1946] Tabanidae of Colombia 67 
53. Dichelacera (Dichelacera) rufipennis (Macquart). Synonym: 
Tabanus rufipennis Macquart, 1838. 
This species was originally described from Brazil. In 1845, 
Macquart referred to it a female from New Grenada, which may 
have meant Colombia. Whether this specimen was cospecific 
with the type seems doubtful. — Not seen by us. 
54. Dichelacera (? Catachlorops) nigripalpis (Macquart). Syno- 
nym: Tabanus nigripalpis Macquart, 1845. 
This species was originally described without definite local- 
ity from “the temperate regions of New Grenada,” which may 
have meant Colombia. The description is rather vague as to 
the shape of the antenna, the third segment having a “pointe 
assez forte.” Krober (1931), who never saw it, placed it tenta- 
tively in Catachlorops. — Not seen by us. 
*55. Dichelacera (Catachlorops) testacea Macquart, 1846. 
Meta: Restrepo (J. Bequaert) ; Villavicencio (M. Bates).— 
Vaupes: between San Jose de Guaviare and Calamar (A. Gast). 
— Originally described from Colombia, without more definite 
locality. 
56. Dichelacera (PCatachlorops) quadrimaculata (Macquart). 
Synonyms: Tabanus quadrimaculatus Macquart, 1845; Taba- 
nus poecilopterus Schiner, 1868. 
T. quadrimaculatus was originally described without definite 
locality from “New Grenada,” which may have meant Colombia. 
— Not seen by us. 
*57. Dichelacera (Catachlorops) rufescens (Fabricius). Syno- 
nym: Tabanus rufescens Fabricius, 1805. 
Magdalena: Vista Nieve, Sierra Nevada de Santa Marta (H. 
Viereck). 
*58. Dichelacera (Catachlorops) transposita Walker, 1854. 
Colima: La Brea (S. Renjifo). — Valle del Cauca: Puerto 
Merizalde, Rio Naya (S. Renjifo). — This species was origi- 
nally described from the “West Coast of America,” which may 
possibly have been in Colombia. 
*59. Dichelacera (Psalidia) vespertina, new name. Synonym: 
Tabanus elongatus Macquart, 1846; not of Wiedemann, 1828. 
Choco: Rio Nimiquia (E. Osorno and J. Boshell). — Cundi- 
namarca: Bogota (B. Guevara. — This locality needs to be 
confirmed). — Meta: Villavicencio (G. Fairchild); Restrepo
