hield-shaped mark- 

 ' Interpreting my 



tion. The larva is allied also to yafada., as I do not detect either 

 caltrope spines or the detachable terminal ones of Euclea^ but it is not 

 a degenerate form like the North American Natada nasoni^ since the 

 spines are well developed and the coloration of a warning character 

 rather than adapted for concealment. 



Horns of subdorsal row short on joints 3, 12, and 13, longer on 1, 

 very long on 5 and 11, minute on 6 and 10, small on T to U, all spined. 

 Side horns short on joint 3, rather long on -1, 

 absent on 5, with the spiracle moved up, moderate 

 on (> to 12. Skin subgranular shagreened. The 

 color is partially destroj^ed in the inflated speci- 

 mens. Graeser briefly describes it from larvjt? 

 which he saw at Cha))arofka and Blagowescht- 

 schensk, in Amurland, as ""dark green, with a ,'■ 

 ing covering most of the back of dark red-brown, 

 larva? b}' this, they are as follows: Purplish brown dorsally, including 

 a diffuse white dorsal band with dark edges, distinct only centrall3^ 

 Sides green, just covering the lateral horns of joint 1, reaching up to 

 the subdorsal horns on joints 7 to 9, retreating to the lateral horn on 

 joint 11, but covering joints 12 and 13, and in an angular patch about 

 the subdorsal horns of joint 11; green spots below 

 the subdorsal horns of joints 4 and 5. A white 

 broken lateral band with dark edges; subventral 

 edge pale, with a dark line above. The depressed 

 spaces are but little developed and not distinguish- 

 able in the specimens. 



The cocoon is spun on the twigs of the food plant. 

 It is elliptical, usually white, with strangely shaped 

 broad brown streaks, looking, as Pryer says, like a 

 bird's &g^. Some of the cocoons are evenly mixed 

 white and brown. They are firmly attached to the 

 twig, and will often break before they can be de- 

 tached. Like other Cochlidians, it has a variety of 

 food plants, an}^ smooth-leaved tree ))eing a('cepta])le. 

 Under these conditions it is a species most easily imported. I have 

 had specimens from San Francisco, California, brought on young trees 

 from Japan. There is also reported the importation of what was 

 evidently this species to Hamburg, Germany," but the species has 

 never becoine acclimated anywhere that 1 know of.
