intense velvety black ; then follows a pale stripe, which in- 

 cludes the spiracles ; this is varied with yellow and white, 

 and spotted with black ; ventral surface, legs and claspers 

 smoky pink, irrorated with Ijlack. On the 31st of May tliese 

 larvae, for which 1 am indebted to Mr. Bignall, descended 

 from their food-plant, and changed to smooth and pale brown 

 pupae beneath the dried leaves on the surface of the breeding- 

 cage : another supply, for which I am indebted to Mr. Maw- 

 son, were received exactly a fortnight later, and underwent 

 pupation in precisely the same way on the l4lh, 15th and 

 16th of June. — Edward Netciiwu. 



Description of the Egg and Larva of Toririx miiristrann. 

 — P^ggs laid June 10th, 1864; round, plano-convex, one- 

 Iwenty-fourth of an inch in diameter, of the colour of bees- 

 wax ; laid in irregular clusters, their edges frequently imbri- 

 cated, their upper surfaces marked with minute impressed 

 points : as they ap])roach maturity their upper surfaces be- 

 come much more convex, and marked with irregular cracks 

 or creases, like tliose on the back of the hand : about the 

 9th day the position of the young larva is indicated by the 

 circumference of the egg being greenish, tlie centre main- 

 taining its original yellowish brown colour: about the 16th 

 day there appears a large l)lack spot in each egg, indicating 

 the position of the head of the larva : when hatched the in- 

 tegument remains as a white film ; this occurs in about 

 eighteen days. Larva hatclied June 28th, 1864; yellow; 

 head flattened, jet-black, shining; shield yellow, shining; 

 true legs concolorous with the body, shining ; bristles long 

 and stiff; it has about five short, straight, closely-set anal 

 bristles, set like the teeth of a comb : the habit of the larva 

 at this stage is to get between two leaves of the food-plant 

 (hazel), slightly attaching them by silken threads, and eating 

 away the parenchyma : when disturbed tliey wriggle and hop 

 by a thread. July 8th. Its only change appears to be in the 

 colour being yellowish green and the body being of an equal 

 width with the head. July 28th. One month old ; green, with 

 a rather broad pinkish dorsal vessel. August 11th. 'J'he 

 larva; are now about five lines in length, of a translucent sea- 

 green colour, the viscera rendering it darker on the back, 

 with long scattered bristles ; head jet-black, shining, some- 

 what rugose; labruni chesnut; shield green, shining, showing
