NO. 1988. STUDIES OF NORTH AMERICAN WEEVILS— PIERCE. 403 

 PANDELETEIUS HELARIS Herbst. 



New material has been studied from Mobile, Alabama, April 18 

 1910, on Quercus, W. D. Pierce; Natchez, Mississippi, June 15, 1909 

 E. S. Tucker; Trinity, Texas, March 20, 1907, on Quercus pJiellos, 

 Pierce and Cushman; Beaumont, Texas, March 18, 1908, on Quercus 

 aquatica, E. S. Tucker. 



PANDELETEIUS DENTIPES, new species. 



Described from two specimens collected in the Chisos Mountains, 

 Brewster County, Texas, June 10-12, 1908, Mitchell and Cushman. 



Dark brown mottled with black, of the size and stature of hilaris. 

 Length 4-4.5 mm. Beak flat, apically truncate, with medially 

 impressed line; scrobes oblique passing beneath very close to eyes, 

 funicular joints elongate. Prothorax as long as wide, convex, strongly 

 arcuate at sides, constricted immediately in front of base and at one- 

 third from apex; coarsely but not closely punctate, scales mottled 

 without definite pattern. Elytra distinctly wider than thorax at 

 base, feebly rounded to apex. Anterior tibiae strongly sinuate on 

 inner margin and coarsely denticulate mth about 14 denticles. 

 Anterior coxae not more widely separated than the median coxae. 

 Undersurface closely covered with brown iridescent metallic scales. 



This species may be easily differentiated from all of the others by the 

 characters given in the table. 



Type.— Cat. No. 14653, U.S.Nat.Mus. 



PANDELETEIUS DEPRESSUS, new species.

 specimens are in the United States National Museum collections. 

 » Mottled grey, with markings almost as in hilaris. Length 5.5 mm. 

 Beak concave, apicaUy triangularly emarginate with triangular 

 smooth space and with medially unpressed line; scrobes arcuately 

 oblique passing beneath at a distance from the eyes; funicle seven- 

 jointed, last five funicular joints moniliform. Prothorax wider than 

 long, convex, strongly arcuate at sides, constricted near apex and 

 base, moderately punctate, scales mottled grey to black with a broad 

 median band; elytra distinctly wider than prothorax, sides straight, 

 sHghtly diverging to apical fourth, thence oblique to apex; anterior 

 tibiae slender, shghtly sinuate, bent at apex, denticulate withm; 

 anterior tarsi unusually long and slender, almost as long as tibiae, the 

 last joint equahng the three preceding. Anterior coxae separated
