728 MR. E. A. ELLIOTT ON THK 



joints normal- Neck coarsely transrugose, semiannular distinctly 

 transrugose and finely punctate, with smooth posterior margin. 

 Mesonotum coarsely and irregularly rugose-punctate. Scutellum 

 centrally smooth, laterally with diffuse to dense and partly con- 

 fluent punctures, lateral lobes smooth in front, densely and 

 confluently punctate behind. Mesopleurse above distinctly 

 alutaceous, shining smooth, with diffuse punctures below ; meta- 

 pleui-as diffusely punctate, more densely in front, separated from 

 median segment by a very shallow and alutaceous sulcus. Median 

 segment rather coarsely and diffusely punctate, longitudinally 

 rugose round insertion of petiole, marginal furrows indistinct. 

 Petiole centrally smooth, basally and apically somewhat rugose, 

 shorter than remainder of abdomen, which is apically dull. Terebra 

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

 legs with coxse coarsely transrugose above, laterally more irregu- 

 larly ; femora subglabrous, bidentate ; tibiae compressed not quite 

 to middle. 



Black; cheeks pale marked ; antennae, mandibles basally and 

 the legs, especially about the joints, tend to become rufous. 

 Wings almost hyaline. 



Length 24-25 mm. 



Habitat : Georgia, U.S.A. Type in Royal Nat. Hist. Museum, 

 Berlin. Named after Prof. Franz Sickmann, of Iburg, Hanover. 



This species resembles small individuals of S. fui^catus Lep, k 

 Serv., from which it differs in the shorter petiole and terebra, 

 and sculpture of prothorax and mesonotum. For differences 

 between this species and S. hicolor Westw., see the latter species. 

 It bears also a great resemblance to //. marginalis Schlett., but 

 is easily distinguished by the neuration and by the reflexed 

 posterior margin of head in latter.

5 . Head coarsely and irregularly rugose, a central longitu- 

 dinal trans-striate sulcus on occiput ; posterior mai^gin of head 

 simple ; temples finely punctate, prominent and glabrous above. 

 Second and third flagellar joints of equal length and a little 

 longer than first. Neck short, with three strong trans-carinae ; 

 semiannular finely trans-striate, its posterior margin narrowly 

 smooth ; mesonotum coarsely punctate ; scutellum. smooth, with 

 diffuse and rather fine puncturation. Meso- and meta-pleurae 

 alutaceous and dull, with a few punctures, latter separated from the 

 median segment by a sulcus. Median segment scabriculous and 

 centrally trans-striate. Petiole trans-striate, as long as rest of 

 abdomen ; apical segments discally emarginate. Terebra slightly 

 longer than body, sheaths unusually stout and abrviptly pointed, 

 ferruginous, with a white band before the equally broad black 

 apex. Hind legs with coxae elongately pilose and sparsely trans-
