intruders in the cage. At last one day Mr. Wilbey discovered 

 one of" his larvaD in the act of devouring another of its own 

 species: it began by biting a hole in the back of the larva, 

 and then appeared to suck out the soft interior parts, till it 

 left nothing but the empty skin, which was apparently too 

 tough a morsel for its digestive organs. He afterwards saw 

 another larva in the act of devouring a larva of Cleora 

 liclienaria, which happened to be in the same cage. This 

 would seem to prove that in confinement, at all events, if not 

 in a state of nature, this larva is a cannibal. The cannibalism 

 in this case was certainly not caused by want of food, as my 

 friend had supplies of freshly-gathered lichen up from the 

 forest twice a week. — Bernard Lockyer ; August 8, 1873. 



Description of the Larva of Depressaria Ycatiana, Fab. — 

 Length, quarter of an inch to five-eighths of an inch. Colour 

 light chrome-green. Form slender, serai-cylindrical, slightly 

 appressed, constricted, with yellowish rings between the 

 segments. Head black, broad, shining; corslet black, broad, 

 having a rather light edge in front. Dorsal streak faint; 

 subdorsal streak hardly perceptible ; papillae indistinct. First 

 pair of feet black ; the remainder green. Spines yellow, 

 strong, but sparse. Feeds upon Daucus Carota (wild carrot), 

 forming a tube by turning the pinnae of the leaves over, and 

 resides therein. It is full fed during the last week in June 

 and first week in July ; it then descends to the surface of the 

 earlh and spins a while, silken, but rather slight covering, and 

 changes to a rather flattened, bright brown chrysalis, in size 

 and shape very like the chrysalis of Gelechia populella, and 

 remains in pupa about three weeks. This larva was dis- 

 covered by Mr. Hodgkinson and myself, in 1871, in West- 

 moreland, and a drawing made then agrees exactly with 

 larvae taken by us in North Lancashire and in South lian- 

 cashire in 1872 and 1873, from which the series before me 

 were bred. — C. S. Gregson ; August 19, 1873.
