tures, the frontal tubercles small and obsolete, palpi slender, 

 antennae extending slightly below the base of the antennae, 

 testaceous, the apical joints obscure fuscous, the third joint 

 slightly longer than the second, the fourth and following joints 

 rather shorter, the apical two joints more elongate again; thorax 

 nearly twice as broad as long, the sides strongly and evenly 

 rounded, the anterior margin straight, the basal one with a 

 rather long perpendicular groove at each side, the surface con- 

 vex, distinctly and very closely punctured ; elytra scarcely more 

 strongly punctured than the thorax, the punctures arranged in 

 close but rather irregular rows which near the suture approach 

 in pairs, the punctures themselves getting rather smaller at that 

 part ; legs rather robust, the prosternum proportionately broad, 

 narrowed between the coxae. 



Hab. Da Dime al Bass Narok. 



This is another small Nisotra closely allied to N. testacea, Chap. 

 and iV. Ckapuisi, Jac; it differs from the first in the different 

 colour of the antennae , that of the underside and the femora 

 and in the punctuation of the elytra which only shows \ two 

 double rows of punctures near the suture, the general size is 

 also large ; from N. Chapuisi the present species may be known 

 by the long perpendicular thoracic groove which is only indi- 

 cated in the allied species and in the more strongly punctured 

 thorax and elytra. 



11. Phyllotreta tenuimarginata, sp. n. — Black, the basal joints 

 of the antennae and the tibiae and tarsi flavous, the head and 

 thorax fuscous, closely punctured, elytra very finely punctured, 

 testaceous or flavous, very narrowly margined with piceous, 

 posterior femora piceous. 



Length 2 millim. 



Head fuscous, extremely finely punctured and granulate, the 

 frontal elevations absent, the clypeus with a distinctly raised 

 central ridge, its anterior edge straight, palpi pale piceous, an- 

 tennae not quite extending to the middle of the elytra, shorter 

 in the female, flavous, the terminal joints fuscous, the second 

 and third joint equal, the fourth slightly longer, terminal joints
