majority of the species discussed at this time were included invery large collections of crane-flies that were taken in Mexico,
British Honduras and Guatemala by my friend Dr. Alfons M.
Dampf, Government Entomologist for Mexico. Other importantserieswere collected by Dr. John Myers and Mr. Fred W. Walker,
the types of the latter being included. in the Museum of Zoiilogyof the University of Michigan. One additional specieswas collected by Mr. J. J. White and rvas given to me by Dr. Crampton.
I wish to express my sincere appreciation an<l thanks to the entomologists nameil. Except where stated to the contrary, the typesof the novelties are preserved in my collection.

G. (I'.) proliristsllus agreesmost closely with G. (L.) scimitar
Alexander, from which it differs especially in the much longer
and more slender inner dististyle and the entirely pale phallosome. G. (L.) producta Alexander has a very similar innerclististyle but the apical lobe of the basistyle is greatly produced
into a long fleshy lobe.
