418 Mr. Forsayeth on the life-history of 



their escape. I judged the larvae to be near their trans- 

 formation. In a day or two I removed the dried-up 

 eases, and examined the earth in the box ; I found that 

 the larvae had buried themselves under ground, making 

 a loose cocoon of earth and silk woven together. 



Nov. 5th following, " I examined the cocoons, and 

 found the larvae unchanged in each, shrivelled u^d, dry, 

 and dead. I can now find no larvae on the Bambu in 

 my garden." 



Why should these larvae have gone under ground in 

 preference to undergoing their transformation in what 

 would appear to be the natural situation, viz., inside the 

 cylinder, the cylinder being in each case available for 

 the purpose ? 



Compare this larva and its habits with the larva of 

 Tegna hyhlceella ; the resemblance appears to me to be 

 great, yet the latter is placed amongst the Noctuae.
