HYMENOPTEEOUS FAMILY STEPHANID^. 727 



Enderlein appears not to have given the size of this species, 

 but as he compares it with S. ceylonicus Cam. and S. hcematipoda 

 Montrz., it is probably about 28-30 mm. The former of the 

 above species is said to resemble the present one in colour, with 

 the same spot on the outer orbits, but the sculpture of the meso- 

 and meta-pleurfe difiers, the petiole is black, and the wings have 

 a steely iridescence.

$ . Frons somewhat coarsely and irregularly rugose ; occiput 

 transrugose, coarsely in front, more regularly towards the eyes. 

 Temples finely but distinctly obliquely rugose, with a smooth 

 space behind eyes. Posterior margin of head simple. Second 

 flagellar joint twice as long as first, third a little shorter than 

 first and second together. Neck rather coarsely transrugose ; 

 semiannular finely but distinctly obliquely rugose. Mesonotum 

 coarsely and confluently punctate, the usual median row of 

 punctures wanting and the two lateral impressions represented 

 by indistinct rows of punctures. Scutellum coarsely and difi"usely 

 punctate. Mesopleurse above finely alutaceous and dull, beneath 

 slightly shining and difi:usely punctate ; metapleurae dull, finely 

 and diftusely punctate, separated from median segment by a deep 

 and dull sulcus. Median segment diffusely but deeply punctate, 

 apically transrugose and with distinct lateral sulci. Petiole 

 trans-striolate, basally more irregularly rugose, shorter than rest 

 of abdomen, which is discally dull, laterally shining. Terebra 

 as long as body, sheaths white-banded before apex. Hind legs 

 with coxse trans-striolate; femora shining smooth, bidentate ; 

 tibiae constricted not quite to middle. 



Black ; cheeks pale marked ; the anterior legs, especially the 

 tarsi, tend to become brownish. Wings hyaline. 



Length 19-20 mm. 



Habitat : Colombia. Type in Royal Nat. Hist. Museum, 

 Berlin. 



This species differs from ;S'. acutus Lep. & Serv. in the simple 

 posterior margin of head, coarser puncturation of mesonotum, and 

 shorter petiole. From S. niger Smith it may be known by the 

 finer sculpture of the frons, obliquely rugose temples, and rugose 

 semiannular.

5 . Frons coarsely and irregularly rugose ; occiput anteriorly 

 arcuately, posteriorly transversely, and laterally irregularly 

 rugose. Temples with a few apical punctures. Posterior margin 

 of head simple. Cheeks slightly longer than scape. Basal flagellar
