REPORT OF STATE ENTOMOLOGIST, 1898 159 



LeConte and Horn (see citation) state that but one species, obviously 

 B. unicolor, occurs in the Atlantic district. The present record indicates 

 that it is pretty well distributed over the eastern United States and 

 extends north into Canada. 



Description. The beetles are about y inch long, subcylindric, and 

 of a pale reddish brown color. With a lens, the dense, rather long 

 pale, tawny hairs covering the entire upper surface are easily distin- 

 guished; the vestiture of the under surface is shorter. 



The larva has been described by Dr Fitch as follows : 



When examined with a magnifying glass, these worms are found to be 

 plump and cylindric, slightly tapered at each end, and nearly \ inch 

 in length when fully grown. They are white, each segment having on 

 the back a broad, pale, tawny yellow band occupying more than half its 

 surface, and being also furnished with a few short, erect, whitish hairs. 

 The mouth is darker, tawny yellow. On the breast are three pairs of 

 legs, but none on the body back of these, except at the tip, which is 

 prolonged into a single proleg of a short conic form, and blunt at its 

 end ; and on the apex of the last segment, above the base of the proleg, 

 are two minute projecting points, appearing like two deep red dots. 



Life history. The beetles occur on the raspberries the latter part of 

 May, and in Massachusetts till after the middle of June, as stated by 

 Dr Packard. The eggs are probably laid on the developing fruit, as is 

 recorded by Miss Ormerod of the related B. tomentosus. The following 

 notes on its life history are based on records by Dr Fitch. The larvae 

 are usually found lying on the inner side of the cup or cavity in the 

 berry. When full grown they drop to the ground or fall with the fruit 

 and transform to pale, dull, yellowish pupae under leaves or other rub- 

 bish, where they remain till the following May. Miss Ormerod states 

 that B. tomentosus pupates under the sheltering bark of the raspberry or 

 in some similar place. It is possible that our species also pupates to 

 some extent on the canes. 



Remedies. The beetles can probably be controlled by spraying 

 with an arsenite. Hand picking or beating them from the bushes into 

 pans containing water and a little kerosene, has also been recommended. 

 The latter will be more effective if done in the cooler part of the day, as 

 the beetles will be less likely to take flight. There are no effective 

 means of dealing with the larvae. If the insect becomes numerous in a 

 patch, it might be advisable to burn all the trimmings and rubbish, in 

 order to destroy as many of the hibernating individuals as possible.
