Derocalymma bipapilla^ sp. n. 



Long. corp. 20-22 millim. ; lat. pron. 13 millim. 



Female. — Black; head small, punctured; eyes moderately 

 ajtproximating ; pronotum broad, the lateral lamella3 longi- 

 tudinally convex both above and below ; a broad gutter on 

 the inner side of the rim above, extending to the front margin, 

 where the approximating ends are separated by a siiort longi- 

 tudinal carina. The pronotum is thickly punctured, and 

 about the middle of the gutter is a large raised tubercle on 

 each side. The back of the pronotum is raised into a 

 crescent directed forwards; the front of this is less thickly 

 punctured, but the enclosed segment of a circle behind very 

 thickly. Here, and on the remaining segments of the thorax 

 and abdomen, wc find interrupted traces of a central carina. 

 The sides of the meso- and metanotum are flattened and re- 

 curved, and the segments of the abdomen are subdentate on 

 tiie lateral edges. The abdomen is thickly cribrate-j)unctate, 

 and there is a row of large granules on each side of the meta- 

 notum and of all the segments of the abdomen except the last, 

 before the extremity. Cerci black ; terminal plate obtusely 

 angulated.
