occasions and have no doubt as to the identity of the larva 

 figured. My larva, moreover, agrees well with the figures and 

 description given by Nawa.^^ 



Nawa states that "the young larvae [of Diagora japonicali hatched from 

 the third brood of the imago, appearing at Gifu, Honshu, from the middle 

 of September to the beginning of October, are at first ashen-grey in colour 

 and during hibernation rest on dead enoki leaves their color assimilating 

 well with the dry, dead leaves so that they are not easily discovered." 



I have found them myself as late as February concealed in crevices of 

 the bark. Nawa further states that "when full grown the larva is green 

 with two bifurcated horns on the head; two large horns on segment 7 

 (not including head as first segment), smaller horns on segment 2, 5, 10 

 and two on the anal segment." This agrees with the number of horns on my 

 larva. 



The pupa is described by Nawa as light green. It is repre- 

 sented with oblique white streaks in his figure, but Nawa does 

 not mention these streaks in his description. I bred an imago 

 of D. japonica from a light green pupa with oblique white streaks 

 on May 18, 1901, so that they evidently exist as figured by Nawa. 

 Pryer remarks of the larva : 



it hibernates on the bark of the twigs of the tree (enoki), and is then 

 grey, but as soon as the leaves appear in spring" it changes its skin and 

 becomes green. It is of the usual Apatura, tapering, cylindrical shape, with 

 strongly bifurcated head. 



The following description is taken from my original figure. In 

 the description I have taken the head as the first segment, so 

 that the horns are placed upon segments 3, 6, 8, and 11, respect- 

 ively, instead of, as in Nawa's description, on segments 2, 5, 7, 

 and 10. Nawa counts the segment succeeding the head as seg- 

 ment 1, while I count the head as segment 1. 



Larva. — Length, 56 millimeters when full grown. Apaturid 

 shape; green; two cephalic horns; five faint yellowish, oblique, 

 lateral stripes; whitish, longitudinal, subspiracular (or supra- 

 pedal) stripe from head to tail; short white longitudinal line 

 from head to first pair of spines on segment 3; anal segment 

 strongly bifurcated into two parallel horns. Nawa does not 

 mention the oblique stripes in his description. 



It appears from Nawa that Pryer gives the time of appearance 

 of the imago as June, August, and October. Miyajima gives it 

 as June and September. Both Pryer and Miyajima are agreed 

 that there are only two broods of the insect in the year. Nawa
