THE PUPA Oil CHRYSALIS. 97 



examination would be found to contain either a 

 minute chrysalis or a little yellow grub with a 

 black head, which is the larva of the Tinea in 

 question. 



The larva of the Tinea Taliatella makes a si- 

 milar kind of tent, with the exception that the 

 webbing is so disposed as to look like a roof of 

 small white tiles, or rather scales. 



In the Beetle tribe some of the larvae, when 

 about to change, cement portions of the surround- 

 ing earth together, so as to form a secure retreat, 

 as in the case of Clythra Longimana. In some 

 instances these cases are lined with a silky sub- 

 stance, or, as it were, varnished with a slimy 

 secretion. 



A larva that infests Beehives constructs for itself 

 a kind of gallery or covered way as it goes for- 

 ward, the interior of which is lined with a smooth 

 web, so tough that Bees in vain attempt to expel 

 the intruder by piercing it with their stings. 

 It is proof against all their efforts, and they fre- 

 quently desert their hive in despair at being unable 

 to get rid of the invader. This constructor of sting- 

 proof galleries has received from Eabricius the cha- 

 racteristic generic name " Galleria," to which is 

 added the specific denomination " Cereana," in al-
