NO. 1412. SOME JAPANESE LEPIDOPTERA—DYAR. 955 



BINTHA CHINENSIS Felder. 

 TAKE-KEMUSHI. 



Leech" puts this species in Arxocera, but incorrectly, as that g-enus 

 has the male antennae simple while they are pectinated in the present 

 species. The spv3cimens are labeled ''''Procrisfuneralts''''dkndi perhaps 

 really are that species, i. e. Ad-sclta funeralia Butler; but Butler's 

 description, though very short, disagrees with the specimens before 

 me. The abdomen is said to be black, the claspers 

 and proboscis horn yellow, while in the form before 

 me the body is leaden bluish as described by Felder, 

 the tongue seems concolorous, and the claspers are 

 entirely concealed. 1 place the species in Bintha^ 

 although the palpi are rather short, not exceeding 

 the front, and there are no spots on the wings.

l^ood plant: Arundinarta japontca. nensis, lakva. 



The larva resembles the preceding, but is more 

 elongate and has long hair from the terminal and latei'al warts. Pale 

 dorsally, brown siil)ventrally, the warts black, those of joints 3, 4, 

 12, and 13 enlarged and distinctly black. 



Family PYRALID^. 



MARGARONIA PYLOALIS Walker. 

 KUWA-HAMAKI-MUSHI. 



Food plant: Morus alba. 



Nearly allied to the North American J/. sihiUalls Walker, and with 

 the same food habit. It webs up the leaves of mulberry. Head 

 brown, body green with the small tubercles black. An addorsal and 

 a stigmatal whitish line. 



PYRAUSTA POLYGONI, new species. 

 Al-NO-MUSHI. 



The moth looks very much like P. nuhilalis Hiibner, and has prob- 

 ably been confused with it. P. nuhilalis occurs in Japan. I have a 

 specimen from Professor Matsumura labeled '^ Stalk borer, injurious 

 to Panicmn family," which shoAvs that the larva has a different food 

 habit. The present species has the dark streak at base of vein 1 of 

 fore wing, characteristic of the subgenus 3[/<'r<itl>< Warren. The 

 wings are not quite as pointed as in niibllalis and veins 4 and .5 of hind 

 wings arc farther spaced at origin. The sexes are colored alike, the 

 lines as in the female nuhilalix^ but the outer line is softer and less
