times as long as wide; prothorax a third (d" ) to two-fifths (9 ) wider 

 than long, strongly and evenly rounded at the sides, the latter ob- 

 lique and gradually more sinuate in about basal half, the angles 

 right and sharp; stria fine between the feeble transverse impressions; 

 margins well reflexed ; foveae large, rugulose and shallow, briefly 

 sublineate at the bottom, the carina long and strong; elytra some- 

 what inflated posteriorly, one-half longer than wide, one-half wider 

 than the prothorax, the striae fine, moderately impressed, gradually 

 feeble laterally, the seventh easily glimpsible at certain angles of 

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

 (Stikine River Canon), Wickham. Six examples .bucolicum n. sp. 



Body strongly ventricose, shining, black, with feeble greenish lustre 

 anteriorly, the elytra bright and pale testaceous-brown; under sur- 

 face black, the epipleura brown; head three-fourths to nearly four- 

 fifths (cf) as wide as the prothorax, with broad but deep sulci; 

 antennae slender, fuscous, the basal joint rufous, nearly as long as 

 the elytra, the medial joints somewhat more than three times as 

 long as wide; prothorax a fourth to third wider than long, the base 

 and apex subequal, the sides widely reflexed, broadly, evenly arcu- 

 ate, becoming rapidly sinuate and parallel near the base, the angles 

 right and sharp, the apical angles obtuse and rather blunt; surface 

 with the stria stibentire, the foveae large, shallow and rugose, deeply 

 and briefly sublinear medially at base, the carina long and strong; 

 elytra one-half longer than wide to somewhat less, the posterior 

 inflation barely at all evident, the sides broadly arcuate, broadly 

 parabolic in about apical third, two-thirds to three-fourths wider 

 than the prothorax; striae fine, barely at all impressed though dis- 

 tinct and subequal but feebler laterally, entire as usual in this group; 

 foveae moderate, near three-sevenths and three-fourths. Length 

 (cf 9 ) 4.0-4.8 mm.; width 1.65-1.85 mm. Colorado. Levette col- 

 lection. Fourteen examples, displaying but little variability. 



gratiosum n. sp. 



39 Body elongate-suboval, moderately convex, the type pale yellowish- 

 testaceous throughout, with the legs straw-yellow, shining, the head 

 faintly alutaceous, the sulci rather shallow; antennae very slender 

 and elongate, about as long as the elytra, slightly fuscous, paler 

 basally, the first joint palest; medial joints fully three times as long 

 as wide; prothorax a third wider than the head, two-fifths wider 

 than long,' broadly reflexed at the sides, which are strongly, sub- 

 evenly rounded, becoming oblique but only just visibly sinuate in 

 about basal half, the angles right and sharp; surface with the fine 

 stria extending from the apical margin to the pronounced trans- 

 verse subbasal impression, the base somewhat depressed and punc- 

 tulate; near basal fifth there is a short oblique obtuse elevation, ex- 

 tending to the marginal gutter; foveae large, moderately deep, 

 smooth, subbistriate; the usual carina is wanting and replaced by 

 the oblique elevation; elytra oval, with evenly arcuate sides, rather 

 more than one-half longer than wide and one-half wider than the 

 prothorax; striae very fine, entire though extremely feeble, having
