350 HYMENOPTEEA. 



long oblique slope ; the second segment punctured, sparsely covered with long fuscous 

 hair, the base in the middle black; the other segments fringed with pale golden 

 pubescence and bearing also long pale hair. The legs are ferruginous ; the knees and 

 tibial spines blackish, the calearia ferruginous and black. 



This species somewhat resembles S. sumichrasti in general coloration; but the 

 pubescence is distinctly golden, the head is smaller and is much less developed behind, 

 the third antennal joint is shorter compared to the fourth, the pronotum and the base 

 of the mesonotum are not covered with long fulvous hair, and the second abdominal 

 segment wants the two spots of golden pubescence.

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



The head with the eyes wider than the thorax, slightly rounded in front and behind ; 

 covered densely with a pale golden pubescence ; the eyes much longer than the part 

 of the head behind them. The scape of the antennae covered with white hair ; the 

 flagellum stout ; the third joint not one-quarter longer than the fourth. The thorax 

 elongate, more than twice the length of the head, gradually narrowed from near the 

 base to the apex, the latter having a gradually rounded oblique slope ; coarsely punc- 

 tured, sparsely covered with black hair, the median segment with a broad band of 

 silvery pubescence ; the mesopleurse covered with silvery pubescence ; the metapleurae 

 coarsely reticulated. The abdomen is black, shorter than the head and thorax united ; 

 the basal segment is very coarsely punctured, sparsely covered with long white hair, 

 the base oblique ; the second segment is punctured, but not so strongly as the first, 

 covered with long black hair, towards its apex are two round pale yellow marks ; the 

 apical segments are covered all over with pale pubescence. There is no keel on the 

 basal ventral segment. The legs are black, very sparsely covered with pale hair ; the 

 tibial spines and the calearia black.

The head a little narrower than the thorax, rounded in front and behind, densely
