in all fruit districts visited in ^Missouri. It is known to occur over 

 the United States, from the sea-coast to above tim])er-line on the high- 

 est mountains of the Rockies in Colorado. It ranges south into j\Iex- 

 ico and north far into Canada. It is one of the well known insects 

 of Europe, having first been described by Linnaeus in 1767 and again 

 under another name by Palisot de Beauvois in France from insects 

 collected in Africa and America. It was first brought to the notice 

 of American entomologists by Thomas Say in 1831 and mentioned as 

 an injurious insect by Harris in 1841. It is mentioned as an economic 

 pest by Riley, Walsh, LeBaron, Cooke, Glover, Saunders and Lugger 

 and has at some time or other been included in the reports of nearly 

 every leading entomologist in the country. 



So far as the writer is aware this record is the first of oviposition 

 of the insect in apples, or in fact in any fruit. Professor Woodworth 

 states that the egg of this insect was not known at all until 1884 when 

 Doctor Forbes, after a protracted search, succeeded in finding a single 

 specimen among the hairs of the petiole of a dead strawberry leaf, and 

 Professor Slingerland is reported to have found their eggs in blighted 

 peach twigs in New York. 



It was no small satisfaction to the writer to be a])le to accurately 

 identify these egg-pits this fall upon apples in experimental blocks, 

 very successfully treated for the control of curculio and codling-moth. 

 Without this knowledge I should have been led to classify the injuries 

 as the very early food punctures of the apple curculio {Anthonomus 

 quadrigihbus Sa^O. or even the early food punctures of the plum 

 curculio (Co)iotrackelus nenuphar Ilbst.). It seems possible that 

 failures, or at least only partial successful results, which have been 

 reported in the control of curculio upon apples with arsenical sprays, 

 has been due to this mistaken identity of injuries. 



Remedies or preventive measures will not be discussed in this ar- 

 ticle, but it has been observed by the writer that orchards where clean 

 cultivation is practised and where a minimum number of adults are 

 permitted to hibernate through the winter suffer least from spring 

 oviposition in the fruit. 



The photographs reproduced herewith show the egg-pits from the 

 tarnished plant-bug in Ingram apples in their various stages of 

 growth. Fig 1, Plate 10, in which the size of the apples is reduced 

 about one half, shows the dei)ressions upon apples when very small, 

 still coated with pubescence and less than a month after the hatching 

 of the plant-bug eggs. Fig. 2. Plate 10, shows apples of about one 

 third size, about two months from egg hatching. These well illus- 

 trate the depressions which may be appropriately spoken of as ''dim-
