184 [Augurt, 



paid on May 12th was more successful, for a very short search re- 

 vealed a larva of a very 3acfra-like appearance, snugly stowed away 

 in a stem. About half a dozen roots were brought home, potted and 

 covered with gauze-topped cylinders, and tlie larvge, or rather the green 

 frass, from them could be plainly seen at intervals on the stems of the 

 food-plant (which it may be as well to state is Scirpus lacustris* the- 

 common club-rush) ; they appear to move freely from stem to stem, 

 hollowing each one out and stunting its growth, frequently causing 

 the stems to turn brown, and gradually decay. Pupate in the stem in 

 a light silken cocoon. The first imago, a ^ , appeared on June 23rd, 

 the last, a $ , July 2nd. Six specimens in all, two males and four 

 females. I will now give a description of the larva: — 



Length, about 5^ lines, somewhat attenuated. Colour yellowish-green, and very 

 shining and smooth. I could detect no hairs on the body ; a few scattered hairs on 

 the head, which is black, divided by a whitish line. Second segment very dark 

 brown. The dorsal canal can be very plainly seen through the semi-transparent 

 skin. Full-fed last half of May. Pupa greenish-yellow, wing cases darker. 



Although the habits of this species, both in the larva and imago 

 states, are very similar to its near ally, lanceolana, the appearance of 

 the larvffl is very different. Perhaps it would be as well to give here 

 a short description of the larva of this latter species by way of com- 

 parison : — 



Larva of Bactra lanceolana ; — Length, from 5i to 6 lines, when fully extended. 

 Colour greenish. Head and second segment both black. Each segment after the 

 second contains six plainly visible blackish spots. Two on either side of sub-dorsal, 

 and one just above and slightly in advance of each spiracle. Full-fed first week in 

 May. The above description was made on May 12th, when nearly all I found were 

 in the pupa sba,te ; va&ny oi furfur ana, on the contrary, were not more than half 

 grown on the same date, and only one could be found full grown.

Carpocapsa nimhana. — I first met with this local and rare Tortrix towards the 

 end of May, 1889. One fine ? emerged from a large pot containing beech nuts 

 gathered the previous September. I did not meet with any more until this season, 

 when another fine $ emerged from a pot containing a lot of dead, moss-covered 

 beech bark brought last autumn from the same locality. A search on the beech 

 trunks on the first opportunity (May 26th) enabled me to add three more to my 

 collection, two $ and one ? . — A. Thurnall, Stratford New Town : July, 1894. 



Sutalis chenopodiella. — I have taken five or six of this, local insect at rest on 

 fences in this neighbourhood during the past month (June). — Id.
