RECORDSAND DESCRIPTIONSOF TROPICALAFRICAN CRANE-FLIES(Tipulide, Diptera)
By
CHARLES P. ALEXANDER.
MassachusettsAgricultural College,Amherst, Massachusetts,U. S. A.

PART I
During the past few years, the writer has been privileged to
study the extensive collections of African crane-flies contained in
the principal Museums of America, Europe and South Africa.
The result of this study has been a vety great increase in our
knowledge of the Tipuloidean fauna of the Ethiopian Region. In
the present report are included the descriptfons of a tetfi/ newforms belonging to the Museum of the Belgian Congo and to thewriter. Records of certain insufficiently known species are also
included. I would express my deep gratitude to the numerous
entomologists who have coopercted in this study, among $/hom I
would especially mention Drs. Joseen and Mrcnrr Bnqu.e,enr,Dr. H. Scnoutroru of the Congo Museum, Mons. E. Sicuv of
the Paris Museum, Mr. F. W. Eowanos of the British Museumof Natural History, Dr. R. A. DuMrvrsnand Mr. H. K. Munno.

Madagascar: Tananadve, 1916 (Wlrenror); Paris Museum,
The accompanyingnotes on the habits of theseflies by my friendand colleague,Mr. H. K. Munno, are given:n This species is fairly widespread in South Africa, but in myexperience it appears to be more particulaily a < high-veld rr form.
That is to say, it is much more abundant in the open plateauof theTransvaal (3ooo-5ooo feet) than in the lower coastal forest belt.
Even in the high veld I have not found it numerousamong trees andbushes but the localities it especiallyfavors are along small streams
away from trees. Here it often occurs in great numbers among therank grass,the more so when the stream or u spruit , is in a furrowcausedby water erosion and hence is more or less protected from thewind. The specliescanbe found throughout the summer, but is mostnumerous in Decembet and Januaty.
Males arc tnvaiably more numerous than the females, and, inlarge swarms of the insects,only a few females are to be found, eachhaving severalmales in atendance.The insects (males)are quiet andrcmain resting on the grass,with the wing folded over the abdomen.
When disturbed, however, they fly off quickly. The only times I
have observedfemales, they have been clinging to grass stems withmalesdancing about, ,H. K. Muxno.
