A low blunt irregular carina runs from the orbit nearly to the posterior margin; below this a spine on either side; a short antennal spine on the anterior margin. Blade of antennal scale exceeding the spine. Hands of first pair of feet from three and a half to four times as long as the width of the palm. The anterior margin forms an angle of about forty-five degrees with the side margins. First to fifth abdominal seg- ments furnished with a sharp median carina; sixth seg- ment with two sharp carinae, which toward the posterior end become lower and may disappear altogether in front of the posterior margin.
