4. Hectarthrum cylindricum. 



Black : the head has the usual deep channels which charac- 

 terise this genus ; two deep channels originating at the basal angles 

 of the clypeus, run upwards, meeting a little before the vertex, 

 thence passing off at right angles they continue, reaching the inner 

 margins of the eyes, here becoming narrower they traverse the inner 

 margins and curve round, meeting the origin of the deep sulcation ; 

 the clypeus has a deep fossulet in the centre, the lateral margins of 

 which are raised : the joints of the antennae in the female are about 

 one-third longer than broad, slightly narrower towards their base ; 

 in the male they are quadrate, having the angles rounded, as seen 

 from above ; the thorax elongate, having a marginal stria crossing 

 at the base, from each angle of which a parallel stria is continued 

 forwards to the anterior margin, which is continued on each side a 

 short distance towards the centre : the elytra have a deep sutural 

 stria from base to apex, continued along the outer margin up to the 

 shoulder; a central stria runs at about an equal distance from the 

 sutural and marginal striae ; near to this towards the base is an ab- 

 breviated stria.
