1946] Tabanidae of Colombia 71 
67. Basychela steinheili (Enderlein). Synonym: Dicladocera 
steinheili Enderlein, 1925. 
The type locality of this species is given as “Colombia: Bo- 
gota, Quindin.” This was evidently a misspelling of Quindio, a 
district in the northeastern corner of Valle del Cauca and the 
adjoining sections of Caldas and Tolima. — Not seen by us. 
*68. Basychela basirufa (Walker). Synonyms: Tabanus basi- 
rufus Walker, 1850; Dicladocera pallidetibia Krober, 1940. 
Cundinamarca : Guasca (E. A. Chapin). — Originally de- 
scribed from Colombia, without more definite locality. The 
hairy eyes and long antennal tooth, curved downward, refer the 
species to Dasy chela. 
*69. Basychela caloptera (Schiner). Synonym: Tabanus calop- 
terus Schiner, 1868. 
Magdalena: Cincinnati, Santa Marta (W. M. Mann). — 
Krober (1940) recorded this species from Colombia, without 
definite locality. 
70. Basychela (Stypochela) bogotana (Enderlein). Synonym: 
Stypockela bogotana Enderlein, 1922 and 1925. 
This species was originally described with the following lo- 
calities: “Columbien, Bogota, Cartago und Las Pavas — Piod- 
saa Molar.” Both Cartago and Las Pavas are in Valle del 
Cauca; the locality Bogota is probably erroneous, being merely 
the place from which the specimens were shipped to Europe. — 
Not seen by us. 
Alliomma Borgmeier, 1934 
Alliomma was proposed by Borgmeier (1934, Rev. de Ento- 
mologia, IV, pt. 2, pp. 222, footnote, and 269), with Ommallia 
thiemeana Enderlein as type, for Krober’s Ommallia of 1931 
(Rev. de Entomologia, I, pt. 3, p. 293). The type of Enderlein’s 
genus Ommallia (1923) is Ommallia viridis Enderlein, a species 
not congeneric with O. thiemeana and now placed in Cryptotylus. 
The name Alliomma should be used for a group of species more 
closely related to the subgenus Tabanus , proper, than to Diche- 
lacera . While these species agree with Dichelacera and Dasy- 
chela ( = Dicladocera of most authors) in the long, finger-shaped 
extension of the base of the first antennal segment, they differ 
by the subepaulet completely covered with macrotrichia. The 
eyes are bare.
