MIORODONTA BIOOLORA. 79 



length was 11 lines or 23j mm, and 14 lines by the 

 22nd, when it was figured the first time, and figured 

 again on the 24th, when it had attained its greatest 

 length, about 18 lines. It was again figured on the 27th, 

 as during the last three days it had grown decidedly 

 stouter ; the head was now finely reticulated on the 

 crown with whitish or bluish-green, the back of the 

 palest greenish-white was soft and shining, the black 

 spiracles each in a white ring on the upper edge of the 

 bright yellow spiracular stripe, the belly a deep green, 

 the lines bluish-green, the wrinkles across the back of 

 each segment, four or five in number, made the sub- 

 divisions rather less noticeable than before, but they 

 still equalled the segmental divisions which were very 

 lightly defined. 



I found this species, a very delicate one, requiring 

 much care and attention ; one spun up in birch leaves 

 on the 29th, when three only remained alive, two of 

 these also spun up between birch leaves on the 31st 

 July, and the remaining one died the next day. 



On the 18th of June, 1883, I bred one specimen of 

 the moth, a male ; the other two pupge standing over. 

 I found the cocoon spun between the leaves made of 

 greenish-grey silk rather thin, but of tolerably compact 

 texture ; it was of rounded oval form, with the sur- 

 rounding portions of the leaves very closely united. 

 The pupa skin, and one of the remaining pupae, measured 

 7-g- lines, very cylindrical, of almost uniform moderate 

 stoutness, the thorax slightly keeled, but rounded off 

 at the head, the tail also rounded, the wing-covers 

 closely wrapped to the body, the two abdominal rings 

 below them being deeply divided ; the abdomen tapers 

 but little; a fine punctate roughness was nearly all 

 over; the colour brownish-black and rather shining.
