1914] Alexander—New or Little-known Neotropical Hexatomini oo 
Abra, Island of Luzon, on the Benguet Road during the construc- 
tion of that road. The location is definitely inland; the camp was 
in a deep canyon, where Dr. Graves wrote me “the Mountains 
are so high we see the sun only between 9 a. m. and 3 p.m.” The 
Benguet River runs through this canyon, and there is no sea or 
blackish water within many miles. These Anophelines were there 
in great numbers, the collection from which the specimens were 
_ sent to Mr. Theobald, containing about fifty specimens, all of 
them this one species. 
It is also of interest to note that for a while no other species were 
taken, although no effort was made to that end, and during that 
time malarial fever was very prevalent. 
This can only mean that M. Ludlowi may breed in fresh water, 
but this, by no means precludes its breeding also in salt or brackish 
water, for a sufficient number of other Anophelines are shown to 
breed indifferently in fresh or salt water to make it at least allow- 
able.to suppose that Judlowii may do the same. 
NEW OR LITTLE-KNOWN NEOTROPICAL HEXATOMINI 
(TIPULIDE, DIPTERA.) 
By Cuas: P. ALEXANDER, 
Ithaca, N. Y.! 
The following species were included in collections received for 
study from the American Museum of Natural History (Mr. Gross- 
beck); United States National Museum (Mr. Knab); Cornell 
University (Dr. Bradley); and the Muzeu Rocha (Senior Rocha). 
I express my sincere thanks to the above-named gentlemen for 
this and other favors received from them. The present paper 
deals with the Hexatomini, an extensive tribe of crane-flies, which 
reaches its maximum of specific development in the tropics. The 
study of these forms was conducted as research in Systematic 
Entomology at Cornell University under Dr. J. Chester Bradley, 
to whom I am indebted now, as before, for advice and many val- 
uable suggestions.
