by a jury, and fined $150 (9)1 Sinc6 then many dealers have refused 

 to handle horse beans, while those who continued to deal in them 

 have had to exercise caution that no shipment contained more than 

 15 per cent' infested beans, or else run the risk of confiscation. The 

 numerous confiscations during the past few years of shipments in 

 transit by food inspectors, and the cost of hand picking to keep the 

 infestation within the 15 per cent permitted, has resulted in keep- 

 ing the price of beans low and reducing the acreage. 



Although the bean is commonly called the horse bean, the name is 

 somewhat a misnomer, as only about 30 or 40 per cent of the crop 

 is used as stock feed. The larger portion is shipped to New York 

 and other eastern cities, where it is used for food by Italians and 

 Portuguese, and is known as fava. Other names are English bean, 

 Windsor bean, and tick bean. 



The horse bean is used also as a green vegetable, and of late years 

 has been planteel to a considerable extent as a winter cover crop, 

 especially in fruit orchards. A recent Farmers' 

 X '« /, Bulletin (8) recommends further plantings along 



the Pacific coast, the Gulf of Mexico, and the South 

 Atlantic States, not only for the dry beans for 

 human consumption, but also for the green vege- 

 table, stock feed, and green manuring. 



DESCRIPTION. 



THE EGG. 



i 



Fig. 1. — The broad- 

 bean weevil : Egg. 

 Greatly en- 

 larged. (Chitten- 

 den.) 



The egg (fig. 1) is elliptical-ovate, about twice as 

 long as wide, a trifle more pointed anteriorly, its 

 surface smooth with no visible sculpture. When 

 first laid it is whitish and glistening, but gradually 



turns darker. Just before hatching, the black head of the embryo can 



be seen plainly through the shell. 



THE LARVA. 



The young larva is pale yellow, with dark or black head and mouth- 

 parts. The full-grown larva is cream colored, with small brown head 

 and black mouth-parts. It is 4.5 to 5.5 mm. long and 2.5 to 3 mm. 

 wide. 



THE PUPA. 



The pupa when first formed is light yellow or cream colored, with 

 legs and wing-covers whiter. It gradually turns darker, particularly 

 the appendages, until it is light brown before transforming. It 

 measures about 3 mm. wide and 5 mm. long.
