FULLER S ROSE BEETLE: ITS TRANSFORMATIONS. 



M3 



United States from the seaboard to the Pacific ocean, and from Canada. 

 Its greatest injury is committed upon roses grown under glass, by the 

 larvre feeding upon the tender rootlets — at first merely checking their 

 growth, but finally, when their numbers have increased, destroying the 

 plant. It has also been observed upon the roots of Gera7iium and 

 Hibiscus, and in California, is reported as " very destructive to Draccenas 

 (and palms lightly), oranges, cape jessamine \Oarclcnia\, and Achy- 

 ranthes, in the order named." In Brantford, Canada, it has been found 

 upon Abiitilon and Plimibafio in hot-houses. From Massachusetts, it is 

 reported upon the Azalea, " Cissus," and "inch-plant." 



Transformations of the Insect. 



In the report of the Commissioner of Agriculture for 1878, the insect 

 has been excellently figured in its four stages, and of the first three, 

 scientific description is given. (Fig.35 is from an electrotype obtained from 

 the Department.) From the accompanying account by Prof. Riley, it 



appears that the eggs are 

 laid in clusters of from ten 

 to sixty, arranged in rows, 

 which are artfully secreted 

 between the bark and the 

 trunk of the plant near its 

 base, or occasionally between 

 the ground and the trunk. 

 Upon the hatching of the 

 eggs (c) in about a month, 

 the larvae (a) burrow and 

 begin their feeding upon the 

 rootlets. When fully grown

 foliage and the branches they may be found at rest during the day, as 

 they are nocturnal in their habits, and only leave their concealment 

 after dark for feeding;. 



Description of the Beetle. 



The following is the description of the beetle, as given by Dr. Horn, 

 in The Rliyncho'pliora of America, North of Mexico, loc. cit. : 



Form oblong oval, surface not densely clothed with dark brown 

 scales. Head and rostrum longer than the thorax, densely punctured,
