214 EMBRIK STRAND, 
space between them punctured rugulose, a very broad groove 
between the second carina and the raised apical margin. Pygidium 
vertically truncate, the surface of the truncation elongate ovate, 
almost smooth, the epipygium produced into a long point which does 
not reach the apex of the hypopygium. Fifth ventral segment rugose. 
The basal third of the posterior tibiae slender, the apical half 
widened and compressed. 
Black; the mandibles, flagellum, legs and pygidium fuscous; a 
broad transverse band on the middle of the first, third and 
fourth abdominal segments, emarginate posteriorly on the third and 
narrowly interrupted on the fourth and a spot on each side of 
the second segment between the carinae orange yellow. 
Length 12 mm.

2 &d, 12. Type in British Museum. 
Not very nearly allied to other species of the group, from 
which the female differs in the longer and narrower thorax, the 
very feebly excavated pronotum, the very strongly compressed 
median segment and the shape of the posterior tibiae. The male 
is much more strongly pubescent and the clypeus is less strongly 
emarginate and more porrect at the apex than in other species of 
the lateralis group. 
Elaphroptera inferna n. sp. 
(Bl, Bie. 12) 
3. Closely and finely punctured, most finely on the median 
segment, most coarsely on the abdomen and mesopleurae Clypeus 
broadly and shallowly triangularly emarginate at the apex, the 
mandibles strongly elbowed, bidentate, acute at the apex, the inner 
tooth short and blunt. Antennae longer than the thorax and median 
segment combined, the apical joints slightly arcuate; the scape, head, 
thorax, median segment and sides of the abdomen clothed with long 
black hairs. Pronotum short, very little narrower than the head, 
the anterior margin slightly raised; a transverse depressed row of 
deep punctures at the base of the scutellum. Median segment 
rounded, with two parallel longitudinal furrows at the apex. 
Abdomen elongate, tapering at the extremities, flattened and 
narrower than the thorax, the segments with a depressed transverse 
line close to the base; the first segment with a deep longitudinal 
furrow from the base to the middle. Seventh dorsal segment
