CG NATURAL HISTORY OF GLOSSINA PALPALIS 



Thou'i't gnawed to death by cruel starvation's fangs ! 



Yet do I wish for thee severer pangs 



Since none of the above are adequate 



Or quite sufficient to express my hate ! 



May Bembex wasps (those skilful hunters) thrust 



Into thy side the lancets which, I trust. 



Will fail to paralyse thy sense of pain 



While rendering thee inert, that sod, in vain 



Thou strivest to escape from htmgry jaws 



Of Bembex' child, devouring without pause 



Thy non-essential tissues ; till, at length 



When it shall have attained its perfect strength. 



Thy shrinking vitals are devoured by it. 



And there is left of thee no little bit 



AVhereof a man might say, '' This was a FLY, 



A noble creature that knew how to die " ! 



So that there shall not e'en be left of thee , 



So vain a thing as a fond memory ! 



Thus would I wreak my vengeance on thee, pest. 

 That oft hath bitten me with fiendish zest ! 



Addendum. 



The first observations on the use of artificial breeding 

 places were made in 1914, but were interrupted by the 

 war. 



During the war my friend, Dr. W. A. Lamborn, in 

 Nyasaland, unknown to me, was experimenting on his 

 own lines by cutting down trees to make artificial breeding 

 I)laces for G. morsitans. (See Bulletin of Entomological 

 Research, May, 1916, VII, p. 38.) This method had been 

 developed by him independently, for my re]3ort, delayed 

 in publication by the war, was not pubhshed until 1919. 

 (See Reports of the Sleeping Sickness Commission of the 

 Royal Society, 1919, No. XVII, pp. 67-71.) I did not 

 hear of Dr. Lamborn' s work until after I had been 

 able to develop and make first use of my scheme early 

 in 1919.
