This species is the sinuate pear borer. Eggs are deposited in crevices and 

 under flakes of bark, and the resulting slender, whitish larvae construct narrow 

 winding burrows in the sap wood, the courses of these channels being indi- 

 cated exteriorly b\' the discoloured and abnormal bark over them. On young 

 trees this discoloured bark splits or raises into a welt.
