the colour a dark chestnut-brown, the surface smooth

MlANA FURUNCULA. 



Plate LXVIII, fig. 4. 



In April last I had the pleasure to receive several 

 larvae of this species, for which I am greatly indebted 

 to the most kind exertions of Dr. Knaggs, who has 

 thus brought another unknown larva to light. 



These larvae were found feeding in stems of Festuca 

 arimdinacea, the interiors of which they entirely de- 

 voured, leaving only the outer cuticle, in which, towards 

 the end of June, they spun a very slight envelope of 

 silk, and changed to the pupa state, the moths appear- 

 ing from July 9th to 19th. 



This larva, when two-thirds grown, is about 

 three-quarters of an inch in length, very smooth and 

 shining, cylindrical, and plump, but tapering a little 

 at both extremities, and the head very small and 

 slightly flattened. The ground colour is a yellowish 

 flesh tint, and it is marked on each segment with three 

 transverse bands (the widest in front) of dull mottled 

 reddish or dingy pinkish, very distinct on the back, 

 but paler on the sides, and through them run the 

 dorsal and subdorsal stripes of the clear ground 

 colour. The spiracles are minute and black; the 

 head dark reddish- brown ; a small pale reddish-brown 

 plate on the second, and another on the anal segment. 

 The anterior legs dark brown, and the prolegs tipped 

 with dark brown. 



As the larvae became full grown their markings 

 faded away until they appeared uniformly of a yel- 

 lowish-white, with a dark grey pulsating vessel, show- 

 ing through some of the anterior segments. (W. B., 

 E.M.M. IV., 137, November, 67.)
