able with the first generation upon beans. In a letter of September 
6, 1897, Mr. Weed states, in answer to the writer’s Inquiry, that the 
species is probably three. brooded in his State, and that he has noticed 
the beetles very numerous in September and October on cowpeas. 
At present the periods of development can only be conjectured. From 
analogy and the crude data available it may be surmised for the lati- 
tude of the District of Columbia that the parent beetles begin oviposi- 
tion upon their appearance, about the middle of May, continuing prob- 
ably through the month of June. The eggs hatch in from five to eight 
days, the larve complete their growth in from four to six or seven 
weeks, and the pupa state lasts from five to eight days, all these periods 
varying with the conditions of heat, dryness, or moisture. The entire 
life cycle would in the same manner require from six to nine weeks. 
Individuals obtained August 2 to 16, undoubtedly of the new generation 
from their fresh appearance and plump, round abdomens, laid eggs at 
this time, indicating a second generation. Farther northward in the 
transition zone we would expect only a single generation annually. 
REMEDIES. 
At present this species, although of apparently very common occur- 
rence on beans in the upper austral regions about the District of 
Columbia, can not be regarded as a first-class pest here, and has not yet 
justified any elaborate experimentation with remedies or preventives. 
As the species is more injurious southward, however, some suggestions 
looking to its suppression may be made. 
The sluggishness of the beetles indicates hand-picking as of value in 
small gardens in cases of excessive abundance early in the season. 
The beetles occur rather more numerously on the under surface of 
the leaves than above, and a thorough spraying, particularly an under- 
spraying, with the arsenicals will destroy them. This remedy should 
also be employed upon the first appearance of the insects in order to 
stop them at the very outset and to avoid possible poisouing of the 
bean pods if these are to be eaten green. 
Professor Popenoe is authority for the statement that pyrethrum 
‘puffed over the plants in ordinary weather is a measurable check to 
the work of the insects.” 
More important than any other measure is clean culture and the 
careful weeding out of the wild food plants in the immediate neighbor- 
hood of the cultivated ones. Tick-trefoil is a pest in itself, so this 
should operate as an additional incentive for its eradication.
