Vienna labelled types are those studied by Wiedemann, and not, of 
course, true types. They are varians var. tardus. C. tenuistria Krob., 
whose type is lost, is very probably a synonym of laeta Fab. (new 
synonymy). 
Chrysops tristis (Fab.) (Tabanus) 1798, Ent. Syst. Suppl., p. 567* 
Cajennae Dom. v. Rohr. Of the type (K) only the name label 
remains. Two others specimens (C.) are in the collection, one of 
which bears a Lectotype label by Philip. Although not strictly types, 
these specimens were surely studied by Fabricius and Philip’s action 
seems justified in the interests of stability, especially since subsequent 
workers have applied the name to at least 3 other species. I have 
an agreeing specimen from Surinam. 
Chrysops moerens (Fab.) (Tabanus) 1787, Mantiss. Insect. II. 
p. 356 Cajennae Dom. v. Rohr. The type now consists of a single 
wing (K.). It is not a Neotropical species and is discussed elsewhere 
(Fairchild, 1966 in press). 
Diachlorus bicinctus (Fab.) (Tabanus) 1805, Syst. Antliat. 
p. 102, America meridionali Dom. Smidt. Mus. Dom. Lund. The 
single type (C.) lacks one wing. It agrees with current interpreta- 
tions, and is type of the genus. 
Diachlorus curvipes (Fab.) ( Haematopota) 1805, Syst. Antliat., 
p. 107. America meridionali Dom. Schmidt. Mus. Dom de Sehestedt. 
There are 2 females labelled type (C.) in good condition, and 
another (K.) not labelled type lacking head and abdomen. The two 
types agree with current interpretations, the other specimen is too 
damaged for certainty, but is probably the same. 
Diachlorus podagric, us (Fab.) (Haematopota) 1805, Syst. Antliat. 
p. 108. America meridionali. Dom. Smidt. Mus. Dom. de Sehestedt. 
Two females (C.) labelled type in good condition. The type of D. 
nigrithorax Krob. 1930 in British Museum agrees with my notes on 
podagricus, and I believe is a synonym, (new synonymy). Neither 
Krober (1928) nor Lutz (1913) recognized the species. 
Dichelacera cervicornis (Fab) (Tabanus) 1805, Syst. Antliat. 
p. 100. America meridionali. Dom. Smidt. Mus. Dom. Lund. Two 
females in good condition (C.) are labelled types, another (K.) 
lacks head and abdomen, but is probably the same. All agree with 
current concepts (Fairchild and Philip i960). 
Dichelacera damicornis (Fab.) (Tabanus) 1805, Syst, Antiliat. 
p. 1 01. America meridionali. Dom. Smidt. Mus. Dom. Lund. Two 
females in fair condition (C.) are labelled types. Another (K.) con- 
sists of but 2 legs and the wings. The types are as treated by Fair- 
child and Philip (i960) ; the Kiel specimen is probably the same.
