1420 COLEOPTEEA 



small, but longer than ic is broad ; 4-6 subequal, each longer than 

 broad ; 7-10 become shorter, and rather broader. Thorax cordate, 

 with a large impression behind the middle, two small foveas near 

 the base, and a large impression at each side, behind the middle, 

 withiti this lateral impression there is a small fovea, near the angle. 

 Elytra oblong, their posterior angles rounded ; the sutural strite are 

 well marked, the intrahumeral impressions appear more or less 

 interrupted. Hiiid-hody not larger than the elytra, slightly infus- 

 cate, its first visible segment finely sculptured, with minute scales 

 near the base, the extremity with short hairs as well as the ordinary 

 pubescence ; second and third segments equal. Legs simple. 



Underside of head with a transverse depression behind the men- 

 tum. Anterior trochanters acutely prominent. Fifth ventral seg- 

 ment with two minute tubercles. 



This comes near S. major. After a careful comparison with its 

 nearest allies, Nos. 1157, 1573, 1576, and 1875, I find it is 

 distinct. 



3 . Length, 1| lines ; breadth, % line. 



Hunua Eange, Clevedon. One example, from Mr. Munro. 



Obs. — I possess about a dozen specimens which cannot be 

 referred to described species ; but, as they appear to be females, and 

 as they do not exhibit well-marked differentiating characters, I leave 

 them without specific names for the present. The genus will ulti- 

 mately comprise a great many species, and, as they are already very 

 difficult to distinguish from one another in many cases, I hope next 

 winter to draw up a table, or key, that will facilitate their discrimi- 

 nation. On attempting this work during the present season I found 

 that more examples of the male sex were needed : some of these I 

 expect to find during the year. 



2468. S. robusta, i^-s- Bobust, shining, red ; elytra, legs, and 

 palpi fulvous. 



Head large, nearly the same width as the thorax, just a little 

 narrowed behind the eyes ; sparingly clothed above with slender, 

 decumbent, yellow hairs, those on the gense more conspicuous ; the 

 distinct frontal channel is expanded behind the tubercles but 

 becomes linear on the vertex, on the back part there are two 

 broad impressions ; the tubercles are flat, and approximate in 

 front. Thorax about as long as it is broad, widest before the 

 middle, very much contracted posteriorly, the base only half the 

 breadth of the middle ; there is a fovea on the middle, near the base, 

 a smaller one near each hind angle, and a longitudinal lateral im- 

 pression which causes the side, near the middle, to aj)pear swollen ; 

 its pubescence is like that of the head, but there are coarser hairs on 

 the sides. Elytra broader than long, wider than the thorax, con- 

 siderably narrowed towards the base, apices subtruncate ; they are 

 obsoletely punctured, the sutural striae are broad and deep, the intra- 

 humeral impressions are rather short, deep, and entire, there are no 

 distinct plicae, and they appear as if transversely depressed before 

 the middle ; the pubescence is rather coarser and longer than that
