List of Species 
A canthocera longicornis (Fab.) (Tabanus), 1 77 5 > Syst. Ent., 
p. 790, Brasilia. 1794, Ent. Syst., IV p. 371. Brasilia Mus. Dom. 
Banks. The species should date from 1775, not x 794> as given by 
Wiedemann and most subsequent authors. The descriptions are iden- 
tical. I did not see the type, which should be in B.M., but is ap- 
parently lost. The species is the type of A canthocera Macq. 1834. 
Catachlorops rufescens (Fab.) (Tabanus), 1805, Syst. Antliat., 
p. 100, Amer, Merid. Dom. Smidt Mus. de Sehestedt. The single 
type (C.) is intact though faded and dusty. It is labelled “T. 
rufescens ex Am: Mer: Schmidt”. Scutellum white-haired and white 
transverse bands on at least second to fourth abdominal tergites. Legs 
entirely dark. Beard, pleura and venter of abdomen entirely dark- 
haired. Labella large and wholly sclerotized, palpi slender, brown, 
black-haired. I give here figures of wing and head structures 
(Fig. 1). Krober’s (1939) C. rufescens is entirely different, while 
the type of his C. scuteliatus in British Museum agreed closely with 
notes and figures of type of rufescens Fab. (New synonymy ) . 
Chlorotabanus inanis (Fab.) (Tabanus), 1787, Mantissa Insect. 
II, p. 356. Cajennae Dom. v. Rohr. The name should date as above 
not 1794 as given by subsequent authors. Philip and Fairchild 
(1956) have discussed the material in Copenhagen, which consists 
of but the pin and labels of the original specimen (K.) and another 
specimen (C.) in fair condition det. by Fabricius from Amer. Merid. 
Chrysops costatus (Fab.) (Tabanus) 1794, Ent. Syst. IV, p. 373, 
without locality; 1805, Syst. Antliat. p. 112, in America meridionali 
Dom. Smidt. Mus. Dom Lund. There are three specimens (C.) 
all in good condition, one of which is labelled type. This agrees with 
current interpretations. One of the others is C. ecuadoriensis Lutz 
or a related form. The name has been shown to be a synonym of C. 
variegatus (De G.). 
Chrysops laeta Fab. 1805, Syst. Anti., p. 112, in America merid- 
ionali Dom. Smidt. Mus. Dom. Lund. Philip (1955) has dis- 
cussed the types and shown that laeta auct. is not Fabricius’ species. 
There are 3 specimens, two (C.) in good condition, the other (K.) 
represented by wings only. The specimen described as tuxeni by 
Philip is formosa Krob., (New synonymy ) while the Kiel specimen 
is probably C. varians var. tardus Wied. True laeta differs from 
most allied species by the much shortened discal cell. Specimens in
