B. clavipes occurs all over North-America, north of Mexico, 
from Newfoundland to California and from Florida to Oregon. The 
oceurrence in Brazil (two specimens so labelled in the Vienna Museum) 
requires confirmation; compare O. S. Catal. N. Am. Dipt. 1878, 
p. 361). 
Tanyderus. 
Philippi, Verh. Z. B. Ges. 1865, p. 780, Tab. 29, f. 57. 
In the Verh. Z. Bool. Bot. Ges. 1879, p. 517—522 I have given 
a detailed description of this genus and of its next relatives, and 
have added a new species from New Zealand to it. I am able now 
to add a third species, as well as some details concerning the species 
from New Zealand. 
1. Tanyderus pictus Philippi, 1. e. — Chili. 
2. Tanyderus forceipatus O. Sack. ]. c. Male, — New Zealand. 
A male and a female from Otago, N. Z. kindly communicated 
by Capt. F. W. Hutton show very little difference from my descrip- 
tion. They are smaller (about 9—10 mm. long) and the brown spots 
on the wings are more intense, especially in the female; those along 
the apex are confluent and form a continous brown border. The 
female, as I antieipated (l. ec. p. 518 at the bottom), does not have 
the horny, pointed ovipositor, characteristic of the Tipulidae; the 
ovipositor, like that of Bittacomorpha, consists of a pair of small 
coriaceous valvules. The heads of my specimens are injured, so that 
I cannot complete my former statements about the antennae and the 
palpi. I have also seen male and female specimens in the Museum 
in Oxford. 
3. Tanyderus ornatissimus. — Amboina. 
Oylindrotoma ornatissima Doleschall, Natuurk. Tijdschr. Nederl. 
v. Indie, Deel XVII, p. 80, 1858. 
I have been able to examine a female of this species in the 
Vienna Museum, and thus to ascertain its true systematic position. 
I possess besides a copy of an original colored figure of a male 
drawn by Doleschall, but never published. From these data I am 
able to complete his insufficient description. 
As to the generic characters, the agreement with the two pre- 
ceding species is very great; difference in the venation is unim- 
portant.
