the black ; but the tibiae are distinctly white, the two basal segments of the abdomen 

 pallid lemon-white, and the metanotum behind is not so much excavated.

 Long. 14 millim. 



Hab. Panama, Bugaba 1 , Volcan de Chiriqui 2500 to 3000 feet (Champion). 



Face pallid yellow (perhaps discoloured), marked with some scattered microscopic 

 punctures ; clypeus broad, sharply transverse, the sides rather acute ; labrum and the 

 apex of the mandibles black ; the top of the head is entirely black, and the black 

 extends, as a triangular prolongation, nearly to the base of the antenna?. Mesonotum 

 shining, impunctate, almost glabrous. Scutellum broad, flat, keeled at the sides, 

 which bear a yellow mark ; the top with a few punctures. Metanotum distinctly 

 areolated, punctured, very slightly excavated behind. Postpetiole, the second segment, 

 and the basal three fourths of the third segment, longitudinally striated above, the sides 

 punctured and with a conspicuous keel; apical segments impunctate. The third 

 segment bears a large black mark, contracted at the apex in the middle ; the 

 following segments are entirely black. The four anterior knees are only black 

 behind ; the posterior knees entirely so, there being double the amount of black on 

 the femora that there is on the tibiae ; on the front pair it is much less. The black 

 cloud is present in both wings ; the areolet is sharply triangular above. 



The specimen from the Volcan de Chiriqui wants the black on the third abdominal 

 segment, and the black on the hind knees scarcely extends on to the femora.
