TEN NEW FIREFLIES FROM JAMAICA—BUCK 67 
PHOTINUS NOTHOIDES, new species 
PLATE 1, FiGuRE 3; PLATE 2, Figure 14 
Field characters —Length 5.5, width 1.8 mm. Pronotum and 
elytra dark brown with white borders, which coincide in the humeral 
region to give the impression, not well shown in the photograph, of 
a continuous border around body. 
Male.—Pronotum 1.0 by 1.5 mm.; approximately semicircular in 
front, side margins straight and slightly convergent apically in basal 
third, hind margin slightly emarginate, hind angles acute; disc marked 
in basal half with a large, approximately rectangular, homogeneous, 
dark brown spot, which is produced slightly in the middle of its an- 
terior margin and surrounded on side and front margins by a white 
border of about one-sixth pronotal width. Scutellum and mesonotal 
plates dark brown. Elytron 4.5 by 0.9 mm.; widest at basal sixth, 
tapering slightly to apical fifth, thence more sharply in both margins 
to rounded apex; dark brown (darkest at humerus) with lateral white 
border of about one-fifth elytral width extending to apical sixth, no 
sutural border. Head width 0.9 mm. Eye length 0.5 mm. Frons 
width 0.37 mm., dark brown at antennae, black above; slightly con- 
cave; interocular margins very divergent (about 30°). Maxillary 
and labial palpi light to medium brown. Antennae 1.7 mm., basal 
two segments medium brown, rest dark brown, segments 6 to 8 each 
between once and a half and twice as long as wide. Ventral surface 
of thorax dark brown; all coxae and femora and the entire hind leg 
white, tibiae and tarsi of front and middle legs medium brown; claws 
white; no tibial spurs visible (too small?). Tergites medium to dark 
brown; pygidium damaged. Sternites 2 to 4 dark brown, 5 partly 
darkened anteriorly, 6 to 9 white; 5 sinuate, 6 to 8 strongly notched 
in middle of hind margins. Aedeagus (pl. 2, fig. 14, a-c): lateral lobes 
white, laterally flattened and internally hollowed basally, truncated 
apically to sharp posteroventrally directed tips which curve evenly 
to contact with each other; dorsal internal margins of lateral lobes 
well separated and with three scallops; median lobe dorsoventrally 
flattened, expanded to a pair of lateral teeth at about half, then curv- 
ing steeply dorsoposteriorly to project between the lateral lobes and 
end dorsal to their apices in a sharp point; infuscate dorsal covering 
of median lobe medium brown in middle third, otherwise white; 
median lobe almost entirely membranous ventrally. 
Type.—U.S.N.M. No. 57318. 
Distribution.—Catherines Peak, July 25, 1941, type male. Named 
for its superficial similarity to Photinus nothus Barber.
