NEW SPECIES OF PHYTOPHAGA o3t) 



There are but few genera of the Galerucinae known which 

 have simple claws, and none in which this is the case in con- 

 nection with closed anterior coxal cavities. The genus here pro- 

 posed is an exception and will on that account be comparatively 

 easy of recognition. The species on which it is founded is of 

 delicate Lupe r us like appearance and makes the impression of 

 being immature on account of it very pale coloration but all 

 the specimens before me are alike. 



18. Rudolphia pallida, sp. n. — Yellowish-white, the head pale 

 fulvous, terminal joints of the antennae obscure fuscous, thorax 

 not perceptibly, elytra extremely finely punctured. 



Length 4 millim. 



Head with a few extremely fine punctures, very pale fulvous, 

 the frontal tubercles in shape of narrow transverse ridges, the 

 clypeus with an acutely raised central ridge, apex of mandibles 

 black, antennae extending below the middle of the elytra, pale 

 flavous, the apex of the last joint fuscous, the third joint one 

 half longer than the second, the fourth and following joints 

 longer and nearly equal ; thorax twice as broad as long , the 

 sides straight, the posterior angles oblique, the anterior ones not 

 produced, the surface not perceptibly punctured, elytra very 

 minutely punctured ; below coloured like the upper surface, the 

 abdomen pale fuscous. 



Hab. Da Dime al Lago Bass Narok. July -August. Four spe- 

 cimens. 



As already remarked above, all the specimens make the im- 

 pression by their almost entirely white coloration of being im- 

 mature, which is further strengthened by the irregular impres- 

 sions of the thorax and elytra in every case, as if the insects 

 were in a semihardened condition when captured, but as to this 

 I cannot of course speak with certainty. 



The genus is named after the Lake Rudolph which is syno- 

 nvmic with Bass Narok where it was discovered.
