Gen. MACEOMOEPHUS, Chaud., 

 Bull. Mosc, 1857, ii., p. 61. 



Mentum very little excavate, the median tooth tridentate, with the 

 median tooth longer than the other two, and as long as the lateral 

 lobes, which are narrow, acute at the tip, slightly diverging internally, 

 rounded outwardly, and with a deep long impression on each side of 

 the base ; last joint of the maxillary palpi moderately compressed 

 and truncate, the penultimate one of the labial palpi longer than the 

 others, last joint short, rounded at tip and truncate ; labrum short, 

 bisinuate, the median part subtruncate, three deep punctures, one in 

 the centre of the median part and one on each side ; head quadi^ate, 

 projecting slightly in front of the eyes, the gense moderately de- 

 veloped in a small tubercle behind the eyes ; antennae short, hardly 

 reaching the median part of the pro thorax, the first joint claviform, 

 nearly as long as the three following ones ; prothorax elongato- 

 quadrate ; elytra cylindrical, with the humeral angles moderately 

 dentate ; anterior tibiae moderately digitate, intermediate ones with 

 three teeth, the apical one much longer than the others ; median part 

 of the abdominal segments very faintly bipunctate. 



Macromoephus elongatus, Chaud., 



Plate IX., fig. 1. 



Bull. Mosc, 1857, ii., p. 62. 



Black, subopaque ; head as broad as long, sinuate above the eye, a 

 little emarginate in the lateral part of the anterior angle, forehead 

 with two moderately deep impressions, slightly plicate and reaching 

 the median part, posterior part of the head smooth ; prothorax as 

 long as broad, truncate at the apex, not dentate in the posterior 

 angle, slightly sinuate in the median part of the outer sides, median 

 part of the base not produced behind, the sides of the base very 

 slightly oblique, smooth, with the usual median longitudinal and 

 apical transverse lines, the basal one hardly defined, but ending in a 

 faint impression at each end ; elytra twice as long as the prothorax, 

 not broader, cylindrical, with the humeral angle projecting a little, 

 convex, nonstriate on the disk, with the intervals not raised, the 

 seventh stria distinct, and the eighth interval somewhat more convex 

 in the basal part, where it overhangs a little the outer margin, than 

 in the posterior part, outer margin with a series of distant punctures ; 

 two punctures (on one side only) in the posterior part of the sixth 

 stria in my unique example ; anterior tibiae unidentate above the 

 digitation. Length 33 -mm. ; width 8 mm. 



The cylindrical facies of this species is very peculiar. 



I am indebted to Mons. E. Oberthur for an example of this very 

 rare species, originally belonging to the collection of the late H. W. 

 Bates, and labelled Cradock (South Africa).
