204 EMBRIK STRAND, 
notum nearly twice as broad anteriorly as long, slightly narrowed 
posteriorly, narrower than the head, slightly concave in the middle 
and on the sides of the anterior margin which is raised into a 
broad prominence in the middle and raised and produced at the 
anterior angles. Dorsal surface of the median segment no longer 
in the middle than the scutellum, the surface of the posterior trun- 
cation concave-oblique. Abdomen elongate, slightly narrowed at the 
base; the second dorsal segment opaque, transversely rugulose be- 
tween two low carinae, the apical carina separated from the raised 
apical margin by a broad groove; the apical half of the fifth ven- 
tral segment rugose. Pygidium vertically truncate posteriorly, the 
surface of the truncation ovate, the epipygium narrow, longitudinally 
grooved in the middle, rugulose, not reaching beyond the middle of 
the truncated surface, the surface of the hypopygium very finely 
obliquely striated. 
Black; a large mark on each side round the base of the an- 
tennae, a curved mark from the summit of the eyes extending 
beyond the posterior angles of the head and a broad longitudinal 
band on the sides of the abdomen from the base to the apex of the 
fifth segment yellow.

Nearest to avida Turn. but differs in the male by the shape 
of the scutellum and the broader median segment as well as in co- 
lour. The median segment of lateralis Kuuc is much shorter and 
broader. 
Elaphro»tera anisitsi n. sp. 
d. Mandibles bidentate, the outer tooth sharply pointed and 
long, the inner tooth short and very broadly truncate. Clypeus 
very broadly emarginate at the apex, the angles of the emargination 
produced into short spines, smooth and shining, with shallow punc- 
tures at the base, the apical half slightly concave. Maxillary palpi 
rather stout, the joints of almost equal length, except the basal 
joint which is short. Head broad, finely and very closely punctured; 
tlıe interantennal prominence broad, very shallowly emarginate at 
the apex, divided by a low delicate carina which reaches the an- 
terior ocellus. Thorax closely punctured, the pronotum very finely, 
mesonotum more strongly; scutellum convex, more sparsely punctured.
