The " hickory girdler," O. cingu/afus, Say (fig. 4), 

 is the only Canadian species. It is variable in colour, 

 but the northern forms will approximate the following 

 description : Brownish or reddish yellow, prothoracic 

 spine blunt or wanting ; elytra with a broad transverse 

 band of (usually) cinereous pubescence and with 

 scattered yellow spots, these latter sometimes forming 

 tolerably regular rows. Length, .56-68 in. Dr. 

 Hamilton says that it occasionally girdles pear, apple, 

 plum, linden, elm, and various other trees. 



Amphionycha, Lee. ' ' 



A. flanimata, Newm., is .24-38 in. long, black, clothed with erect 

 dark hairs, the head with two yellow spots or stripes ; the sides of the 

 thorax are broadly, those of the elytra (usually nearly to tip) narrowly, 

 yellow. The elytral punctuation is very close and coarse. Antennae 

 clothed with long hairs. Care should be taken not to mix this species 

 with Eupogon'ms stibarinatus, which it very closely resembles. 



Saperda, Fabr. 



All of the North American species have been found in Canada, so 

 we reproduce entire the table given by Dr. Hamilton in Trans. Am. Ent.
