GUIDE TO INSECTS. 



The Rhopalocera or Butterflies have the antennas terminating in a 

 club. This is very variable in shape and extent and is sometimes very 

 slight. The hind wings are not united to the front ones by a frenum.

The Heierocera are divided into numerous families. The drawings 

 and explanatory labels are in course of preparation, in the meantime 

 a series of specimens will be found temporarily placed in table 

 cases 43-48. 



In Table-case 39 will be seen a series of specimens illustrating 

 the life-history of the common Mulberry Silk-moth, Bombyx mori. 

 This species has been cultivated for so many centuries that its origin 

 is uncertain, but it is probably a native of China. 



On a shelf on the east side of the gallery are models and drawings 

 illustrating the habits of various species, many of them of interest on 

 account of the injury they do to fruit trees, &c. 



In wall case 8 on the west side of the gallery are some interesting 

 compound cocoons of gregarious moths. Attention is particularly 

 called to one of Anaphe panda from S. Africa (263) in which there 

 is a crowd of caterpillars, and by its side a similar nest (265) in 

 which the caterpillars have spun their cocoons (figs. 45, 46). When 

 the moths come out they escape by the opening at the top. 

 (Further particulars about this nest will be found in Table- 

 case 44.) 



In the same case is a somewhat similar nest from Madagascar
