LiBURNiA PULLULA, Boh. Plate XIV., figs. 4, 5. 



Delphax pulhda, Boh.; Stal; Fieb., G. D. t. 8, fig. 39. 

 Lihurnia pullula, Scott; Sahib.; Fieb., C. E. pt. iv. 

 42 ; Edw. pt. i. 75. 



Very small. General colour dirty ochreous-yellow. 

 Head round in front, with a brownish vertex. Eyes 

 black. Pronotum and scutellum together about one- 

 third longer than the head. Abdomen short, conical, 

 and ringed, with an obtuse pygofer, and long oval 

 aperture containing short black styles, and a deltoid 

 anal opening. Elytra very short, ovoid, and of a 

 brown colour, marked by coarse dark nervures. Legs 

 and antennae pale ochreous. 



I have not met with the Macropterous male, but it 

 is described as having the pronotum with side keels 

 distinct and curved outwards ; elytra two-thirds longer 

 than the abdomen, with yellow, sparingly granulated, 

 nervures. Habitats: — Sweden, Germany, and Swit- 

 zerland. 



L. pullula differs from L. forcipata in being much 

 smaller, in the different shape of its abdomen, in its 

 dark instead of yellow pygofer, and its shorter styles. 

 Fieber says : — " Tube anal preeminent de moitie, noir, 

 presque lamellaire vers le has, avec deux crochets verti- 

 caux, accoles, atteignant presque avec leurs pointes 

 incourbees et rousatres, la demi-hauteur de la cavite 

 du pygophore." 



Size, 0-06 X 0-04 inch or 1-52 x 1-01 millimetres.
