2^18 THE ENTOMOLOGIST. 



the segments are again transversely wrinkled or divided into 

 narrow sections ; the entire surface is slightly scabrous, and 

 covered with very minute but stiff bristles ; the anal ex- 

 tremities produced into two parallel points directed back- 

 wards. Colour of the head and body either dull olive-green 

 or dull pale umber-brown ; in either case the body has three 

 compound or triple stripes ; one of these is dorsal, and is 

 composed of a medio-dorsal dark smoke-coloured stripe, and 

 two yellowish or whitish marginal stripes, the dark medio- 

 dorsal stripe being in some specimens again divided by a 

 very narrow and indistinct white stripe ; this median com- 

 pound stripe terminates with the 12th segment ; the other 

 compound stripes are lateral, composed of the same colours, 

 and terminating in the anal points. Early in October the 

 larva spins a slight silken covering on a stalk, stem or blade 

 of grass, and, suspending itself therefrom by the anal claspers, 

 is changed to an obese pupa, with the head broadly emar- 

 ginate, the thorax, wing-cases and abdomen gibbose, and 

 suspended in an oblique position by anal cremastrse : the 

 skin of the larva always remains attached to the anal ex- 

 tremity, even after the butterfly has escaped : colour of the 

 pupa dingy green or brown, the antenna-cases barred, the 

 wing-cases streaked with dark brown or black ; the back is 

 also freckled with black, and has four or six white dots. In 

 this state it remains throughout the winter, the butterfly ap- 

 pearing on the wing from the 10th to the 20th of the follow- 

 ing April. The opinion appears universally to prevail that 

 this species is double-brooded, and in this (reasoning from 

 analogy) I feel inclined to concur, although I have never 

 seen an a^stival brood of larva?, nor is such mentioned by 

 Sepp, whom I believe to be the only entomologist who has 

 previously written a life-history of the species. I am in- 

 debted to Mr. Buckler for the loan of a beautiful and most 

 life-like drawing of the larva. — Edward Newman. 



Life-history of Saiyrus Tithonus. — The eggs are laid 

 during July on the blades of grass, and may be described as 

 truncated cones ; they stand erect, the base being broader 

 than the apex, and serving as a very secure attachment to the 

 young grass ; they have sixteen, seventeen or eighteen per- 

 pendicular ribs, and a great number of extremely delicate 

 transverse stria?, only visible under a lens of high power ;
