FAMILY MELOLONTHIDiE. 79 



The roscbiig, or c/ierrybug, as it is called, is very destructive. Its geuerie name Macro- 

 dad 1/ 1 us, is dnival from the length of the feet ; and its specific or trivial name subiiAnaus, 

 from an incipient sj)ine or swelling; upon the sides of the prothorax. It is of a dull jtllow 

 color, about three eighths of an inch Ions, and ajijuars in great abundance in the spring, 

 destroying roses and the blossoms of various plants, as well as the foliage of Iruit trees, 

 uicluding the apple, cherry, plum, and that of the grajie. 



Dr. Hakris has the cretlit of being the lirst to give a satisfactory history of this insect, 

 as published in his Report. 



I have been in the habit of destroy ing this insect, as well as the Erivscma malt, or the 

 applcirce blig/il, by hand-crushing. When there is little or no grass beneath the trees, they 

 may be beaten down and crushed with the foot ; the best time being the morning, v^hen 

 they are somewhat torpid. They may be cullectcd upon sheets, or in vessels with a little 

 water to prevent their escape ; to be subsequently burned or scalded. Plants infested should 

 be visited once or twice a day, and every eflort made, by destruction of the i)resent brood, 

 to diminish that of the next season. 



Genus CETONIA ( Fab.). 

 Anteuuje short, the basal joint largest and rolmst, glalirous ; the bcatl three-leaved, elon- 

 gated : palpi short, last joint eylindric tapering; mandibles short ; clypeus quadrate, 

 entire in front ; thorax subtrigonal ; elytra sinuate at the outer margin near the base ; 

 scutellum elongate and acute ; sternum produced and rounded anteriorly. 



Cetonia i.nda. Scarabaus i«rfu*(Lin.). ( Plate xii, lig. G.) 



Body ovate and rather depressed, pilose above and beneath. Clypeus deflexcd and trun- 

 cate : thorax subtriangular-, sinuate before, centre of the sinus subdentate, broadly 

 sinuate jiehiiid lor the reception of the sciitel ; scutel an isosceles triangle : elytra 

 light bi\>wn with black spots sc<ittered over their disks and sides, margins sinuate, 

 behind truncate, exposing the alulomen ; legs hairy and brown ; abtiomen brown, 

 glossy. 

 The thorax is more densely clotlied with hairs than the elytra ; th<- latter are sprinkled 

 with spots and dotswhich are nearly Idack, some angular, and others sinuate. Color of the 

 abdomen and legs nearly uniform : the thorax is also spotted Ix-neath the hairs ; the 

 sinuated base is naked and fuscous. Length six-tenths of an inch. 



This insert apjjears twice in the season ; first in March or April, and last in Septcml'cr : 

 the latter, as Dr. Hakkis supposes, is a newly hatched brood, as at no time during the 

 summer is an individual to be found. 



These insects appear upon various autumnal flowers, as the goldcnrod, in search of 

 pollen and honey, and arc fond of the sap and sweet juices of trees and plants. Ihey are
