Newly-hatched Ruralid Larvje. 



Fig. 1. — Newly-hatched larva of Edwardsia iv-albumx2>3. [One side only is 

 shown.] 



Fig. 2. — Newly-hatched larva of Strymon pruni x 33. [The dorsal hairs of both 

 sides are shown, but those of the near side are cut short to avoid 

 confusion, the hairs on scutellum are also omitted.] 



Fig. 3. — Newly-hatched larva of Ruralis betrtlaex2>2>. [On prothorax the whole of 

 the scutellum is shown, and on the mesothorax the dorsal hairs of the 

 further side.] 



Fig. 4. — Newly-hatched larva of Bithys quercus x 33. [Treated in the same way as 

 fig. 3. One hair of further side is also shown on the metathorax.] 



These figures are from camera sketches of larvEe, not actually alive, as they are 

 then difficult to examine, but freshly placed on slides in Farrant's medium. No 

 attempt was made to show the abundant dark skin-points which are characteristic 

 of all these larvas in the first instar, but are wanting afterwards, being then 

 possibly represented by the minute, rounded, and uncoloured eminences of the 

 same order of size as the skin-points ; nor are the fine spicuhe of the hairs more 

 than indicated. The elongation of the "neck," due to a little pressure in mounting 

 and most marked in fig. 1, exceeds that shown here when the larva is feeding and 

 pushing its head into narrow openings, almost mines, in leaves and buds, but 

 is absent when the larva is at rest or walking. The feature is even more marked 

 in the Lycaanid larvae.
