 [Topomesoides.] — Most closely allied to Topo')nesa Walk., but vein 8 and 9 

 both terminate at the costal margin, 10 originating closer to the cell than 7, 

 the discocellular of the hindwing is more oblique (the cell anteriorly consid- 

 erably shorter than posteriorly) and veins 6 and 7 of the hindwing are 

 separated at the base, 7 really originating from the anterior margin of the 

 cell.— Type: T ("Aroa") jonasi Btlr.'-^ 



The type of Aroa jonasii, male, was from Yokohama. {Joyias.) 

 Strand erects a new genus for jonasii, which was left by Leech 

 provisionally in Aroa with the following remarks:''^ 



I have left this species in Aroa although it does not appear to be rightly 

 placed therein, and a new genus will probably have to be made for its 

 reception. 



In June, 1901, I found a hairy larva, on an unknown tree, at 

 Myoken-zan, near Kobe, Settsu Province, Honshu, and a female 

 imago, which I identified at the South Kensington Museum as 

 Aroa jonasii, emerged some time during the same month from 

 the pupa resulting from this larva. When the imago emerged, I 

 also identified it from Butler's figure.'^ The moth is a common 

 one and has always been well known to me as Aroa jonasii. 

 Owing to press of work my artist was unable to figure the larva 

 before it entered the pupal stage, but he figured the pupa on 

 June 20, 1901, in three aspects (Plate I, figs. 8 and 9). I de- 

 scribe the pupa from my original figure as follows : 



Pupa. — Dorsum green with a few yellow markings, three on 

 each side; spiracles brownish; wing cases whitish; suspended 

 by a silken pad attached to a leaf of the food plant. Kami- 

 mura,i5 a Japanese lepidopterist of Shizuoka, Honshu, who bred 

 imagos of jonasii on several occasions, gives figures of the larva, 

 the pupa, and the imago. His figure of the larva resembles in 

 form that of the larva from which my female jonasii emerged 

 in June, 1901. However, I am not able to remember anything 

 about the coloration of my larva except that it was dark and 

 hairy. He describes his pupa as follows: 



Pupa. — Color bright green ; it hangs down attached by two or three
