PHOTINUS PARDALIS, new species 
PuaTte 1, Figure 2; Puate 2, Figure 12 
Field characters.—Length 6.5-7.0 mm., width 2.5 mm. Pronotum 
uniform white; elytra light brown with many small, irregularly dis- 
tributed, sometimes confluent, diffuse dark brown spots. 
Male.—Pronotum 1.3 by 1.9, 1.6 by 2.2, and 1.6 by 2.2 mm. in the 
three known males; front margin semicircular, lateral margins at 
hind angles varying from parallel to definitely convergent anteriorly; 
color uniform white, including disc, but with translucent area over 
eyes; hind margin nearly straight; hind angles prolonged slightly 
backward. Scutellum dark brown. Mesonotal plates usually light 
brown. LElytron averaging 5.4 by 1.2 mm.; light brown with about 30 
small irregular diffuse, sometimes confluent, dark brown spots; dull; 
darker at humerus; nearly parallel-sided to apical fourth, then tapering 
mainly in lateral margin; vestiture pale. Head width 1.3mm. Eye 
length 0.7 mm. Frons width 0.37 mm., black, slightly concave; 
interocular margins parallel. Maxillary palpi dark brown labial palpi 
light brown. Antennae 3.0 mm., dark brown, segments 6 to 8 each 
once and a half to twice as long as wide. Legs and ventral surface of 
thorax dark brown; claws light brown; tibial spurs very pale and 
inconspicuous, distributed front leg 1, middle leg 2, hind leg 2. Ter- 
gites 1 to 4 light brown, 5 to 8 white; pygidium broad and bulbously 
ogival, widest at basal third, hind margin produced centrally to blunt 
point. Sternites 2 to 4 dark brown, 5 to 9 white; 6 slightly, 7 and 8 
abruptly notched in center of hind margins; sternites project laterally 
considerably beyond corresponding tergites. Aedeagus (pl. 2, figs. 
12, a-c) nearly identical with that of P. lewisi but with two differences: 
the lateral surfaces of the tip of the median lobe and the internal sur- 
faces of the tips of the lateral lobes are toothed, and the ventrobasal 
sclerotized margins of the median lobe are expanded into small knobs. 
Female.—Fully winged; 8.4 by 3.5 mm.; more oval than male. 
Anterior margin of pronotum slightly blunter than in male, 1.9 by 
2.8 mm., lateral margins parallel in basal half, basal margin straight. 
Elytron 6.5 by 1.8 mm.; antennae 3.0 mm. Coloration as in male 
except that sternite 5 is partly white. Photogenic organ in median 
half of sternite 6. 
Type and paratypes.—U.S.N.M. No. 57317. 
Distribution.—Belmore Castle, August 9, 1941, type male and 1 
female paratype; Stony Hill, August 18, 1941, 1 male paratype; half 
a mile east of Stony Hill, February 10, 1937 (E. A. Chapin, collector), 
1 male paratype. 
Named for its spotted elytra, unique among known Jamaican 
lampyrid fireflies.
