250 HYMENOPTEEA. 



tuberculated at the base laterally, white, the apex of the postpetiole also white, as wel 

 as the ventral surface. Lobes of the pronotum prominent ; there is a white mark on 

 either side of the mesonotum at the tegulae. On the sternum and on the front of the 

 mesopleura the reddish-fulvous colour merges into yellow. Areolet nearly square, the 

 nervures bullated in front. Coxae punctured, the four anterior ones yellow in front ; 

 the hinder femora at the extreme base and apex, the apices of the tarsi, and the extreme 

 base also of the hind ones, black.

 Long. 15 millim. 



Hab. Guatemala, San Geronimo (Champion). 



Antennae as long as the body, the fulvous ring broad. Face closely punctured ; 

 clypeus projecting at the apex ; vertex wrinkled. Mesonotum punctured, irregularly 

 striated ; lobes of the pronotum projecting ; pleurae irregularly striated and punctured. 

 Sutures of the mesonotum deep. Scutellum much broader than long, strongly punc- 

 tured. The prosternum is fulvous behind, and the line on the pronotum is moderately 

 broad, and does not reach the tegulae ; the middle lobe of the mesonotum is edged with 

 fulvous at the apex, and the pleural tubercles are white. Metanotum black to the 

 tubercles (which are not clearly denned) ; the upper transverse keel straight, in front 

 of it the surface is irregularly wrinkled, shining, and marked with two roundish white 

 marks, in front of it coarsely and irregularly reticulated, the apex transversely striated ; 

 the lower transverse keel not defined. Petiole longish, narrow, not separated clearly 

 from the postpetiole, the base fulvous, the apex white. Hind coxae punctured at 

 the base and apex ; anterior coxae yellow in front ; hind spurs, the base of the hind 

 and the apices of all the tibiae, black. Wings short. 



Obs. It is possible that the ring on the antennae, the face, and the edge of the 

 pronotum are really white, the fulvous tint being, perhaps, owing to discoloration.
