Entomology. — Among the riches of the Bermudan 

 entomology, I have noticed, among the species of 

 butterflies, the Pieris brassicce, the great garden white 

 butterfly, &c. The Argynnis Paphia, the Heliconia, 

 and the Nymphalis, are common enough at all times, 

 and in almost all situations. Others are abundant

 butterflies are to be obtained only occasionally. The 

 insects belonging to the genus Diurna (or butterflies),

 order, are possessed of four wings, which are gene- 

 rally covered with microscopic scales, frequently 

 exhibiting the most beautiful colours. The larvse 

 are provided with feet and a distinct head ; the 

 mouth of the perfect insect is a long, spiral proboscis. 

 The butterflies, so conspicuous for their beauty, 

 are well-known representatives of this order, and 

 the usual forms of these insects in the larva, pupa, 

 and imago state are familiar to all.
