EUPTERYX CARPINI. 125 



My figures are from specimens in Mr. Douglas's 

 cabinet, two out of five of wliich are noted as feeding 

 on tlie mullein (Verhascum). They are labelled 

 Eupteryx picta, Fab., and have also the synonymn 

 E. punctata, Goetz. 



Although the hornbeam {Carpiiius hetidus) is suffi- 

 ciently common at Haslemere, I have not taken the 

 above insect under its shelter.

Mr. Whitehead says that Typldocyha picta, or the 

 hop-jumper, much weakens the hop-plants by boring 

 holes in the leaves and bines, and sucking their 

 juices. 



I presume this insect is equivalent to one of the 

 above-given synonyms of E. carpini. J. Curtis says it 

 also affects the burdock and the nettle. When injury 

 is thus done to the hop-plant, the use of boards 

 smeared with tar and held towards the vines are recom- 

 mended, whilst the plants are shaken. " The tar will 

 entangle great numbers"; but on a large scale it is 

 doubtful if much benefit can be had by such a pro- 

 cedure. A thunder shower would be far more effi- 

 cacious, but science and meteorology cannot yet com- 

 mand such service from the clouds. 



Curtis first observed this insect in 1847. He noticed 

 them upon his potatoes in the middle of June, and by 

 August he found them greatly increased in numbers, 

 although the foliage of the plants was still green and 

 healthy. When disturbed they flew at about one foot 

 from the ground, but they soon returned to the under 

 sides of the leaves for shelter. 



A good figure, and sufficient for identification, 

 although the colouring is too green, is on Plate 0, 

 figs. 32, p. 473, of J. Curtis's ' Farm Insects.' 1860.
