INJURIOUS AND BENEFICIAL INSECTS OF CALIFORNIA. 317 



outright, or stunted so that the flowers never open. In less serious 

 cases the flowers may open, hut the petals show the holes made in the 

 buds. The leaves are also similarly attacked. Practically all of the 

 injury is done between April loth and May 15th in the interior valleys, 

 but in the higher altitudes the period is about one month later. 



Distribution. — The rose snout-beetle is widely distributed through- 

 out the State. 



Food Plants. — Though primarily a rose pest, attacking wild and 

 cultivated species, this beetle also feeds upon the foliage of grapevines, 

 oaks and raspberries. 



Control. — Jarring the beetles into receptacles of oil or hot water is 

 a very efficient means of controlling the pest in flower gardens. This 

 should be carefully done each day until the adults no longer continue 

 to appear. Poison sprays will also afford some relief, if the attacks are 

 unusually serious.
