Food plant: Not known. Type specimens in the collec- 

 tion of Mr. O. Jacobsen. The author takes great plea- 

 sure in dedicating this species to its discoverer, who has 

 been exceedingly successful in exploring the Danish 

 Hemipterous Fauna. 



As only one pair of the species is known hitherto, 

 the author did not regard it advisable to dissect the spe- 

 cimens for further examination. It is hoped that more 

 specimens may be found later on, so that, for an instance, 

 the shape of the genital styles of the male may be fully 

 described and delineated.
