Mr. J. R. Parker: I might say we found both long- and short¬ 
winged forms. 
Mr. E. D. Ball: That sounds rather suspicious. 
Mr. J. R. Parker: We found these at an elevation of 2,087 feet. 
Dr. L. 0. Howard: When did you send your specimens to Mon- 
tandon? Before the war? 
Mr. E. D. Ball: Ten years before the war. 
Mr. Cotnam: Our main method of control in Kansas is based 
upon the hibernation of the bug. Since 1910 we have examined hun¬ 
dreds of grasses and found that they go into hibernation, but we have 
never found them after the middle of December. We do find that in 
Kansas we have a variation of the hibernation and a variation in the 
appearance. Sometimes the bugs leave hibernation in March and 
are found early in the spring. In other years, the bugs do not leave 
hibernation until May.

Scientific Notes 
A Predaceous Enemy of Bean Weevils. While watching a bean weevil (Bruchus 
quadrimaculatus Fab., ovipositing, in June, 1919, the writer became convinced that 
there was something abnormal about its actions. After the weevil had deposited each 
of four eggs, it stroked its elytra with its hind legs; rapidly whipped its antennae back 
and forth; tried to bite its fore tibiae; extended its head as far as possible beneath its 
body; tried to roll over and then extended its wings as if to fly; closed them up and ran 
rapidly about, stopping frequently to scratch at its mouth. It tumbled about in a 
most excited manner. Examination showed a tiny mite attached to its labium. 
The abnormal movements were undoubtedly efforts to rid itself of the intruder. 
At that time the weevil did not enlist the sympathies of the writer but it rather gave 
him satisfaction to see how its enemies were after it. Later, however, his sympathies 
were with the weevil because of the torture it was forced to bear. 
Although numerous eggs were deposited on the beans in this container, careful 
observations showed that only a few adult weevils emerged from them. Upon open¬ 
ing the beans several dead larvae and pupae were found together with numerous 
large round masses which proved to be gravid female mites. Several of the latter were 
put into a jar of black-eyed cowpeas from which many weevils were emerging. While 
the actions of the weevils showed that the mites were busy, several hundred eggs were 
deposited before the last weevil died. 
When the dead weevils were removed from the jar many were carrying gravid 
female mites protruding from under their wings. The following day the writer broke 
out with a case of “small-pox,” this being the best description for the many pustules on 
his arms and body. Some days later, after again handling the mites, he experienced a
