98 APAMEA OCTTLEA. 



of Dactylis glomerata to the first-named larva on May 

 3rd I found I had unwittingly gathered a third larva. 

 All were precisely alike and fed inside the stems on 

 their linings, and on the tender embryo blossoms. 



The larva is tough to the touch, cylindrical, though 

 rather stoutest at the thoracic segments, whence it 

 tapers to the rather narrow, pointed and flattened 

 head, and also gradually to the anal segment. At the 

 date last given (May 3rd) the larvae measured from 

 five-eighths to barely three-quarters of an inch, and the 

 colour of the body was light greenish, there being a 

 dorsal marking of this colour rather broad and of oval 

 shape on each segment, thus forming a string of egg- 

 shapes down the back, defined by a stripe of dingy 

 pinkish or purplish-pink on each side. 



By the 9th of May the larvae had grown to be seven- 

 eighths of an inch long, the green egg-shapes on the 

 back were less distinct, being longer and more uniform 

 in width, and a central pulsating vessel of dingy 

 greenish showed faintly through the skin ; the dingy 

 purplish-pink stripe on either side of the green dorsal 

 line was rather ragged edged; the segments were 

 plump in character, but each had several fine trans- 

 verse wrinkles ; the head, partly retractile within the 

 second segment, was light brown, with the mouth 

 darker, the ocelli black ; the light brown plate on the 

 second segment was divided dorsally by a paler line ; 

 on the anal segment was a semicircular pale brown 

 plate, very shining, like that on the second segment 

 and the head ; the skin generally had scarcely any 

 gloss, though glistening a little along the sides in 

 places, below the pink stripes aud above the spiracles ; 

 these last were dirty whitish, finely outlined with 

 black, situated on the trachea, which showed through 

 faintly as a pale thread. (W. B., Note Book III, 

 261.)
