NO. 1988. STUDIES OF NORTH AMERICAN WEEVILS— PIERCE. 419 



PANTOMORUS (PHACEPHOLIS) METALLICUS, new species. 



Described from four specimens from Onaga, Kansas (Wickham)- 

 Another specimen from Kansas is also at hand. 



Length 6 mm., width 2.5 mm. Very similar to elegans in form 

 and color, from which it differs mainly by having the median tibiae 

 minutely denticulate. The nasal plate is triangular but very deeply 

 emarginate and more nearly resembles that of viridis than of elegans. 



It is possible that future collecting will connect this Kansas form 

 as a race of one of the Texas species. 



Type.— Cat. No. 14651, U.S.Nat.Mus. 



PANTOMORUS (PHACEPHOLIS) TEXANUS, new species. 



Described from two specimens from Texas (C. V. Riley collection). 

 A tliird specimen is at hand labeled Kansas. 



Length 7 mm., width 3 mm. This species is of the color and form 

 of candidus Horn but differs so strongly in the antennal characters 

 that it seems necessary to separate it. It is of course possible that 

 these represent the two sexes or two races of a species intermediate 

 as to antennal structure. The funicular joints are all very elongate, 

 and the second is considerably longer than the first and also than 

 the third and fourth combined. The nasal plate is very small, and 

 strongly arcuate on both margins. 



Type.—C&t. No. 14652, U.S.Nat.Mus. 



The Kansas specimen is a male and has several tubercles in the 

 second ventral segment. 



PANTOMORUS (PHACEPHOLIS) CANDIDUS Horn. 

 Phacepholis Candida Horn. 

 The nasal plate is very small, convex, and strongly emarginate. 

 The males have a row of tubercles on the second ventral segment. 



PANTOMORUS (PHACEPHOLIS) PALLIDUS Pierce. 

 Phacepholis pallida Pierce. 

 The nasal plate is tiny, triangular and strongly emarginate. In 

 this species the strial punctures vary from minutely setigerous to 

 squamigeroQs. The material studied is from Corpus Christi, Wades, 

 Beeville, Sharpsburg, Brownsville, and San Antonio, Texas. Speci- 

 mens from King-sville, Texas, May 12, 1912 (E. E. Scholl), were 

 recorded as injurious to cotton. The male has a row of minute gran- 

 ulations on the second ventral segment. 



PANTOMORUS (PHACEPHOLIS) OBSCURUS Horn. 

 Phacepholis obscura Horn. 

 The nasal plate is tiny, triangular and emarginate. The vestiture 

 of the strial punctures also varies in this species in the single series 

 from Mineral WeUs, Texas, in the same manner as in preceding species. 

 The ventral segment in the male has a row of small tubercles.
