 Lucas, Baja California. 



Oxacis pallida Lee. (Asclera) Proc. Phil. Acad., 1854, 

 p. 224. 



Paler piceous, sparsely pubescent. Antennas piceous. 

 Maxillary palpi with terminal joint cultriform, obtuse at 

 tip, and distinctly longer than the preceding joint. Head 

 pale with frontal piceous area, surface moderately coarsely 

 punctate and alutaceous. Thorax distinctly longer than 

 wide, sides arcuate in front, obliquely narrowed poste- 

 riorly, disc regularly convex, moderately closely punctate 

 and alutaceous, color reddish yellow, with a median short 

 piceous vitta and a small spot each side. Elytra piceous, 

 the suture, side -margin, (more widely) and the costas 

 paler, these latter well marked, surface moderately closely 

 punctate, with short not dense pubescence. Body beneath 

 piceous, finely, densely punctate, and finely pubescent. 

 Legs pale, outer half of femora piceous. Length .34 

 inch. ; 8.5 mm. 



A well marked species easily known by the distinct- 

 ness of the elytral costas in which it agrees with the next 

 two species, but from which it may be known by the 

 palpus and other characters. 



Occurs in Texas. 



Oxacis sororia n. sp. 



Entirely pale testaceous, subopaque, with rather coarse 

 pubescence. Antennas pale. Last joint of maxillary 

 palpus cultriform, obtuse at tip, and not longer than the 

 preceding joint. Head coarsely and closely punctate. 

 Thorax nearly as wide as long, sides arcuate in front, 

 then obliquely narrowing to base, disc convex, densely 

 punctate, sometimes with a smoother median line. Elytra 

 rather coarsely and closely punctate, the discal costas
