70 COREMIA PROPUGNATA. 



The pupa is enclosed in a silken cocoon, and is 

 about two-fifths of an inch in length, rather dumpy, 

 smooth, and highly polished; thorax cylindrical; 

 wing-, eye-, and antenna-cases boldly defined ; the 

 abdomen attenuated, but not rapidly, towards the 

 anal point, which, however, is fine and sharp. Colour 

 dark brown, the antenna-cases and outer edges of 

 the wings pale brown ; the whole changing to deep 

 mahogany-brown just before the emergence of the 

 imago. 



All the brood, forming a very fine series, emerged 

 about the middle of August. (George T. Porritt, 

 4th January, 1877; B.M.M., February, 1877, XIII, 

 213.) 



COREMIA QUADRIFASCIARIA. 



Plate CXL, fig. 10. 



The caterpillar of Coremia quadrifasciaria is clearly 

 divided into two colours by a line running from the 

 head to the extremity of the last pair of claspers ; the 

 spiracles lie in this line of division. The dorsal 

 space is brown, variegated in shade from a light 

 smoky brown to almost black by interrupted lines 

 running throughout its length, interspersed with 

 numerous light-coloured blotches ; four rows of 

 minute warts run down this space, from each of 

 which a short bristle is emitted. The head is slightly 

 smaller than the second segment, and of two shades 

 of brown. The spiracles are black. The ventral 

 space is of a very light brown, having a tinge of pink, 

 and variegated, like the back, with blotches of a much 

 lighter shade. The caterpillar thickens towards the 

 middle, tapering gradually to each extremity. 



It assumes the form of an Ionic volute when 

 annoyed. 



These larvse were hatched on the 28th July from eggs 

 deposited by a female captured a day or two previously.
