134 HYMENOPTEKA. 



Eab. Panama, Bugaba 800 to 1500 feet (Champion). 



Antennae short, thick, becoming gradually thicker towards the apex, almost glabrous ; 

 second joint as long as the fourth ; third as long as the fourth and fifth together, these 

 with the sixth subequal ; seventh a little shorter ; ninth longer than the eighth or tenth ; 

 last shorter than the preceding joint, and not clearly separated from it; the scape reddish,, 

 the flagellum dark ferruginous, becoming lighter in tint towards the apex. Head a 

 little broader than the thorax, finely rugose; thorax above finely and closely rugose; 

 pronotum margined behind, broadly rounded and projecting behind, narrower in front* 

 and separated from the mesonotum by a ridge. Scutellum rounded behind, a little 

 projecting, the sides in front hollowed and striated. Mesonotum reticulated, the 

 transverse carina produced into a sharp spine in the middle. Pleurae striated. 

 Petiole much longer than broad, about one half of the length of the posterior coxae ; a 

 distinct ring at the basal third. Abdomen smooth, shining, ovate, the apex acute, not 

 forming a " cauda ;" second segment longer than all the others together ; the middle 

 segments more or less blackish ; ovipositor scarcely projecting, the tip black. There 

 are some bristles on the head, pronotum, and mesonotum; the head and meso- 

 notum covered with a white depressed pile. The wings at the base are irregularly 

 clouded at the commencement of the ulna, there is a cloud at the cubitus and a smaller 

 one on the opposite side, and the apex is hyaline, the rest fuscous.

 Long. 11 miUim., terebra 24 millim. 



Eab. Nicaragua, Chontales (Jansori). 



Antennae nearly as long as the body; the scape sharply compressed on the lower 

 side, curved, and with a short pedicel as long as the third joint at the base; the second 

 joint is twice as long as broad, narrow at the base, becoming gradually thicker towards 

 the apex, which is obliquely truncated ; third joint longer than the fourth, which is 

 much longer than the fifth ; the rest get gradually shorter ; the last conical, oblique ; 

 the basal joints are compressed, the apical less so, but still not cylindrical. The face 

 is covered with white pubescence ; the front below the antennae depressed, hollow. 

 The head, mesonotum, pleurae in front, and breast finely punctured. Meso- 

 pleurae shining, obscurely striated, this portion being separated from the rest by a 

 groove, which originates near the tegulae, goes round in front, curves round and
