A TORTOISE-BEETLE NEW TO QUEBEC 



BY THE REV. THOS. W. FYLES, LEVIS, P. Q. 



In July last I noticed that the leaves of the burdocks on the Heights 

 of Levis were riddled as if from a discharge of small shot. On 

 examination, I found that the damage to the leaves was caused by 

 numerous latvae of a species of Cassida. The creatures were there in 

 strength, each supporting, by means of the forked prolongation of its anal 

 segment, its " stercoraceous parasol." Towards the end of the month 

 the grim-looking pupae were to be seen, bristling round their edges 

 with white branched spines, and attached to the leaves by a natural 

 cement. In the present month (August) the beetles have appeared. 

 They are about eight millimetres in length and five millimetres in breadth. 

 The elytra and the thoracic shield are pea-green and are closely indented.
