question of the control of insects which affect goats he is spending some time at the 
laboratories of the Bureau of Entomology at Uvalde, Sonora and Dallas where work 
on insects affecting goats is being carried out. 
Sir Arnold Theiler, Director of Veterinary Research of the Union of South Africa 
toured the United States during the fall. He visited a number of universities and 
experiment stations where he conferred with investigators and delivered a number of 
lectures. He will be remembered among entomologists especially for his research 
on the disease bearing ticks of South Africa. While in Texas he reviewed the 
research work on the loin disease of cattle and confirmed the diagnosis of American 
investigators who considered it identical with lamziekte of South Africa, a disease 
produced by organisms taken in by the stock while chewing bones and not insect 
borne as thought by some. Sir Arnold began his homeward voyage from San 
Francisco during November. 
Squash Pest. Late in the summer of 1921 a coccinellid colony was found completely 
devouring foliage of squash and water melon vines in one garden close to the Mexi¬ 
can boundary and near Douglas, Arizona. In 1922 the insects were found about 10 
miles farther up the Sulfur Springs Valley and attacking all kinds of curcubits it, includ¬ 
ing the native gourd, Apodanthera undulata. In 1923 the range had extended about 
five miles farther. Notes prepared for publication in 1922 were held up pending the 
identification of the species. This has not yet been done to the satisfaction of the 
writer. The entomologists at Phoenix stoutly maintain that the insect is nothing 
more than a variation of the bean beetle. When beans and cucurbits are found grow¬ 
ing immediately adjacent, as at all other times, excepting the cases in which the bean 
beetle exhausts its favorite food plant, the forms on the two . crops are distinctly 
different. The fourteen spotted form has been found invariably on the gourds. As a 
rule it is larger than the bean beetle. During the summer of 1924 it is hoped that an 
opportunity will be afforded the writer to observe this partially dressed “bean beetle” 
in captivity sufficiently long to determine the fixity of the form and to determine 
the possibility of crossing with the sixteen spotted type.
