; in fact, this figure and Meyrick's description do 

 not exactly agree either. I have no doubt but that my specimen 

 is fuiniccps. It occurs in Java and Ceylon, which are some dis- 

 tance apart, and as it is reported as feeding on coconut pahns in 

 Java,* it might have considerable range in the Malayan and Pacific 

 islands. As Opogona aurisqiiainosa in Hawaii feeds on palm.s and 

 other plants besides sugar cane, it might not be unexpected if 

 fnmiccps was found to feed on both palms and sugar cane.
