The Rose Chafer. (Cal.) 



[MacrodadyluH subspinusus. — Fabr. ) 



Order, Coleoptera ; Family, SrARAB.Ti:iD^. 



[Feeding upon the leaves of the grape, rose, apple, cherry, 



etc. ; a slender brownish-yellow beetle, about four lines long.] 



This insect is a very general feeder, and at times becomes 



very injurious. During its larva stage it lives in the ground, 



feeding upon the roots of various kinds of plants. 



The eggs laid by each female are about thirty in number, 

 and are deposited from one to four inches below the surface of 

 the earth. 



The larva? lie upon their sides, their bodies being curved so 

 that the head and tail nearly meet each other. They are of a 

 yellowish-white color, with the head pale reddish. They pass 

 the Winter in their earthen cells, and assume the pupa form 

 the following Spring, there being but one annual brood.

 The beetles, or chafers (Fig. 180), as they are com- 

 monly called, measure about four lines in length ; 

 the thorax is produced into a small point on each 

 side of the middle ; the head and thorax are black, 

 and the wing-cases brown, but the entire insect is 

 colored with yellowish scales which give it a brownish-yellow 

 appearance.
