Barin.e 313 



twice their diameters medially, gradually coarse and denser thence to 

 the sides, the median smooth line short, feebly defined; scutellum small, 

 impressed medially at apex; elytra fully two-fifths longer than wide, 

 very little wider than the prothorax, the sides subparallel; apex gradually 

 rounded; humeral callus very moderate; grooves rather coarse, deep, 

 the intervals much wider than the grooves, each with a single irregular 

 series of moderate, well separated punctures, the third wider than the 

 others and confusedly, loosely punctate; setae very small, pale; abdomen 

 with very moderate and shallow, notably sparse punctures, the male 

 with a feeble basal impression, which is smoothly concave at the bottom. 

 Length (cf 9) 3-3-3-8 mm.; width 1.3-1.6 mm. Utah (Nephi), — 

 W'ickham. Three examples. 



Easily distinguishable by its rather small size, piceous color and 

 more or less sparse sculpture; from the next it dilTers also in the 

 nature of the abdominal impression of the male. 



Baris apposita n. sp. — Larger and rather stouter than the preceding, 

 nearly similar in coloration and lustre; beak arcuate toward base, closely 

 but not coarsely punctate, short, barely more than half the thoracic 

 length in the male; prothorax a fourth or fifth Avider than long, the sides 

 feebly converging and slightly arcuate to about apical fourth, then 

 strongly rounding, the basal lobe short, broadly arcuate, not abrupt; 

 punctures coarse, separated by less than their diameters, not much 

 coarser but dense laterally, the smooth median line narrow and long 

 though biabbreviated; scutellum very small, not as large as in the 

 preceding; elytra two-fifths longer than wide, formed nearly as in 

 nephiana but with more prominent humeral callus; sculpture nearly 

 similar; abdomen with larger, deeper and much more close-set punctures, 

 the male with a large and rather deep impression, the bottom of which 

 extends almost through the second segment and is rather acutely sulci- 

 form. Length (cf) 4.0 mm.; width 1.65 mm. Utah (Chadbourne's 

 Ranch), — W'ickham; also one female similar in size from Colorado 

 (Salida), New Mexico (Deming and Jemez Springs) and Texas (Long- 

 view) . 



This species is allied to the last but differs not only in its larger 

 size and different form of abdominal impression in the male, but in 

 the coarser and denser thoracic and abdominal sculpture, also in 

 the more elongate prothorax and relatively shorter beak. The 

 four females from as many rather widely separated localities, seem 

 to belong to the same species without any decided doubt; there are 

 no evident sexual difTerences in the beak. 



Baris immunis n. sp. — Form rather stouter, with more inflated elytra, 

 very convex, moderately shining,' black, with slight piceous tinge through- 

 out; beak arcuate and four-sevenths as long as the prothorax in the 

 male, rather closely but not very coarsely punctate basally; prothorax
