BYRRHID/E 61 



lobed, the first joint about one-half longer than the second, the 

 claws well developed, rather slender, more strongly arcuate basally. 

 The species may be known by the following characters: 



Upper surface never deeply, though sometimes rather evidently, punc- 

 tate 2 



Upper surface deeply punctate 6 



2 Color bright metallic green 3 



Color pale brownish-testaceous throughout, without metallic reflection. . 5 

 3 Elytra much longer, oblong, almost three times as long as the pro- 

 thorax and with somewhat coarse, distinct and subentire impressed 

 lines. Rather elongate, subparallel, the elytra but little wider than 

 the prothorax, polished, black, with strong green lustre, the under 

 surface black, shining but non-metallic; the legs pale brown; head 

 almost evenly, feebly convex, with remote and feebly impressed 

 punctures; prothorax twice as wide as long, the sides rounded, be- 

 coming parallel in about basal half, converging anteriorly, the sur- 

 face strongly convex, even, with small and very sparsely scattered, 

 feebly impressed punctures, each bearing a moderately long fine 

 erect hair; scutellum glabrous; elytra a little less than one-half 

 longer than wide, oblong-oval, the sides parallel and very moderately 

 arcuate, rounding and converging much more rapidly in barely 

 apical third to the rather obtusely ogival tip, the surface with feebly 

 though distinctly and broadly impressed, minutely, sparsely punc- 

 tate lines, the subconvex intervals each with a sparse uneven series 

 of larger but feeble, more asperate punctures, bearing rather long 

 erect hairs; under surface sparsely, feebly and irregularly punctate. 

 Length 2.7-3.3 mm.; width 1.3-1.7 mm. British Columbia (Met- 



lakatla), J. H. Keen. Abundant striolatus n. sp. 



Elytra shorter, more oval, more inflated, never much more than twice 

 as long as the prothorax, less punctured and never with very obvious 



impressed lines 4 



4 Stout, the hind body only very moderately inflated, black, with 

 polished green lustre, generally more aeneo-viridate anteriorly, black- 

 ish beneath, the abdominal apex and legs pale brown; head with 

 very feeble remote punctures, obsoletely impressed along the median 

 line of the vertex; prothorax slightly less than twice as wide as long, 

 the sides broadly rounded, converging anteriorly, becoming a little 

 more rounded and subparallel only in about basal third, the surface 

 very convex, even, very finely and remotely, scarcely visibly punc- 

 tate, the short erect hairs generally denuded; elytra barely a third 

 longer than wide, a sixth or less wider than the prothorax, widest 

 well before the middle, the sides broadly, evenly rounded, gradually 

 converging but constantly more rapidly to the rather acutely ogival 

 apex, the surface with feeble traces of impressed lines, which are 

 much finer than in the preceding, the interstitial punctures very 

 small, sparse and scarcely distinct, each bearing a moderately long 

 erect hair; under surface nearly as in striolatus. Length 2.7-3.0 mm. ; 

 width 1.35-1.55 mm. British Columbia (Metlakatla), Keen.
