HYMENOPTEROUS FAMILY STEPHANID.E. 737 



Black to dark brown, cheeks sometimes pale marked. Wings 

 infumate. 



Length 25-39 mm. ; terebra in 2 ) 38-52 mm. 



Habitat : Brazil ; Guatemala. 



The sculpture of the median segment is variable. In some 

 specimens in the British Museum the punctures are more diffuse, 

 only apically and laterally confluent, forming transverse rugosities; 

 in others the pxmctures are more coniiuent, the greater part of 

 the segment being coarsely transrugose. The punctures appear 

 to be more distinct in the rT c? than in the $ 5 . 



*S'. annulator Brull., $ S ; the tyiDCS are in the British 

 Museum, and certainly belong to the present species. $ : length 

 25 mm. ; terebra 27 mm. ; abdomen, anterior legs, and hind 

 tibife rufescent. S '• length 23 mm. ; the front legs and hind 

 tibiae red. 



*S'. hrasiliensis Westw., 5 . Type in British Museum.. This 

 is a very small specimen, only 17 mm. long, terebra 20 mm., 

 with abdomen and all tai^si rufescent. I cannot find any 

 specific difference irom furcatus Lep. & Serv. 



This species is said to be the least rare of the family. It can 

 be distinguished fi'om S. sickmanni Schlett. by the raised 

 posterior margin of the head, sculpture of thorax, and longer 

 terebra. It also superficially resembles ITemistephanus mm-- 

 ginalis Schlett., but may be at once distinguished by the 

 neuration of the wings.
