LEAF-BEETLES. 3 43 



The larvffi are all small white grubs infesting the roots and 

 crowns of the strawberry plants, eating the smaller roots, and 

 penetrating and mining the interior of the crown and main root. 

 These larv?e possess well developed legs, while the genuine 

 "strawberry root-borer" described later has no legs at all. The

 strawberries than to the cultivated ones. 



Synopsis of larvae. 



I. ]\landibles bitid at tip. 



A. Inner edge of mandibles excavated before tip, 

 anal segments shorter than preceding, ventral 

 tubercles not prominent Paria. 



B. Inner edge of mandibles not excavated, anal 

 segments more developed than preceding, ven- 

 tral tubercles prominent, with long hairs Colaspis. 



II. ^Mandibles entire at tip, inner edge excavated, anal 



segment short, ventral tubercles not prominent. .Gra/'/io/>^\ 



Synopsis of piipac. 



I. Anal hooks simple, incurved Colaspis. 



II. Anal hooks recurved. 



A. Hooks short and stout, with strong erect tooth 

 at upper side of base, and two long hairs on 

 posterior margin Graphops. 



B. Hooks slighter, simple, or with slender hair at 

 upper side of base, no hairs on margin Paria. 



"The three beetles mentioned above may be easily distin- 

 guished, the Colaspis being usually of a pale clay-yellow, ranging 

 to a yellowish brown, smooth but not shining, concolorous 

 throughout, or occasionally with the head and thorax green ; while 

 Paria is shiny black above, varying to brown, with four black 

 blotches upon the wing-covers, but always with pale legs (and
