for which I had waited patiently for three long years. The next 
day I had to leave for my new laboratory at Tjustrup, and when 
I returned I found no more specimens. Still the animal could now 
be identified and the observations be published. 
The Imago. 
In 1891 Lynch-Arribålzaga founded the genus Tænio- 
rhynchus including three species: Culex tæniorhynchus Wiede- 
mann, T. confinnis Arribålzaga and T. fasciolalus Arribålzaga. 
Theobald (1901) supposed, that C. fæniorhynchus Wiedemann 
Was erroneously identified and that it was really identical with C. 
titillans Walker, which Arribålzaga cites as synonym of C. tænio- 
rhynchus Wiedemann. He proposed the name Panoplites for titil- 
lans and used the name Tæniorhynchus for T. fasciolatus Arri- 
bålzaga. Then the name Panoplites was found to be preoccupied 
and was therefore changed to Mansonia by Blanchard (1901). 
In 1915 Howard, Dyar, and Knab maintain, that the two gen- 
era Mansonia and Tæniorhynchus are not distinct, and the spec- 
ies were referred to the genus Mansonia. 
According to Giles (1902), Blanchard (1905), and H.D.K. 
(1912—17), the home of the genus Mansonia is almost entirely 
restricted to the tropical or subtropical countries. The main local- 
ities are Brasilia, West-Africa, the neighborhood of the great Afri- 
can lakes, India, China and West-Australia. According to H. D. K. 
North-America possesses only two species, M. ochropus Dyar and 
Knab and M. perturbans (Walker) Dyar. In about 1900 European 
dipterologists show, that the genus also occurs in Europe, and that 
a single species lives far beyond the normal area of distribution. 
In 1896 Ficalbi describes a mosquito from Italy under the name 
of Culex Richardii. Theobald (1901 p. 194) refers the species 
to the genus Tæniorhynchus and remarks: "Ficalbi's 7'. Richardii 
comes in this genus in spite of the male ungues differing from 
those of Arribålzaga's species" (1901, p. 190). According to Theo- 
bald (1901 p. 197) a single specimen of this species was found in 
England near Sutton of Bradley and, probably, the species also 
Occurs at Toronto (Canada); finally in 1903 (p. 269) Theobald 
States that the species "seems to be common in some parts of the 
Norfolk Broads, England".
