194 EMBRIK STRAND, 
rugose between two transverse carinae, the apical carina much higher 
than the basal and separated by a deep and broad groove from the 
strongly raised apical margin. Fifth ventral segment coarsely ru- 
gose. Pygidium vertically truncate posteriorly, the surface of the 
truncation much broader than long; the dorsal plate very short, 
broadly and deeply emarginate posteriorly and coarsely longitudinally 
striated; the lower plate produced anterior)y so as to fit into the 
emargination of the upper, then broadened sharply and produced 
on each side into a very short spine beyond which it is very broadly 
rounded, granulate at the base, very broadly smooth on the apical 
margin. 
Black; the concave space between the base of the antennae 
and the eyes dull luteous; the apical margin of the first dorsal seg- 
ment of the abdomen, the lower plate of the pygidium and the 
spines of the tibiae and tarsi fusco-ferruginous. 
Length 13 mm. 
Hab. Brazil. 
Received with E. amplipennis Sm. of which it may be the female. 
It can only be placed in Klaphroptera provisionally, the form of the 
pygidium being very different. 
Elaphroptera acuminata n. sp. 
(Bl. 11, Kin 14) 
2. Mandibles slightly elbowed, the outer tooth long, the inner 
one very short and obliquely truncate on the inner margin. Clypeus 
short and broad, produced in the middle of the anterior margin into 
a point, with a very feeble emargination on each side of the point; 
a small, convex, subtubercular eminence in the middle of the elypeus, 
which is finely punctured at the base, smooth and shining at the 
apex. Head closely and shallowly punctured, the interantennal pro- 
minence strongly bilobed, not broad, divided by a broad longitudinal 
suleus which extends more narrowly to the anterior ocellus, the 
whole head sparsely clothed with ceinereous pubescence Antennae 
longer than the head, thorax and median segment combined, inserted 
rather near together, the apical joints arcuate beneath, the second 
joint of the flagellum as long as the third. Thorax finely and closely 
punctured; the pronotum strongly rounded at the anterior angles, 
the anterior margin scarcely raised; scutellum moderately convex. 
Median segment longer than the mesonotum, narrowed posteriorly
