Mas. The apcx of the posterior tibiae produced inlo a short 

 slvlit'orm process. 



var. Antennae entirel}- black. 



Length 5 — 6 mill. 



Much smaller and narrower than the prcceding species, 

 bat of nearly similar coloration, the head entirely inipunctate, 

 metalUc bkie or purple, frontal elevations strongly raised, tri- 

 angulär, divided by a deep longitudinal groove, the apex connected 

 with the carina, the latter acute and long, labrum black, palpi 

 flavous, antennae very slender, nearly extending to the apex of 

 the elytra, black, or with the eighth and ninth Joint flavous, 

 basal Joint long and slender at the base, second very short, 

 third and following oncs very elongate, nearly equal; thorax 

 transverse, the sides nearly straight, the angles tuberculiform, 

 the surface entirely impunctate, deeply transversely sulcate, 

 scutellum rather broad, impunctate; elytra without basal depression, 

 minutely punctured and very finely granulate, their epipleurae 

 broad and continued; below bluish black, very shining, legs 

 slender, flavous, the tibiae and tarsi fuscous, clothed with yellow 

 pubescence, the metatarsus of the posterior legs very elongate, 

 longer than the following joints together. 



The much smaller size of this insect and the want of an 

 elvtral basal elevation separates this species principally from the 

 preceding ones; the last abdominal segment of the male has the 

 median lobe slightly prolonged beyond the lateral divisions 

 and is flattened, in the female the same i)art is simple and 

 nearly truncate. 



Platyxantha longicornis sp. n. 



Flavous below, above fulvous, the antennae very long, 

 black (the basal Joint excepted) thorax subquadrate, transversely 

 sulcate, elytra, exti'emely minutely punctured. 



Length 5 mill.
