the apex of the fifth ventral, the apex broadly and feebly sinuato-trun- 

 cate; sixth segment with a large triangular emargination at tip, gener- 

 ally not quite a third as wide as the apex and nearly as deep as wide, 

 the surface narrowly elevated along the median line toward the notch, 

 the ridge clothed with short stiff black spicules, some of the latter also 

 present at the apices of the segment at each side of the notch; female 

 with the sixth ventral not lobed, broadly rounded at tip and unim- 

 pressed. Length 8.0-9.0 mm.; width 1.1-1.3 mm. California (Sta. 

 Clara to Humboldt). [= lecontei Buviv.^ puncticeps Lee. 



Head less densely punctate, the interspaces always shining, the surface not 

 dull in lustre 3 



3— Head densely dull beneath, the micro-reticulation very strong. Body 

 smaller, rather stout, parallel, colored as in puncticeps; head well 

 developed, not very greatly though distinctly narrower than the elytra, 

 somewhat swollen toward base, the sides straight for some distance 

 behind the moderately small and rather prominent eyes, the angles very 

 broadly rounded, the base broadly rounded and feebly subtruncate, the 

 punctures coarse and rather close-set; antennae very stout, not as long 

 as the head and prothorax, the medial joints about a fourth longer than 

 wide; prothorax rather small, elongate-oval, much narrower than the 

 head, rattier coarsely and closely punctate, the smooth median line wide 

 and distinct; elytra parallel, slightly elongate, two-fifths wider and a 

 third longer than the prothorax, coarsely closely and irregularly punc- 

 tate; abdomen parallel, distinctly narrower than the elytra, finely, rather 

 densely punctulate and somewhat dull. Male with a small and very faint 

 oval impression at the apex of the fifth ventral, the sixth with a broadly 

 parabolic, shallow, gradually formed apical sinus, about a third as wide 

 as the segment, and sis times as wide as deep, the surface adjoining 

 extremely feebly impressed, the impression having a small patch of black 

 spicules anteriorly; female unknown. Length 7.2 mm.; width 1.15 

 mm. California, (Sta. Ana Caiion), — Mr. Wickham relictan. sp. 



Head shining beneath, the micro-reticulation feeble 4 



4 Elytral punctures confused in arrangement, except toward base, where 



they become unevenly serial. Body moderately stout, piceous-black, 

 the elytra dark rufous, the abdomen deep black; legs ferruginous, the 

 antennae dusky; head but little longer than wide, the sides parallel 

 and straight for a short distance behind the eyes, the angles very 

 broadly rounded thence to the neck, the punctures coarse, deep, sep- 

 arated by more than their own diameters, the vertex impunctate in the 

 middle; antennae stout, the medial joints much longer than the sub- 

 apical: prothorax elongate- oval, much narrower than the head, coarsely, 

 rather sparsely punctate; elytra distinctly elongate, parallel, coarsely 

 and rather closely punctate, about two-fifths wider and a fourth longer 

 than the prothorax; abdomen finely, closely punctulate, narrower than 

 the elytra. Male with a small unimpressed glabrous area at the middle 

 at apex of the fifth ventral, the sixth with a triangular impression, the 

 apex broadly, parabolically sinuate; female with the sixth ventral 

 obtusely rounded at tip, not lobed or impressed. Length 6.3-8.5 mm.; 

 width 10-1.35 mm. California (San Diego to Humboldt) and Nevada
