dibusque obscure testaceis ; elytris punctorum seriebus duabus, 
singulis stria suturali, antice abbreviata, impressis. Long. 14 
millim. 
Nearly black; the head pitchy. Thorax (when seen under a 
microscope) sparingly punctured. Elytra with an impressed sutural 
stria, only visibly punctured when seen under the microscope; paral- 
lel to this stria is a row of punctures, a little further removed from 
the stria than the stria is from the suture ; there is a second row of 
punctures, but it is not quite so distinct as the first.

ABLECHRUS, gen. nov. 
Eyes entire, not very prominent. Antennze inserted in front of 
the eyes, of 9 joints, the Ist joint short obconic; the 2nd as long as 
broad; 3rd as long as the first, a little rounded at its base; 4th and 
5th as long as the 3rd, subcylinarical; the 6th and 7th a little 
shorter ; the 8th one third longer than broad, narrowed at its ex- 
treme base; the 9th joint one third longer than the 8th, elongate- 
ovate, subacuminate at the apex. Thorax convex, transverse, 
rounded at the sides and behind. Elytra at their base not broader 
than the thorax, but somewhat suddenly widened below the shoulders, 
ample posteriorly, rounded at the apex. 
This insect closely resembles Hbeus thoracicus in form; the 
structure of the antennze, however, is quite different, and unlike any 
genus of Melyridee with which I am acquainted. Its position would 
be near Hbeus. 
ABLECHRUS FLAVIPES, sp. 0. 
fEneus, nitidus, vix pubescens; thorace transverso, cum elytris 
sat crebre evidenter punctato, his thorace fere triplo longiori- 
bus, basi thorace haud latioribus, postice ampliatis, apice ro- 
tundatis; antennis flavo-testaceis, articulis tribus apicalibus 
infuscatis ; pedibus flavis. Long. 2 millim., lat. 1 millim. 
General form that of Hbeus thoracicus, but smaller and relatively 
a trifle shorter; thorax rather convex, a little narrowed in front, 
very finely margined at the sides and posteriorly, distinctly and 
rather thickly punctured. Scutellum distinct. Elytraat their base 
not broader than the thorax, but immediately becoming broader and 
rounded posteriorly. Legs yellowish; the posterior tibiz slightly 
curved ; apex of tarsi slightly infuscated.
