230 f March, 



gree), I do not see how these points can be of help. The male is rather 

 narrower than the female, and its thorax appears to be a little more 

 elongate. This insect varies somewhat in depth of colour, but is usually 

 greyish-yellow. 



Common in clover and lucerne fields.* 



S. STJTUBALis, Steph. The smaller size, more depressed eyes, and 

 longitudinal bauds of colour, distinguish this species from flavescens^ 

 with which it agrees iu many points of structure. Its depressed eyes, 

 metallic hue, and shorter, more robust, and less parallel elytra separate 

 it from lineatus ; and the very prominent eyes of tibialis (the only other 

 species at all like it,) at once distinguish that insect from suturalis ; the 

 latter is always metallic, varying from greenish to coppery or golden- 

 purple, the suture being considerably lighter," and the tibiae and an- 

 tennae testaceous. 



According to Allard it feeds on furze. It occurs near London in 

 damp meadows, and I have taken it in wet places in Derbyshire. 



S. SULCIFEONS, Thunb. Somewhat similar in build to suturalis, 

 but smaller, and readily distinguished by the strong depression between 

 the eyes, and the scantier scales ; indeed, the small size and frontal 

 excavation will serve to separate it from all the other species. It is 

 slightly metallic, sparingly clothed with scales (having always a some- 

 what abraded look), and with short elytra. The legs are sometimes 

 entirely ferruginous. 



Abundant in lucerne, &c., especially on the south coast. 



S. TIBIALIS, Herbst. This species varies exceedingly in size and 

 colour, and also somewhat in shape, the males being narrower and more 

 cylindrical. The commonest form is about the size of suturalis, oblong, 

 very convex ; clothed with very short, inconspicuous bristles (only 

 visible under a strong lens), and brownish-grey, somewhat metallic, 

 scales, variegated by three not very well defined longitudinal bands of 

 silvery, greenish, or slightly coppery scales on the thorax and elytra. 

 The tibiae are usually testaceous ; but the legs are sometimes uniformly 



* An allied species, S. longicollU, Schon , occurs in temperate Europe, as far north as Paris. It 

 resembles a sviall specimen of flaveicens, but differs in having the furrow on its forehead deeper, the 

 eyes a little more prominent, and the thorax evidently more elongate, and more distinctly punctured. 

 It has, moreover, no white spots on the thorax or head, and the punctuation of the strife of the elytra is 

 stronger. 



Another allied species, 5. longulut, Schbn., Is found in North Germany, &c. It resembles iS. ton- 

 gicollis, but Its thorax is ratlier shorter, narrower at the base than at the apex, and unequal, with a 

 slight double impression on each side of the median line. The elytra are longer, and very decidedly 

 narrower, with the base truncate; they are a little contracted at the shoulders, which are rounded, and 

 are thence slightly enlarged, again contracting in their lower third.
