NONAGRIA GEMINIPUNCTA. 43 



two perforations, the smallest, below, having an ex- 

 cavated channel under a small piece of the reed cuticle, 

 which led to the larger perforation ; this hole was 

 stopped with grey silk from within, and altogether 

 appeared less conspicuous than the other above de- 

 scribed. 



One of the larves, which was extracted from its 

 stem for the purpose of being figured, died on the 

 25th of June ; the other was only looked at, and, the 

 split in the reed which had been made for that purpose 

 being carefully bound up again, it went safely through 

 its changes, and appeared as a moth on July 23rd. 



The full-grown larva was of the usual Noctua form, 

 one and one-eighth of an inch in length, moderately 

 but not very stout, tapered a little just at each end, 

 cylindrical, all the legs well developed. It was of a 

 deepish flesh-colour, the skin without much gloss, of 

 a wax- like texture in appearance ; the face and the 

 lobes of the head were dark brown and shining, be- 

 tween them on the crown the skin was pale flesh- 

 colour ; the shining plate on the second segment was 

 of rather a deeper flesh tint, and dorsally divided by a 

 line of paler ; the plate on the anal flap was of a shi- 

 ning pale brownish tint and semi-transparent; the 

 dorsal vessel just visible as a stripe of a tint of flesh- 

 colour barely darker than the ground; two parallel 

 lines of faint whitish flesh-colour ran rather inter- 

 ruptedly along the spiracular region, dimly suggestive 

 of the branchial apparatus beneath the skin ; the oval 

 spiracles were dark grey outlined with black ; the 

 warty tubercular spots were shining, of a pale brown 

 colour, each furnished with a very fine hair ; the 

 anterior legs spotted with pale brown ; the ventral and 

 anal prolegs greyish, tipped with darkish brown. 



The pupa, judging from the empty skin, seemed to 

 be lying free in the interior of tbe reed stem, head 

 uppermost; its length a little more than seven- 

 eighths of an inch, rather slender, stoutest about the 

 thorax, the wing-cases short in comparison with the
