HUTAIICHIA GALATHEA. Fair-. 

 Marbled White Butterfly. 



This chaste and elegant insect is found on grassy 

 places in woods, in the month of July : its wings are 

 slightly indented and variegated with black and sul- 

 phur yellow ; on the under side of the anterior wings 

 it has a single ocellus, or eye-like marking ; and, on 

 the posterior, five obsolete ones. 



The Caterpillar is said to be sometimes green and 

 sometimes yellow, with lines of a darker colour ; 

 above the tail are two short red spines ; the back is 

 set with very short hairs; it feeds on grass. 



As the microscope is, at this season of the year, a 

 delightful and interesting source of amusement for 

 young people, the scales that ornament and cover the 

 wings of butterflies and moths will be found curious 

 and interesting objects. The late Dr. Wollaston, 

 on viewing the striated scale from a wing of the 

 large cabbage butterfly, calculated that there were 

 10,000 lines in the space of an inch. Dr. Skrim- 

 shire says, " The wings of this tribe, some of which 

 display great beauty and variety of shade and colour- 

 ing, have frequently been the subject of microscopical 

 investigation. Some have described the fine powdery 

 substance, that comes off with the slightest touch, 

 and leaves the wing a plain, colourless, and trans- 

 parent membrane, as so many minute feathers, or as 

 down, regularly and artfully arranged. Others have 

 compared it to scales of various colours, overlaying 

 1-4, 5. 3
