 Long. 16 millim. ; terebra 5 millim. 



Hab. Panama, Volcan de Chiriqui 4000 to 6000 feet (Champion). 



Antennae longer than the body, the third joint nearly as long as the two succeeding 

 joints together. Head closely punctured ; vertex broadly depressed in front of the 

 ocelli. Pro- and mesonotum opaque, very closely punctured ; pleurae and scutellum 

 more shining and with the punctures more widely set apart. Metapleura coarsely 

 rugose ; metanotum coarsely transversely striated. First abdominal segment more than 

 double as long as wide, longitudinally punctured, the base and apex shining, impunc- 

 tate, the base hollowed in the centre ; there is a distinct shining tubercle on either 

 side of the middle of the segment. The other segments punctured, the punctuation 

 becoming finer towards the apex ; the apices shining, almost impunctate. The anterior 

 tibiae and femora are testaceous in front ; the tibiae reddish, the stiff pile with which 

 they are covered being also reddish; spurs reddish. Areolet slightly pedunculate 

 above ; the recurrent nervure received in the apical third. 



The wings vary in tint, the hind portion being usually lighter than the front. The
