sevenths wider than the prothorax, slightly wider behind the middle 

 than at base, evenly rounded in apical two-fifths; striae entire, deeply 

 impressed, becoming very shallow, fine and feeble laterally, all mi- 

 nutely, remotely and irregularly punctulate; foveae irregular, at three- 

 sevenths and before apical third, mutually much less separated than 

 the second from the apex. Length (c?) 3.4 mm.; width 1.4 mm. 

 Queen Charlotte Islands (Massett), Keen viator n. sp. 



Black, shining, the upper surface with strong bronze lustre throughout, 

 the under surface and legs black; head rather well developed, four- 

 fifths as wide as the prothorax, the sulci rather broad, alutaceous; 

 antennae black, very slender, the fourth joint about three times as 

 long as wide; prothorax short, fully three-fifths wider than long, the 

 sides anteriorly evenly rounded, becoming oblique and broadly, very 

 feebly sinuate in basal half, the angles obtuse but sharp; surface 

 much less convex than in viator, the transverse impressions very 

 faint, the stria not entire, the sides rather widely reflexed; foveae 

 large, rugulose, very shallow, with a more impressed short line at 

 base beyond lateral fourth, the carina rather long and strong; elytra 

 oblong, subparallel, three-sevenths longer than wide, two-fifths wider 

 than the prothorax, subcircularly rounded in fully apical third; 

 striae fine, moderately impressed suturally, feeble externally, the 

 seventh scarcely observable except under a certain angle of illu- 

 mination; foveae irregular, at three-sevenths and three-fourths. 

 Length (<f) 34mm.; width 1.5 mm. British Columbia (Metlakatla), 

 -Keen illex n. sp. 



32 Elytra subinflated posteriorly, wider behind the middle than at 

 base, the foveae lying within shallow impressions, which however do 

 not differ in character from the general surface 33 



Elytra parallel, the foveae not lying within areas of impression; shining, 

 the head faintly alutaceous 34 



33 Body and legs deep shining black, without metallic lustre of any 

 kind, the head alutaceous, the trochanters paler; head well devel- 

 oped, three-fourths as wide as the prothorax, slightly narrower than 

 an elytron, the sulci broad, rather deeply impressed; eyes large and 

 prominent; antennae slender, black, three-fourths as long as the ely- 

 tra, the medial joints not quite three times as long as wide; prothorax 

 short, one-half (cf) to three-fifths (9) wider than long, the sides 

 strongly, evenly arcuate, converging and broadly, strongly sinuate 

 basally, the angles right and very sharp, the apical angles obtuse 

 but only slightly blunt; side margins broadly reflexed; stria only 

 attaining the pronounced anterior transverse impression; foveae 

 deeply, linearly impressed, rugose, the carina long and strong; ely- 

 tra about one-half longer than wide, one-half wider than the pro- 

 thorax, parabolic in apical two-fifths; striae subequal, strong, finer 

 but distinct laterally, entire, the foveae just before the middle and 

 near apical third; second and fifth striae deeper at apex. Length 

 (cf 1 9 ) 4.2-4.8 mm.; width 1.7-2.2 mm. British Columbia (Inver- 

 ness and Metlakatla), Keen. Fourteen examples.. haruspex n. sp.

 surface greenish-black; legs black, the femora gradually toward base,
