sides of the prothorax, longer elytra and less coarse interstitial 

 punctuation; molesta occurs at an unrecorded locality in Arizona. 

 Illex Csy., occurs at Alamosa, Colorado, and at Marysvale, in 

 Utah. I have now three examples of pectorosa Lee, taken at 

 St. Louis, Missouri by Schuster and at the White Sulphur Springs, 

 West Virginia, by Robinson; the anterior coxae are separated by 

 one-half more than their own width, the sternal surface between 

 them fiat, and it was described originally as from Texas; it is 

 recorded from Connecticut by Blatchley, but possibly in subspecific 

 form. 



The following three small species are allied to the southern 

 Calif ornian arguta: 



Onychobaris oblita n. sp. — Oblong-suboval, moderately convex above, 

 slightly shining, piceous-black, the legs and beak rufous; beak in the 

 female strongly arcuate, moderately punctate and longer than the pro- 

 thorax, the latter a fourth wider than long, the sides parallel and straight, 

 rounding at about apical third and oblique thence to the briefly sub- 

 tubulate apex, which is half as wide as the base; punctures strong and 

 dense, the median line obliterated; basal lobe small but rather prominent, 

 the scutellum smooth, small and evidently transverse; elytra two-fifths 

 longer than wide, evidently wider than the prothorax and fully three- 

 fourths longer, the sides feebly converging and slightly arcuate, gradually 

 rounding about the apex, the humeral callus very moderate; grooves 

 deep ; intervals one-half to once wider than the grooves, each with a single 

 line of sHghtly separated moderate punctures, coarser and denser toward 

 the sides and sometimes confused at base; setae small but evident; 

 abdomen closely, rather strongly punctate, more loosely toward the 

 middle. Length (9) 2.25 mm.; width 0.9 mm. CaHfornia (southern), 

 — Dunn. 



Differs from arguta in its smaller size, less prominent humeral 

 callus, smaller and more abruptly formed thoracic basal lobe and 

 rufous legs and beak, these being deep black in both my repre- 

 sentatives of arguta. 



Onychobaris cernua n. sp. — Oblong-suboval, rather strongly convex 

 and feebly shining, black, the legs and beak rufous, the pronotum piceo- 

 rufous; beak in the female shorter, arcuate, somewhat closely punctulate, 

 barely as long as the prothorax, the latter a fourth wider than long, the 

 sides parallel and only just visibly arcuate, rapidly rounding in apical 

 fourth to the briefly subtubulate apex, which is slightly more than half 

 as wide as the base; punctures deep, not very coarse, notably dense 

 throughout, without smooth median line, the basal lobe short, broadly 

 rounded, the scutellum small, ogival and somewhat transverse; elytra 

 scarcely two-fifths longer than wide, as wide as the prothorax and barely
