STUDIES ON THE FIREFLY, IV: TEN NEW LAMPYRIDS 
FROM JAMAICA 
By Joun B, Buck 
BarBer’s (1941) key to the lampyrid fireflies of Jamaica contains 
brief descriptions of 38 new species and subspecies, mainly from my 
1936 collection. The purpose of the present paper is to describe 10 
additional species that were recognized in a much more extensive 
collection made in July and August 1941.1. Mr. Barber and I have 
in preparation a monograph that will include all previously published 
information on Jamaican fireflies, a revised key, and extensive data 
on the habits and distributions of the forms considered. We regard 
this latter type of information of very great importance for an ade- 
quate understanding of a lampyrid fauna. 
MATERIAL, METHODS, AND TERMINOLOGY 
The descriptions were made from dried and mounted specimens, 
although I tried to include as many characters as possible that can 
be seen in fresh samples or with a minimum of microscopical observa- 
tion. In many instances, however, a positive identification cannot 
be made without careful microscopical study of certain basic anatom- 
ical features, and for this a brilliant spotlight and a binocular dis- 
secting microscope with magnification up to 50 diameters are necessary. 
As emphasized by Barber (1941), the mode of preservation of fresh

of Comparative Zoology collection; to Miss Idolene Hegemann, of Bennington College, who made most of 
the aedeagus drawings; and to Dr. d’Alte Welch for lending the pocket aneroid barometer used for the alti- 
tude measurements. The expenses of the trip were met in part by a grant from the Penrose Fund of the 
American Philosophical Society. The expedition based at Clydesdale House in the Blue Mountains, for 
the use of which we are greatly indebted to the Natural History Society of Jamaica, to the Jamaica Depart- 
ment of Forestry, and particularly to C. Bernard Lewis, curator of the Science Museum of the Institute 
of Jamaica, who worked tirelessly to make our stay in Jamaica as profitable as possible. Finally, I want 
to thank especially H. S. Barber, who has given me unstinted guidance and encouragement in all aspects 
of the work. This study was meade in the Department of Zoology, University of Rochester, Rochester, N. Y.
