fcuir conspicuous brownish-red humps towards the hinder part 

 of its body, from which it takes its specific name, quadriggibus. 

 Inchiding the snout, its length is a quarter of an inch or more. 

 In the accompanying iUustration (Fig. 209), the insect is mag- 

 nified ; a represents a back view, b a side view ; tlie outHne at the 

 left shows its natural size. Its body is dull brown, shaded with 

 rusty red ; the thorax and anterior third of the wing-covers are 

 grayish. 



"This is a native American insect which formerly bred exclu- 

 sively in the wild crabs and haws ; it is single-brooded, and passes 

 the winter in the beetle state. The beetle appears quite early,

and the larva may often be found hatched before the middle of 

 June, and in various stages of its growth in the fruit during June, 

 July, and August. 



"The beetle with its long snout drills holes into the young 

 apples, much like the puncture of a hot needle, the hole being 

 round, and surrounded by a blackish margin. Those which are 

 drilled by the insect when feeding are about one-tenth of an inch 

 deep, and scooped out broadly at the bottom ; those which the 

 female makes for her eggs are scooped out still more broadly, and 

 the egg is placed at the bottom. The tgg is of a yellowish color, 

 and in shape a long oval, being about one-twenty-fifth of an inch 

 in length and not quite half that in width. As soon as the larva 

 hatches, it burrows to the heart of the fruit, where it feeds around 

 the core, which becomes partly filled with rusty-red excrement.
