THE AUSTRALIAN APPLE LEAFHOPPER, 



rounded anteriorly and slightly excavated .posteriori}'. Scutellum slightly nar- 

 rower at base than base of head including eyes. 



Ovipositor shining mahogany brown. 



Length (with folded tegmina) 4 mm. 



In New Zealand it is found in the Nelson and Auckland fruit districts 

 (November to March), where it inflicts considerable damage on the foliage of 

 apple and hawthorn. The signs of its attack are rusty spots and patches on 

 both sides of young and old leaves, particularly the latter. 



Mr. F. Muir, of Honolulu, has very kindly furnished me with drawings of 

 the aedeag-us of allied Australian Eupterygines and of the European and N. 



a. 



(All figures drawu by V. Muir, K.E.S., Honolulu).

American Typhlocyba (Empoa) rosae Linn. As will be readily seen these in- 

 dicate clearly the points of distincti(m between the species under discussion and 

 those described by Kirkaldy. 



Mr. Muir, hj whom specimens were submitted l)y Dr. K. .T. Tiliyard, who 

 hiLS kindly placed all notes in my hands, is unable to identity 'I\ mt-stralis with 

 any American or European sjjccies; but he nevertlieless considers it possibly an 

 importation into Australia. Until records however are forthcoming of its oc- 

 currence in other countries we are justified in considering it distinct. Good 

 figures of the imago, nymph, tegmen, wing and injury to apple foliage are 

 given by Froggatt in his original paper.
