JOPPA. 197 



base, the apex flat, the upper surface covered with scattered microscopic punctures ; 

 postscutellum smooth, shining, impunctate ; the thorax on either side of it reticulated. 

 Metanotum impunctate, the apex a little excavated in the middle ; the area? distinct. 

 Postpetiole and the second and third segments longitudinally striated above, smooth, 

 ivith scattered punctures along the sides ; base of the fourth segment obscurely striated, 

 the apex slightly punctured; apical segments with scattered punctures, and densely 

 pilose. Sheath of the ovipositor densely pilose. On the anterior femora the black is 

 only behind, on the posterior femora it extends all round. As in most of the species, 

 the yellow on the legs tends to change to fulvous.

Hah. Costa Rica, Cache x (Rogers) ; Panama, Bugaba 800 to 1500 feet (Champion). 



This species is readily known from J. macuUcomis by the femora being entirely 

 yellow, by the areolet not being triangular at the top, the lateral nervures but slightly 

 converging above, and by the abdomen being perfectly smooth, and not in any way 

 striated.

Hal. Guatemala, Sabo in Vera Paz 1 (Champion); Panama, Volcan de Chiriqui 1 

 (Champion). 



Head with scattered punctures, aciculated on the top ; mandibles and palpi yellow. 

 Mesonotum with scattered punctures, semi-opaque ; pleura? rugose, longitudinally 

 striated, except in the centre of the mesopleura, which is shining, impunctate. 

 Scutellum sharply gibbous, acute at the top, the sides keeled, the space between 

 the keel and the raised central peak hollow. Metapleura transversely striated. 

 Abdomen entirely longitudinally striated above. The anterior femora are black, 

 except at the base and apex and a small part of the middle in front; the inter- 

 mediate femora have the apical three fourths, and the posterior pair a little more 

 than the apical third, bluish-black. The four anterior tibise are bluish-black behind, 

 the posterior tibiae entirely yellow. Generally the part of the wing between the base 

 and the apex of the stigma is hyaline, and there is usually a hyaline spot in the black 

 basal part. The hind wings are only smoky at the apex. Mandibles, palpi, and a 

 spot on either side of the clypeus, yellow.
