Derocalymma clavigera, sp. n. 



Long. Corp. 15 millim. ; long. pron. 9 millim. (jun.), 

 10 millim. ; lat. pron. 6 millim. 



Female. — Clay-coloured. Eyes rather wide apart. Sides 

 of the protiotum slightly raised, not sulcated ; a madian carina 

 in front. Pronotum, except at the sides, with numerous 

 longitudinal rugosities and granules ; two transverse rows of 

 large granules, the first interrupted in the middle before the 

 extremity. Meso- and metanotum with three rather irregular 

 rows of large granules, the largest at the extremity. The 

 extremity of each of the abdominal segments bears, except on 

 the edges, a row of very large granules, not very close together, 

 as if studded with nails. This is preceded on each segment 

 by one or two rows of smaller and closer ones. Even the 

 rounded terminal plate bears two short rows o£ large tubercles. 

 Cinder surface dark brown, with greyish tomentuni, but 

 without tubercles. The smaller specimen is more reddish, 

 especially beneath.
