feimall elongate fovea. Ilostruin loBger than head, slightly longer 

 than broad, its sides quite straight and parallel to apex, the 

 pterygia not dilated ; npper surface almost plane, rugosely punc- 

 tured, with a narrow cential carina and the margins sharply 

 carinate. Antenna' very slender, ferruginous, with the club and 

 apices of all the joints infuscate ; scape very slender, cylindrical 

 and abruptly clavate. Frothorax transverse (more so in $ ), 

 broadest behind middle ; sides strongly rounded in S , only 

 slightly so in $ , apex narrower than base ; upper sui'face convex, 

 bare, shining and without punctures or granules, sometimes with 

 faint transverse aciculation or with traces of a central stria,, 

 lateral margin aciculate and with a stripe of pale scales. Elytra 

 broadly ovate in $ , much narrower and more elongate in c? , 

 truncate at base ; shoulders extremely oblique ; upper surface 

 convex, with closely punctured stride, the intervals broad, convex, 

 smooth and very finely aciculate ; entirely devoid of setse. Legs^ 

 piceous black, with sparse pale scaling and setse ; simple in 5 ^ 

 except for a shallow excavation near apex of anterior tibiae : 

 in S the anterior tibias are thickened latei'ally and with a stout 

 perpendicular tooth about middle of the inner margin, while on 

 the underside there is a laige curved tooth, the outer apical half 

 of the tibia being deeply excavated ; the intermediate tibi?e have 

 a long, slender, curved tooth before middle, while the posterioi-^ 

 tibife are strongly but simply curved, with their inner surface 

 flattened.

Types, (S in the British Museum, $ in the Oxford Museum. 



An isolated species, somewhat resembling S. aonplicoUis Gerst. 

 in general facies, but the structure of the legs is veiy difierent 

 and the elytra are not constricted at the base as in that species;, 

 further, denti23es dilfers from this and all other described Systates 

 known to me in the comjolete absence of granules on the pro- 

 thorax. 



It is a common insect about Salisbuiy thioughout the summer,, 

 feeding on various grasses.

Head broadly but shallowly depressed on forehead ; eyes short 

 ovate, scarcely prominent. Rostrum scarcely longer than head, 

 almost as broad as long, elevated and compressed between the 

 antennfe and with a distinct central furrow which is broader and 

 shallower towards base. Antennce rather slender and elongate, 

 squamose, and with scattered short white setse ; funicular- joints 

 of normal length. Pro^Aorrta? transverse, broadest at base and 

 regularly narrowed to apex, the sides being slightly rounded ;
