than 1888," from Alameda County. One other broker gives 1893 as 
the first elate infested beans were observed by him from the same lo- 
cality. Mr. E. A. Bunker, from a personal transaction in 1898, posi- 
tively remembers that date as the first year infested horse beans were 
observed by him. Other dates for the different localities given by 
different bean brokers are as follows: Gilroy, 1890; "Watsonville, 
1900: Morro. 1900; Oceano, 1903; Halfmoon, 1904; and Sacramento, 
1908. 
It must be remembered that in none of the above dates were the 
weevils in horse beans identified as Bruclius mifinwnus, but there is 
little doubt that this is what they were. It is, therefore, quite evi- 
dent that the insect was present in the different localities a number 
of years before September, 1909. 
DISTRIBUTION IN CALIFORNIA. 
The principal broad-bean sections in California are around San 
Francisco Bay and down along the coast to a little below San Luis 
Obispo. The insect is distributed all over this section, having been 
taken or reported from the following counties : Sonoma, Xapa, Yolo, 
Sacramento, San Joaquin, San Mateo, Alameda, Santa Cruz, Santa 
Clara, San Benito, Monterey, and San Luis Obispo (fig. -1). Broad 
beans are grown in small quantities in many other counties, usually in 
back yard gardens or in small plots for the green beans. Of late years, 
in several counties, they have been quite extensively planted as cover 
crops, particularly in citrus orchards. Unless great care is exercised, 
which is not often done, in planting uninfested or treated seed, it is 
safe to say that the broad-bean weevil will be found wherever broad 
beans are grown and allowed to come to maturity. The writer has 
found eggs on the green pods of broad beans planted for cover crops 
in Los Angeles, Orange, and Riverside counties. Cover crops, how- 
ever, are all plowed under before the weevil has had a chance to 
develop. 
SPREAD IN CALIFORNIA. 
The broad-bean weevil probably became established in Alameda 
County, where horse beans were first grown, about 1888. It next 
appeared in Santa Clara County in 1890. and in Santa Cruz, Santa 
Clara, and San Luis Obispo Counties in 1900. By 1904 it was 
reported from San Mateo County; by 1911 from Sacramento and 
Sonoma, by 1911 from Yolo and San Benito, by 1916 from San 
Joaquin, and by 1917 from Xapa. 
DISSEMINATION. 
Although the adult insect is an active creature and doubtless can 
fly some little distance, from one field to another, or from where 
beans may be stored to a near-by field, the principal method of dis-
