354 COLEOPTERA. 
a few rugae or punctures near each, mesial groove almost entire. Elytra 
oblong-oval, more narrowed near the base than behind, their shoulders 
obsolete and but little broader than’the base of thorax, their whole length 
quite twice that of the thorax ; each with 8 series of moderately fine distant 
punctures ; these are a little more irregular but only slightly coarser near 
the sides, but become rather coarser and more irregular near the apex ; 
interstices nearly plane, with some fine aciculate impressions which become 
more distinct behind. 
Underside shining. Head more irregularly rugose than the prosternum. 
Terminal abdominal. segment with a single puncture at each side of the 
middle, at its extremity. 
Legs rather stout, and, like the antennae, quite normal. Eyes prominent. 
The nearest species, M. aeneoniger (1453), is more brilliant and slender 
and considerably more attenuate posteriorly; the elytral punctation is 
more irregular and remote, and the 5th and 6th series are obsolete ; it, 
moreover, has very obvious rugae on the forehead.

Clipping’s, about seven miles north-east of Kingston. One caught 
running on a track during bright sunshine by Mr. T. Hall on the 28th 
January, 1914. 
3789. Mecodema gratum sp. nov. 
Elongate, narrow, moderately convex; glossy aeneo-niger, antennae, 
tarsi, and palpi piceous, terminal joints of these last rufescent. 
Head, including the moderately prominent eyes, as broad as the thoracic 
apex, usually indistinctly longitudinally striate in front, distinctly punctured 
behind the eyes, with irregular interocular rugae, the epistome widely 
emarginate. Thorax subelongate, yet hardly any longer than broad, base 
and apex widely but not deeply emarginate, lateral margins narrow, not 
crenulate, very gently curvedly narrowed backwards, more, but not at all 
abruptly, narrowed towards the nearly straight sides of the base, with 
subrectangular angles there; basal fossae moderately deep and elongate, 
the intervening space punctate, the rest of its surface smooth, dorsal groove 
hardly attaining the apex. Elytra double the length of thorax, rather 
wider than it is at the base ; each elytron with 8 series of rather fine, mostly 
elongate, unequal punctiform impressions; these usually become finer 
towards the sides but coarser behind; between the 7th and 8th there are 
2 or 3 larger punctures behind and another near the base; interstices 
smooth but not at all sharply defined, the lateral space nearly smooth but 
with some larger punctures near the margin. 
Underside “closely and rugosely punctate near the sides, mesosternum 
wholly so, abdomen less distinctly, its terminal segment with some well- 
marked transverse striae and bipunctate near each side of the apex. 
Outer angles of anterior and middle tibiae only moderately prominent, 
the posterior simple ; last 6 joimts of antennae thinly pubescent. 
This is undoubtedly distinct from M. erraticum, being not only much 
smaller and more cylindrical, but also differently seulptured. The thorax 
appears more elongate, and is without longitudinal sulci at the base or the 
apex, its fossae are deeper and more elongate, its sides are simple, and the 
elytral sculpture much more irregular. Sometimes there are a few indis- 
tinct punctures near the front angles of the thorax.
