weeks, for altbough jtll mine had spun up by June 27th, some of them 

 havino- don.e so directly after capture, none of the few cocoons then 

 opened contained pupae. On August 2nd, however, several cocoons 

 were cut open in order to ascertain their contents, and all contained 

 pupae, though some of these had assumed this state only shortly 

 before, as was evident from their comparatively pale colour. 



PUPA. 



The following description was made on August 5th from four 

 pupae selected for the purpose, and including two representatives of 

 each sex ; their colour showed that they had been in this state souie 

 little while: — 



Length of (? , 7*5 mm. ; of ? , 8*75 mm. Greatest breadtli of cj , 2 mm. ; of ? , 

 2'5 mm. Rather stout, in proportion to its lengtli, in both sexes, and tapering 

 gradually from the end of the third to the end of the sixth abdominal segment, and 

 then abruptly to the anal extremity. Segmental divisions very clearly defined. 

 ISkirL smooth, with no noticeable hairs. Head and thoracic segments smooth, slightly 

 polished, reddish-tawny, the former armed with a cocoon -opener, which consists of 

 two short stout projecting spikes, placed side by side. Eye-cases prominent, the 

 eyes showing through as large round black spots. Ayitenna- and leg-cases with 

 well-defined margins, smooth, somewhat polished, concolorous with wing-cases ; in 

 the S J the antennal and hind-tarsai cases are of equal length with the wing-cases 

 but in the ? ? they are shorter than these, and only reach to the middle of the fourth 

 abdominal segment. Wing-cases reaching in the S 6 to the end, and in the ^ $ to the 

 middle, of the fifth abdominal segment, smooth, somewhat polished, tawny-orange. 

 Abdominal segments dull and unpolished, reddish-tawny above, tawny-orange 

 beneath. Most of these segments have, dorsally, two rows of blackish, or black- 

 tipped, raised spikelets, pointing somewhat backwards, one near the anterior margin, 

 the other just behind the middle. Both, however, are wanting in the first abdominal, 

 while the posterior row is absent from the last two segments of the <? , and from the 

 last three of the ? . The intervening segments mostly show a brown band along 

 their posterior margin. Anal extremity armed dorsally with several strong blackish 

 spikelets, pointing obliquely backwards, and ventrally with two rather larger and 

 stouter ones, somewhat widely separated, pointing downwards ; it also bears a few 

 oi'ange-brown bristles. 



ISome of the larvae, owing chiefly, no doubt, to the excess of 

 moisture in the decaying mass of leaves in which they tried to spin 

 up, failed to pupate satisfactorily, but almost every one that did so 

 produced a perfect imago, a fine series of 105 specimens, of which 51 

 were ^ S, and 54 were $ ?, being reared. The moths emerged 

 August 12th to October 19th last, and displayed remarkable regu- 

 larity in leaving the cocoon between 7.45 a.m. and noon, the only 

 exceptions being three that came out in the afternoon during a
