mixed grey and black, those on the 2nd and 3rd segments amber brown; 

 along each side the hairs are of a lighter brown; the spiracles are golden; 

 head legs and claspers shining black.^° 



Wilson counts the head as segment 1. In his figure (fig. 9) 

 the dorsal and lateral hairs on segments 2 and 3 are distinctly 

 amber-brown. 



Egg greenish white, larva with very long and dense hair, which is red 

 on the anterior segments and on the others black above and only red 

 laterally, placed on warts with a whitish gloss; when touched roughly the 

 hairs sting slightly, but do not cause any noteworthy inflammation. From 

 September until May, at the edges of woods, on meadows in the woods, on 

 nettles, dandelion and many other low-growing plants. Attempts to breed 

 aberrations by feeding the lai'vae with certain plants (foliage of walnut, 

 etc.) were not successful. Common." 



The hair is red on the anterior segments above and on the 

 others black above and only red laterally. 



Larva.— Meyr. Brit. Lep. 42; Barrett, Lep. Brit. 268, PI. 7, fig. 1. Black; 

 hairs .very long, black and grey, browner on sides and on 1st and 2nd 

 somites reddish brown; head black. Food-plants: Urtica, Plantago, etc. 

 8-5. Great Britain." 



The hairs on first and second somites are reddish brown. 



Larva. Head black with reddish-brown spot at sides; body black; each 

 body-segment with two deep-black tubercles on subdorsal line, one on supra-, 

 subspiracular and basal lines; tubercles on subdorsal and subspiracular 

 lines thickly covered with longer or shorter light greyish yellow hairs; 

 tubercles on subspiracular and basal lines with short reddish brown hair; 

 thoracic legs black; abdominal legs dark brov^nn. Food-plants: hemp, rape, 

 •mulberry-tree. Ribes grossularioides. — Prof. Sasaki.'^ [Nothing is said of 

 segments 2 and 3 (counting head as segnaent 1) being reddish brown or 

 amber-brown.] 



It will be noted that Hampson, Wilson, and Seitz state that 

 the hair on anterior segments 1 and 2 (or counting head as 

 segment 1, on 2 and 3, Wilson) is red, reddish brown, or amber- 

 brown. Sasaki does not notice this, and it is not apparent in 

 the original figures of my larvae. This is possibly the distin- 

 guishing feature of the larva of phssosoma, the normal Japanese 

 form of caja. 



In the original figure of my Hakodate larva (Plate II, fig. 10) 

 the spiracles are white; this is not mentioned by the foregoing 

 authors.
