344 HYMENOPTEEA. 



the top rounded ; above strongly punctured and sparsely covered with fuscous hair ; 

 the propleurse punctured. The abdomen is slightly wider than the thorax, shorter than 

 the head and thorax united ; the basal segment ferruginous, the apex fringed with 

 golden hair ; the second segment punctured, black, with a broad pale yellowish band 

 in the middle ; the other segments black, clothed with long black hairs ; the pygidium 

 clothed laterally with long pale hairs. The legs are covered densely with long pale 

 fulvous hair ; the femora black, the knees, tibiae, and tarsi testaceous. 



52. Sphaerophthalma gratiosa. 



Long, fere 5 millim. $ . 



Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 



Head wider than the thorax, rounded in front, distinctly concave behind ; the eyes 

 large, the part of the head behind them not half their length ; ferruginous, covered 

 with golden pubescence. The antenna? pale ferruginous, the apical two joints black ; 

 the scape curved, bare, the third and fourth joints subequal. The thorax ferruginous, 

 distinctly longer than the head, not much narrowed towards the apex, very slightly 

 contracted in the middle, the tubercle distinct; rounded in front, the apex with 

 an oblique slope, the sides tuberculate; above punctured and covered with golden 

 pubescence. The propleurse closely punctured. The abdomen longer than the head and 

 thorax united, sharply and gradually narrowed from the middle of the second segment 

 to the apex ; the basal segment pale ferruginous, the apex with a band of pale golden 

 pubescence ; the second segment black, and having a broad band of pale golden 

 pubescence in the middle ; the third segment black ; the other segments densely 

 covered with golden pubescence. The ventral segments pale ferruginous ; the apices 

 fringed with fulvous hair. The legs pale ferruginous, covered rather densely with 

 fulvous hair. 



In the coloration of the abdomen S. gratiosa agrees closely with S. minutoria, except 

 that the apical segments are densely covered with golden liair ; also differing from that 

 species in having the abdomen longer than the head and thorax united, the sides of 

 the median segment tuberculate, and the eyes very much larger. 



The following species have been described by Smith so imperfectly, that I am unable 

 to refer them to their proper section : —
