 tudinal line to pronotum black or piceous; abdominal segments

 stout, second joint less than one-third the length of first joint, 

 remaining joints mutilated in type; anterior area or lobe of

Hab. Upper Burma; North Shan Hills (J. C. Brown). 



Two apterous forms received from Burma, by the structure 

 of the head undoubtedly belong to Jucundus. They differ 

 from the type J. custodiendus in having the antennae more 

 robust, the anterior pronotal area or lobe a little longer, and 

 by the anterior tibiae being more robust and dentately amp] iate 

 at apex.
