angles obtuse but distinctly defined; edge moderately reflexed, 

 rapidly strongly so at the basal angles; base as wide as the very 

 moderately sinuate apex, obliquely rounded at the sides; surface 

 polished, with a few rugulse near the impressed median stria, both 

 transverse impressions feeble but obvious; foveae rather deeply 

 concave, nearly smooth; elytra scarcely one-half longer than wide, 

 almost twice as wide as the prothorax, somewhat wider behind the 

 middle than at base, gradually but somewhat obtusely rounded 

 behind, with feeble sinus; strise fine, distinctly impressed, the usual 

 close punctulation extremely minute; intervals evidently convex, 

 strongly shining and smooth, the three dorsal punctures unusually 

 distinct but in the usual positions; anterior male tarsi long and 

 feebly though obviously dilated, the second joint one-half longer 

 than wide. Length (d^) 6.2 mm.; width 2.4 mm. Oregon (New- 

 port), — Wickham metuens n. sp. 



Form still narrower than in metuens and more depressed, highly polished 

 throughout, deep black, the entire upper surface with feeble aeneo- 

 greenish metallic lustre; legs black, slender; head three-fourths as 

 wide as the prothorax, with the eyes prominent as in metuens, the 

 antennae nearly similar, black throughout; prothorax shorter and 

 broader, fully two-fifths wider than long, the outline and angles 

 nearly similar, the foveae similarly deep but rather longer and still 

 more nearly smooth, feebly punctulate; elytra slightly less than one- 

 half longer than wide, one-half wider than the prothorax, more 

 gradually narrowed behind, the sinus more oblique, feeble; strise 

 finer, feebly micro-punctulate, scarcely at all impressed; intervals 

 nearly flat, the three dorsal punctures not quite so large as in 

 metuens but similarly arranged; anterior male tarsi very moder- 

 ately dilated though more so than in metuens and shorter, the second 

 joint only very little longer than wide. Length (cf) 6.5 mm.; 

 width 2.35 mm. Oregon (Dille}-). — Leng dilleyanus n. sp. 



There are doubtless many more species of this section to be 

 found in the numerous isolated ravines of the Sierras and in the 

 coast mountains of California and Oregon. Quadratus was de- 

 scribed from a dilapidated Oregon specimen, but the above identi- 

 fication is probably correct. Through an evident oversight rmcans 

 Men., was made a synonym of funehris by LeConte, although 

 published ten years earlier. 



Section Taphranchus. 

 In this section the body is small and moderately convex, rather 

 stout and with aeneo-metallic lustre, the third and fourth antennal 

 joints about equal, the short convex prothorax with large rugose 

 fovese, which are not anteriorly prolonged, obtuse though sharp 

 basal angles and very finely reflexed sides, not definitely more
