EEEBIA BLANDINA. 31 



ribbed, but not deeply, with about thirty longitudina 

 ribs, and with very shallow transverse reticulations ; 

 the colour is pale greenish-yellow, afterwards pale 

 pinkish-grey, speckled with claret-brown. 



The larva when small has the head large and rounded, 

 is stout forwards, and tapers from the middle to the 

 tail ; it is greyish with reddish-brown dorsal, sub- 

 dorsal, lateral, and spiracular lines, the lateral lines 

 being broader than the rest ; the spiracles black, with 

 another brown line below them ; the skin covered, 

 though not very closely, with short, stout, curved 

 pellucid bristles. 



It hybernates when rather over the length of two 

 lines ; creeping down the blades of grass, and hiding 

 in the thickest parts of the tufts. Soon after com- 

 mencing to eat again in spring, the larva assumes 

 somewhat of a greenish tint, but after a moult the grey 

 colour returns. 



In May one was described which had then assumed 

 the last dress. It was three-quarters of an inch in 

 length, stout in proportion, thickest at about the fourth 

 segment, the back tapering somewhat in a curve, the 

 belly flattened, with the prolegs placed well under it ; 

 the head globular, scarcely narrower than the second 

 segment; the anal segment bearing two not very promi- 

 nent blunt points ; each segment bearing on the back 

 five transverse ridges studded with minute raised warts, 

 emitting fine short tapering bristles ; the head was also 

 covered with still more minute bristle-bearing warts. 



The ground colour is pale drab, the warts being pale 

 whitish-brown ; the dorsal stripe is blackish-brown, 

 most intense on the hinder segments, and enclosed by 

 two lines of a paler drab than the ground colour; 

 there is a broad subdorsal stripe of paler drab, growing 

 narrower as it approaches the anal point, edged above 

 with a greenish-brown thread, and below with blackish 

 or brownish dashes, that almost form a continuous 

 line, the interruptions occurring at the beginning of 

 each segment ; below this come two thin pale lines,
