frontali armato ; prothorace quam longiori fere sesquilatiori, 
profunde (interrupte vel continenter) canaliculato, sparsius 
subtilius (in canalicule fundo sat crasse squamose) punctu- 
lato, lateribus modice arcuatis postice vix sinuatis ; scutello 
vix distincte punctulato ; elytris tricostatis (sutura costata 
haud inclusa), costa externa fere obsoleta, interstitiis sat 
crebre subseriatim punctulatis, parte apicali crebre confuse 
punctulata. 
Maris prothoracis canalicula antice leviter dilatata; pygidio 
antice crebre strigoso, postice crebrius sat fortiter punctu- 
lato. 
Femine pygidio toto crebre equaliter strigoso. Long., 65 —9

This species is very like that which I take to be S. Adelaide, 
Hope, differing from it by the external of the three elytral cost 
being almost non-existent and by the sculpture of the pygidium. 
In the male this segment is throughout more roughly sculptured, 
the basal strigose portion much narrower and the punctures of 
the apical portion coarser and closer. In the female the entire 
segment is closely and evenly strigose, while in 8. Adelaide the 
apical portion is impressed more or less sparsely with isolated 
punctures on a nitid surface.

Differs from Adelaide, meridianus, and longicollis by the more 
strongly rounded sides of its prothorax which are strongly, but
