the base of the thorax above. The wing-covers have 

 seven narrow longitudinal elevations, with two rows of 

 dots between them. Its piercer is folded under the 

 thorax when not in use. It feeds on the quince both in 

 the larva and imago, burying itself entirely in the fruit. 

 Occasionally it attacks the pear. 



In May the beetles come from the chrysalids, pair, and 

 commence laying their eggs in June. In piercing the 

 fruit they make a cylindrical hole 

 a little larger than the egg, and 

 enlarged at the base. In this 

 the egg is laid, and hatches in 

 a few days. The larva burrows 

 through the growing fruit near 

 the surface, seldom penetrating to

opening, after which it buries itself in the earth two

 Remedies. Jarring the beetles off the trees on sheets 

 and killing them, if thoroughly done, will prove effective. 

 Gathering and destroying the fruit that falls, or that 

 which does not fall if it has been stung, will be helpful in 

 destroying them. 



There are several caterpillars besides those named that 

 prey on the leaves of the quince, which we have not yet 

 been able to name with certainty. One is a large and 

 nearly black caterpillar ; and another is small, and mot- 

 tled like some of the span worms.
