PANTOMORUS OF AMERICA NORTH OF MEXICO © 5 
at hand differ as a whole from those of the United States by having the 
- basal margin of the elytron more or less strongly, and often sharply, 
elevated. 
PANTOPLANES Schoenherr, 1840 
Pantoplanes Schoenherr, 1840, Genera et Species Curculionidum, v. 6, pt. 1, 
p. 111. Monobasic. Type, Naupactus anthribiformis Boh., 1833; type 
locality, Brazil. Species not at hand and status of genus uncertain. (See 
Chevrolat, Bull. Soc. Ent. France 1879: cxxx.) 
SYMMATHETES Schoenherr, 1847 
Symmathetes Schoenherr, 1847, Mantissa secunda Familiae Curculionidum, 
p. 31. Monobasic. Type, 8. kollari Schoen., ibid., p. 32; type locality, 
Brazil. Species not at hand, and status of genus uncertain. Schoenherr 
gives a combined generic and specific description, and both the generic 
and the specific names should be credited to him. 
ASYNONYCHUS Crotch, 1867 
Asynonychus Crotch, 1867, Zool. Soc. London Proc., p. 3888. Monobasic. Type, 
A. godmani Crotch, ibid., p. 389; type locality, island of Fayal, Azores 
Islands. Here revived as a subgenus of Pantomorus. 
Aramigus Horn, 1876, Amer. Phil. Soc. Proc. 15: 93. Type, Liparus tessellatus 
Say, 1824, designated by Pierce, 1913, U. S. Natl. Mus. Proc. 45: 416; type 
locality, Missouri. 
Aomopactus Jekel, 1876, quoted from letter of Jekel by Horn, Amer. Phil. Soc. 
Proe. 15: 94, footnote. This uncataloged name apparently was never 
published by Jekel, but it is validated by its association with Liparus 
tessellatus Say and “N. durius Germar” in the above-cited paper. Liparus 
tessellatus Say, 1824, is hereby designated type of Aomopactus Jekel, 1876, 
which thus becomes an absolute synonym of Aramigus Horn. 
PHACEPHOLIS Horn, 1876 
Phacepholis Horn, 1876, Amer. Phil. Soc. Proce. 15: 95. Type, P. elegans Horn, 
ibid., p. 96, designated by Pierce, 1918, U. S. Natl. Mus. Proc. 45: 416; 
type locality, “Kansas to Texas.” Here revived as a _ subgenus of 
Pantomorus. 
PANTOPACTUS Jekel, 1876 
Pantopactus Jekel, 1876, quoted from letter of Jekel by Horn, Amer. Phil. Soc. 
Proc. 15: 96, footnote. This genonym, as in the case of Aomopactus, has 
not been cataloged heretofore, but it is validated in the paper cited by its 
association with Phacepholis elegans Horn, Naupactus stupidus Boh., N. 
nobilis Boh., and N. crinitus Boh. The last three of these four species 
are Mexican and belong to Pantomorus sens. lat., but they do not seem to 
be properly referable to any of the named segregates of Pantomorus, ex- 
cept possibly to Athetetes. Champion, 1911 (Biologia Centrali-Americana, 
y. 4, pt. 3, p. 885), suggests that stupidus and uniformis belong to Phace- 
pholis, but in the species mentioned the basal margin of the conjoined 
elytra is slightly but sharply prominent, the dorsal comb of the hind tibia 
is longer, and the scape differently shaped and clothed. It appears de- 
sirable so to fix genotypes that Pantopactus Jekel will be available, if 
needed. Therefore, Nauwpactus stupidus Boh., 1840, type locality Alvarado, 
Mexico, is hereby designated type of Pantopactus Jekel. 
ATHETETES Pascoe, 1886 
Athetetes Pascoe, 1886, Ann. and Mag. Nat. Hist. (5) 17: 415. Monobasic. 
Type, A. globicollis Pascoe, ibid., p. 416; type locality, Mexico. In the 
type species the exaggeration of the male characters on the anterior parts 
of the body gives this sex a distinctive appearance, but in other respects 
Athetetes is doubtfully separable from Pantopactus.
