ings were few and confined to the early part of his life, his 

 knowledge of Aphids was remarkable and his unselfishness in 

 sharing this knowledge with his co-workers and his good-na- 

 tured willingness to help anyone and everyone who applied to 

 him for aid, places him high as a scientist. Besides the papers 

 listed below, Monell contributed short items to most of the 

 early American entomological publications and he has, be- 

 cause of his willingness to share his knowledge with others, 

 become a contributor to many of the important papers on Aph- 

 ididae. As Professor F. M. Webster has so aptly said, "Ento- 

 mology has certainly sustained a serious loss as he seemed to 

 have an inexhaustible fund of knowledge which he was always 

 ready to impart freely to anyone whom he could assist in any 

 way." 



In 1914 Mr. Monell suffered a stroke of paralysis, and, six 

 months later, a second stroke left his entire lower limbs help- 

 less, although his arms and brain were perfectly normal for 

 he mounted a slide of Aphids as late as April, 191 5. Asthma, 

 brought on from hardening of the arteries, caused his death. 



He married Nellie Gifhorn September 30, 1881, who sur- 

 vives him, and who bore him five children, of whom three, all 

 of St. Louis, survive him. 



The Monell collection of Aphididae, which contains most 

 of the American species, as well as many types — all on slides 

 in balsam — and his complete notes on most of the mounts 

 in the collection, will eventually be deposited in the United 

 States National Museum. 



Monell published the following entomological papers, de- 

 scribing one new genus and 32 new species: 



A new genus of Aphididae. (Can. Bnt., Vol. 9, No. 6, June, 

 1877, pp. 102-103. Reprinted in The Valley Naturalist, Vol. 

 I, No. I, Jan. 1878, p. 2.) 



Describes Colopha nov. gen., giving C. ulmicola Fitch as type spe- 

 cies, and straightens out the generic tangle. 



A new species of Lachnus. {The Valley Naturalist, Vol. i. 

 No. 6, June, 1878. p. 21.)
