126 CASEY 



vergent anteriorly, slightly wider near the middle than at base, the 

 apex not more than three-fifths as wide as the base, the angles 

 obtuse and broadly rounded, more deflexed than usual ; surface 

 very finely, rather sparsely punctate, more strongly but still not 

 coarsely and almost equally sparsely so toward the sides, the bead 

 rather fine, slightly curving at base ; scutellum and elytra nearly 

 as in nemoralis^ the latter scarcely one-half longer than wide, 

 gradually arcuately narrowed behind the middle, the apex ogival, 

 though narrowly obtuse ; surface and punctures uneven, nearly as 

 in nemoralis ; under surface nearly similar. Length 7.25 mm. ; 

 width 3.3 mm. " Cal." parva n. sp. 



16 — Body oblong, rather stout, very small in size, similar to the pre- 



ceding in coloration but more shining, the anterior parts not at all 

 alutaceous ; head moderately large, strongly, subevenly but not 

 very closely punctate, the sinus nearly as in parva^ the anterior 

 canthus much more obtusely rounded and scarcely at all less prom- 

 inent than the posterior; prothorax fully three-fifths wider than 

 long, nearly as in nemoralis^ the apex more than two-thirds as 

 wide as the base ; surface finely but distinctly, sparsely punc- 

 tate, more strongly and less sparsely toward the sides, the bead 

 moderate, curving very slightly at base, the basal angles very 

 blunt ; scutellum rather small ; elytra short, two-fifths longer than 

 wide, otherwise nearly as in parva though smoother, rugulose api- 

 cally, the punctures not coarse but strong, well separated and 

 rather unequally distributed ; prosternum finely but strongly, 

 sparsely punctate, the process rather narrow, evenly and strongly 

 convex longitudinally, margined only at base ; hind femora and 

 abdomen very minutely, sparsely and inconspicuously punctulate.

17 — Body deep black in color throughout, inhabiting the mainland 



exclusively 18 



Body piceous to pale testaceous in color; habitat insular 26 



18 — Elytral punctures only moderately coarse, relatively fine for the 



present group 19 



Elytral punctui-es very coarse and generally deep 23 



19 — Small species, never as much as lo.o mm. in length 20 



Larger species never less than 10. o mm. in length 21 



20 — Elytra unequally punctate, very remotely so, with the surface 



nearly smooth, becoming more coarsely and closely with the sur- 

 face very rugose apically. Body oblong-oval, moderately convex, 

 deep black, the tarsi and antennal base and apex piceo-rufous, very 

 highly polished throughout ; head strongly but sparsely punctate, 

 the sinus only moderate in width, deep and parabolic, the anterior 

 canthus obliquely rounded, as prominent as the posterior ; antennae 

 moderately thick ; prothorax fully two-thirds wider than long, the 

 sides broadly rounded and converging before the middle, beconi-
