MR. J. S. BALT ON SOME GENERA 
one on each side near the outer border. Thorax about one half 
broader than long ; sides straight and slightly diverging from 
the base nearly to the apex ; anterior angle slightly produced, 
obtuse, hinder angle armed with an obtuse lateral tooth; upper 
surface impressed with a large, shallow, trilobate fovea, which 
covers nearly the whole central disk. Elytra parallel, convex ; 
each elytron with seven or eight distinct longitudinal costae, 
their interspaces finely punctured. 
I possess two specimens of this species, both belonging to the 
6 sex. 
2. Cynorta apicipennis. Subfiliformis, parallela, flava, oculis, elv- 
trisque apice nigris ; thoraee quam longo vix latiore, disco leviter 
trifoveolato ; elytris elevato-costatis, interspatiis punctatis. Long.

Fern. ? Antennis longitudine corporem paullo superantibus ; clypeo 
excavato, concavo. 
Hab. Sarawak {Wallace). 
Narrowly' elongate, parallel. Head strongly'- exserted ; clypeus 
concave, smooth ; maxillary palpi robust, the upper two joints 
conjointly ovate; antennae slender, filiform, longer than the body. 
Thorax rather broader than long ; sides slightly diverging and 
sinuate from the base to beyond the middle, thence converging 
towards the apex ; upper surface impunctate, impressed with a 
large shallow trifid excavation, which covers a considerable 
portion of the surface. Elytra parallel, sub cylindrical ; each 
with eight or nine longitudinal costae, their interspaces distinctly 
punctate. The abdomen in the only specimen before me is 
shrivelled, so that I am unable to decide with certainty as to its 
sex, but from the non-dilated basal joint of the anterior tarsus I 
believe it to be a female. 
3. Cynorta facialis. Subfiliformis, parallela, flava, oculis elytrisque 
apice nigris, abdominis apice nigro-piceo; thoraee quam longo vix 
latiore, disco lsevi, pone medium bifoveolato ; elytris parallelis, leviter 
elevato-costatis, interspatiis distincte punctatis. Long. 2| lin. 
Mas. Clypei dimidio postico trigonato, flavo, medio fovea rotundata 
impresso ; dimidio antico depresso, transversim concavo. 
Hab. Sarawak: a single specimen {Wallace) . 
Clypeus with its upper half not depressed, trigonate, its 
surface plane, impressed in the middle with a small round fovea ; 
the lower half strongly depressed and separated from the upper
