230 ARKIV FÖR ZOOLOGI. BAND 1. 



closely and finely punctured in rows near tlie suture, more 

 irregularly and strongly so at the sides, the interstices at 

 the same place transversely wrinkled in both sexes, but very 

 strongly so in the female, near the apex they are slightly 

 longitudinally costate, beside these, fonr narrow raised lon- 

 gitndinal lines can be distinguished, the ground colour is 

 metallic green but the costse. are all of a pnrplish hue, the 

 legs metallic greenish and more or less eeneous, the anterior 

 tibice of the male slightly curved and elongate. 



This is a rather peculiarly marked species, well distin- 

 guished on that account and by the sculpture of the thorax; 

 three specimens were obtained by Prof. Sjöstedt. 



Nisotra Sjöstedti sp. n. 

 Platc 10, fig. 6. 



Fulvous, the apical joints of the antennas black, head 

 impunctate, thorax closely and finely pnnctnred, deeply notched 

 anterior ly, elytra metallic blue, finely geminate punctate- 

 striate, the interstices slightly rugose at the sides. 



Length 4 mill. 



Head strongly convex at the vertex, the latter extremely 

 finely punctured, with a single deep puncture above the eyes, 

 the clypeus rounded above by deep oblique grooves, rather 

 convex, finely punctured, antennas black, the lower five joints 

 fulvous, the second joint scarcely shorter than the following 

 ones; thorax twice as broad as long, the sides feebly rounded, 

 the anterior angles not produced, the anterior margins with 

 a deep perpendicular notch behind the eyes, the surface very 

 finely and closely punctured, scutellum small, fulvous; elytra 

 oblong, more strongly punctured than the thorax, the punc- 

 tures arranged in closely approached double rows and rather 

 larger at the sides; below and the legs fulvous, the breast 

 more or less black. 



Larger than iV. dilecta Dalm., the thorax more finely 

 punctured and the anterior perpendicular grooves much dee- 

 per and longer, the elytra more finely punctured and the 

 interstices impunctate.
