{Somewhat related to the European M. rustica, Linn., but 

 the anteimge are much longer than in that species, theclypeus 

 less strongly emarginate, the puncturation coarser, and the 

 humeral cell more contracted.

2 . Nigra ; antennis dimidio basali, palpis, abdominis segmento 

 tertio sequentibusque, valvulis terebra^, pedibusque, coxis ex- 

 ceptis, fulvo-ferrugiueis ; maudibulis basi, oculorum orbitis in-

Long. 16 mm. ; terebrse long. 6 mm. 



? . Head strongly narrowed behind the eyes and towards 

 theclypeus; 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 clothtd with fuscous 

 liairs ; face coarsely punctured-rugose. Antennas 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 shuuh lor the second joint; the third joint the 

 longest, the fourteen basal joints fulvo-ferruginous, the an- 

 tennae gradually thickened to about the twentieth joint. 

 Front and vertex finely rugulose, the space above the base of 

 the antennae smooth and shining and feebly concave. Thorax 

 opaque, very closely and ratiier strongly punctured ; the 

 pleurae rugosely punctured, with a broad oblique band on the 

 middle of the mesopleur^e smooth and shining. Median 

 segment coarsely punctured-rugose; 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 j)unctured; first segment 

 petiolate, the spiracles nearer to the apex of the segment than
