328 Memoirs on the Coleoptera 



The coloration in this species differs from that of the other alHes 

 of rubripes, and the beak is much shorter. It is really more closely 

 related to inculta than to rubripes. 



The two following are subopaque species allied to opacula but 

 manifestly different: 



Baris alternans n. sp. — Deep black, feebly shining, the elytra opaculate, 

 the legs bright red; beak in the male not very stout, feebly arcuate, 

 rather densely punctate, three-fourths as long as the prothorax and 

 black, the antennae black; prothorax with evenly arcuate upper profile, 

 a fourth wider than long, the sides feebly converging and slightly arcuate, 

 gradually rounding and more converging in about apical third ; punctures 

 deep, moderate in size and very close throughout, not larger but still 

 denser laterad, the smooth median line very fine though evident through 

 most of the length; basal lobe rather small, the scutellum small, quadrate, 

 impressed behind; elytra long, nearly one-half longer than wide, only 

 slightly wider than the prothorax and almost twice as long, the sides 

 very feebly converging and slightly arcuate, gradually circularly rounded 

 behind, the humeri moderately prominent; grooves deep but only mod- 

 erately coarse, more or less evidently crenulate; intervals three to almost 

 four times as wide as the grooves, with fine and moderately separated 

 punctures, confused on the broader, in single series on the narrower, the 

 third and fifth much wider than the others; setae minute but glistening; 

 abdomen slightly shining, with strong but not very coarse, rather dense 

 punctures throughout, the male with a shallow basal impression, grad- 

 ually evanescent near the tip of the second segment. Length (cf ) 4.2 

 mm.; width 1.75 mm. California (southern). 



The male type of this species differs from the female type of 

 opacula in the much denser abdominal punctures, unequal strial 

 intervals, only the third being wider in opacula, in the larger pro- 

 thorax, stouter form of body and more coarsely, densely and 

 rugosely punctate beak. 



Baris planifera n. sp. — Still larger and stouter than opacula; coloration 

 and lustre as in the preceding, except that the legs are blackish-piceous 

 and not clear red; beak in the female arcuate, cylindric, finely, closely 

 and evenly punctulate and three-fourths as long as the prothorax, the 

 latter with evenly arcuate upper profile, two-fifths wider than long, the 

 sides subevenly arcuate throughout, more parallel basally and slightly 

 more converging apically; punctures moderately coarse, very deep and 

 closely cribrate, very dense and sublineate at the sides, the median line 

 wholly obsolete, the basal lobe short, broadly rounded and feeble, the 

 scutellum small, subquadrate; elytra two-fifths longer than wide, very 

 slightly wider than the prothorax and almost twice as long, the sub- 

 parallel sides feebly arcuate, very gradually rounding behind; humeri 

 feebly prominent, closely punctulate internally; grooves moderately 

 coarse, deep, with shining and lineato-punctate bottom, but not at all
