Joppa melanostiqma Cam. in Biol. Centr. Amer. Hym. 195, 8. 

 (Tab. 9, fig. 10.) 



Diagnose wie oben. (Die Abbildung stellt ein 9 vor.) 

 „Hab.: Panama, Bugaba, Volcan de Chiriqui, 2500 to 3000 feet 

 (Champion). 



Face pallid yellow (perhaps discoloured), marked with sorae 

 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 

 triangulär Prolongation, nearly to the base of the antennae. Meso- 

 notum 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 im- 

 punctate. 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 trian- 

 gulär above. 



The specimen from the Volcan de Chiriqui wants the black on 

 the third abdominal segment, and the black on the bind knees 

 scarcely extends on to the femora.

 which bear a yellow mark", die Abbildung zeigt aber das Schildchen
