The specimens observed by these writers were obtained at Kansai 
City Missouri; and the strawberry plants on which they occurred 
had ’been received from Palmyra, New York and bouth Bend, Indi- 
ana, from which places the species was probably imported. 
The appearance of a plant-louse upon the strawberry onjMj 
opposite side of the continent, was reported in the Pacific hural 
Press” for May 15, 1880, the editor of that paper expressing the 
opinion that plants infested like those sent him would lose then- 
vigor, and produce poor fruit, even if the plant were not utteily 
ruined. _ . < 
In a paper on Insects Affecting the Strawberry,* I gave, in 1883, a figure 
of a plant-louse and its egg, found upon the crowns of strawberry 
plants in Central and Southern Illinois in autumn; referring Ins, 
provisionally, to Siphonophora fragana, Koch, but saying in a foot¬ 
note “The form figured above, from Southern Illinois, has the 
aspect of an Aphis, and it is possible that the Illinois species is no 
Siphonophora frag aria, as was supposed by Dr. Thomas. I ntil the 
aerial forms can be seen, however, I prefer to leave the matter as 
above.” 
Mention of the occurrence of plant-lice upon the s . tra wberry m 
Europe was made by Walker, in 1852, and by Koch m 1855, both 
referring to the species already mentioned. 
In 1861 Passerinit announced two other species upon tlie straw¬ 
berry in Italy, Aphis chloris, Koch, and a root-louse, Rhizobm 
sonchi, upon the roots. 
In his work upon British Aphides, published m 1876, Buckton 
gives a full description of the pupa and the winged and wingless 
female forms of Siphonophora fragaricz, and mentions likewise its oc¬ 
currence on the strawberry in England m 1876, upon the stalks of 
the unripe fruit.
