shorter than the remaining segments together, also shorter than 

 the hind coxse, trochantea's and femora together ; rest of abdomen 

 basally rugose, thence dull to apex. Terebra longer than body, 

 its sheaths white-banded before apex. Hind legs with coxse 

 plainly ti-ans-striate above, laterally coriaceous and shining ; 

 femora internally shining, externally and above almost shining, 

 slightljr rugose behind, bidentate ; tibiae longer than femora, 

 compressed in basal third. 



Black ; cheeks pale marked, mandibles and antennae basally 

 ferruginous, temples tending to bi'ownish ; abdomen brown, 

 petiole rufescent ; legs more or less rufescent. Wings slightly 

 infumate throughout. 



Length 17 mm. ; terebra 21 mm. 



Habitat: Hungary. Forster's type is in the State Museum 

 at Budapest. 



Distinguished from serrator Fab. by the three-jointed hind tarsi, 

 white-banded terebral sheaths, etc. From S. sickmanni Schlett. 

 it may be known by the rugose, not punctate metapleurse, 

 coriaceous petiole, and longer terebra.

5 . Frons arcviately to irregularly rugose ; occiput anteriorly 

 arcuately, posteriorly rather coarsely transversely, laterally more 

 irregularly rugose. Temples verj^ diffusely punctate. Posterior 

 margin of head simple. Cheeks a little longer than scape. Basal 

 flagellar joints normal. Neck rather coarsely transrugose ; 

 semiannular iinely transrugose and sparsely punctate. Meso- 

 notum rather coarsely punctato-rugose. Scutellum smooth, 

 with a few punctures on outer margin onl}'. Mesopleurae above 

 alutaceo-rugose, below somewhat densely punctate ; metapleura^ 

 irregularly rugose, separated from the median segment by a 

 nearly smooth sulcus. Median segment rather densely punctate 

 centrally, laterally more diffusely, oblique to transverse rugose 

 round insertion of petiole, crenulate marginal sulci distinct. 

 Petiole basally irregularly, otherwise transversely striate, shorter 

 than remainder of abdomen, which is entirely dull. Terebra 

 evidentlj' longer than body, sheaths white-banded before apex. 

 Hind legs with the cox?e laterally coarsely and irregularly, above 

 indistinctly, apically decidedly transrugose ; femora slightly 

 shining, bidentate ; tibise compressed to middle. 



Badious ; head and thorax ferruginous, remainder of body red- 

 brown ; petiole more or less nigrescent. Wings slightly infumate. 



Length 15-22 mm. Habitat: Kentucky, Georgia, U.S.A. 



This species may be known from S. sickmanni Schlett., which 

 it much resembles, by the longer terebra, sculpture of meso- and 

 meta-pleurfe and of petiole, which is rugose throughout, not 

 centrally smooth. The coloiu" is also distinctive, being a decided 

 red-brown or chestniit, S. sickmanni being deep black.
