I describe the south-american species which I have mentioned 
in my Monograph: 
Rhamphidia albitarsis n. sp. 
Reddish-brown, abdomen darker; a darker line in the middle 
of the thoraeie dorsum; legs pale-brown, distal half of the tarsi 
white; wings subhyaline, with a slight brownish shade in the apical 
portion; stigma distinet, pale brown, rather narrow. The rostrum 
is a little longer than the head, infuscated at tip; antennae and 
palpi brown (I cannot see the color of the base of the antennae). 
Length about 6—7 mm. 
Hab. Porto Rico (Moritz); a single male in the Berlin Museum. 
This species faithfully reproduces the characters of the european 
Rhamphidiae. The venation is the same; the marginal crossvein 
absent; the submarginal cell is in contact with the discal, so that 
the small cerossvein is wanting; this last character, however, is pro- 
bably variable (comp. Monogr. etc. p. 104). 
I abstain from describing another species in the Berlin Museum 
(a single female; Brazil) because it seems to me that the end of the 
rostrum is broken of{. The venation is somewhat different from that 
of the preceding species; the discal cell larger, the second vein 
shorter, the small crossvein present etc. The color is yellow, the 
tips of the femora are brown. — 
Elephantomyia. 
O. Sacken, Proc. Acad. Nat. Sc. Phil. 1859, p. 220; id. Monogr. 
etc. IV, p. 106, Tab. 1, f. 5 (wing); 3, f. 8 (forceps). 
At the time of the publication of my monograph a single north- 
american species and three species, included in the prussian amber, 
were known. Since then a species, apparently identical with the 
N. American F. Westwoodi, has been discovered in Europe (near 
Münich: compare my article: A relic of the tertiary period in Europe; 
in the Mittheil. d. Münchener Entom. Ver. 1881, p, 152—154). 
Among the specimens from Caffraria, brought home by Wahl- 
berg, and which I saw in the Museum in Stockholm, there is an 
Elephantomyia, which as far as I saw, agrees in all the generic 
characters with the N. American species, even in the characteristie 
absence of the marginal crossvein. In the British Museum I saw a 
piece of copal from the eastern coast of Africa, which contains half 
a dozen specimens of Elephantomyyia. 
At present therefore ‚Elephantomyia is known to occur in Europe 
(apparently very rare), N. America, Southern Africa (both alive and 
semi-fossil in copal) and in the prussian amber.
