four-sevenths. Length (cf) 3.25 mm.; width 1.25 mm. California 

 (Lake Tahoe) tersum n. sp. 



13 Elytral striae distinct and distinctly punctured to the summit of 

 the declivity. Body moderately slender, convex and ventricose, 

 polished black, the elytra with feeble piceous tinge and with the 

 apex and a large external posterior spot pale, the two united along 

 the margin; under surface black, the epipleura piceo-rufous, the legs 

 rufous; head five-sixths as wide as the prothorax, of the usual struc- 

 ture; antennae three-fourths as long as the elytra, fuscous, gradually 

 rufous basally, the medial joints slightly more than twice as long as 

 wide; prothorax a fifth or sixth wider than long; base distinctly nar- 

 rower than the truncate apex and fully three-fourths the maximum 

 width; sides rounded anteriorly, well reflexed, converging and be- 

 coming sinuate posteriorly, subparallel for some distance from the 

 angles, which are sharp, slightly more than right; anterior impression 

 subobsolete, the posterior broad, punctulate, obsolete medially, the 

 stria fine, not quite entire; foveae rather large, deep, oblong, adjacent 

 to the carina, which is long and strong; elytra parallel, with arcuate 

 sides and rather rapidly rounded humeri, one-half longer than wide 

 and two-thirds wider than the prothorax; striae rather coarse, barely 

 visibly impressed, obsolete in apical fourth, the seventh in half; 

 punctures rather coarse, deep, moderately separated, distinct to 

 the ends of the striae; foveae near fourth and two-thirds. Length 

 (cf) 3.1 mm.; width 1.18 mm. New Mexico (road between Fort 

 Wingate and Jemez Springs), \Yoodgate invidiosum n. sp. 



Elytral striae barely at all traceable behind the middle 14 



14 Form moderately slender, convex, deep black, shining, the elytra 

 with subnubilous posterior pale maculation as in the preceding; 

 legs piceo-rufous; head not distinctly narrower than the prothorax, 

 with rather large and prominent eyes and the usual deep sulci, the 

 inter-sulcal surface obtuse at tip, however, and not so acute as in 

 some other species; antennae three-fourths as long as the elytra, 

 more slender, black, the basal joint rufous, the medial joints two 

 and one-half times as long as wide; prothorax a fifth or sixth wider 

 than long; base distinctly narrower than the truncate apex and three- 

 fourths the maximum width; sides rather narrowly but strongly 

 reflexed, evenly rounded from apex to the parallel basal part, which 

 is a fifth the total length; anterior impression only medial, broadly 

 concave, the posterior reduced to a small impression at each side of 

 the middle; foveae deep, narrow, sublinear, not adjacent to the car- 

 ina, which is distinct; elytra three-fifths longer than wide, fully 

 two-thirds wider than the prothorax, parallel, with slightly arcuate 

 sides and somewhat gradually rounded humeri; striae fine, scarcely 

 impressed, consisting simply of series of fine and widely separated 

 punctures, sometimes a little coarser basally behind the humeri; 

 foveae near two and four sevenths. Length (cf) 3.25 mm.; width 

 1.25 mm. Illinois (Highland Park) and Michigan (Marquette).
