398 Major T. Broun on new Genera and 



fine but distinct throughout ; the surface distinctly and 

 irregularly but not coarsely or closely punctured. Scutellum 

 large, minutely punctured, tlie dark spot almost smooth. 

 Elytra elongate, oblong, somewhat expanded behind the 

 middle, the apices, conjointly, broadly rounded, and finely 

 margined nearly to the sutnre ; each has thiee more or less 

 definite costiP, which, however, do not reach the apex, the 

 suture is a little rufescent and elevated behind the middle 

 and finely punctate ; their whole surface distinctly and 

 irregularly punctured and uneven, the marginal punctuation 

 is serial. Legs pnle brown, sparsely setose, front tibiie tri- 

 dentate, tarsi long and slender. 



Underside nearly nude, shining fuso-testaceous, the basal 

 four ventral segments about equal, more or less longitudinally 

 striate ; metasternum irregularly punctate, medially chan- 

 nelled ; prosternal process subtriangular, short, with a red 

 median carina. 



Antenna 8-articulate, basal joint cylindrical at the base, 

 knobbed at apex ; second short and thick ; fourth quite as 

 long as the elongate third, its basal angle di-tinctly pro- 

 jecting backwards but not elongated as in SericospUns advena ; 

 club with four equally elongate, strongly pul)escent leaflets. 



Very similar to E. coste'la, with a shorter thorax, stouter 

 legs, and differing in numerous details. The elyti'a more 

 irregularly marked and decidedly more aeneous and quite 

 violaceous on some spots. Easily recognisable by the more 

 slender and elongate fourth joint of the antennae. With the 

 exception of the different structure of that j lint, SericosjA/us 

 can hardly be separated from the older Eusoma.

Westport. Two imperfect males from Mr. G. Y. Hudson ; 

 found by Commander J. J. Walker. 



Lewisiella, gen. nov. 



Body subovate, moderately convex, almost nude, bearing 

 onlv some minute inconspicuous setae. Head broad. Labrum 

 prominent, nearly horizontal, deeply emarginate. Clypeus 

 with reflexed margins, obtusely curvate, its basal suture 

 nearly straight. Antenna 8-articulate, basal joint elongate, 

 rather slender, clavate towards extremity, only about half of 

 its length exposed above, oblique and concave at apex ; 

 second slightly longer and much stouter than third ; fourth 

 short and stout, oblique at the extremity (sometimes thicker 

 than the third and of the same length) ; fifth short, prolonged 

 inwardly so as to be half or two-thirds the length of the
