new Species o/'IIi.stcriila\ 361 



large and sliallow, with very tine points intermixed, the 

 lateral carinio continue behind the liead as an indistinct 

 marginal stria, vague and faintly crenulate, there is a shallow 

 antcscutellar depression; the elytra, humeral and sub- 

 humeral striaj complete and carinilbrm, six dorsal complete, 

 the sutural joining the fifth at the base, along the suturo is a 

 row of punctures set very regularly, which at first sight look 

 like an inner sutural stria, the first, second, and third striaj 

 are more or less carinifbrm, especially at their bases, the 

 interstices have a lineal punctuation ; the propygidium and 

 pygidiuni are punctured somewhat similarly to the thorax, 

 but are without the intermediate fine points ; the prosternum 

 irregularly punctate, striic carinifbrm between the coxai and 

 anteriorly greatly widen out, and continue to join in front as a 

 rim to the lobe ; the mesosternum, truncate anteriorly, trans- 

 verse and narrow, strongly margined at the sides, anterior 

 marginal stria scarcely visible, sparsely punctate, transverse 

 stria almost straight and crenulate ; the rnetasternum and 

 first abdominal segment also sparsely punctate ; the legs and 

 antennae concolorous, club of the latter paler. 



This species is more oval (not broadly oval) than S. cali- 

 /orm'ciis, Horn. The long basal joint of the antenna, the 

 broad prosternum, the narrow transverse mesosternum, form 

 of the legs, and general dorsal sculpture leave no doubt in 

 my mind that the species is congeneric with S. parra, Mars., 

 from Australia.

L. 2| mill. 



Nearly orbicular in outline, convex, black, and shining; 

 the legs and antennfe pitchy brown ; the head with an ex- 

 tremely fine punctuation, stria well marked and semicircular 

 in outline (a character possessed by other species of this 

 section) ; the thorax, marginal stria entire, raised at t he 

 angles, feebly crenulate behind the nec'.c ; surface very finely 

 punctulate on the disk, with larger points broadly scattered
