266 JASSID^. 



the classification of the Jassinae is still a matter of expert opinion 

 and the last word has not yet been said on the subject. In this 

 publication the system adopted is not regarded as of the first 

 importance, so long as it enables those for whom the book is 

 written to readily recognize the genera and species described or 

 enumerated. 



As regards the generic descriptions I have in many, if not in 

 most, cases reproduced the diagnosis of the founders of these genera, 

 and although many new- ones have had to be proposed it is probable 

 that strictly following the method pursued more generic sub- 

 division is necessary. There are, however, so many described 

 species which I have not seen, that such a course becomes 

 impossible. 



I have to acknowledge with gratitude the great help I have 

 received from Mr. E. P. Van Duzee of Buffalo, N.T,, who has 

 sent me many Nearctic specimens identified by himself, and as the 

 genera of Jassiuse are widely distributed the assistance thus 

 rendered has been considerable. Dr. Horvuth of Budapest has 

 again kindly let me see such of Melichar's types or cotypes as are 

 contained in the Museum Hongrois. Walker's types in the 

 British Museum have been at my disposal and also the large 

 collections made for me by the late Mr. Doherty in India, Burma, 

 and Teuasserim. I have also seen the specimens belonging to the 

 Indian Museum at Calcutta, frequently supplemented by others 

 collected by its enthusiastic superintendent, Dr. Annandale. Erom 

 Mr. Maxwell Lefroy I have received much material from Pusa. 

 Finally the immense assistance already rendered by Mr. E. E. 

 Green of Ceylon has been supplemented by his particular effort to 

 procure me Jassid representatives from that island.

Genus UZELINA. 

 Uzelina, Melich. Horn. Faun. Ceylon, p. 181 (1903). 



Type, U. laticejjs, Melich. 



Distribution. Ceylon. 



" Vertex as broad as pronotum, in front broadly rounded, above 

 arched, the surface curved downward with two ocelli on the disk ; 

 face broad, directed downward, almost concave ; pronotum in front 

 broadly rounded, behind straight ; scutellum half as long as pro- 

 notum with an impressed line in the middle ; tegmina somewhat 

 passing abdominal apex, rounded behind, the outer sector forked, 

 the inner forked branch connected with second sector by a trans- 

 verse vein, both in middle and apical areas a row of transverse 

 veins, membranal appendage narrow ; legs simple. The broad 

 downwardly curved head, which looks as if it was excavate on 

 lower side, is a characteristic feature." {MeJichar.)
