only very moderate in size and notably dense throughout, the smooth 

 line narrow though evident in about basal half; scutellum rather trans- 

 verse, only feebly and very obtusely angulate behind; elytra nearly one- 

 half longer than wide, elongate-ovoidal in outline, only barely wider 

 than the prothorax and a little more than twice as long, the humeral 

 callus feeble, the apex evenly rounded and not very obtuse; grooves 

 deep but not coarse; intervals about three times as wide as the grooves, 

 and with single series of not very fine but feeble, well separated punctures, 

 closer laterally; setae not evident, the cluster at the base of the third 

 interval apparently altogether wanting; abdomen rather finely, some- 

 what loosely punctate, a little more coarsely and closely toward the sides. 

 Length (9) 3.25 mm.; width 1.2 mm. Colorado (probably from near 

 Denver) . 



Not closely allied to any other, being distinguishable by the 

 not coarse though very dense thoracic punctures and absence of 

 squamules on the elytra. The upper line of the beak is evenly 

 arcuate from tip to sulcus, as usual in the genus. 



Pseudobaris satyrica n. sp. — Elongate-oval, convex, rather shining and 

 deep black throughout; beak in the male not very slender, evenly arcu- 

 ate, closely and deeply though not coarsely punctate or rugulose through- 

 out and a little longer than the prothorax, which is a fourth wider than 

 long, the sides feebly converging and but slightly arcuate to fully apical 

 third, there gradually and moderately rounding to the tubulate apex, 

 which is fully half as wide as the base, the basal lobe rather abruptly 

 formed, well developed and evenly rounded; punctures rather coarse, 

 dense laterally, gradually very narrowly separated medially, the median 

 smooth line evident but not entire; scutellum transversely suboval; 

 elytra a little shorter and relatively somewhat broader than in the pre- 

 ceding, more feebly narrowing and more obtusely oval at apex, slightly 

 wider than the prothorax and barely twice as long, the humeral callus 

 rather small and feeble; grooves slightly coarser, deep; intervals twice 

 as wide as the grooves to much less, each with a single series of rather 

 small but distinct and well separated punctures; setae small but silvery, 

 everywhere distinct, and there are also a very few widely scattered scale- 

 like hairs; cluster at the base of the third interval well developed, denser 

 and distinct; pygidium convex, slightly shining, with small but deep and 

 very close-set punctures; abdomen rather coarsely but shallowly punc- 

 tate, having a deep elongate basal impression in the male. Length 

 (d^) 3-15 mm.; width 1.22 mm. Colorado (Greeley), — Wickham. 



Differs from nigrina in its stouter form, coarser pronotal punc- 

 tures, longer, thicker and more punctate beak in the male and in 

 the much deeper and longer basal abdominal impression in that 

 sex, there being but little more than a flattening in nigrina; it 

 differs very much from oscitans in the coarser and rather less dense 

 thoracic punctures and in the squamuHform hairs of the elytra.
