Rhodia fugax, Butl. Ann. & Mag. Nat. Hist. (4) xx. p. 480 

 (1877) ; III. Typ. Lep. Het. pt. ii. p. 17, pi. xxvi. fig. 1 (1878). 



Seven males and three females in coll. Pryer. The males range 

 from 82 to 103 millim., but the females are more uniform, the 

 smallest being 122 millim. and the largest 126 millim in expanse. 

 According to Pryer, the larva, which he says is " bright green and 

 resembles a butterfly larva," feeds on cherry and other trees, and 

 the imago appears in November and December ; the cocoon, which is 

 bright green and resembles a pendent leaf, has "a slit on the top, 

 opening by pressure."

 (1877) ; 111. Typ. Lep. Het. pt. ii. p. 16, pi. xxv. fig. 2(1878). 



Seven examples, coll. Pryer (3 males, 4 females). I took two males 

 at Nikko in September, and a female at Oiwake also in Sep- 

 tember. 



According to Pryer, the larva is hairy and resembles a small larva 

 of Caligula japonica.

Several specimens from various parts of Japan, exhibiting much 

 variation. 



Pryer remarks in his Catalogue p. 52 : — " Commonly called the 

 wire-cartridge moth, from the resemblance of the cocoon to the wire- 

 net in a cartridge ; last year it was found feeding on poplars newly 

 introduced into this country. The natives make a strong coarse silk 

 from the cocoon, and a fine gut from the intestines of the larva. The 

 imago appears in October. The larva hairy."

My Japanese examples of this Anthercea vary in colour from a 

 pale brown, through pale reddish brown to " rusty orange " on the 

 one hand, and to olivaceous and fuliginous brown on the other. 

 The markings are subject to modifications within certain limits, but
