TEN NEW FIREFLIES FROM JAMAICA—-BUCK 63 
A short mention (‘‘Field Characters”) of certain prominent charac- 
teristics heads each description. This is intended only as an aid to 
preliminary identification, not as a key or diagnosis. 
The numbers following the individual descriptions refer, unless 
otherwise noted, to the U. S. National Museum collection, where the 
specimens are deposited. 
LOCALITIES 
Studies on intra- and interspecific relationships, such as the work 
on Photinus evanescens Barber (1941) already mentioned (Buck, 1942), 
require precise knowledge of geographical distribution. Since most of 
the localities visited in 1941 were in very inaccessible semiwilderness 
regions, a brief description of each, alphabetically arranged, is included. 
Some of the mentioned place names refer to those on the map of 
Jamaica prepared by the Public Works Department and issued by 
the Jamaica Automobile Association, but the names of some of the 
more obscure localities can be found only on manuscript maps in the 
Institute of Jamaica. The name in parentheses after the place name 
is that of the parish. For a better understanding of the geography 
of the high peaks of the Blue Mountain Range, where much of the 
collecting was done, it should be stated that the main ridge runs 
roughly west-east, with John Crow (6,000 feet), Bellevue (6,000 feet ?), 
Sir Johns (6,100 feet), High (6,300 feet ?), Mossmans (6,600 feet), 
and Blue Mountain (7,360 feet) Peaks in sequence. 
Belmore Castle (Trelawny): In the southern Cockpit Country at the end of 
automobile transportation on the road leading north from Golden Grove 
(St. Elizabeth), and about 19 airline miles northwest of Mandeville. Col- 
lections were made along the forest trail running north toward interior 
banana plantings, and also around the ranger station at Quickstep, one mile 
to the south. Altitude about 1,500 feet. 
Catherines Peak (St. Andrew): 5,050 feet, southern outlier of main Blue Moun- 
tain Range, about 2% airline miles east-southeast of Hardware Gap and 
11 airline miles northeast of Kingston. Collected trail from Woodcutters 
Gap (4,500 feet) to summit. 
Chestervale (St. Andrew): Coffee plantation in foothills of John Crow Peak, 
near junction of Yallas and Clyde Rivers about 2 airline miles east-northeast 
of Catherines Peak. Altitude 3,200 feet. 
Clydesdale (St. Andrew): Abandoned coffee plantation near the headwaters of 
the Clyde, 1 airline mile east of Chestervale with which it is connected by 
2 miles of excellent rain-forest trail, much used for collecting. Altitude 
3,500 feet. 
Cornpuss Gap (St. Thomas): Collected along trail leading up east side of the 
east fork of the Island River Valley starting about 3 trail (2 airline) miles 
north of Bath, at 1,650 feet at point 0.8 trail mile north of United Fruit Co. 
shed at Barretts Gap, and continuing up 2 miles through banana plantings 
to forest reserve at about 1,975 feet. 
Morces Gap (Portland—St. Andrew): Between John Crow Peak on the west and 
Bellevue Peak on the east. Altitude 4,950 feet.
