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 1.1-1.83 mm. California (Sta.

8— 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, rather 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 withasmall 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 six 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

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 areaat 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 1.0-1.35 mm. California (San Diego to Humboldt) and Nevada
