Some new Delphacinæ from 

 Denmark. (Hem. Horn.). 



By 

 A. C. Jensen-Haarup, Silkeborg. 



Extensive researches in the Danish Homoptera by 

 iMr. O. Jacobsen, Copenhagen, brought the unexpected 

 results that several species new to science have been dis- 

 covered; one of them even constitutes a new genus near 

 Liburnia. 



The following lines will describe the new genus and 

 two new species, and repeat the description of a third 

 species, which has just been published. 



Paraliburnia n. gen. 

 J. Genital segment very peculiar, seen from below 

 oviform (see fig. 1 a); cavity (apertiira postica) below 

 the very wide excavation around the anal tube small and 

 narrow, downwardly acute-angled, almost cuneiform (with 

 somewhat flexed sides); the pointed end of the cavity 

 very far from base of the segment. Genital styles (styli 

 genitales) except the very tips of them — in the geno- 

 type — involved and quite hidden under the confluent 

 and united sides of the segment, as seen from the figure. 

 Last dorsal segment of abdomen (in casu genital segment) 

 without distinct excavation for the transversally very wide 

 and large anal tube (tuba analis). Anal style (stylus 

 analis) long and stout, somewhat hairy.
