40 THE CANADIAN ENTOMOLOGIST. 



The members expressed the great pleasure it gave them to v/elcome back 

 to London their esteemed friend and former President the Hev. G. M. Inues, 

 who has been in Quebee for the last four years. 



Mr. Saunders exhibited specimens of the Tree Cricket, Aecanthus niveus, 

 with examples of their destructive work on raspberry canes, and the young 

 wood of plum trees ; this insect deposits its large eggs in a row in the centre 

 of the twig or cane, and thus weakens it so as to cause it to break off from 

 the weight of foliage in early spring. 



A copy of the first two parts of Mr. Edwards' excellent work on the 

 Butterflies of North America was also on the table, the plates of which were 

 much admired. 



A MUSICAL LARVA. 



BY E, B. EBED, LONDON, ONTARIO. 



On September 10, 1868, during one of our regular Monday morning 

 excursions, I captured on a beech tree, a short distance from London, a larva 

 which I judged to belong to the Smerintliiati genus. Its chief peculiarity, 

 to which I wish to call attention, was its power of emitting a singing noise 

 when handled or disturbed. The noise was similar to that produced by that 

 pretty little beetle so common in our gardens, Lema trilineata. This is the 

 only instance of a musical larva that I have met with, nor do I remember to 

 have ever seen any mention in entomological books of a similar case, I 

 should be glad to know, Mr. Editor, if you, or any of your correspondents, 

 have ever noticed this musical power in any larva ? or if you can explain the 

 manner in which the noise is produced, My specimen was full grown, and 

 in a couple of days duly passed into the pupa stage under the earth, in a 

 flower-pot, which I duly deposited in my winter box that I keep buried in 

 my garden, but to my great disappointment it shared the fate of most of the 

 Smerinthian larvas I have ever attempted to rear, and although it survived 

 the winter, it failed to reach maturity. I subjoin a description of this larva, 

 as possibly some of your correspondents may recognise it. 



Length 1^ inches. Body tapering anteriorly. 



Head large, triangular; of a deep shining green color, with lateral yellow 

 stripes, a reddish spot at the apex ; a paler green and granulated on the back 

 of the head behind the stripes. Mandibles black. 



Body apple-green, thickly covered with small greenish-yellow granulations; 

 the anterior segments semi-transparent; on each side seven faint greenish- 

 yellow oblique stripes edged anteriorly with large granulations, the central 

 stripes having a reddish tinge, the last stripe wider than the ' rest and 

 terminating at the base of the caudal horn; the latter at an angle of 20°, 

 recurved backwards, purplish red and thickly granulated ; the anal plate with
