70 Psyche [Sept. -Dec. 
have united Stypochela with Dicladocera , were it not that Kro- 
ber found the type of 5. bogotana to have only three, instead of 
four, terminal annuli to the third antennal segment. The eyes 
are pubescent. 
63. Dasychela perplexa (Walker). Synonym: Tab anus per plexus 
Walker, 1850. 
This species was originally described from Colombia, without 
more definite locality. Krober (1940) redescribed the type. — 
Not seen by us. 
*64. Dasychela macula (Macquart). Synonyms: Tabanus ma- 
cula Macquart, 1845; Tabanus auribarbis Macquart, 1848; 
Tabanus argyrophorus Schiner, 1868; Tabanus submacula 
Walker, 1850. 
Magdalena: northwestern Sierra Nevada de Santa Marta (P. 
Darlington) ; San Lorenzo Mts. (reported by Krober, 1940). — 
Valle del Cauca: La Cumbre (Collector?). — T. submacula 
Walker was originally described from Colombia, without defi- 
nite locality. Surcouf (1919) recorded T. auribarbis from the 
Valley of the Magdalena River. 
Krober (1940) includes also Tabanus scutellatus Macquart 
(1838) among the synonyms of D. macula. Specimens from 
southern Brazil, before us, agree perfectly with Macquart’s 
description, but are very distinct from D. macula. Among other 
points, the eyes are completely bare, which places the species in 
the subgenus Psalidia. Moreover, what Ad. Lutz reported from 
southern Brazil as D. macula , appears to have been mostly, if 
not always, D. scutellata (Macquart). 
65. Dasychela acheronitens (Krober). Synonym: Dicladocera 
acheronitens Krober, 193 lg. 
The original description was made partly on specimens from 
Colombia, without more definite locality. — Not seen by us 
from Colombia. 
66. Dasychela limbativena Enderlein, 1922. Synonym: Diclado- 
cera limbativena Enderlein, 1925. 
The type locality of this species is given as “Colombia: Bo- 
gota, Guayabal.” This Guayabal is most probably in Valle del 
Cauca. Bogota appears to be in this case merely the locality 
from which the specimen was shipped to Europe. — Not seen 
by us from Colombia; but we studied a female from Ecuador.
