Somewhat related to the European M. rustica, Linn., but 
the antennze are much longer than in that species, the clypeus 
less strongly emarginate, the puncturation coarser, and the 
humeral cell more contracted.

Q. Nigra; antennis dimidio basali, palpis, abdominis segmento 
tertio sequentibusque, valvulis terebra, pedibusque, coxis ex- 
ceptis, fulvo-ferrugineis; mandibulis basi, oculorum orbitis in- 
ternis late, abdominisque segmento secundo fusco-ferrugineis ;

Long. 16 mm. ; terebree long. 6 mm. 
?. Head strongly narrowed behind the eyes and towards 
the clypeus ; cheeks long, about equal in length to the fourth 
antennal joint. Mandibles narrowed to the apex, ending in 
two very small teeth. Clypeus broadly truncate at the apex, 
closely and minutely punctured and clothed with fuscous 
hairs ; face coarsely punctured-rugose. Antenne inserted 
nearly as far from the anterior ocellus as from the apex of the 
clypeus, 39-jointed, scape produced beneath so as to form a 
partial sheath for the second joint; the third joint the 
longest, the fourteen basal joints fulvo-ferruginous, the an- 
tenn gradually thickened to about the twentieth joint. 
Front and vertex finely rugulose, the space above the base of 
the antennze smooth and shining and feebly concave. ‘horax 
opaque, very closely and rather strongly punctured ; the 
pleuree rugosely punctured, with a broad oblique band on the 
middle ot the mesopleure smooth and shining. Median 
segment coarsely punctured-1ugose; the spiracles large and 
elongate, enclosed in an elongate triangular lateral area; on 
each side of the dorsal surface of the segment at the base is 
an area enclosed by the upper side of the lateral area, the 
base of the segment, and a curved caiina which reaches the 
base a little on the outer side of the middle. Abdomen 
rather indistinctly microscopically punctured; first segment 
petiolate, the spiracles nearer to the apex of the segment than
