TEN NEW FIREFLIES FROM JAMAICA—BUCK y 
tarsi, and ventral surface of thorax medium brown, coxae and femora 
white, tibiae thinner and more cylindrical than typical in Photinus 
and Diphotus; both claws of all feet bifid, with the inner of the two 
points shorter than the outer (pl. 3, fig. 31); tibial spurs light brown, 
distributed front 2, middle 2, hind 2. Tergites 1 to 6 medium brown, 
7 and pygidium white laterally; pygidium ogival. Sternites 2 to 5 
medium brown, 6 and 7 white except for medium brown anterior 
border of 6; 8 and 9 with some light brown areas; hind margins of 6. 
and 7 only very feebly emarginate, that of 8 prolonged medially to a 
slender point, closely applied to and overlapping the slender 9 (pl. 2, 
fig. 20); photogenic organs as in no other known male Jamaican firefly 
(except P. lucernula Barber), confined to central half or third of 
abdominal sternites 6 and 7 (pl. 2, fig. 20, O, cross-lined). Aedeagus. 
(pl. 3, fig. 25, a-c) very different from that of any other known 
Jamaican firefly; wholly white; lateral lobes forming broad, dorso- 
ventrally flattened, horizontal, thin, warped blades nearly meeting 
in median sagittal line and concealing the median lobe almost entirely, 
curving ventrally along lateral margins and tapering gradually to 
sharply pointed apices which are directed posteroventrally and pro- 
vided with a few long chaetae; median lobe emerges from basal folded 
membranous collar as roughly cylindrical membranous mass, appar- 
ently with ventral functional opening, and bends dorsally near its 
apex to a point below the tips of the lateral lobes. 
Type and paratypes.—U.S.N.M. No. 57315. 
Distribution.—Morces Gap, July 16, 1941, type male and two para- 
type males.
