200 Dr, Malcolm Durr’s rrdiminary Revision of the 
IMesonotum transverse, posterior margin truncate ; sides not keeled, 
but raised with blunt, tumid ridges converging posteriorly. 
Metanotum strongly concave posteriorly, almost entirely covering 
the first abdominal segment. 
The whole of the thoracic plates are dull black and densely and 
finely punctulate. 
Prosternum is double as long as wide, jiarallel. 
Mesosternum and metastern uni somewhat broader than long, the 
posterior margin truncate ; sternal plates reddish black and densely 
and finely punctulate. 
Legs typical, femora slender, black, yellow at the base and apex, 
long and slender. 
Tibiae long and slender, yellowish. 
Tarsi yellowish, long and slender. 
The second segment elongate and cylindrical, nearly as long as the 
third ; the first is longer than the second and third combined. 
Abdomen typical, of same colour and sculpture as the rest of the 
body, passing to reddish beneath; lateral tubercles on 3rd and 4th 
segments faint. 
Last dorsal segment very short and transverse, but narrower than 
the abdomen ; posterior margin naiTowed, and concave in the 
middle, leaving a short triangular lobe in each side projecting 
slightly over the forceps. 
Penultimate ventral segment short and broad, very obtusely 
rounded. 
Pygidium short, very narrow and compressed. 
Forceps with the branches remote at the base, cylindrical, tapering, 
straight at first, gently arcuate towards the apex.

Cacao, April 19 (Leg. Schwarz and Barbar) (in

This species has a superficial resemblance to M. nigra. 
It differs however in the generic characters, namely, the 
non-keeled mesonotum; the 4th-Gth antennal segments 
are much shorter, the pronotum longer, and the neck 
distinct. 
It is more difficult to distinguish from L. punctata, 
Dubr., from Java, but is smaller, slenderer, and the 
sculpture finer, the antennal segments shorter. 
It is not quite so small as N.'philetas, Burr, from Ceylon, 
the pronotum is much longer and not parallel, and the 
mesonotum has no strong transverse depression. 
I cannot compare it with Verhoeff’s two African species,
