( xxiv ) 



Stauropus mediata is another very brilliant larva which 

 nothing will eat. Its colours are green, bright yellow, 

 blue and black. The moth is however far from common, 

 owing to the attacks of Ichneumonidte. The larvte of 

 EiMemmistis chlorozonea is also well concealed in the last 

 stage by the adoption of allocryptic methods. It feeds upon 

 lichen and is white in colour : when full-fed it completely 

 covers itself with the lichen, and uses the same to form its 

 cocoon, which is suspended from the branches or trunk of the 

 ti'ee upon which its food-plant grows. The moth itself when 

 at rest exactly resembles the lichen, and is most difficult to 

 find. 



" The larva of Lophostethus dumolinii is certainly a distinct 

 case of mimicry, as it is far more like a Saturniid larva than one 

 of the Sphingidaj, and does not even rest in the manner usual 

 among 8phinx larvse. It is greatly persecuted by ichneumons, 

 and very diflicult to rear unless taken full-fed or at any rate 

 in the last stage. 



" Ophmsa mormokles and ecJio, lai'ge half-loopers, almost 

 exactly resemble the bark of the trees upon which they 

 rest, and their colour varies so as to match that of the 

 particular tree on which the larvae are found. Ophmsa 

 indeterminata, on the other hand, is conspicuous, and does not 

 possess the power of colour adjustment, so that three or four 

 different forms may be found upon the same food-plant : it is 

 moreover I'efused by birds. The very common larvfe of M. 

 armigera also appears in three or four different forms, which 

 are relished by birds. These larvse however prefer to feed 

 concealed inside lilies and the pods of peas. The conspicuous 

 black and white larva of Diaphone dominica also feeds inside 

 the thick leaves of lilies, bvit this garden pest is unfortunately 

 refused by birds. 



"Geometers I need not refer to, as they are much the same 

 as at home, only far less numex'ous. 



" There are a great many other larvifi which might be 

 mentioned, but, as they produce moths as yet unnamed, I 

 will leave for another occasion, when the species have been 

 determined or described. 



" The genei'al conclusion may be accepted that black and
